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.
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, clutch 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.
Do not use waste oil. Renewed
contact with waste oil can cause
skin cancer. Moreover, waste oil is
environmentally harmful.
Waste oil does not have the
necessary lubricating properties
and is unsuitable for chain
lubrication.
