SILICOSIS/RESPIRATORY WARNINGS  
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.

GENERAL INFORMATION  
Familiarization  
Water System  
The SP2S13H20A saw is designed for wet or dry cutting of  
concrete or asphalt utilizing diamond blades.They have been  
engineered for general, industrial and high production flat cutting  
applications.The reinforced steel box frame design adds strength  
necessary to reduce vibrations while cutting. Minimizing  
vibrations enhances the performance of the blade and extends  
the life of the saw.  
All saws provide a water direction system to provide cooling  
water to the diamond blade.This system consists of:a standard  
"garden hose" valve that connects to the water source (via hose)  
to the saw, an ON/OFF console water valve'  
The 20-inch blade guard is designed with two 6-inch vinyl water  
tubes to direct water to the diamond blade.  
Under Carriage System  
Heavy-duty front and rear axles, sturdy oversized wheels and  
industrial undercarriage assembly ensures accurate tracking and  
years of reliable use.  
A jig welded heavy steel gauge under carriage assembly  
supports the saw in tracking, pivoting and stabilization. A rear  
axle supports two solid rubber cast hub wheels with roller  
bearings, grease fittings and locking collars.A front axle supports  
two solid rubber cast hub wheels with roller bearings, grease  
fittings and locking collars.The assembly pivots about two rocker  
blocks with bushings.  
Additionally, the general weight-to-strength ration design of the  
frame and chassis assembly provides optimum weight  
distribution to keep the blade running true in the cut. A rugged  
blade shaft bearing assembly ensures minimal flutter and shaft  
harmonics providing the most advantageous condition for a  
diamond blade at operating speeds.  
Blade Drive System  
A rugged blade shaft assembly has been specifically designed  
to support the optimum distribution of torque from the engine  
shaft to the blade shaft, and to ensure minimal vibratory conditions  
on the tips of the shaft.  
Power Plants  
The SP2S13H20A saw is generally classified in the industry as  
LOW to MEDIUM horsepower saws. This classification is  
particularly useful when selecting the proper diamond blade for  
an application.  
Balanced engine & blade shaft pulleys are connected to their  
respective shafts, 3 V-belts (13HP, 4 V-belts for 20HP models)  
connect to the engine pulley to the blade shaft pulley.The blade  
shaft is supported by two self-aligning pillow block bearings that  
are uniquely positioned on the most outboard portion of the  
reinforced frame.  
The SP2S13H20A saw uses a 13 HP Honda GX390K1QWT2  
gasoline engine air-cooled, 4-stroke single cylinder, OVH rated  
at 3600 RPM.Blade rotation is v-belt driven.This is accomplished  
by connecting to the output shaft of the engine to an upper drive  
pulley.The lower drive pulley (Blade) is then connected to the  
upper drive pulley (Engine) by threeV-belts.As the engine shaft  
rotates, so does the blade.  
The combination of pulley and blade shaft bearing positioning  
ensures minimal vibration & flutter to the ends of the blade shaft.  
Water System  
Refer to the engines Owner's Manual for the specific instructions  
regarding engine operation and maintenance practices.  
The SP2S13H20A saw comes standard with a 20-inch hinged  
two piece, heavy steel gauge blade guard. The blade guard  
provides access for vinyl water tubes that supply optimum volume  
and dispersal of water for cooling and/or dust suppression.  
Console  
An ergonomically designed control console allows the operator  
to easily understand and/or operate the adjustable handlebars,  
Raise/Lower Crank Handle, and transmission engage/  
disengage lever.Additionally, the console also provides forward/  
reverse controls.  
Manual Raise/Lower System  
The SP2S13H20A saw uses an ACME thread, manual raise/  
lower assembly easily raises and lowers the blade and can lock  
into position to ensure a constant depth when cutting.SeeTable  
6 for blade selection with respect to depth of cut.  
The SP2S13H20A saw is  
designed, engineered and  
manufactured with strict  
adherence to American National  
Standards Institute, Inc. (ANSI)  
guidelines B7.1 and B7.5

INSPECTION -BLADE  
4.  
Directional Arrow – Check to ensure that the blade is  
oriented properly on the blade shaft for sawing. Reference  
the directional arrow in the blade and place it so the direction  
of rotation “downcuts” with the turn of the shaft.  
WARNING  
Failure to thoroughly inspect the diamond blade (Figure 11)  
for operational safety could result in damage to the blade,  
the saw, and may cause injury to the user or others in the  
operating area.  
D
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 blade, 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.  
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.  
Figure 11. 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.  
2.  
Stress Relief Holes (Gullets) – Check the steel core for  
cracks that may have propagated from the slots and/or  
gullets. Cracks indicate extreme fatigue failure and if sawing  
continues, catastrophic failure will occur.  
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.

Adjusting the Blade Height  
CAUTION  
NEVER stop the engine while cutting at high speeds, except for  
extreme emergencies. This can damage your SP2S13H20A  
Saw.  
The SP2S13H20A saw uses a manual raise/lower crank  
handle located on the console with clockwise rotation providing  
lowering action, and counter-clockwise rotation providing  
raising and lowering action (Figure 37).  
To adjust the blade height:  
Adjusting the Handle Bars  
1. Pull upward on the raise/lower crank handle knob.  
The SP2S13H20A has adjustable height handle bars. Before  
operating the saw, adjust the handle bar height to a comfortable  
working position:  
2. Rotate the crank handle clockwise to lower the blade.  
Rotate the crank handle counter-clockwise to raise the  
blade (Figure 37).The handle will stop rotating when the  
blade has been fully raised or lowered.  
1. Loosen the height adjustment bolts (Figure 35) on the handle  
bars until the handle bars can freely pivot.

2. Lift the transmission engage/disengage lever,  
located on the console (Figure 39). Leaving the lever down  
disengages the transmission to allow for manual pushing  
during cutting or moving the machine around the job site.  
Saw Alignment  
1. The SP2S13H20A saw employs a front pointer (Figure 42)  
that has been precisely aligned with the diamond blade at the  
factory. Referencing the figure below, accurate tracking is  
accomplished by referencing the front pointer tip over the cut  
line. Precise saw direction is accomplished by slight operator  
pressure against the handle bars.

MAINTENANCE  
Maintenance  
Engine air filter:  
Clean air filter 2 to 3 times daily when DRY cutting. See  
WARNING  
Engine Owner’s Manual for detailed information.  
Engine tank & strainer:  
General maintenance practices are crucial to the  
performance and longevity of your saw. The extreme  
environments of sawing operations require routine  
cleaning, lubrication, belt tensioning, and inspection for  
wear and damage  
Clean every year/or 300 hours.  
Fuel line:  
Replace every two years/or as necessary.  
Spark plug:  
The following procedures devoted to main-  
tenance can prevent serious saw damage  
or malfunctioning. Before servicing or in-  
spection, ALWAYS park the saw on a level  
surface with the blade removed, and the  
Console Engine ON/OFF switch & Engine  
ON/OFF switch in “OFF” position.  
Clean/adjust every 6 months/or 100 hours. Replace every  
year/ or 300 hours.  
Bearing Lubrication Care  
There are four grease points for the SP2S13H20A saw. [Use  
only Premium Lithium 12 based Grease, conforming to NLG1  
Grade #2 consistency.]  
Some maintenance operations may re-  
quire the engine to be run. Ensure that  
the maintenance area is well ventilated.  
Exhaust contains poisonous carbon mon-  
oxide gas that can cause of unconscious-  
ness and may result in DEATH.  
RearWheels (1):  
Grease daily, see Undercarriage Assy., item 10  
Blade Shaft Bearings (2):  
Grease daily, see Blade Shaft Assy., item 15  
Raise/Lower AdjustTube (1):  
Grease daily, see Raise/Lower Assy., item 2  
General Cleanliness  
Clean the machine daily. Remove all dust and slurry build up.If  
the saw is steam cleaned, ensure that lubrication is accomplished  
AFTER steam cleaning operations.  
When cutting DRY, lubricate blade  
shaft bearings 2 to 3 times daily.  
The grease can provide an added  
protective seal for the bearings.  
NOTE  
General Engine Care  
Engine check:  
Check daily for any oil and/or fuel leakage, thread nut & bolt  
tightness, and overall cleanliness.  
Engine oil:  
Check daily. Inspect with blade removed and saw frame  
level on a level surface. Keep the oil clean, and at the proper  
servicing level (Figure 8). DO NOT OVERFILL! SAE 10W-  
30 of SG is recommended for general use.  
Engine oil change:  
Change engine oil the first month or 20 hours of operation.  
Then every 3 months/or 50 HOURS of operation. See Engine  
Owner’s Manual for detailed information.  
ALWAYS dispose of used oil in a  
responsible manner. Ensure that  
the disposition of all hazardous  
NOTE  
waste is handled properly. Call  
your Recycling Center for  
information about recycling engine  
oil.

MAINTENANCE  
GeneralTransmission Care  
Spline GearWheels:  
All SP2S13H20A model saws utilize spline gear wheel design  
coupled with an EATON Model 7 HydrostaticTransmission that  
provides forward/reverse propulsion. The simple design of the  
system keeps maintenance to a minimum.  
Check every 25 hours and clean as necessary. If the spline  
wheels DO NOT engage the rear wheels with sufficient  
pressure, slippage of the rear wheels may occur.  
To adjust the Spline Gear Assembly:

MAINTENANCE  
Battery Maintenance  
Check the battery regularly and make sure that each  
electrolyte level is to the bottom of the vent well  
(Figure 43). If necessary add only distilled water in a  
well-ventilated area.  
Mishandling of the battery shortens the service life of the battery  
and adds to maintenance cost.When handling the battery do the  
following:  
Be careful not to let the battery electrolyte come in contact  
with your body or clothing.  
Always wear eye protection and rubber gloves, since  
the battery contains sulfuric acid which burns skin and eats  
through clothing.  
Always check the battery terminals periodically to  
ensure that they are in good condition.  
Use wire brush or sand paper to clean the battery  
terminals.  
Always check battery for cracks or any other damage.  
If white pattern appears inside the battery or paste  
has accumulated at the bottom, replace the battery.  
Figure 43. Battery Electrolyte Levels  
If the pump will not be in operation for a long period  
of time, store in cool dry place and check the battery  
charge level every month to maintain the performance  
of the battery.  
WARNING
