information in the safety rules before you be-

gin. If you donot understand the safety rules,

do not attempt to fuel your unit. Contact an

authorized service dealer.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri-

cation. Lubrication is provided by the auto-

matic oiler system when the oil tank is kept

filled. Lack of oil will quickly ruin the bar and

chain. Too little oil will cause overheating

shown by smoke coming fromthe chain and/

or discoloration of the bar.

Only use Bar and Chain Oil for bar and chain

lubrication.

FUELING ENGINE

WARNING: Remove fuel cap slowly

when refueling.

This engine is certified to operate on unleaded

gasoline. Before operation, gasoline must be

mixed with a good quality 2-cycle air-cooled

engine oil designed to be mixed at a ratio of

40:1. A 40:1 ratio is obtained by mixing 0,125

liter of oil with 5 liters of unleaded gasoline. DO

NOT USE automotive or boat oil. These oils

will cause engine damage. When mixing fuel

follow the instructions printed on the container .

Always read and follow the safety rules relating

to fuel before fueling your unit.

IMPORTANT

Experience indicates that alcohol blended

fuels (called gasohol or using ethanol or

methanol) can attract moisture which leads

to separation and formation of acids during

storage.Acidic gas can damage the fuelsys-

tem of an engine while in storage. To avoid

engine problems, empty the fuel system be-

fore storage for 30 days or longer. Drain the

gas tank, start the engine and let it run until

the fuel lines and carburetor are empty. Use

fresh fuel next season. Never use engine or

carburetor cleaner products in the fuel tank

or permanent damage may occur.
