Base of improperly aligned
cap (with open space)
Right:
Base of cap correctly posi -
tioned for installation
To correct a misalignment, turn the
N
cap (with the grip up) until it drops
fully into the tank opening.
Twist the cap counterclockwise as
N
far as it will go (approx. 1/4 turn) –
this will twist the base of the cap into
the correct position.
Twist the cap clockwise, closing it
N
normally – see the sections
"Closing" and "Checking for proper
closure."
If your cap still does not tighten
N
properly, it may be damaged or
broken; immediately stop use of the
unit and take it to your authorized
STIHL dealer for repair.

Chain Lubricant
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, clutch 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.
Do not use waste oil. Renewed contact
with waste oil can cause skin cancer.
Moreover, waste oil is environmentally
harmful.
Waste oil does not have the necessary
lubricating properties and is unsuitable
for chain lubrication.
Filling Chain Oil Tank
Preparations
Thoroughly clean the oil filler cap
N
and the area around it to ensure that
no dirt falls into the tank.
Position the machine so that the
N
filler cap is facing up.
Open the filler cap.
N
Filling chain oil tank
Refill the chain oil tank every time
N
you refuel.
Take care not to spill chain oil while
refilling and do not overfill the tank.
Close the filler cap.
N
There must still be a small amount of oil
in the oil tank when the fuel tank is
empty.
If the oil level in the tank does not go
down, the reason may be a fault in the oil
supply system: Check chain lubrication,
clean the oilways, contact your dealer
