4.7 Fuel Mixture and Refueling

WARNING

■

This chainsaw requires a fuel mixture of gaso‐ line and two-stroke engine oil. Fuel mixture

and gasoline are extremely flammable. If fuel mixture or gasoline make contact with open fire or hot objects, they can cause a fire or explosion. This can result in serious or fatal injuries and damage to property. ►

Protect fuel mixture and gasoline from heat

and fire. ► Do not spill fuel mixture and gasoline. ► If fuel has been spilled: Wipe up the fuel

with a cloth and do not attempt to start the

engine until all parts of the saw and the

area around it are dry. ►

Do not smoke. ► Never refuel near a fire. ► Shut off the engine and allow it to cool

down before refueling. ► Start the engine at least 3 meters from the

fueling spot, outdoors only.

■ Inhaling fuel fumes and gasoline fumes can have toxic effects. ► Avoid inhaling fuel fumes or gasoline

fumes.

► Refuel in a well-ventilated location.

■ The chainsaw becomes hot during operation, or in a very hot environment. Depending on the type of fuel, altitude, ambient temperature and the temperature of the saw, the fuel expands and can cause a pressure build-up in the tank. Fuel may escape as a spray and ignite when the fuel tank cap is opened. This can result in serious injuries and damage to property. ► Allow the saw to cool down before opening

the tank cap.

► Open the tank cap slowly in stages.

■ Clothing that has been in contact with fuel or gasoline is more easily flammable. This can result in serious or fatal injuries and damage to property. ►

If your clothing comes into contact with fuel or gasoline: Change your clothing.

■ Fuel mix, gasoline and two-stroke engine oil can harm the environment. ► Do not spill fuel, gasoline or two-stroke

engine oil.

► Dispose of fuel mix, gasoline and two-

stroke engine oil in accordance with local regulations and environmental require‐ ments.

■

Fuel, gasoline or two-stroke engine oil can cause irritation if they come into direct contact with the skin or eyes. ►

Avoid contact with fuel, gasoline and twostroke engine oil.

6 0458-787-8321-B

4 Safety Precautions English

► In case of contact with the skin: Wash

affected areas with plenty of water and soap.

►

In case of contact with the eyes: Rinse eyes with plenty of water for at least 15 minutes and seek medical advice.

■

The saw’s ignition system produces sparks. Unconfined sparks may cause a fire or an explosion in an easily combustible or explo‐ sive environment. This can result in serious or fatal injuries and damage to property. ►

Use the spark plugs described in this

instruction manual. ► Insert and tighten down the spark plug. ► Connect the spark plug boot and press it

down firmly.

■ The saw can be damaged if it is run on a fuel mixture consisting of unsuitable gasoline or an unsuitable two-stroke engine oil or if an incor‐ rect mix ratio of gasoline and two-stroke engine oil is used. ►

Mix the fuel as described in this instruction manual.

■ The mixture of gasoline and two-stroke engine oil can separate if it is stored for a long period. The saw can be damaged if it is used with a fuel mix that has separated. ►

Before refueling the saw: Thoroughly mix the fuel.

► Use a mixture of gasoline and two-stroke

engine oil that is not older than 30 days (STIHL MotoMix: 2 years).

4.9 Reactive Forces

4.9.1 Kickback

WARNING

If kickback occurs, the saw can be thrown up

■ in the direction of the operator. The operator

can lose control of the saw and be seriously or fatally injured. ►
