STIHL recommends you use the STIHL
filler nozzle for fuel (special accessory).
WARNING
After fueling, close the tank cap carefully
and tighten it down as securely as
possible by hand.
Changing the Fuel Pickup Body
Change the fuel pickup body every year:
N Drain the fuel tank.
N Use a hook to pull the fuel pickup
body out of the tank and take it off
the hose.
N Push the new pickup body into the
hose.
N Place the pickup body in the tank.
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 oil filler cap
and the area around it to ensure that
no dirt falls into the tank.
N Position the machine so that the
filler cap is facing up.
N Open the filler cap.
Filling chain oil tank
N Refill the chain oil tank every time
you refuel.
