HAZARD SYMBOLS

SAFETY MESSAGE ALERT SYMBOLS

The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,

WARNING, or CAUTION.

Lethal Exhaust Gases

Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and

odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined

area or enclosed structure that does not
provide ample free flow air.

Explosive Fuel

Gasoline is extremely flammable, and its
vapors can cause an explosion if ignited.
DO NOT start the engine near spilled fuel or
combustible fluids. DO NOT fill the fuel tank
while the engine is running or hot. DO NOT
overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or
sparks from the ignition system. Store fuel in

approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.

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.

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.

Ensure that the blade is mounted for proper operating
direction.

STOW CUTTER 3 CE SAW — GENERAL INFORMATION

Familiarization

The Cutter 3 saws are designed for
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 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.

There are two gasoline engines used with the Cutter 3 saws: A

13 HP Honda GX390K1QWT2

cylinder, OVH rated at 3600 RPM and a

GX620TXF2

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.

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 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.

1. Read and fully understand this manual,
the safety intructions in particular, and
the engine manufacturer's manual
supplied with the saw.

2. Select the correct blade for each application. Refer to the
Blades and Blade Placement sections on pages 17 through

3. Check blade for wear or damage.
Handle all blades with care and
ALWAYS replace a damaged blade.

4. Clean the saw, removing dirt and dust,
particularly the engine cooling air inlet,
carburetor and air cleaner.

5. Check the air filter for dirt and dust. Replace the air filter if it
is found to be dirty.

6. Check carburetor for external dirt and dust. Clean with dry
compressed air.

7. Check fastening nuts and bolts for tightness.

8. Ensure a suitable water supply is available, hooked up, and
used. (connected via garden hose or with a water tank supply
system).

The Engine Stop Switch located on
the handlebar (Figure 23) serves
both as an Emergency Engine

Shut-Off and as the primary
Shutdown switch. This allows the

operator to shutdown the saw safely
away from moving parts.

After shutdown on Electric Start
models, ensure the Engine Start
switch is turned to the OFF position
to avoid battery discharge and
accidental starting.

4. Ensure the water tank is filled to capacity (18.95 liters/5
gallons). Connect the water tank hose to the water system
brass fitting on the rear of the console (Figure 18) and test for
adequate water flow to the diamond blade before operation.

When ready to start cutting, turn the water on.
