For automatic and reliable
lubrication of the chain and guide
bar – use only an environmentally
compatible quality chain and bar
lubricant with non-fling additive
or the 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.
