FELLING TREES
To fell trees, observe all the safety regulations and
proceed as follows:
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 (See 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.
FALLING DIRECTION (See fig.13):
• First estimate the direction of fall, taking into account
the centre of gravity of the crown and the wind direc-
tion. The chainsaw must be running before is comes
into contact with the wood. Switch on the chainsaw.
Always plan an escape route to a safe location from
where you are working.
Place the chainsaw on the ground and do not run with
it switched on or off.
• Cut a “felling notch” perpendicular to the line of fall,
close to the ground. Cut the bottom of the notch first,
horizontally and about one third of the way through the
diameter. The second cut is made at a 45 degree angle
that will meet the depth of the first cut. Remove the
“felling notch”.
• Only now make the “felling cut” on the opposite side
of the “felling notch”.
• Begin 1 or 2 inches higher than the centre of the “fell-
ing notch” and cut horizontally towards it. Do not cut
all the way through but leave a hinge that will keep the
tree from kicking back and upward as it falls. The hinge
will be about 1/8 to 1/6 of the diameter where you are
cutting but it may vary, depending on when the tree
starts to fall.
• Now call “TIMBER!” and leave on your planned escape
route. Do not return to the site until the tree is down
and no longer moving.
• If the tree fails to fall, drive non-metallic wedges into
the “felling cut” where necessary to control the fall.
DO NOT FELL TREES:
• If you can no longer distinguish details within the
danger zone, e.g. owing to fog. rain, snow drifts or
twilights.
• If the direction of fall cannot be reliably estimated ow-
ing 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.
MAINTENANCE AND CLEANING
Always pull the plug out of the power socket before do-
ing 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
the Osaki repair and service facility. Do not modify the
chainsaw in any way as this could jeopardise its safety.
Should the chainsaw fail despite our careful manufac-
turing and inspection procedures, have it repaired by
the Osaki repair and service facility. In the event of any
inquiries and spare parts orders, always quote the type,
model and the part number.
STORAGE
Keep your chainsaw in a safe place. The unused chain-
saw should be stored clean, on a flat surface and in a
dry place which is inaccessible to children.
ENVIRONMENT
Should your machine need replacement after extended
use, do not put it in the domestic waste but dispose of
it in an environmentally safe way.
