Chain Lubricant
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.
