Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
specialist dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and receive technical
information bulletins on engineering
changes.
Use only high quality replacement parts
since there is otherwise a risk of
accidents or damage to the machine. If
you have any questions in this respect,
consult a specialist dealer.
STIHL recommends you use only
original STlHL replacement parts. The
characteristics of these parts are
specifically designed to match your
chainsaw model and meet your
performance requirements.
To reduce the risk of injury from
unintentional engine startup and chain
rotation, always shut off the engine
and disconnect the spark plug boot
before performing any repairs,
maintenance or cleaning work. –
Exception: Carburetor and idle speed
adjustments.

To reduce the risk of fire, do not service
or store your machine near open flames.
Check the fuel filler cap for leaks at
regular intervals.
Use only a spark plug of the type
approved by STIHL and make sure it is
in good condition – see "Specifications".
Inspect ignition lead (insulation in good
condition, secure connection).
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed unless the slide control /
stop switch is on STOP or 0 since there
is otherwise a risk of fire from
uncontained sparking.
Check condition of the muffler at regular
intervals to reduce the risk of fires and
damage to hearing. Do not operate your
machine if the muffler is damaged or
missing.
Do not touch a hot muffler since burn
injury will result.
Vibration behavior is influenced by the
condition of the AV elements – check
the AV elements at regular intervals.
Check the chain catcher –
and replace it if damaged.
Shut off the engine
– before checking chain tension.
– before retensioning the chain.
– before replacing the chain.
– before rectifying problems.
Observe sharpening instructions
for safe and correct handling of saw
chain and guide bar.
Keep the chain in good condition at all
times. It must be properly sharpened,
tensioned and well lubricated.
Always change the chain, guide bar and
sprocket in good time.
Check condition of clutch drum
periodically.
Store fuel and chain lubricant in properly
labelled, safety-type canisters only. Take
care when handling gasoline. Avoid
direct contact with the skin and avoid
inhaling fuel vapour.
To reduce the risk of injury, stop using
your saw immediately if the chain brake
does not function properly.
Take your saw to your local dealer. Do
not use the chainsaw until the problem
has been rectified (see chapter on
"Chain Brake").
