–
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)
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)
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
4 Working Techniques
4.1 Sawing
Do not operate your saw in the starting throttle
position. Engine speed cannot be controlled with
the throttle trigger in this position.
Work calmly and carefully – in daylight conditions
and only when visibility is good. Ensure you do
not endanger others – stay alert at all times.
Use the shortest possible guide bar: The chain,
guide bar and chain sprocket must match each
other and your saw.
Position the saw so that your body is clear of the
cutting attachment.
If conditions allow, work from a lift bucket.
Never work on a ladder or on any other insecure
support, do not work above shoulder height.
Cordon off the work area in order to reduce the
risk of injuries and damage to bystanders or
property (e. g. motor vehicles) from falling
branches.
When working with a lifeline there is a risk of cut‐
ting through the rope – to reduce the risk of fall
injuries,always use double lifelines.
Take special care when cutting through a limb.
Hold the machine firmly to control and counteract
the feed force. At the end of the cut, the chain
saw is no longer supported by the cutting attach‐
ment in the cut. You have to take the full weight
