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.
A
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.
When felling in the vicinity of roads,
railways, power lines, etc., take extra
precautions. If necessary, inform the
police, utility company or railway
authority.
Cutting
Work calmly and carefully – in daylight
B
conditions and only when visibility is
good. Stay alert so as not to endanger
others.
Use the shortest possible guide bar: The
chain, guide bar and chain sprocket
must match each other and your saw.
