motor still running. If the saw chain gets jammed,
release it using a wooden wedge.
Remember:
Danger zone: Falling trees can bring down
other trees with them. The danger zone is the-
refore twice the length of the tree being felled.
(Fig. 11)
Important:
Prior to cutting you must plan and provide for an
escape area (A). This escape area must be located
behind the expected felling direction (B)
(Fig. 13
).
Important:
Before performing the final cut, make sure there are
no spectators, animals or obstacles in the felling
path.
Felling direction:
앬
First estimate the direction of fall, taking into
account the centre of gravity of the crown and
the wind direction. The chainsaw must be run-
ning before it comes into contact with the wood.
Switch on the chainsaw. Saw an undercut in the
tree in the direction of fall and then make a hori-
zontal cut (back cut) on the side opposite to the
undercut.
앬
Make the undercut: This will give the tree direc-
tion and guidance.
앬
Check the direction of fall: If you have to correct
the undercut, always recut over the entire width.
앬
Call out „Timber!“
앬
Only now make the back cut, which must be hig-
her than the sole of the undercut. Insert wedges
in good time.
앬
Leave the bridge in place as it will function as a
hinge. If you cut through the bridge, the tree will
fall randomly.
앬
Fell the tree by driving a wedge into the back cut,
not by sawing through it.
앬
When the tree falls, step back and watch the
crown. Wait for the crown to stop swinging. Do
not continue working under branches which have
got stuck.
Do not fell trees:
앬
if you can no longer distinguish details within the
danger zone, e.g. owing to fog, rain, snow drifts
or twilight,
앬
if the direction of fall cannot be reliably estimated
owing to wind or gusts of wind. Felling work on
sloping ground, black ice, frozen or dewy ground
is safe only if you can get a firm foothold.
To switch off:
Pull the plug out of the power socket. To fell the tree,
you must drive a wedge into the back cut. When
retreating after making the back cut, watch out for
falling branches.
Wood under tension

tension
Danger:
Tree will move downwards!

Danger:
Tree will move suddenly and
with immense force!

tension
Danger:
Tree will move sideways!
Maintenance and cleaning
Always pull the plug out of the power socket
before doing any work on the machine!
Keep the cooling vents on the motor housing clean
and unobstructed at all times. Only the maintenance
work described in these operating instructions may
be carried out. Any other maintenance work must be
carried out by our Customer Service. Do not modify
the chainsaw in any way as this could jeopardize its
safety. Should the machine fail despite our careful
manufacturing and inspection procedures, have it
repaired by an authorized Customer Service works-
hop. In the event of any inquiries and spare parts
orders, always quote the type designation and the 9-
digit order number.
Storage
Keep your chainsaw in a safe place.
The unused
machine should be stored clean, on a flat surface
and in a dry place which is inaccessible to children.
