Filling Up with Fuel
Take care not to spill fuel while fueling 
and do not overfill the tank.
STIHL recommends you use the STIHL 
filler nozzle for fuel (special accessory).
N Fill up with fuel.
Closing the Tank Cap
N Place the cap in the opening.
N Turn the cap clockwise as far as 
stop and tighten it down as firmly as 
possible by hand.
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.
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 formulated 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 
lubricating properties and is unsuitable 
for chain lubrication.
Preparations
N Thoroughly clean the fuel cap and 
the area around it to ensure that no 
dirt falls into the tank
N Position the machine so that the fuel 
cap is facing upwards
