Husqvarna Essential Fuel Safety and Mixing Guide for Brush Cutters

FUEL HANDLING

Fuel safety

Never start the machine:

1If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.

2If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

Transport and storage

Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.

When storing and transporting fuel always use approved containers intended for this purpose.

When storing the machine for long periods the fuel tank must be emptied. Contact your local gas station to find out where to dispose of excess fuel.

Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage.

Secure the machine during transport.

!

WARNING! Take care when handling fuel.

Bear in mind the risk of fire, explosion

 

 

and inhaling fumes.

Fuel

CAUTION! 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.

!

WARNING! 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.

Gasoline

CAUTION! Always use a quality gasoline/oil mixture with an octane rating of at least 87 octane ((RON+MON)/2). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded gasoline/oil mixture. Leaded gasoline will destroy the catalytic converter.

Use low-emission gasoline, also known as alkylate gasoline, if it is available.

This engine is certified to operate on 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.

Two-stroke oil

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.

Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil.
