English
– Do not attempt plunge cuts if you
are not experience in this cutting
technique.
– Be wary of position of log and forces
that may cause the cut to close and
pinch the chain.
– Always cut with a correctly
sharpened, properly tensioned
chain – the depth gauge setting
must not be too large.
Use reduced kickback chain and a guide
bar with a narrow radius nose.

Vibrations
Prolonged use of the unit may result in
vibration-induced circulation problems in
the hands (whitefinger disease).
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)
– breaks
The period of usage is shortened by:
– Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, itching).
– Low outside temperatures.
– Gripping force (a tight grip hinders
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear, seek medical advice.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in your owner's manual.

STIHL dealer. Only use genuine STlHL
replacement parts. Never modify your
machine in any way as this could result
in serious injury.

– before replacing the chain.
– before rectifying problems.
Check the chain catcher –
and replace it if damaged.
Observe sharpening instructions
for safe and correct handling of saw
chain and guide bar.

times. It must be properly sharpened,
