Instruction Manual

No general recommendation can be given for the
length of usage because it depends on several
factors.
The period of usage is prolonged by:
–
Hand protection (wearing warm gloves)
–
Work breaks
The period of usage is shortened by:
–
Any personal tendency to suffer from poor cir‐
culation (symptoms: frequently cold fingers,
tingling sensations).
–
Low outside temperatures.
–
The force with which the handles are held (a
tight grip restricts circulation).
Continual and regular users should monitor
closely the condition of their hands and fingers. If
any of the above symptoms appear (e.g. tingling
sensation in fingers), seek medical advice.
2.11 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 per‐
formed by a servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer. STIHL dealers are
regularly given the opportunity to attend training
courses and are supplied with the necessary
technical information.
Only use high-quality replacement parts in order
to avoid the risk of accidents and damage to the
machine. If you have any questions in this
respect, consult a servicing dealer.
STIHL recommends the use of original STIHL
replacement parts. They are specifically
designed to match your model and meet your
performance requirements.
To reduce the risk of injury, always shut off the
engine before carrying out any maintenance or
repairs or cleaning the machine. – Exception:
Carburetor and idle speed adjustments.
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.
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 inter‐
vals.
Use only a spark plug of the type approved by
STIHL and make sure it is in good condition –
see "Specifications".
Inspect the ignition lead (insulation in good con‐
dition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire 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.
2.12 Symbols on Deflectors
An arrow on the deflector shows the correct
direction of rotation of the cutting attachments.
Some of the following symbols are applied to the
outside of the deflector to indicate the approved
combination of cutting tool and deflector.
Use deflector in combination with
mowing heads only. Do not use metal
cutting attachments.
Do not use deflector with brush kni‐
ves or circular saw blades.
Do not use deflector with mowing
heads.
Use deflector in combination with
grass cutting blades only.
2.13 Shoulder strap

the shoulder strap.
