Chain Lubricant

For automatic and reliable lubrication of
the chain and guide bar – use only a
quality, environmentally compatible
chain and bar lubricant – preferably the
rapidly biodegradable STIHL Bioplus.
Biological chain oil must be sufficiently
resistant to aging (e. g., STIHL Bioplus).
Oil with a low resistance to aging tends
to turn to resin quickly. This results in
hard deposits that are difficult to remove,
especially in the area of the chain drive
and on the saw chain – .possibly even
causing 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 oil.
Do not use waste oil! Prolonged and
repeated contact with waste oil can
cause skin cancer. It also harms the
environment!
Waste oil does not have the necessary
lubricant properties and is unsuitable for
chain lubrication.
