OPERATION

WARNING:

KICK-BACKoccurs when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar may cause the chain to dig into the object and stop the chain for an instant. The result is a lightning- fast, reverse reaction which kicks the guide bar up and back towards the operator. If the saw chain is pinched along the top of the guide bar, the guide bar can be driven rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious injury.

Do not rely exclusively upon the safety devices built into your saw. As a chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury.

KICK-BACK PRECAUTIONS

See Figures 4 and 5.

Rotational kick-back (A) occurs when the moving chain contacts an object at the Kick-back Danger Zone (B) of the guide bar. The result is a lightning-fast, reverse reaction which kicks the guide bar up and back towards the operator. This reaction can cause loss of control which may result in serious injury.

FUEL AND REFUELLING

HANDLING THE FUEL SAFELY

WARNING:

Always turn off engine before refuelling. Never add fuel to a machine with a running or hot engine. Move at least

15 m (50 ft.) from refuelling site before starting the engine. DO NOT SMOKE! Failure to heed this warning can result in possible personal injury.

WARNING:

Check for fuel leaks. If any are found, correct them before using the saw to prevent fire or burn injury.

■Always handle fuel with care: it is highly flammable.

■Always refuel outdoors and do not inhale fuel vapour.

■Do not let petrol or oil come in contact with skin.

■Keep petrol and oil away from the eyes. If petrol or oil comes in contact with the eyes, wash them immediately with clean water. If irritation is still present, see a doctor immediately.

■Clean up spilled fuel immediately.

MIXING THE FUEL

■This product is powered by a 2-cycle engine and requires pre-mixing petrol and 2-cycle oil. Pre-mix unleaded petrol and 2-cycle engine oil in a clean container approved for petrol.

■This engine is certified to operate on unleaded petrol intended for motor vehicle use with an octane rating of 87 ([R + M] / 2) or higher.

■Do not use any type of pre-mixed petrol/oil from fuel service stations. This includes the pre-mixed petrol/oil intended for use in mopeds, motorcycles, etc.

■Use a high quality 2-cycle self-mixing oil for air-cooled engines. Do not use motor vehicle oil or 2-cycle outboard oil.

■Mix 2% oil into the petrol. This is a 50:1 ratio.

■Mix the fuel thoroughly each time before refuelling.

■Mix in small quantities. Do not mix quantities larger than usable in a 30-day period. A 2-cycle oil containing a fuel stabiliser is recommended.
