OIL AND PETROL INFORMATION

Old and/or improperly mixed petrol are usually the main reasons for the unit not running properly. Be sure to use fresh, clean petrol and follow the instructions carefully for the proper petrol/oil mixture.

RECOMMENDED OIL TYPE

Use a high quality oil formulated for use in 2-cycle, air-cooled engines.

RECOMMENDED PETROL TYPE

Always use clean, fresh, unleaded petrol (gasoline) that is less than 60 days old.

WARNING: petrol (gasoline) is extremely flammable and its vapors can explode if they are ignited. Always stop the engine and allow it to cool before filling the petrol tank. Do not smoke while filling the tank. Keep sparks and open flames away from the area.

OIL AND PETROL MIXING INSTRUCTIONS

Thoroughly mix 5 liters of unleaded petrol (gasoline) with 125 ml. of 2 cycle engine oil in a separate petrol can (40:1). Do not mix them directly in the engine petrol tank.

STARTING/STOPPING INSTRUCTIONS

STARTING INSTRUCTIONS

1. Mix petrol (gasoline) with oil. Fill petrol tank with petrol/oil mixture. See Oil and Petrol Mixing Instructions.
