For automatic and reliable lubrication of
the chain and guide bar – use only an
environmentally compatible quality
chain and bar lubricant. Rapidly
biodegradable STIHL BioPlus is
recommended.
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 formulated 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
lubricating properties and is unsuitable
for chain lubrication.
NOTICE
A full chain oil tank is sufficient for only
half a tankful of fuel. Check the oil level
regularly during cutting work. Never
allow the oil tank to run dry.
Preparations
N Thoroughly clean the tank cap and
the area around it to ensure that no
dirt falls into the tank.
N Position the machine so that the
tank cap faces up.
Opening
N Raise the grip until it is upright.
N Turn the cap counterclockwise
(about a quarter turn).
Marks on tank cap and oil tank must line
up.
