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.
–
Limbs under tension:
Always start relieving cut 1) at the
N
compression side (A).
Make relieving cut (1) and then
N
perform bucking cut (2) at the
tension side (B) – the saw will
otherwise pinch or kick back.
If not otherwise possible, make the
bucking cut from the bottom upwards
(underbuck) – be wary of pushback.

Cutting
Begin cutting with the saw at full throttle
and (if possible) engage the spiked
bumper firmly in the wood, and then
continue cutting.
Do not operate your saw with the
starting throttle lock engaged. Engine
B
speed cannot be controlled with the
throttle trigger in this position.
Always work with the spiked bumper so
that you have better control of the saw. If
you work without the spiked bumper the
saw may pull you forwards suddenly.
Always pull the saw out of the cut with
the chain running.
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.
Cutting techniques:
Cut straight through thin limbs
–
In case of thick limbs, first perform
–
relieving cut from below (approx. 1/5
of diameter), then buck from above
Support and secure heavy
–
branches with ropes.
Never work on a ladder or on any other
insecure support, do not work above
shoulder height.
If conditions allow, work from a lift
bucket.
Cordon off the work area in order to
reduce the risk of injuries and damage to
property from falling branches (e.g.
motor vehicles).
When working with a lifeline there is a
risk of cutting through the rope – to
reduce the risk of fall injuries , always
use double lifelines.
