Read and understand this Operator’s Instruction Manual,
and the Engine Manufacturer’s Owner’s Manual
before operating this equipment.
Death of serious injury can result if this machine is used improperly.
Safety Guidelines
Eye and ear protection must be worn at all times while the saw is in use. During normal
operation, sound pressure levels exceed 92dBA. Use only ANSI approved safety glasses to
help prevent eye injury . S tandard eyeglasses have only impact resistant lenses; they are NOT
safety glasses.
Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry that
can get tangled in moving parts. Footwear should provide sure footing and protection from debris
that may be dropped. Take step s to insure hair will not be caught in moving part s. If necessary ,
tie it back.
•When loading or unloading the saw, use caution. Make sure rolling t able is locked so that the blade will not be
damaged. Do not move the saw while the engine is running.
•Never exceed the maximum operating speed of the blade. Match the blade speed rating with the arbor shaft speed.
(See page 1 1)
•Never leave the saw running unattended.
•Never operate this saw under the influence of drugs, alcohol or when taking medications that impair the senses or
reactions, or when excessively tired or under stress.
•Do not lend or rent this equipment without including the Operator’s Instruction Manual and the Engine Manufacturer’s
Manual.
•Make sure all safety decals can be clearly read and understood. Replace damaged or missing decals immediately .
For Electric Models:
•Electric motor must be properly grounded at all times. Check the outlet box to be sure the electrical service is
properly grounded and that adequate power is available. Insufficient power will cause motor to overheat and burn out.
Use only grounded extension cords correctly sized for the current draw and voltage drop (amp rating and length).
Never use frayed, damaged, taped or underrated extension cords. Electrical shock could result in death or serious
injury and damage to the equipment.
For Gasoline Models:
•Poisonous exhaust gas. Do not operate gasoline powered equipment without adequate ventilation. Carbon monoxide is an invisible, odorless gas that can kill. NEVER REFUEL AN ENGINE WHILE IT IS HOT OR AN ENGINE
WHILE IT IS RUNNING . Only refuel in a well-ventilated area and only refuel after the engine has cooled completely.
Thoroughly cleanup any spilled fuel before starting the engine.
Dry cutting creates a large volume of airborne dust. For health reasons, the operator should wear
an applicable respirator. The dust may cont ain chemicals known to cause serious illnesses, including Silicosis - a fatal disease of the lungs. Check the chemical properties of the material to be cut
and follow all EPA/OSHA regulations.
Safety warnings and guidelines do not by themselves eliminate danger.
They are not substitutes for proper accident prevention procedures and good judgement.

On Gasoline Models:
•Gasoline models are shipped from the factory dry , meaning without oil or gasoline.
Both will need to be added before the unit is used. Check the Engine Manufacturer’sOwner’s Manual for instructions on break-in, servicing and proper use of engine.
•Check engine oil. Make sure that it is at the proper level and that it is clean.
Note: Some engines have an Oil Alert System that will automatically stop the engine before the oil level falls below
the safe limit. T o avoid an unexpected shut down, check the oil level regularly during operation.
•Check the fuel level. Do not over fill fuel tank and never refuel a hot engine. If refueling is necessary during operation,
allow engine to cool down first.
Figure 7
On Electric Models:
•Electric masonry saws are shipped with a twist lock, grounded, male plug attached to the machine and a female
mating connector which a qualified licensed electrician should attach to a user-supplied extension cord. V erify
that the extension cord is sized appropriately for the electrical load and that it is properly grounded.
Use only 3 wire (single phase), 4 wire (three phase) grounded electrical
cables that are marked U.L. and/or C.S.A. approved.
•Inspect the power and extension cords for damage. Do not use if either cord is frayed or
showing signs of wear.
•Identify the electrical power requirements of the saw . The voltage requirement s of the
motor can be found on the motor data plate. For dual voltage models, be sure the voltage
selector switch position correctly matches the incoming power source and that it is
locked into the selected voltage position with the locking bolt. (Figure 8)
•V erify that the power switch is in the off position before plugging machine into the power

DO NOT LET THE
WA TER PUMP RUN DRY .
On All Models:
•The water in the tray must be kept clean. Running
dirty water through the system will cause damage.
•T o change the water , turn off the saw , remove the
plug in the bottom of the tray to drain water and
dispose of properly . Do not drain onto the surface
being worked on or other maintained surface because
staining will occur . Flush any loose grit and dirt out of
the tray . Replace drain plug and refill with clean
water. If water flow to the blade seems to be low,
check that strainer is clean and the water pump
pulley is properly engaged.
•Determine that the recoil starter assembly turns freely , starter rope pulls easily, and the rope retracts properly .
•Follow the instructions supplied in the Engine Manufacturer’s Owner’s Manual for starting engine.
•Open the throttle and allow engine to reach operating temperature. Open throttle fully, do not use the throttle as a
means to match the arbor shaft speed to the specified blade speed requirements.
Be certain to use the proper blade for the machine.
Note: T o ensure that the necessary power is transferred to the blade, all cutting
must be done at full throttle. The governor is factory set for correct speed altering this setting may damage the machine. Maintain the engine according to
factory specifications.

Belt Adjustment and Replacement:
•Periodically check belts for damage, same type and are at the proper tension. Do not mix belts. Slipping belts will
overheat causing the cutting speed to be limited and shorten the life of the belts. Over-tensioned belts will shorten the
life of the belts and bearings.
•On new equipment and after installing new belts of the same type, be certain to re-tension the belts after the first 4
hours of use. New belts are stiff and require a break in period. Belts that are loose could slip and/or overheat.
•Damaged, stretched or excessively worn belts should be replaced with a new complete set of belts of the same
type. Do not mix belts.
Important!
•Belts must be replaced as a complete set of the same type, do not mix
belts even if only one belt is showing wear.
•Blade must be realigned every time the belts are tensioned.
On Gasoline Models:
•Access belts from back of machine.
•Unlock belt guard and lift top portion out of the way .
Water pump and drive belts are now accessible.
•T o change water pump belt, follow “disengage”
instructions on page 9.
