FUEL HANDLING

Fuel safety

Never start the machine:

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

2If you have spilt 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 petrol 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.

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 petrol 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.

Petrol

CAUTION! Always use a quality petrol/oil mixture at least 90 octane (RON). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter.

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

The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature, 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 JONSERED 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.

A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters.

Mixing ratio

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

1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.
