WARNING WARNING
SILICOSIS WARNING
RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

Check the following on the blade guard (Figure 3):
2. Check uniform parallelism (Figure 5) of V-belt and
pulley (sheaves). Use a straight-edge or machinist's
square against both pulleys and adjust both pulleys
until equally aligned.
„ Ensure the capacity of the blade guard matches the
diameter of your diamond blade.
„ Check that the guard is bolted firmly upon the saw frame.
„ Check that the spring tensioned front cover of the guard
is firmly seated with the rear section of the guard and
there are no gaps. NeVer lift the blade guard while
cutting.
Ensure the v-belt cover is in place and securely fastened
during operation of the saw (Figure 4).
V-Belt Check
AwornordamagedV-beltcanadverselyaffecttheperformance
of the saw. If a V-belt is defective or worn, replace all the
V-belts.V-belts should always be replaced in sets.
Figure 5. Pulley Alignment
CauTioN
3. CheckV-belt tension by using a tension meter (3.0 lbs.)
against the inside belt at a mid point between the two
pulleys, or by deflecting the center belt at a mid point
3/16" (5 mm).
NeVer attempt to check theV-belt with the
engine running. Severe injury can occur.
Keep fingers, hands, hair, and clothing
away from all moving parts.
4. Do NoT over or under tighten the V-belt. Severe
damage can occur to the saw and engine crankshaft
if the belt is over-tensioned. A decrease of power to
the blade and poor performance will result if the belt
is under-tensioned (loose on pulleys).
V-belt Alignment andTensioning
This saw is equipped with a premium V-belt that has been
aligned and tensioned by factory personnel.TheV-belt must
be aligned and tensioned for proper operation of the saw.

blaDeS
Saw blades, or cutting disks, are available in either an
abrasive design or as diamond blades. Either blade will
work on the SP1E16A, however, diamond blades are
recommended.Ask your dealer about your specific cutting
application.
3. edge of The Steel Core — Check the diameter
edge for discoloration (blue oxidation) indicating an
overheating condition caused by insufficient cooling
water/air. Overheating of blades may lead to loss of
core tension and/or increase the possibility for blade
failure. Check to make sure the steel core’s width is
uniform about the rim of the blade, and not succumbing
to an “under cutting” condition brought about by highly
abrasive material or improper under cutting core
protection.
WarNiNg
Failure to thoroughly inspect the diamond
blade for operational safety could result in
damage to the blades or the saw and may
cause injury to the user or others in the
operating area.
4. Directional arrow — Check to ensure that the blade is
oriented properly on the spindle for sawing.Reference
the directional arrow on the blade and place it so the
direction of rotation “downcuts” with the turn of the
shaft.
Figure 6 highlights the components of a diamond blade.
5. Diamond Segment or rim — Ensure there are no
cracks, dings, or missing portions of the diamond
segment/rim. Do NoT use a blade that is missing
a segment or a portion of the rim. Damaged and/
or missing segments/rims may cause damage to your
saw, and injury to the user or others in the operating
area.
6. Specifications — Ensure that the blade specifications,
size, and diameter properly match up to the sawing
operation. Wet blades must have water to act as a
coolant.Utilizing a diamond blade not matched properly
to the task may result in poor performance and/or blade
damage.
7. arbor Hole — It is essential that the arbor hole
diameter properly matches the shaft arbor (1"), and
that it is free from distortions. Correct blade flanges
(collars) must be used. The inside face of the flanges
must be clean & free of debris. An out of round arbor
condition will cause damage to the blade and the saw.
Figure 6. Diamond Blade
1. Drive pin Hole — A commonly located hole on the
diamond blade core that prevents operational blade
slippage between the inner & outer blade flanges
(collars). Inspect the diameter of the hole to ensure
there is no distortion, and that a snug fit develops
between the hole and drive pin.
8. MaX rpM — This RPM reference is the maximum
safe operating speed for the blade selected. NeVer
exceed the max RPM on the diamond blade.Exceeding
the MAX RPM is dangerous, and may cause poor
performance and may damage the blade. All blades
used must be designed for the maximum spindle
RPM.
2. Stress relief Holes (gullets) — Check the steel core
for cracks that may have propagated from the slots

1. Blade guard — Pivot the blade guard front cover all
the way back. The guard tension spring will keep the
front cover in position.
alWayS ensure that unit is unplugged (disconnected)
when installing blade.
2. Blade Hex Nut — Unscrew the blade shaft nut (right
side loosens clockwise and tightens counter-clockwise
while the left side loosens counter-clockwise and
tightens clockwise. DO NOT overtighten the nut
(approximately 45-50 ft. lb/61-68 N/m) when finalizing
the assembly.
1. Set the motor ON/OFF switches to
the oFF position to prevent accidental
starting.
2. Place the saw on a stable level working
surface.
3. outside Blade Flange (Collar) — Ensure that the
outside blade flange is placed flush against the
diamond blade.The inside surface of the flange must be
free of debris and permit a tight closure on the surface
of the blade core.
3. Ensure the blade is raised and the raise/lower crank
is locked into position.
NOTICE
When removing or installing a diamond blade, please
note that the blade retaining nuts are left and right-hand
threaded.
4. Diamond Blade — Ensure that the proper diamond
blade has been selected for the job.Pay close attention
to the directional arrows on the blade. The blade's
operating directional arrows must point in a "down-
cutting" direction to perform correctly. When placing
the blade onto the blade shaft, ensure the arbor hole
of the blade matches the diameter of the shaft.
4. Lift up the blade guard cover to gain access to the
blade.
5. inner Flange (Collar) — This flange is fixed upon the
blade shaft. The inside surface of the flange must be
free of debris and permit a tight closure on the surface
of the blade.
BlaDe SpeeD
A diamond blade’s performance is directly connected to
specific peripheral (rim) speeds.
Figure 7. Mounting the Diamond Blade
The following shaft rotational speeds have been factory set
to ensure optimum blade performance.
5. Use the provided blade nut wrench to remove and
install the blade (Figure 7).

6. Unscrew the spindle nut (right side loosens clockwise
and tightens counter-clockwise while the left side
loosens counter-clockwise and tightens clockwise).
Do NoT overtighten the nut (approximately 45-50 ft.
lb/61-68 N/m) when finalizing the assembly.
NOTICE
The following steps should be accomplished before
using the saw on any cutting surface.

See"BladeRemovalandReplacement"sectioninthismanual.
1. To begin sawing, lower the rotating blade allowing it to
cut to the preset depth.
Front pointer adjustment
2. When the blade has reached full cutting depth, slowly
walk behind the saw at a rate that will allow the motor
to operate without losing optimum RPM.
CauTioN
alWayS ensure that unit is unplugged (disconnected)
when installing blade.
CauTioN
The front pointer wheel has been set at the factory. Use
these procedures only if the pointer is suspect of being
out of alignment.
Do NoT try to cut faster than the blade will allow.
Cutting too fast will cause the blade to rise up out of
the cut. Improper cutting rate can decrease the life of
the motor and blades.
1. Chalk out a straight line on the prepared slab or cutting
surface.
2. Use a 4 foot straight-edge or level by placing it flat
against the blade.
NOTICE
Mark the cutting line clearly.oNly saw in a straight line.
3. Adjust the front pointer wheel so it just touches the side
of the straight-edge or level.
3. When the end of the cut has been reached, raise the
blade out of the cut by pulling back on the handlebars
(using a downward pressure) until the raise/lower rod
drops into its slots with the blade in the raised position.
4. Remove the straight-edge or level.
5. Position the front pointer and blade directly over the
chalk line.
4. If cutting is complete, turn the motor off and wait for
the blade to stop rotating.
6. Start the saw and lower the blade onto the chalk line.
7. Begin cutting and make sure the blade follows the chalk
line as closely as possible.
SToppiNgTHe SaW
1. Place the electric motor’s ON/OFF switch in the OFF
position.
8. The pointer should follow the chalk line as well.If it does
not, adjust the pointer by loosening then tightening the
jam nuts on the pointer until the pointer follows the
same path as the blade.
2. Disconnect the electric motor’s extension cord from
its power source.

Chassis lubrication
„ Blade Shaft Bearings — Two zerk fittings are located
at the lower-front area of the saw. Lubricate before daily
use. Use a good quality automotive or general purpose
grease. Check and lubricate more often if unit is under
heavy use. Do not overfill bearings. Overfilling can
damage the grease seals which can result in bearing
exposure to dirt and contaminants which can then
shorten the life of the bearings. Excess grease can also
drip onto the cutting surface.
