English
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, there may be
sparks, which under certain conditions
can cause easily combustible materials
to catch fire. Even dry plants and scrub
are easily combustible, especially in hot,
dry weather conditions. If there is a risk
of fire, do not use the chain saw in the
vicinity of easily combustible materials,
dry plants or scrub. Always check with
the relevant forestry commission if there
is a risk of fire.
Caution: Risk of electri-
cal shock when cutting
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 –
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 shattered wood
– risk of injury from slivers being caught
and thrown in your direction!
After finishing a cut and before moving
the chain saw to another position in the
tree, secure the chain saw so that it
cannot be accidentally switched on
again – press the hand guard forward
towards the tip of the bar (position ƒ).

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 make a
–
relief cut from below (approx. 1/5 of
the diameter), then saw through
from above
Support and secure heavy
–
branches with ropes.
If the chain saw jams in the cut:
Secure the chain saw so that it
–
cannot be accidentally switched on
again – press the hand guard
forward towards the tip of the bar
(position ƒ) and secure it to the
trunk of the tree
Carefully free the chain saw, if
–
necessary, with another saw
Lying or standing logs under tension:
Always start relieving cut (1) at
N
compression side (A)
Then make bucking cut (2) at the
N
tension side (B) – otherwise the
chain saw may pinch or kick back
If not otherwise possible, make the
bucking cut from the bottom upwards
(underbuck) – risk of kickback!
