STOW CUTTER 3 CE SAW — RULES FOR SAFE OPERATION  
Diamond Blade Safety  
General Safety  
Use appropriate steel centered diamond blades  
manufactured for use on slab saws.  
ALWAYS read, understand, and follow procedures in  
Operator's Manual before attempting to operate equipment.  
Examine blade flanges for damage and excessive wear.  
ALWAYS be sure the operator is familiar with proper safety  
precautions and operating techniques before using the saw.  
Ensure the cleanliness of the blade before blade is installed.  
Blade should fit snugly on the shaft and against the inside/  
outside blade flanges.  
NEVER leave the machine unattended while running.  
Block the unit when leaving or when using on a slope.  
Ensure the blade is marked with an operating speed greater  
than the blade shaft speed of the saw.  
ALWAYS check to make sure that the operating area is  
clear before starting the engine.  
Maintain this equipment in a safe operating condition at all  
times.  
WARNING  
ALWAYS stop the engine before servicing, adding fuel and  
oil.  
ALWAYS inspect diamond blades  
before each use. The blade should  
exhibit no cracks, dings, or flaws in the  
steel centered core and/or rim. Center  
(arbor) hole must be undamaged and  
true.  
NEVER run the engine without the air filter. Severe engine  
damage could occur.  
ALWAYS service air cleaner frequently to prevent carburetor  
malfunction.  
AVOID wearing jewelry or loose fitting clothing that may  
snag on the controls or moving parts, this can cause a serious  
injury.  
WARNING  
Only cut the material that is specified for the diamond blade.  
Read the specifications of the diamond blade to ensure  
the proper tool has been matched to the material being cut.  
The saw has been engineered for WET CUTTING. Ensure  
a WET CUTTING blade is being used and that the water  
supply system to the blade is properly functioning and being  
used.  
ALWAYS keep clear of rotating or moving parts while  
the saw is in operation.  
ALWAYS store equipment properly when it is not being  
used. Equipment should be stored in a clean, dry location  
out of the reach of children.  
ALWAYS keep the work area well organized.  
ALWAYS clear the cutting area of any debris, tools, etc.that  
would constitute a hazard while the saw is in operation.  
ALWAYS keep blade guards in place. Exposure of the  
diamond blade must not exceed 180 degrees.  
Ensure that the diamond blade does not come into contact  
with the ground or surface during transportation. DO NOT  
drop the diamond blade on ground or surface.  
WARNING  
ALWAYS check to make sure that the  
operating area is clear before starting the  
engine.  
The engine governor is designed to permit maximum engine  
speed in a no-load condition. Speeds that exceed this limit  
may cause the diamond blade to exceed the maximum safe  
allowable speed.  
No one other than the operator is to be in the working area  
when the saw is in operation.  
Ensure that the blade is mounted for proper operating  
direction.  
Always observe all applicable compulsory regulations  
relevant to environmental protection, especially, fuel storage,  
the handling of hazardous substances, and the wearing of  
protective clothing and equipment. Instruct the user as  
necessary, or, as the user, request this information and  
training.  
Adhere to the Blade Manufacturer's recommendations on  
handling, storage, and safe usage of blades.

STOW CUTTER 3 CE SAW — GENERAL INFORMATION  
Familiarization  
Water System  
The Cutter 3 saws are 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 Cutter 3 saws are 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.  
There are two gasoline engines used with the Cutter 3 saws: A  
13 HP Honda GX390K1QWT2 air-cooled, 4-stroke single  
cylinder, OVH rated at 3600 RPM and a 20HP Honda  
GX620TXF2 air-cooled, 4-stroke OVH 90°V-twin 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  
The Stow Cutter 3 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.  
Refer to the engines Owner's Manual for the specific instructions  
regarding engine operation and maintenance practices.  
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 (Self-propelled models only).Additionally, for  
self-propelled models, the console also provides forward/reverse  
controls.  
All Stow Cutter 3 saws are  
designed, engineered and  
manufactured with strict  
adherence to American National  
Standards Institute, Inc. (ANSI)  
guidelines B7.1 and B7.5  
Manual Raise/Lower System  
NOTE  
The Cutter 3 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 7 for  
blade selection with respect to depth of cut.
