OPERATION

KICKBACK PRECAUTIONS

See Figures 4 and 5.

Rotational kickback occurs when the moving chain con- tacts an object at the Kickback Danger Zone 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 can result in serious injury.

FUEL AND REFUELING

HANDLING THE FUEL SAFELY

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 vapors.

￿Do not let gasoline or oil come in contact with skin.

￿Keep gasoline and oil away from the eyes. If gasoline 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 gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle engine oil in a clean container approved for gasoline.

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

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

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

￿Mix 2% oil into the gasoline. This is a 50:1 ratio.

￿Mix the fuel thoroughly and each time before fueling.

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