WARNING
An improperly tightened fuel filler cap
can loosen or come off and spill
quantities of fuel. To reduce the risk of
fuel spillage and fire from an improperly
installed fuel cap, tighten the fuel filler
cap by hand with as much force as
possible:
N If your fuel cap still does not tighten
properly, it may be damaged or
broken. Stop using the chain saw
and take it to your authorized STIHL
dealer for repair or replacement.
Change the fuel pickup body
Change the fuel pickup body every year.
N Open the filler cap and drain the fuel
tank.
N Use a hook to pull the fuel pickup
body out of the tank and take it off
the hose.
NOTICE
Do not kink the fuel hose – do not use
any sharp or pointed tools.
N Push the new pickup body into the
hose.
N Place the pickup body in the tank
and close the filler cap.
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.
