Checking for proper closure
N
The lug on the grip must engage
entirely in the recess (arrow), and
the grip must lie completely flush
with the top of the cap.
N
Grip the cap and check for
tightness.
N
If the cap can be moved, it is not
properly installed.
Misalignment of the cap parts
N
If the cap does not drop fully into the
opening when the positioning marks
line up and/or if the cap does not
tighten properly when twisted, the
base of the cap may be rotated out
of position vis-à-vis the top.
N
Such misalignment can result from
handling, cleaning or an improper
attempt at tightening.
N
To correct a misalignment, turn the
cap (with the grip up) until it drops
fully into the tank opening.
N
Twist the cap counterclockwise as
far as it will go (approx. 1/4 turn) –
this will twist the base of the cap into
the correct position.
N
Twist the cap clockwise, closing it
normally – see the sections
"Closing" and "Checking for proper
closure."
N
If your cap still does not tighten
properly, it may be damaged or
broken; immediately stop use of the
unit and take it to your authorized
STIHL dealer for repair.
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.
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.

Chain Lubricant
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.
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.
