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
10
of the chainsaw since it might otherwise go out of
control!
Make sure your saw does not touch any foreign
materials: Stones, nails, etc. may be flung off
and damage the saw chain. The chain saw may
kick back unexpectedly – risk of accident!
If a rotating saw chain hits a stone or another
hard object, sparks may be generated which may
ignite easily flammable materials under certain
conditions. Also dried-out plants and brushwood
are combustible, above all in hot and dry
weather. If there is a risk of fire, do not use the
chain saw in the vicinity of easily combustible
materials, dry plants or scrub. It is mandatory
that you ask the responsible forestry office about
the current fire hazard.
Caution! To avoid risk of electrocu‐
tion, take extra precautions when cut‐
ting near power lines. Have the power
switched off before starting cutting
work in the immediate vicinity of
power lines.
Do not underbuck freely hanging limbs because
the chain may get pinched and cause kickback
and loss of control.
Be careful when cutting scrub and young trees.
Thin shoots can be scooped up by the chain saw
and hurled towards the user.
Be careful when cutting splintered wood – Risk of
injury from ejected pieces of wood!
After finishing a cut, activate the chain brake to
lock the chain or shut down the engine before
moving the saw to another position in the tree.
Cutting techniques:
Begin cutting with the chain saw at full throttle.
Always pull the saw out of the cut with the chain
running.
– 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.
If the saw gets pinched in the cut:
– Shut off the engine and secure the saw to the
tree – in direction of trunk.
– Carefully free the saw from the cut, using
another saw if necessary.
