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 BARS

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 either vacuum and/or water mist, the operator
and any bystanders should always wear a respirator approved by NIOSH/MSHA for the
material being cut.

Head Protection

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 pinhole 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 (4 to 6 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.

You Are Responsible For Your Safety!!!

clean. The Water Curtain should be used when wet cutting to reduce the amount of debris
thrown from the blade and cutting surface. When dry cutting the Water Curtain can be
removed to allow the dust particles to drift away from the Saw Operator. See Figure 9:
