FUEL AND REFUELLING

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 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.

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.
