33 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 and chain. It may even cause 
the oil pump to seize.
