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. Do 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
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 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.

A. Safety Precautions
1. Before mounting any blade on the saw: the blade should be inspected for
any damage which might have occurred during shipment, handling or
previous use.
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 bolt which is a left hand thread bolt on the operator’s right
hand side and right hand thread on the operator’s left hand side 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. Use 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.

NOTE: Batteries are shipped with out Electrolytes.
Warning: The electrolyte is sulfuric acid. Read and observe all
instructions and safety precautions on container. Wear
safety goggles while handling and pouring the electrolyte.
The electrolyte should be added to the battery in an area
where running water is quickly available for rinsing, should it
come in contact with the body. Before disposing of the container, empty
and rinse thoroughly with water.
6. Attach the Red Battery Cable to the Positive Battery Terminal and attach
the Black Battery Cable to the Negative Battery Terminal.
7. Reattach the Rear Console Cover.
8. Make sure the hydraulic pump is filled with fluid (See section on hydraulic
pumps).
9. Check the engine oil. The engine has been filled with oil and test run at the
factory and should not require the addition of oil. Oil capacity of crankcase
is 6.4 U.S. quarts (6.1 liters).
10.Fill the fuel tank with Diesel fuel. NOTE: Units are shipped with out fuel.
11.Attach the Muffler and Muffler Retaining Clamp.
Read and understand the remaining sections of this Owners Manual.

D. Water Supply
Pressurized source: Turn the water control to full "ON" when using wet
cutting blades. The required flow rate is 5 to 8 gallons per minute.
Optional Water Pump: The optional water pump is centrifugal pump
designed to boost the flow rate of the water. In order for the optional water
pump to work correctly the system requires a pressurized water source or
the water source must be above the pump. The optional water pump will
not draw water from a supply tank. The part number for the optional water
pump kit is 237243.
1. Centrifugal pumps have a single rotating impeller. Liquid enters at the
center and is thrown outward radically by the centrifugal force. The impeller
is not in contact with other parts resulting in quiet efficient pumping action.
This pump is not self priming. It must be located below the liquid level so
liquid will flow to it by gravity. Air traps in piping must be avoided. Avoid
down loops where air can be trapped.
2. Excessive system pressure above 15 P.S.I. is not recommended as he
seal could be forced out of the pump housing. If water is to be pumped to
the saw; always place an inline shut-off valve in front of the water pump.
3. Replacement Water Pump Seal Kit: Part Number 107523
E. Operating the Saw
Before beginning inspect the work area, machine, and blade for problems or
hazards. Some areas may have underground utilities (water, gas lines, or
electrical lines) located and mark all utilities before beginning. Do not run this
machine or any internal combustion engine indoors or underground with out
proper ventilation and a proper exhaust system for indoors or underground
usage. The machine is not supplied with the proper exhaust for indoors or
underground usage.

20
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.
