Kickback occurs, e.g.
–
when the upper quadrant of the bar
nose unintentionally contacts wood
or another solid object, e.g. when
another limb is touched accidentally
during limbing.
–
when the chain at the nose of the
guide bar is pinched in the cut.
QuickStop chain brake
This device reduces the risk of injury in
certain situations – it cannot prevent
kickback. If activated, the brake stops
the saw chain within a fraction of a
second – for a description of this device
refer to chapter on "Chain Brake" in this
manual.
To reduce the risk of kickback
–
Work cautiously and avoid
situations which could cause
kickback.
–
Hold the saw firmly with both hands
and maintain a secure grip.
–
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 previous cut.
–
Do not attempt plunge cuts if you
are not experienced 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, properly tensioned
chain – the depth gauge setting
must not be too large.
–
Use a low kickback chain and a
narrow radius guide bar.
Pull-in (A)
Pull-in occurs when the chain on the
bottom of the bar is suddenly pinched,
caught or encounters a foreign object in
the wood. The reaction of the chain pulls
the saw forward – always hold the
spiked bumper securely against the tree
or limb.
Pushback (B)
Pushback occurs when the chain on the
top of the bar is suddenly pinched,
caught or encounters a foreign object in
the wood. The reaction of the chain
drives the saw straight back toward the
operator. To avoid pushback.
–
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.
Exercise extreme caution
–
with leaners
–
with trees that have fallen
unfavorably between other trees
and are under strain
Do not work with the chain saw in such
circumstances. Use block and tackle,
cable winch or tractor.
Pull out exposed and cleared logs.
Select clear area for cutting.
Deadwood (dry, decayed or rotted
wood) represents 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.
