FUEL HANDLING

General

!

WARNING! Running an engine in a confined

or badly ventilated area can result in death

due to asphyxiation or carbon monoxide

 

poisoning. Use fans to ensure proper air

 

circulation when working in trenches or

 

ditches deeper than one meter (3 foot).

Fuel and fuel fumes are highly inflammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!

Do not smoke and do not place any hot objects in the vicinity of fuel.

Fuel

NOTICE! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

Gasoline

Use good quality unleaded gasoline.

The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.

When working at continuous high revs a higher octane rating is recommended.

Environment fuel

HUSQVARNA recommends the use of alkylate fuel or environment fuel for four-stroke engines blended with two- stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor).

Two-stroke oil

K760

For best results and performance use HUSQVARNA two- stroke engine oil, which is specially formulated for our air- cooled two stroke-engines.

Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

Never use oil intended for four-stroke engines.

K760 OilGuard

Use HUSQVARNA OilGuard two stroke oil.

Mixing

Always mix the gasoline and oil in a clean container intended for fuel.

Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline.

Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.

Do not mix more than one month’s supply of fuel at a time.
