The chain saw may be used to fell only trees
which are smaller in diameter than the length of
the 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 therefore
twice the length of the tree being felled. (Fig, 11)
Felling trees is dangerous and requires
practice.
If
you
inexperienced, do not try to teach yourself but
seek professional training. (Fig. 12)
Falling direction:
First estimate the direction of fall, taking into
•
account the centre of gravity of the crown and
the wind direction. The chain saw must be
running before it comes into contact with the
wood. Switch on the chain saw. Saw an
undercut in the tree in the direction of fall and
then make a horizontal cut (back cut) on the
side opposite to the undercut.
Make the undercut: This will give the tree a
•
direction and guidance.
•
Check the direction of fall: If you have to
correct the undercut, always re-cut over the
entire width.
Call now "Timber! "
•
Only now make the back cut, which must be
•
higher than the sole of the undercut. Insert
wedges in time.
Leave the bridge in place as it will function as
•
a hinge. If you cut through the bridge, the tree
will fall randomly.
•
Fell the tree by driving a wedge into the back
cut, not by sawing through it.
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:
If you can longer distinguish details within the
•
danger zone, e.g. owing to fog, rain, snow
drifts or twilight.
are

beginner
•
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 fell the tree, you must drive a wedge into the
back cut. When retreating after making the back
cut, watch out for falling branches.

Maintenance and cleaning

Always pull the plug out of the power socket
before doing any work on the chainsaw!
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 your
Customer Service. Do not modify the chain saw
in any way as this could jeopardize its safety.
Should the chainsaw fall despite our careful
manufacturing and inspection procedures, have it
repaired by an authorized Customer Service
work-shop. In the event of any inquiries and
spare parts orders, always quote the type
designation and the parts number.
