Fuel
 Petrol and fuel are extremely flammable.
If spilled or ignited by ignition source, it can cause fire and serious injury or
property damage.
Extreme caution is required when handling petrol or fuel.
 After refuelling, tighten fuel cap firmly and check for leakage.
In case of fuel leakage, repair before starting operation since there is a danger of
fire.
1. Oil tank cap
2. Fuel tank cap
A: Tightening direction
 Use an appropriate type of fuel container.
 Bring an extinguisher or shovel in case of fire.
Despite the precautions which can be taken, operating a chain saw, or just working in the
forest, presents dangers.
 Do not smoke or bring flame or sparks near to fuel supplies.
 The fuel tank may be under pressure.
Always loosen the fuel cap and wait for pressure to be equalized before removing the cap.
 Fill the fuel tank outdoors over bare ground and install the fuel cap securely.
Do not pour fuel indoors.
 Wipe any spilled fuel off the unit.
 Never refuel while the engine is still hot, or fuel a running engine.
 Do not store the unit with fuel in its tank, because a fuel leak could start a fire.
Starting engine
 Move the chain saw at least 3 m from the fuelling point before starting the engine.
 Do not allow other persons to be near the chain saw when you are starting or cutting with
the chain saw.
Keep bystanders and animals out of the work area.
Do not let anyone hold wood for you to cut.
 Do not start cutting until you have a clear work area, secure footing and a planned retreat
path from the falling tree.
 Before you start the engine, make sure that the saw chain is not contacting anything.
 Keep the handles dry, clean, and free of oil or fuel mixture.
 Operate the chain saw only in well-ventilated areas.
Exhaust gas, oil mist (from chain saw lubrication) or saw dust is harmful to health.
Transportation
1. Guide bar cover
 When transporting your chain saw, use the appropriate guide bar cover.
 Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and
the silencer away from your body.
