DANGER
CAUTION
These safety alert symbols identify important safety messages in this manual. When you see these symbols, be
alert to the possibility of personal injury and carefully read the message that follows.
Do not allow anyone to operate the CRACK SAW without first reading this Operator Manual and becoming
familiar with its operation. The manufacturer of the CRACK SAW has gone to great extremes to provide the
owner(s) and/or operator(s) with the finest equipment available for its intended job function of removing covering
materials from concrete and wood floor surfaces. Yet, the possibility exists that the CRACK SAW can be utilized
in and/or subjected to job applications not perceived and/or anticipated by the manufacturer. Such misuse and/or
misapplication of the CRACK SAW can lead to the possibility of serious damage, injury or even death. It is the
responsibility of the owner(s) and/or operator(s) to determine that the CRACK SAW is being utilized and/or
operated within the scope of its intended job function. It is the responsibility of the owner(s) and/or operator(s) to
establish, monitor and constantly upgrade all safety programs and/or practices utilized in and for the operation of
the CRACK SAW. The purpose of such programs is to provide for owner(s') and/or operator(s') safety. Operators
must be instructed to recognize and avoid unsafe conditions associated with their work (29 CFR 1926.21 (b)(2))
and/or applicable updated revisions. It is the responsibility of the owner(s) and/or operator(s) to determine that no
modifications and/or alterations have been made to the CRACK SAW. Modifications and/or alterations can lead to
the possibility of serious damage, injury or even death. It is the responsibility of the owner(s) and/or operator(s) to

NOTICE TO OPERATORS
CAUTION
The concept of frame mounted type Crack Saws has been successfully utilized for many years as a
practical solution to many types of random crack sawing requirements. The basic concept is proven and
well accepted within the associated marketplaces. Use of a Crack Saw requires strenuous work activity.
This type of work activity can be considered to be greater in magnitude than that experienced with the
use of many other types of both light construction and lawn and garden related equipment. This type of
work activity should only be attempted by operators of adequate physical size and stature, mental
awareness and physical strength and condition. The body parts most noticeably affected during the
planing process are the arms, hands, wrists, shoulders, lower back and legs. The process can also
produce excessive stress/strain directly to the back muscles, spinal vertebrae and many other body
parts. Back related pain can be a side effect of utilizing a Crack Saw. An operator with a chronic back
related problem or a history of back and/or other medically related problems should not attempt to utilize
the Crack Saw. Use of the Crack Saw may only aggravate this and any other medically related problem.
Because of the diverse type of prevailing job applications, job site conditions, operator experience levels
and operator physical characteristics, no warranty, guarantee, representation and/or liability is made by
the manufacturer as to the absolute correctness or sufficiency of any operational procedure, operational
position and/or technique. There is no absolute guarantee that an operator of any given experience level,
physical size and/or physical condition will be immune to the possibility of and/or probable physical side
effects of the normal use of the Crack Saw. Each potential operator must be made aware of and assume
the operational and physical liability described and/or associated with the use of the Crack Saw. Improper
use of the Crack Saw can result in property damage and/or personal injury, including death. Each
potential operator not willing to assume the operational and physical liability described and/or associated
with the use of the Crack Saw, should not operate it. Proper levels of operator experience, skill and
common sense are essential for maximizing the safe and efficient operation of the Crack Saw.
Record the CRACK SAW and electric motor serial numbers in the spaces provided below.

SAFETY PRECAUTIONS
6) Prolonged use of the CRACK SAW (or other,
similar machines) exposes the operator to vibrations
which may produce Whitefinger Disease (Raynaud's
Phenomenon). This phenomenon reduces the
hand's ability to feel and regulate temperature,
produces numbness and burning sensations and
may cause nerve and circulation damage and tissue
necrosis. Antivibration systems do not guarantee
that you will not sustain Whitefinger Disease.
Therefore, continuous and regular users should
closely monitor the condition of their hands and
fingers. After each period of use, exercise to restore
normal blood circulation. If any of the symptoms
appear, seek medical advice immediately.
integrity. Replace each component as necessary.
The arbor shaft rotates at high speed during the
specific process and can be subject to high wear
rates if the installed diamond blade is not properly
maintained and/or replaced at regular service
intervals.
f) Determine that operator controls work freely, all
safety devices are operative and information decals
are readable.
g) Check to see that the Crack Saw and all related

danger of head injuries. Noise, generated by the
operation of the CRACK SAW and the actual
process itself, can damage your hearing. Wear
approved sound barriers (ear plugs or ear mufflers)
to protect your hearing. Continuous and regular
operators should have their hearing checked
regularly.
9) Contact appropriate representatives to determine
if/where electrical cables, gas lines and other
hazardous items are buried under the work surface
BEFORE utilization. The Crack Saw and related
accessories are not insulated. Contact with buried
electrical cables, gas lines and other hazardous
items can result in electrocution and/or an explosion.
10) Know how the controls operate. Know how to

INFORMATION RELATIVE TO THE USE OF
DIAMOND BLADES.
Safety requirements always override performance
considerations. Diamond blade technology has
made such rapid advances during the past few
years that a diamond blade, properly used, on well
designed and well maintained equipment, can
provide the lowest cost per cut of any of the
methods of cutting now in use. But, put that same
blade onto a piece of poorly maintained equipment
and in the hands of a poorly trained operator and the
cost of cutting can virtually put you out of business.
3) Using the funnel, fill the fuel tank with fresh, clean
fuel according to the specifications outlined in the
material supplied by the engine manufacturer. Do
not overfill the tank or spill any fuel. If the fuel tank
incorporates a screen mesh to prevent debris from
falling into the tank, do not remove to increase the fill
rate. Replace the filler cap. Wipe away any excess
spilled fuel.
DANGER
The members of the Saw Manufacturer's Institute
have been a significant contributor to the state of the
diamond blade art. We hope that some of the
knowledge and experience that we have
accumulated in our many years in the business can,
through this booklet, assist you in keeping your cost
down to an absolute minimum.

Of all the problems that confront diamond blade
users, blade wear is the most difficult to accurately
evaluate. Reporting life performance of identical
diamond blade specifications operating under
seemingly identical conditions tend to be
inconsistent.
Operation
THEORY OF OPERATION.
The RCC130H Crack Saw operates on the principle
of transmitting horsepower through
transmission directly to an industry standard, 8 inch
diameter, diamond segment blade of various widths.
a
V-Belt
Masonry blade operators frequently report blade life
in terms of hours, days or weeks. However, these
reports neglect to mention type of material being cut,
the size of the cuts, and the number of cuts per day.
In addition, the amount and the cleanliness of the
water and the amount of pressure the operator
applies to the cut have an effect on blade life.
The crack sawing process is directly controlled by
these conditions:
a) The use of a suitable mechanism (diamond blade)
of proper design and configuration to penetrate the
work surface and remove material while delivering
acceptable service life.
Obviously, trying to compare the life of one diamond
blade with another, simply on the basis of hours, is
analogous to trying to compare a set of tires on one
car with an identical set on another car...it is virtually
impossible. There are just too many variables...the
weight of the car, the types of roads driven on, the
condition of the car...particularly the suspension, the
manner in which the operator handles the car, etc.
Just as many variables apply to diamond blades.
b) Sufficient static weight supporting the diamond
blade to allow it to effectively penetrate the work
surface and remove material.
c) Adequate horsepower capable of rotating the
diamond blade at industry recognized speeds
against the work surface to deliver acceptable
productivity rates.
So, the next time you have reason to compare blade
life, keep these variables in mind. Some of the
problems arising from these variables can be quickly
identified, and possibly corrected"...
Since no two materials are exactly alike, no two
work surface materials can be sawed by the exact
same method. The nature of the sawing process,
along with operator experience, skill and common
sense, would suggest that efficient and productive
crack sawing is a matter of trial and error.

matches the one on the equipment. Do not force the
blade onto the spindle. Do not use an arbor shaft
(spindle) and blade combination of different sizes.
Proper fit is achieved when the blade slides onto the

General Information.
8) Always make sure that the equipment used is in
good operating condition in accordance with the
manufacturer's specifications. Do not operate the
equipment unless the guards are in good condition,
in the proper place and secure. If the equipment
appears to be missing any fasteners or has any
parts that appear loose or worn, do not operate the
equipment until the appropriate repairs are
performed. Always make sure the blade you intend
to use with the equipment meets all the equipment
manufacturer's specifications.
1) " Only mature, properly instructed adults should
be permitted to operate machinery and tools.
2) Only utilize the blade to cut the material it is
designed and intended to cut. Blades intended for
masonry material (stone, concrete bricks, blocks) or
blades for steel or ductile iron must only be used in
those materials. If you need to cut a material other
than the ones listed above, you must use a blade
that has been designed for that specific material.
Use of a blade in the wrong material may involve a
considerable safety risk. It may also reduce the life
of the blade or damage the blade.
9) Do not operate the equipment with other than the
recommended blade sizes. This can result in severe
blade damage. Contact the machine manufacturer
for advice.
3) Inspect all diamond blades for damage before
use.
10) Make sure that the spindle speed on the
machine does not exceed the maximum RPM
indicated on the diamond blade. This can result in
blade breakage. Check the blade shaft with a
tachometer to verify that the equipment's maximum
RPM does not exceed the manufacturer's
specifications.
4) Never use a new or used diamond blade that
shows damage such as cracks, missing segments,
damage to the arbor hole or by the flange washers,
or other appearances not consistent with the
appearance of a new blade. These are indications of
previous improper use. If you have any doubt about
the safety of a blade, contact the Customer Service
Department of the blade manufacturer for
assistance. If you do not know the name of the blade
manufacturer, contact the Customer Service
Department of General Equipment Company for
assistance. There is no charge for this service.
11) Blades designed for wet cutting must be cooled
by an adequate, continuous water flow to each side
of the blade. Lack of enough coolant will cause
excessive heat, poor blade performance and
possible segment loss.
5) Always check that the two mounting flanges are
of the same diameter and that they are clean and
flat. The flanges should not have any cracks or show
any abnormal wear. Make sure that the arbor bolt or
nut is the correct one for the equipment without
damage to the threads. Improper or damaged flange
washers and/or damaged fasteners can damage the
12) Blades designed for dry cutting may be used
without water coolant. However, dry cutting blades
can overheat which will result in loss of blade
tension and may ruin the blade. The risk is greatest
during long continuous cutting. Most overheating
problems can be avoided by lifting the blade out of

outlined in the Material Safety Data Sheet (MSDS).
This product as sold presents no hazard although,
during use, small amounts of these metal
substances may be released into the dust or slurry
generated from the material being cut or ground.
Prolonged exposure to excessive amounts of dust
and slurry may cause respiratory disease, skin
irritation or cancer.
13) Do not force the tool into the material to be cut.
A properly working diamond tool will grind the
material without excessive force being applied. If
excessive force is needed, it indicates there is
damage to the blade to the blade or the wrong blade
is being used.
14) Always inspect the diamond blade and the
equipment any time you stop during the cut. If you
notice any difference in performance as your work
progresses, immediately STOP and inspect the
equipment and the diamond tool.
Common Sense.
Almost all accidents are avoidable if you apply
caution and common sense. Follow all safety
precautions at all times. If you are not sure...simply
don't do it. Ask for advice. Used improperly or
carelessly any tool is dangerous and may cause
severe bodily injury or death. If tools are used with
caution, proper techniques and common sense, they
will do an excellent job for you"...
15) Do not operate any diamond tool without full
knowledge about appropriate cooling of the tool. If a
tool is not cooled properly, the blade core can
become damaged resulting in the segments coming
loose or the blade core (the steel) breaking. This
can result in serious bodily injury or death to the
operator or bystander.

1) The Crack Saw is of a downcut type design as
viewed by the operator. The diamond blade is
intended to rotate toward the operator to enhance
visibility and overall productivity while following a

substantially enhances machine control and reduces
fatigue as long as the diamond blade does not come
in direct contact with a protruding obstruction from
the floor. Direct contact with such an obstruction can
result in rapid and jerky directional movement of the
machine. In most operating situations, direct contact
with a protruding obstruction from the floor will result
in serious damage to the diamond blade. This
occurrence may not allow the operator to remain in

DO NOT MODIFY THE ORIGINAL OPERATING
CONFIGURATION FOR THE LOUVERS FOR ANY
REASON. MODIFICATIONS TO THE LOUVERS
CAN RESULT IN PROPERTY DAMAGE AND/OR

6) Following the random crack direction and/or
pattern with the blade is accomplished by viewing
the blade and crack in the louvered opening in the
blade guard. The louvers are intended to provide
protection for the operator in the event that a
diamond segment becomes separated from the
blade blank. Probable causes for such occurrences
are discussed in detail in the Troubleshooting
section of this manual.
7) Proper operator posture and stance will enhance
operational safety and overall productivity. FIGURE
24 depicts a proper operator's position. FIGURE 25
depicts an improper operator's position that can
accelerate fatigue, decrease productivity and reduce
safety. The downcut orientation of the diamond
blade will normally produce a "self-propelled" effect
against the operator. This effect is intended to
reduce the operator fatigue associated with the
operation of the machine and to increase overall
productivity.
a) The geometric design of the louvered blade guard
is intended to provide
a
high mathematical
percentage of protection for the operator in a normal
operating position as described in this manual. The
mathematical percentage will decrease for operating
positions not described in this manual.
8) In some operating conditions, it may be
necessary for the operator to apply a resisting force
(push) against the operator handle to counteract the
"self-propelled effect. In some other operating
conditions, it may be necessary for the operator to
apply a force (pull with) to the operator handle in
order to assist the sawing action of the Crack Saw.
b) In the event of diamond segment separation from
the blade blank, there is a high mathematical
probability that the segment will be thrown forward
against the dust pan located under the main frame
or directly against the forward (non louvered) section
of the blade guard.
The manufacturer has
conducted extensive testing to substantiate this
theory. In actual field tests, diamond segments were
purposely separated from the blade blanks through
abusive operational techniques. In all field tests, no
separated diamond segments made direct contact
with the blade guard louvers.
c) In the very low probability that a diamond
segment would make direct contact with the blade
guard louvers, the geometric design has a high
mathematical probability to not allow the segment to
penetrate the vertical plane as defined by the
location of the louvers. The spaces, angle
orientation and number of louvers minimize the
mathematical probability that
a
segment can
penetrate the vertical plane, exit the louvers and
eventually strike the operator.
d) The geometric configuration of the louvers are
designed to allow for adequate and/or proper
visibility for the operator during the sawing process.
With use, concrete and/or asphalt dust will
accumulate at the bottom of the blade guard
opening. At regular intervals, this material should be
removed to enhance operator visibility during the

10) The wide variety of potential work surface
materials along with the corresponding variety of job
site environments, make it impossible to develop a
standardized operating procedure for the Crack
Saw. Use of the Crack Saw will require constant trial
and error testing until satisfactory results are
achieved. Experience gained over time and common
sense will help minimize the amount of necessary
testing. Many factors will directly affect the operating

parameters and/or techniques utilized for
a
specialized job application. Some of these factors
include:
d) Tensile strength of the material being sawed.
e) Matrix material of the diamond blade segments in
consideration of the aggregate type, amount and/or
hardness contained in the material being sawed.
f) Service condition of the diamond blade segments.
a) Work surface material yield and tensile values. As
a general rule, these values will determine material
removal rate per unit of time. Materials with high
yield and tensile values will characteristically
resist/limit material penetration. For such materials,
the accepted procedure is to make a number of
multiple passes over the work surface rather than
attempt to make a single, deep pass. The net effect
is to actually increase productivity: more material
removed in less time. Other added benefits to this
technique are decreased vibration, less operator
fatigue and increased component service life.
g) Operating RPM speed range for the diamond
blade.
9)For normal job applications, operate the engine at
a maximum, governed speed of 3450 RPM. Consult
the material supplied by the engine manufacturer
and the Specifications section for specific
information. If you have any questions regarding
specific job applications, contact the Customer
Service Department for information. There is no
charge for this service. Additional information can be
obtained from the Masonry and Concrete Saw
Manufacturers Institute, 30200 Detroit Road,
Cleveland, OH 44145-1967.
b) The width of the random crack in comparison to
the required cutting width and depth. For example, if
the random crack has an average width of 1/8 inch,
productivity rates will be greater with the use of a 1/4
inch wide blade over that delivered by a 1/2 inch
wide blade. The same analogy can also be used for
the cutting depth. Productivity rates will be greater
for a 1/2 inch deep cut than a 1-inch deep cut.
Deeper cuts also require additional time for the
blade to "clear itself" when following a random crack
pattern.

These types of patterns can be properly sawed by a
multiple step process. A segment of the crack is first
sawed by the described process (FIGURE 32) and
the machine repositioned by the described
procedure to saw the intersecting segment. FIGURE
33. This procedure can be repeated as necessary
by the geometry of the specific random crack
pattern. Following this procedure is especially
important when deep (greater than 1/2 inch) saw
cuts are required for proper crack filling methods. By
utilizing this operating procedure, intricate random
crack patterns can be properly sawed while
maximizing operator control, overall productivity and
extending blade service life.
14) Generally speaking, the majority of random
crack patterns follow a predominantly straight line
with no more than 20˚ variance from an imaginary
center line. FIGURE 30. These random crack
patterns are easily sawed to the required widths and
depths by the properly described diamond blades.
FIGURE 30
However, there are many instances where the
random crack pattern follows perpendicular (90˚) to
more obtuse (91˚ to 179˚) angles. FIGURE 31.
These angles will generally not allow the Crack Saw
to properly follow the resulting patterns without
significantly reducing operator control, overall
productivity and causing severe damage the

b) It preserves the pavement adjacent to the
cracking. Cracks that are properly cleaned and
sealed contain filler materials that firmly adhere to
the crack sides during times of both expansion and
contraction. Without the addition of these filler
materials, the adjacent pavement would have
increased exposure to the elements, resulting in
increased oxidation of the binder, hardening and
secondary cracking along the main crack.
STOPPING THE RCC130H SERIES GASOLINE
POWERED CRACK SAWS.
1) Position the quick change height lever over center
to its rear most (up) position.
2) Stop the Crack Saw by moving the engine throttle
control lever to the idle speed position. Turn the
ignition switch located on the engine to the OFF
position. Consult the material supplied by the engine
manufacturer for specific information.
c) It eliminates the damaging effects of
incompressibles such as sand, aggregate and dirt.
When these materials get into a crack they can
restrict crack closure during periods of warm
weather. The resulting compressive stresses at the
faces can create spalling and loosening. In some
highly oxidized pavements these stresses can even
create pavement lipping, which is the upheaval of
pavements at their transverse cracks.
OPERATIONAL PARAMETERS AND
TECHNIQUES FOR THE RCC130H SERIES
CRACK SAW.
Basic definitions.
There are very few aspects of the pavement
maintenance industry that all members, including
contractors, engineers, researchers and government
agencies can agree on except the inevitability of
cracks forming in all types of pavements. To
properly address the crack repair procedures,
contractors must have a basic understanding of why
crack repair is beneficial, crack types to address and
the repair materials and methods available.
d) It extends pavement life. Sealing procedures
allow the contractor to effectively exert control over
the base and sub-base conditions, pavement
interference and crack growth, thereby extending
the pavement's service life.
Types of Cracks.
There are several basic types of cracks:
a) Reflective. This type of crack appears primarily in
resurfacing projects, although it can also occur in a
new pavement surface. Reflective cracks occur
when an existing crack or joint in the underlying
pavement structure reflects upward through the
surface.
A basic understanding of the difference between
crack filling and crack sealing and the working
knowledge to understand which one is appropriate
for a specific job application is essential for any
pavement maintenance contractor.
An industry accepted definition of crack filling is the
placement of materials into cracks to reduce water
intrusion and reinforce the adjacent pavement.
Crack sealing is the placement of specialized
materials either above or into working cracks to
prevent the intrusion of water and incompressibles
such as sand, aggregate and dirt.
b) Joint. A joint is the edge of the individual paving
pass made during construction. Such construction
joints usually have a lower density than the
remaining material. When the placed mats do not
bond properly (for any number of reasons), joint
cracks can appear.
Why Do It at All?
c) Slippage. Slippage cracks are usually crescent
shaped and are created by heavy traffic that is either
Crack sealing is used as a first line of defense
against the deterioration of pavement because of its
inherent benefits:
stopping, turning or climbing a hill.
Resultant
stresses can cause a bond failure between upper
and lower pavement layers. The open end of the U
shaped crack always points in the direction of the
applied force.
a) It protects the base and sub-base. A good
pavement requires a base and sub-base of high
structural
integrity.
Effective
crack
sealing
d) Thermal. All pavements expand and contract due
to temperature variations. This movement can
create cracks. To better allow for movement,
pavements need to be constructed with the correct
percentage of air voids, which provide for internal
stress relief. When the air void percentage is not
correct, thermal cracks appear.
procedures eliminate water from entering and
weakening these areas. The resulting weakness
can result in the loss of structural support, which can
then further result in the formation of additional
cracks and settling around the crack area.

e) Fatigue or alligator. Over time, as a pavement
Preparation and Application.
surface ages, it becomes more rigid and has less
ability to tolerate vertical load deflections. This
occurrence creates a tension and pulling apart in the
pavement and results in alligator type cracking.
Such cracking can also occur from improper
structural capacity and aging. It is generally
recommended that alligatored areas be removed
and replaced rather than be filled or sealed.
The primary purpose of the Crack Saw is to produce
a proper configuration in the crack area for the
placement of the sealing material. The exact
configuration is dependent upon many factors
including crack type, pavement downtime and
budget
restrictions.
There
are
numerous
configurations, although all can be grouped into four
general classifications:
f) Block. This type of crack forms a square pattern,
with cracks intersecting at approximate right angles.
A common cause of block cracks on asphalt
pavements is a lack of traffic, which constantly
kneads the pavement and keeps it flexible. Other
causes can include excessive air voids in the
material.
a) Flush fill. The material is simply dispensed into an
existing unsawed crack and the excess struck off.
b) Reservoir. Material is placed only within the
confines of a sawed crack, either flush with or
slightly below the pavement surface.
c) Overband. Material is placed into and over an
unsawed crack and shaped into either a band aid
configuration (3 to 5 inches wide and 1/8 inch thick)
or given a slight cap.
g) Edge. Edge cracks appear only parallel to and
within usually 18 inches of the pavement edge.
Cause can include substandard base, lack of
shoulder support, inadequate drainage or damage
caused by frost.
d) Combination. Material is placed into and over a
sawed crack, then is shaped by squeegee into a
band centered over the crack reservoir.
Equipment and Materials.
Pavement contractors can select from a wide variety
of hot or cold applied materials to seal cracks. Unlike
cold materials, hot applied sealers are first prepared
prior to application. The standard method is a double
boiler kettle, which consists of an inner chamber that
contains and agitates the sealant material and an
outer chamber serving as the heat source.
The configuration of the random crack ultimately
determines the specific type and/or quantity of
material utilized in the process.
Heated sealers include rubberized asphalt, low
modulus rubberized asphalt, fiberized asphalt and
asphalt rubber. Cold applied materials are usually
comprised of a self leveling silicone and modified
emulsions.
When making a material selection, the pavement
contractor must consider many factors. It is critical
that the material be placed efficiently and deliver
satisfactory performance given the related
environmental factors. Other significant factors
include preparation and cure times, adhesiveness to
the crack sides, cohesiveness in the crack center,
resistance to softening and flow, aging and
weathering.

The normal operation of the Crack Saw produces
extreme dirt and dust, along with levels of random
vibration. Before operating the Crack Saw, the
following service list should be accomplished. This
list is for reference only and is not intended to be all
inclusive. Other subject areas can be added at the
discretion of the owner(s) and/or operator(s):
1) Check all fasteners for proper torque values. If a
fastener requires retorquing, consult a torque chart
for proper value. Properly discard and replace any
worn fastener with a factory approved, replacement
part.
CHECKING V-BELT TENSION AND ALIGNMENT.
Application: All Models.
Proper V-belt tension and alignment is essential for
smooth transmission of horsepower and extended
service life. Improper tension and alignment will
accelerate V-belt wear and contribute to decreased
productivity. The V-belt is tensioned at the factory
with the maximum recommended tension force.
Check the belt tension at least two times during the
first day of operation as there will normally be a
rapid decrease in belt tension until it has been run
in. Check the belt tension every eight hours of
operation thereafter and maintain tension within the
recommended range. The correct operating tension
for a V-belt drive is the lowest tension at which it will
not slip under peak load conditions.
2) Check the V-belts for wear. Adjust or replace as
necessary. Check pulleys for wear and proper
alignment. Many loose materials created as a result
of operating processes can be extremely abrasive.
3) Keep the Crack Saw clean. Wash the unit after
each use. Keep loose materials from accumulating
around engine cooling fins. Determine that the
interior sections of the frame are free of material
build-up. Such a build-up can restrict the operating
process and present a potential safety hazard.
Clean and remove any material build-up from the
Crack Saw after each use.
Tools Required:
1 each, 16 inch minimum length straightedge.
1 each, 10 lbs minimum capacity, tension scale or
belt tension tool.
4) Engine service life can be extended with proper
air cleaner maintenance. Consult the material
supplied by the engine manufacturer for specific
information.
1) Position the Crack Saw on a suitable work bench
with the V-belts approximately at waist level.
5) Check for proper oil level. Always use clean, high
quality engine oil. Change oil as required. Consult
the material supplied by the engine manufacturer for
specific information.
2) Disconnect the engine spark plug wire.
3) Remove the belt guard from the main frame.
Clean the inside of the belt guard with an
appropriate solvent. Check for signs of wear and
damage. Secure in a proper storage area.
6) Remove material accumulations from the exterior
surfaces of the electric motor. The electric motor is a
totally enclosed, fan cooled (TEFC) design. Keep
the fan fins clear of material accumulations to
enhance air flow over the motor exterior for cooling
purposes.
CAUTION
Observe all applicable safety precautions for the
solvent.
4) Check the belt tension using the spring scale or
belt tension tool midway between the engine/motor
pulley and the arbor shaft pulley. Belt tension should
measure approximately 0.22 inch at 3-1/4 to 4-3/8
lbs. measured force range. FIGURE 35. If tension is
within specifications, proceed to Step 5. If tension is
not within specifications, refer to INSTALLING A

9) Apply increased belt tension by progressively
tightening the take-up capscrews against the
engine/electric motor.
a) Do not install replacement belts if the pulleys
have excessively worn grooves. Such pulleys should
be replaced to insure proper belt fit. Operating the V-
belts in worn pulley grooves will accelerate wear,
reduce horsepower and torque levels and
significantly reduce component service life.
a) Recheck V-belt alignment.
b) Check belt tension with the spring scale or belt

LUBRICATION REQUIREMENTS.
Application: All Models.
Parts Required:
14) Rotate the arbor shaft by hand to determine the
amount of bearing preloading created as a result of
the installation process.
Properly installed replacement bearings should
rotate without excessive friction, drag and/or "rough
spots". If these symptoms occur after assembly, the
bearings were improperly supported when pressed
into the bearing block. The resulting thrust placed
upon the bearing exceeded the static capacity.
Bearing operating with these characteristics will
deliver minimal service life and be prone to
premature failure.
1 each, standard grease gun filled with one of the
following: ESSO Beacon 325, Shell Alvania #2,
Chevron SRI, or equivalent.
1 each, container of dry film lubricant.
1) Lubricate the rigid caster wheel bearing with a dry
film lubricant only. Dry film lubricants dry
immediately upon contact. Use sparingly. Excess
lubricant will attract the fine grained, powdered
materials described in this manual and directly affect
bearing service life.
15) Inspect the hub body drive key and hub body for
wear and/or damage. Replace any questionable
component with a factory replacement part only.
Reinstall the hub body drive key into the arbor shaft.
Reinstall the hub body to the arbor shaft until it fully
seats against the inside bore of the bearing.
Reinstall the two Allen screws into the hub body and
properly torque.
CAUTION
Do not lubricate the rigid caster wheels with any
type of grease material. Grease will attract
foreign material accumulations that can
accelerate bearing wear.
16) Inspect the arbor shaft drive key and arbor shaft
pulley for wear and/or damage. Replace any
questionable component with a factory replacement
part only. Reinstall the arbor shaft pulley drive key
into the arbor shaft. Reinstall the arbor shaft pulley.
Do not torque the Allen screws at this time. The
Allen screws will be tightened after determining that
the engine/electric motor and arbor shaft pulleys are
in proper alignment. See Step 19.
2) The arbor shaft is supported by extra capacity,
ball bearings. These bearings are lubricated at the
time of manufacture and do not require additional
servicing when placing the unit in initial service or
during their normal service life. During the first few
hours of service, lubrication material may seep from
the bearings. This should not be a cause for
immediate concern.
17) Reassemble the bearing block to the main
frame. Determine that the arbor shaft rotates
perpendicular to both the vertical and horizontal
planes as defined by the direction of machine travel.
3) The swivel wheel casters are sealed to minimize
the potential for dust contamination. Lubricate the
swivel caster wheels with the grease gun. Use
sparingly. Excess lubricant will attract the fine
grained, powered materials described in this manual
and directly affect bearing service life.
18) Follow the instructions as outlined for
INSTALLING
A
REPLACEMENT V-BELT OR
PULLEY to complete the assembly of the pulleys, V-
belts and belt guard.
4) Do not apply belt dressing materials to the V-belts
for the purpose of minimizing slippage. These

TROUBLESHOOTING
DIAMOND SEGMENT LOSS
Troubleshooting
a) The Crack Saw is not being held firmly by the
operator, causing the blade to twist or jam in the
work surface. Hold the Crack Saw firmly.
ENGINE FAILS TO START
Ignition switch in OFF or cut off position. Place
switch in the ON position or move throttle control
lever to the ignition operational position.
Incorrect carburetor/fuel ignition system adjustment.
See Service section.
b) Overheating due to inadequate supply of coolant
(air or water). This is usually accompanied by
discolorations which appear on the blade blank in
the area of the segment loss. If wet sawing, provide
adequate water flow to both sides of the blade.
Determine that no water line blockage exists. If dry
sawing, periodically allow the blade to run out of the
saw cut for up to 20 seconds for every minute of
sawing. This will allow the blade to properly cool
before resuming sawing operations .
Air filter blocked. See Service section.
Ignition wire to spark plug loose or disconnected.
Reconnect.
Fuel supply exhausted. Refill the fuel tank.
ENGINE LOSES POWER
c) The blade blank wears thin as a result of
undercutting by abrasive fines generated by the
sawing process. The blade blank wears to a knife
edge which weakens the blank and causes a
segment to separate. If the fines are highly abrasive,
wear resistant blanks should be utilized to retard the
undercutting phenomenon. Inspect the blades
periodically during usage for this occurrence. If wet
cutting, allow for ample water to flush the fines out of
the saw cut.
Incorrect carburetor/fuel injection adjustment. See
Service section.
Water in fuel supply. Drain and replace fuel.
Excessive carbon accumulation in combustion
chamber. See Service section.
Fuel tank breather vent closed (if so equipped).
Open vent.
Air filter system blocked. See Service section.
d) Improper clamping action by the arbor shaft hub
body and hub flange causes the blade to flutter in
the cut or fail to support the blade in proper
alignment.
Always
clean
foreign
material
accumulations from the flange surfaces. Replace the
flanges if they become bent or deformed with factory
approved replacement parts only.
OPERATIONAL PROBLEMS.
DANGER
ALWAYS UTILIZE DIAMOND BLADES IN
COMPLIANCE WITH ANSI B7.1, ANSI B7.5
e) The blade can be too hard for the specific
material being sawed, causing excessive dullness
and segment separation due to impact loads and/or
fatigue. This occurrence can also be the direct
cause of frictional heat which can melt the brazing
filler material that secures the segments to the blade
blank. Use a proper blade specification for the
material being cut. Match the segment matrix
composition to the specific aggregate material being
sawed.
AND/OR
LATEST
REVISION(S)
AND
APPLICABLE OSHA REGULATIONS. IMPROPER
USE OF DIAMOND BLADES CAN RESULT IN
PROPERTY DAMAGE AND/OR PERSONAL
INJURY.
Copies of ANSI B7.1 and B7.5 for review and
education purposes can be obtained from the
American National Standards Institute, 1430
Broadway, New York, NY, 10018. Copies of the
applicable OSHA regulations governing the use of
powered equipment and diamond blades can be
obtained from your nearest OSHA office.
f) The blade rotation while sawing is out of round
(not concentric), resulting in direct impulse loads
being applied to the segments. Replace worn
machine components including bearings and arbor
shaft.
g) Improper blade rotational speed which produces
excessive pressure on the segments and
subsequent failure of the brazed/welded joint, blade
blank or segment itself. Determine that the blade is
being operated within the industry recommended
RPM speed range. Engine RPM should be checked

TROUBLESHOOTING
periodically with an electronic tachometer to ensure
proper operational speed for the blade.
BLADE WILL NOT CUT
a) Blade matrix composition is too hard for the
material being sawed. Utilize a blade with a softer
matrix composition.
UNEVEN SEGMENT WEAR
a) If wet sawing, insufficient water flow to one side of
the blade which effectively reduces the side
clearance. Flush the water system. Determine that
water is being adequately and equally distributed to
both sides of the blade.
b) Blade has become dull, probably as a result a
hard matrix composition being utilized to saw a hard
material. Dress or sharpen the blade by utilizing it to
saw a softer material to expose new diamonds in the
segments. If continual dressing is required, it would
indicate that the blade matrix composition is too hard
for the material being sawed.
b) Worn machine components. Determine that
machine components, including bearings, belts and
the arbor shaft are not excessively worn and
requiring replacement. Determine that the engine
runs smoothly to prevent harmonic vibrations which
can result in the blade impacting the work surface
with impulse type loads.
c) Failure to initially break in a new blade on a
specific material being cut. Allow the blade to
sharpen itself on the material to be sawed when first
placing it on the Crack Saw. This is the proper
method to break in a new blade. Do not force the
new blade into a cut as this will generally aggravate
the problem.
c) Saw head is misaligned. Periodically check saw
head for squareness in both vertical and horizontal
planes.
d) Loss of power, resulting from improper engine
RPM speed, electric motor voltage or loose V-belts.
See Service section.
SEGMENT CRACKS
a) Blade matrix composition is too hard for the
material being sawed. Utilize a blade with a softer
matrix composition.
e) When dry sawing, the blade becomes dull as a
result of overheating, allowing the segment rim to
"mushroom" or melt. Discontinue usage and contact
the diamond blade manufacturer.
SHORT BLADE SERVICE LIFE
a) Utilizing the improper blade for sawing a specific
material. Avoid the use of a general purpose blade
for sawing a single specific material. General
purpose blades are intended to saw a wide range of
materials. Since it is unlikely that the machine will
saw the proper amount of both hard and soft
materials proportionately at all times, this type of
blade is not the most economical method of sawing.
Use a blade with the matrix composition designed
specifically for the material and aggregate being
sawed.
BLADE BLANK WARPAGE
a) The blade blank has been overheated. While wet
sawing, improper water flow is being delivered to
both sides of the blade. Determine that all water
hoses are clean and free of any internal blockage.
b) The blade blank has been overheated. While dry
sawing, periodically allow the blade to run out of the
cut for up to 20 seconds for every minute sawing.
This procedure will allow the blade to cool in a few
seconds and allow the sawing process to proceed. If
the blade has been warped (dark blue color), it may
be damaged beyond repair. A blade in this condition
should be discontinued from use immediately and
properly discarded.
b) While wet sawing, improper water flow is being
delivered to both sides of the blade. Determine that
all water hoses are clean and free of any internal
blockage. Approximately two to five gallons of water
per minute are required to properly cool a blade.
c) Worn machine components. Determine that
machine components including bearings, belts and
the arbor shaft are not excessively worn and
requiring replacement. Determine that the engine
runs smoothly to prevent harmonic vibrations which
can result in the blade impacting the work surface
with impulse type loads.
c) The blade blank has been overheated as a result
of spinning on the arbor shaft. Check the arbor shaft,
hub body and hub flange for excessive wear and/or
damage. Properly tighten the arbor shaft nut.
d) Unequal flange clamping forces. The hub body
flange and hub flange must be of the same, identical
diameter. Always replace any questionable
component with a factory replacement part only.
d) Loss of power, resulting from improper engine
RPM speed, electric motor voltage or loose V-belts.
See Service section.

c) Blade is spinning on the arbor shaft. Check the
arbor shaft, hub body and hub flange for excessive
wear and/or damage. Worn, bent or dirty hub body
flange and hub flange will not allow the blade to be
properly tightened on the arbor shaft. Properly
tighten the arbor shaft nut. Replace any
questionable component with a factory replacement

BLADE WOBBLES
a) Worn machine components. Determine that
machine components including bearings, belts and
the arbor shaft are not excessively worn and
requiring replacement. Determine that the engine
runs smoothly to prevent harmonic vibrations which
can result in the blade impacting the work surface
with impulse type loads. Inspect the hub body flange
and hub flange for material accumulations. Keep all
surfaces clean and flat. Always replace any
questionable component with a factory replacement
part only.
d) Blade matrix composition is too hard for the
material being sawed. Utilize a blade with a softer
matrix composition.
e) Blade is not properly mounted to the Crack Saw.
Determine that the blade is mounted to the proper
diameter spindle before tightening the arbor shaft
nut. Never depend on the drive pin of the arbor hub
to actually drive the blade. The drive pin is simply a
safety device to prevent the blade from spinning on
the arbor shaft should the nut become loose.
b) Improper blade operating speed. Determine that
the blade is being operated within the industry
recommended RPM speed range. Engine RPM
should be checked periodically with an electronic
tachometer to ensure proper operational speed for
the blade.
c) Blade is bent. Contact the blade manufacturer. A
blade in this condition should be discontinued from
