SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metaland
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.
WARNING
Grinding/cutting/drilling of masonry, concrete, metaland
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 beingused.

SP2S13H20A SAW — OPERATION AND PARTS MANUAL — REV. #1 (05/17/10) — PAGE 15
GENERAL INFORMATION
Familiarization
The SP2S13H20A saw is designed for
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.
Heavy-duty front and rear axles, sturdy oversized wheels and
industrial undercarriage assembly ensures accurate tracking and
years of reliable use.
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.
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.
The SP2S13H20A saw uses a
gasoline engine
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 three V-belts. As the engine shaft
rotates, so does the blade.
Refer to the engines Owner's Manual for the specific instructions
regarding engine operation and maintenance practices.
Console

Water System
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
The 20-inch blade guard is designed with two 6-inch vinyl water
tubes to direct water to the diamond blade.
Under Carriage System
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.
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.
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 combination of pulley and blade shaft bearing positioning
ensures minimal vibration & flutter to the ends of the blade shaft.
Water System
The SP2S13H20A saw comes standard with a 20-inch hinged

Hydrostatic Transmission
An EATON® Model 7 hydrostatic transmission (Figure 8)
provides the power for the saw's propulsion system. The
transmission drives a sprocket that directly connects the spline
drive to the rear wheels. The no load forward/reverse speeds
are approximately 80 ft/min.
Figure 8. Hydrostatic Transmission
The transmission is factory filled with approved hydraulic fluid
that has a viscosity equivalent to SAE 20W-20. Should additional
servicing be required, the following hydraulic fluids are
recommended:
General Motors Dextron B
Ford MM2C-33F
Ford M2C-41A
International harvester Hy-Tran Fluids
Battery - The 12-volt DC battery (Figure 10) is shipped dry,
and will require a proper electrolyte level for operation.
When servicing of the battery is required perform the following:
A face shield and rubber gloves should be worn while
handling and servicing battery's electrolyte.
Disconnect battery terminal clamps, and remove the battery
from the saw when servicing is required.
DO NOT overfill the battery.
Electrolyte is an acid and must be handled
with caution. Servicing instructions from the

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.
Check the steel core for
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.
