If the filler cap will not engage into the
fuel tank housing
If the cap does not drop fully into the fuel
tank opening when the positioning
marks (1, 2) line up, or if it does not
tighten properly when turned, the base
of the cap may be prematurely rotated in
relation to the top. Such misalignment
can result from handling, cleaning or an
improper attempt at tightening.
– Illustrations A and B: The base of
the cap is prematurely rotated to the
closed position and is not in the
correct starting position for
installation. The tank will not seal in
this configuration. Note: in
Illustrations A and B, the interior
positioning marks (1) are in line with
the exterior position marks (2).
– Illustration C: The bottom of the cap
is in the correct starting position for
installation. Note: In Illustration C,
the interior positioning mark (1) is
under the grip and not in line with
the outer position mark (2).
To return the base of the cap to the
proper starting position for installation:
N Drop the cap into the fuel tank
opening (A).
N Next, turn the cap counter-
clockwise with slight pressure until it
drops fully into the fuel tank opening
(approximately 1/4 turn) (B). This
will rotate the base of the cap into
the correct starting position for
installation (C). The exterior
positioning mark (1) on the cap will
line up with the "unlocked"
symbol (2) on the fuel tank housing.
The interior positioning mark should
be under the grip and not in line with
the outer positioning mark (1).
N Then, turn the cap clockwise,
closing it normally.
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.
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.
