Never attempt to modify your saw in any way
since this may increase the risk of personal
injury.
Regularly check the electrical contacts and
ensure that the insulation of the connecting cord
and plug shows no sign of aging (brittleness).
Electrical components, e.g. power cord, may only
be repaired or replaced by a qualified electrician.
Check the chain catcher and replace it if dam‐
aged.
Observe sharpening instructions – keep the
chain and guide bar in good condition at all times
for safe and correct handling of the machine. The
chain must be properly sharpened, tensioned
and well lubricated.
Always change the chain, guide bar and sprocket
in good time.
Store chain lubricant in properly labeled, safety-
type canisters only. Store in a dry, cool and safe
location protected from light and the sun.
If there is a problem with the chain brake, switch
off the saw immediately, move the hand guard to
ƒ
and disconnect the plug from the wall outlet –
risk of injury. Contact your servicing dealer – do
not use your saw until the problem has been rec‐
tified (see "Chain Brake").

Reactive Forces
The most common reactive forces that occur dur‐
ing cutting are: kickback, pushback and pull-in.
3.1
Dangers of kickback
Kickback can result in serious or fatal
injury.
001BA036 KN
(Kickback) occurs when the saw is suddenly
thrown up and back in an uncontrolled arc
towards the operator.
3.2
Kickback occurs if, e. g.,
001BA257 KN
–
when the upper quadrant of the bar nose unin‐
tentionally contacts wood or another solid
object, e.g. when another limb is touched acci‐
dentally during limbing.
–
when the chain at the nose of the guide bar is
pinched in the cut.
3.3
Quickstop chain brake:
This device reduces the risk of injury in certain
situations – it cannot prevent kickback. When
activated, the chain brake stops the saw chain
within a fraction of a second –
see the section "Saw chain" in this Instruction
Manual.
3.4
To reduce the risk of kickback
–
Work cautiously and avoid situations which
could cause kickback.
–
Hold the saw firmly with both hands and main‐
tain a secure grip.
–
always cut at full throttle.
–
Be aware of the location of the guide bar nose
at all times.
–
do not cut with the bar nose.
–
Take special care with small, tough limbs, they
may catch the chain.
–
never cut several limbs at once.
–
do not overreach.
–
never cut above shoulder height.
–
Use extreme caution when re-entering a previ‐
ous cut.
–
Do not attempt plunge cuts if you are not
experience in this cutting technique.
–
be alert for shifting of the log or other forces
that may cause the cut to close and pinch the
chain.
–
always cut with a correctly sharpened, prop‐
erly tensioned chain – the depth gauge setting
must not be too large.
–
Use a low kickback chain and a narrow radius
guide bar.
