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 areas approved, and away from sparks or flames. Don
not fill the saw 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 guard 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 orderless,
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 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 BARS

5
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.

2. The blade collars and arbors should be cleaned and examined for
damage before mounting the blade.
3. The blade must be properly fitted over the arbor with the drive pin on
the outside collar projecting through the drive pin hole on the blade
and inside collar.
4. The blade shaft nut, which is a left hand thread nut, must be tightened
securely against the outside blade shaft collar.
5. The blade must be operated within the specified maximum operating
speed listed on the blade.
6. Turn water control valve to full to provide adequate coolant (5 to 8
gallons per minute) for diamond blades and wet cutting abrasive
blades. Insufficient coolant could result in severe blade breakage or
diamond segment separation.
7. The blade guard must be in place with the nose guard down and locked
when the saw is running.
8. The operator should wear safety glasses and any other appropriate
safety equipment.
9. When starting the saw, the operator should stand away and to the side
of the blade.
10.If for any reason the saw should stall in the cut, raise the blade out of
the cut. Check the outside blade shaft collar and nut for tightness.
Inspect the blade for damage before restarting the saw. User caution
when resuming a cut. Be certain that the blade is in alignment with the
previous cut.
11.During cutting operations, do not exert excess side pressure on the
handles as a method of steering. Do not force the blade into the cut by
lowering the blade too fast or by pushing the saw too fast.
You Are Responsible For Your Safety!!!

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 proper 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”
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.
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.

D. 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.

10. 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!
11. For Self-propelled models move the Transmission Engage/Disengage lever
fully to the engage position and then slowly push the Speed Control forward
until the desired speed is reached. If the engine begins to stall or the saw
raises out of the cut slow the forward speed down! The further the lever is
pushed the fast the saw will move.
12. 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.
13. To place the machine in reverse: move the Speed Control lever towards the
back of the machine. Only move the saw in reverse with the blade in the
raise position. Always place the speed control back in the neutral position
after moving the saw.
14. 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.

20
15. To disengage the transmission, place the Speed Control in the Neutral
position and then slide the Transmission Engage/Disengage lever fully to
the “Disengage” position.
Caution: Do Not Engage Or Disengage The
Transmission While The Machine Is In The
Forward Or Reverse Positions!
G. 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.
Additional Guide Lines For Sawing:
Understand and follow all of the instruction in this owner’s manual.
If wet cutting, turn on the water supply so that there is a minimum of two
gallons per minute of water flow!
In critically hard aggregate more than a single pass may be needed to cut
the desired depth.
Only move the Engage/Disengage lever while the transmission speed control
is in the neutral position.
Move the transmission speed control slowly.
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.
