Maintenance and repairs
The machine must be serviced regularly.
Do not attempt any maintenance or
repair work not described in your
Owner’s Manual. All other work should
be carried out by a servicing dealer.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers. STIHL
dealers receive regular training and are
supplied with technical information.
Use only high-quality replacement parts,
in order to avoid the risk of accidents or
damage to the machine. Contact a
dealer if in doubt.
STIHL recommends the use of genuine
STIHL spare parts. Such parts have
been optimized for the machine and the
user's requirements.
Before starting any maintenance or
repair work and before cleaning the
machine, always
stop the engine and
disconnect the spark plug boot
to
avoid all
risk of injury
if the engine
starts up inadvertently. – Exception:
adjustment of carburetor and idle speed.
Do not service or store the machine near
a naked light –
risk of fire
due to the
fuel.
Check fuel cap regularly for tightness.
Use only the spark plugs approved by
STIHL – see Specifications.
Inspect ignition lead (insulation in good
condition, secure connection).
To reduce the
risk of fire
due to ignition
outside the cylinder, move the slide
control / stop switch to
STOP
or
0
before
turning the engine over on the starter
with the spark plug boot removed or the
spark plug unscrewed.
Check that the muffler is in perfect
working condition.
Do not use the machine if the muffler is
damaged or missing –
risk of fire! –
Hearing damage!
Do not touch the hot muffler –
risk of
burns!
The condition of the anti-vibration
buffers influences the machine's
vibrations – they must be examined
regularly.
STIHL power tool attachments are
available for converting the single
purpose unit into other power tool
combinations.
