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, 12)
Felling trees is dangerous and requires practice. If
you are a beginner or inexperienced, do not try to
teach yourself but seek professional training.
(Fig, 13)
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.
● 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.
11. 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 our Customer Service. Do not modify the
power 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.
Storage
Keep your chain saw in a safe place. The unused
chainsaw should be stored clean, on a flat surface and
in a dry place which is inaccessible to children
