Instruction Manual

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.
3.5 Pull-in (A)
001BA037 KN
A
Pull-in occurs when the chain on the bottom of
the bar is suddenly pinched, caught or encoun‐
ters a foreign object in the wood. The reaction of
the chain pulls the saw forward – to reduce this
risk, always engage the spiked bumper securely
in the tree or limb.
3.6 Pushback (B)
001BA038 KN
B
Pushback occurs when the chain on the top of
the bar is suddenly pinched, caught or encoun‐
ters a foreign object in the wood. The reaction of
the chain drives the saw straight back toward the
operator – to avoid this risk:
–
Be alert to situations that may cause the top of
the guide bar to be pinched
–
Do not twist the guide bar in the cut
3.7 Exercise extreme caution
–
with leaners
–
with trees that have fallen unfavorably
between other trees and are under strain
–
when working in blowdown areas.
In these cases, do not use a chain saw – use a
hoist, winch or drag line instead.
Pull out exposed and cleared logs. Select clear
area for cutting.
Deadwood (dry, decayed or rotted wood) repre‐
sents a considerable risk that is difficult to
assess. Identifying the extent of the dangers is
complicated, if not impossible. Use aids such as
a cable winch or tractor in such cases.
When felling in the vicinity of roads, railways,
power lines, etc., take extra precautions. If nec‐
essary, inform the police, utility company or rail‐
way authority.
4 Working Techniques
Sawing and felling work, including all related
work (plunge cutting, limbing, etc.) may only be
carried out by persons who have been specially
trained and instructed. Persons who are not
experienced chain saw users should not carry
out any such work – increased risk of accidents!
Country-specific legislation on felling technique
must be complied with during felling work.
