WARNING
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.
► Turn the fuel tank cap about 1/8 of a turn
counterclockwise.
If the fuel tank is under pressure, you will hear pressure
being released.
► When the tank is no longer under pressure: Turn the tank
cap counterclockwise until the marks on the cap and fuel
tank are in alignment.
► Remove the fuel tank cap.
NOTICE
Bright light, sunlight and extreme temperatures can cause
the fuel mix to separate much faster. The saw can be
damaged if it is used with a fuel mix that has become
separated.
► Thoroughly mix the fuel.
► Do not use fuel mix that has been stored for more than 30
days.
► Fill the tank to within no more than 15 mm of the brim,
taking care not to spill any fuel.
► If the grip on the fuel tank cap has dropped into the closed
position: Raise the grip until it is vertical.
