I. PREPARATION
A. Safety Precautions
Important! The following safety precautions must always be observed.
Hazard Symbols
Fuel (gasoline) is extremely flammable and its vapors can
explode if ignited. Store gasoline only in approved containers,
in well-ventilated, unoccupied approved areas, and away from
sparks or flames. Do not fill the fuel tank while the engine is hot
or running. Do not start the engine near spilled fuel. Never use
the fuel as a cleaning agent
Engine components can get extremely hot from operation. To
prevent burns, do not touch the engine or related parts while the
engine is running or immediately after it is turned off. Never
operate the engine with any heat shields or guards removed.
Keep all guards in place when operating any piece of equipment
Keep hands, feet, hair, and clothing away from all rotating parts
Lethal Exhaust Gas: use only in well ventilated areas. Engine
exhaust gases contain poisonous carbon monoxide, which is
odorless, colorless, and can cause death if inhaled. Avoid
inhaling exhaust fumes, and never run the engine in a closed
building or confined area.
Never tamper with the governor components of settings to
increase the maximum speed. Severe personal injury and
damage to the engine or equipment can result if operated at
speed above maximum. Always obey the maximum speed
rating of blade.
DO NOT LIFT THE SAW BY THE HANDLE

Dust and Silica Warning
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 and make certain to comply
with all product warnings and instructions for the safe and effective use of the
material being cut. 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
manufacturer/supplier, 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
through engineering controls such as vacuum and/or water mist, the operator
and any bystanders should always wear a respirator approved by NIOSH/MSHA
for the material being cut.

C. Engine Operation
Prior to attempting to operate the engine, read the information
contained in the engine owner's manual. An engine owner’s manual
is supplied with every gasoline powered concrete saw.
1. Check Oil: Add oil if low. Refer to the engine owner's manual for the
recommended SAE viscosity grades. Capacity of oil is 1.1 liters (1.16 US qt)
2. Check Fuel: Fill if low. Use only unleaded gasoline with a pump sticker
octane rating of 86 or higher is recommended. Never use an oil and
gasoline mixture!
3. Air Cleaner: Never run the engine without the air cleaner! Rapid engine
wear will result from contaminants being drawn through the carburetor and
into the engine.
4. Engine Starting: Refer to the engine owner's manual for detailed engine
starting procedure.
5. Engine Speed: Always run the engine and the proper speed for the blade
being used. Never run the blade at a higher speed that it is rated for. See
the Blade Speed chart located on the machine’s console or located in the
manual under the heading “Operating the Saw”
6. All 13 HP units are equipped with a Choke control attached to the Engine
below the Air Cleaner on the Operator’s Right Hand Side.
D. Starting the Engine
1. Refer to the engine owner's manual for detail starting procedures.
2. Always cut with engine rpm in the full throttle setting.

15
Before starting, insure that the blade is properly installed, all
guards are in place and in safe operating condition, and that the
Blade is not in contact with any surface or object. Also verify
that the area where the work is to be preformed is clean, safe,
and has proper ventilation and lighting. Always located and
properly mark all water, gas, and electrical services before
beginning any work.
Locate and under stand the functions of the: Engine Fuel Control Valve
(Located on the Engine under the Air Cleaner), Choke Control (Located On
the Engine under the Air Cleaner), ON/OFF Switch (located on the Operator’s
Left Side Top of the Console), and Throttle Control (located on the Operator’s
Left Side Top the Console). SEE Section F. Controls for Details on the
locations and operation of the machines controls before operating.
Turn the Fuel Control To the ON Position Move the choke lever to the CLOSED position.
NOTE: do not use the choke if the engine is
warm or the air temperature is high.

Pull the starter grip lightly until you feel resistance,
then pull briskly. CAUTION: Do not allow the starter
grip to snap back against the engine. Return it gently
to prevent damage to the starter.
As the engine warms up, gradually move the choke
lever to the OPEN position. Position the throttle
control lever for the maximum engine speed (full
Rear).
To stop the engine, move the Throttle Control Lever fully to the Rear Position
(Slow) right, then turn the engine switch to the OFF position. Turn the fuel
valve to the OFF position.
Never transport the machine with the Fuel Valve in the ON
position. Never Store the machine with the Fuel Valve in the
ON position. Never Transport a machine with the blade
installed.
E. Water Supply
Pressurized source: Turn the water control to full "ON" when using wet
cutting blades. The required flow rate is 4-6 gallons per minute.
Optional Water Tank on saw: This supply is designed for use with dry
blades to keep the dust levels down. The tank will not supply the proper
water flow rates when used with wet cut only blades. Do not drink the
water from this tank. Fill the tank with water only. Close the water tank
valve. Attach the saws water supply hose to the tank outlet. Fill the tank
with water. The capacity of the tank is 5 US Gallons. When you are ready
to cut, adjust the water supply rate until a fine mist or a slow trickle is
made. The use of water greatly decreases the amount of dust produced
during the cutting process, aids in the cooling of the blade, and provides
additional stability.
Use Only Water In The Water Tank
Do Not Drink From The Tank

11. Slowly lower the blade by rotating the hand wheel clockwise until the
desired depth of cut is reached. Use a reasonable rate of feed. A
reasonable rate of feed will depend on depth of cut, material, and blade.
Normal cutting speeds should be between 2 ft/min in very hard material
and up to 10 ft/min in softer materials. Do not force the blade in to the
cut! If the engine begins to stall or the saw raises out of the cut slow the
forward speed down!
12. If the engine begins to stall or the saw raises out of the cut slow the
forward speed down!
13. When moving the saw to a new location, be sure the blade is not
touching the ground. Always pay close attention to where you are
moving and where the blade is at all times.
13. When the end of the cut is reached, slowly raise the blade out of the cut
by rotating the Hand Wheel Clockwise until the blade is at least one (1)
inch above the ground.
14. To move the machine in reverse raise the blade out of the cut and pull
back on the machine. Only move the saw in reverse with the blade in the
raise position.
15. When moving the saw to a new location be sure that the blade is not
touching the ground and always pay close attention to where you are
moving and where the blade is at all times.
Caution: Do Pull The Machine Backwards While The
Blade Is In The Cut As The Blade May Be Damaged.
H. Cutting Technique
Lower the blade into the concrete to the required depth by turning the hand
wheel clockwise. Ease the handle slowly forward. Retard the forward
pressure if the saw begins to stall. Note: For deeper cuts (4 inches or more),
several cuts should be made in incremental steps of 1-1/2 to 2 inches until the
desired depth of cut is reached. Push the saw steadily forward using the front
pointer as a guide. Exert enough forward pressure so that the engine begins
to labor, but does not slow down. If the saw begins to stall, retard the forward
movement until full rpm is restored to the blade. If the saw stalls, raise the
blade out of the cut before restarting. Avoid excessive side pressure or
twisting of the blade in the cut.

20
Additional Guide Lines For Sawing:
Understand and follow all of the instructions in this owner’s manual.
If wet cutting, turn on the water supply so that there is a minimum of 4-6
gallons per minute of water flow!!
In critically hard aggregate, more than a single pass may be needed to cut
the desired depth.
If the saw stalls in the cut, immediately stop the forward speed and raise
the blade out of the cut. If this is not done the belts can fail or the blade
may be damaged.
Go slowly with a new blade until it opens up, that is, until the diamonds
can be seen and felt.
I. Lead-Off Adjustment
If the saw tends to pull to one side (lead off), it may be steered by applying
slight pressure to the left or right hand handles.
