Clear escape paths, eliminate obstacles
–
Put down tools and equipment at a safe dis‐
tance – but not on the escape paths
–
When felling, stand only to the side of the fall‐
ing trunk and only move back laterally onto the
escape path
–
Plan escape paths on slopes parallel to the
slope
–
When walking away along the escape path,
watch out for falling limbs and watch the top of
the tree.
Preparing work area at base of tree
–
First clear the tree base and work area from
interfering limbs and brush to provide a secure
footing.
–
Carefully clear the base of the trunk (e.g., with
an axe) – sand, stones and other foreign
objects will blunt the saw chain

The felling notch (C) determines the direction of
fall.
Important:
–
Make a felling notch at right angle to direction
of fall
–
Saw as close to the ground as possible
–
Cut to a depth of approx. 1/5 to 1/3 of the
diameter of the trunk
Determine direction of fall with gunning sight on
cover and fan housing
001BA153 KN
Your chainsaw has a gunning sight on the cover
and fan housing. Use this gunning sight.
Making the felling notch
When making a felling notch, align the chainsaw
so that the notch lies at a right angle to the direc‐
tion of fall.
During the procedure, various sequences are
permitted for making a felling notch with a bottom
(horizontal) cut and top (angled) cut – comply
with national legislation regarding felling techni‐
que.
► Make a bottom (horizontal) cut
► Make the top (angled) cut approx. 45°‑ 60° to
the bottom cut
Checking the direction of fall
001BA153 KN
► Insert the chainsaw with guide bar in the bot‐
tom of the felling notch. The gunning sight
must point in the planned direction of fall – if
necessary, correct direction of fall by re-cutting
the felling notch.
