English
► Place the cap on the opening and rotate it
counterclockwise until it engages the filler
neck.
► Continue rotating the cap counterclockwise
(about a quarter turn) – this causes the bottom
of the cap to be turned to the correct position.
► Turn the cap clockwise and lock it in position –
see section on "Closing".

11 Chain Lubricant

For automatic and reliable lubrication of the
chain and guide bar – use only an environmen‐
tally compatible quality chain and bar lubricant.
Rapidly biodegradable STIHL BioPlus is recom‐
mended.
NOTICE
Biological chain oil must be resistant to aging
(e.g. STIHL BioPlus), since it will otherwise
quickly turn to resin. This results in hard deposits
that are difficult to remove, especially in the area
of the chain drive and chain. It may even cause
the oil pump to seize.
The service life of the chain and guide bar
depends on the quality of the lubricant. It is
therefore essential to use only a specially formu‐
lated chain lubricant.

WARNING
Do not use waste oil. Renewed contact with
waste oil can cause skin cancer. Moreover,
waste oil is environmentally harmful.
NOTICE
Waste oil does not have the necessary lubricat‐
ing properties and is unsuitable for chain lubrica‐
tion.

12 Filling Chain Oil Tank

12.1 Preparations
► Thoroughly clean the oil filler cap and the area
around it to ensure that no dirt falls into the
tank.
► Position the machine so that the filler cap is
facing up.
► Open the filler cap.
12.2 Fill up with chain oil.
► Refill the chain oil tank every time you refuel.
Take care not to spill chain oil while refilling and
do not overfill the tank.
STIHL recommends you use the STIHL filler noz‐
zle for chain oil (special accessory).
► Close the filler cap.
There must still be a small amount of oil in the oil
tank when the fuel tank is empty.
If the oil level in the tank does not go down, the
reason may be a fault in the oil supply system:
Check chain lubrication, clean the oilways, con‐
tact your dealer for assistance if necessary
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer.
