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 formu‐
lated 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 lubricat‐
ing properties and is unsuitable for chain lubrica‐
tion.
