depends on the temperature.
Checking the chain brake
Operate the chain brake by turning your left hand
around the front handle. Push the chain brake lever /
hand guard with the back of your hand towards the
guide bar while the chain is moving quickly. Make
sure that both hands are always on the handles.
WARNING! If the chain brake does not stop the chain
immediately, or if the chain brake does not remain
in the running position without assistance, arrange
for the chain saw to be repaired before further use.
Before each start-up, check all screw and plug
connections and protective devices for strength
and correct seating and to ensure that all moving
parts are turning smoothly.
It is strictly forbidden to dismantle, modify or
remove the protective devices located on the
machine or to install other protective devices.
The machine must not be used if it is
damaged or if the safety devices are defective.
Replace worn and damaged parts.
Check the saw for damage or other defects
before each start-up, especially if the saw has
been dropped, and make sure that no significant
damage has occurred.
Always ensure adequate lighting or good light condi-
tions when working with the machine.
Attention when walking backwards, danger of
tripping!
Remove cut branches immediately from the work
area to prevent injury.
The on/off switch and the safety switch must not be
locked.
Working instructions
Felling a tree
If two or more persons cut and fell at the same time,
the distance between the fellers and the cutters
should be at least twice the height of the tree to
be felled. When felling trees, care must be taken
to ensure that other persons are not exposed to
danger, that no utility lines are in the way and that no
material damage can be caused. If a tree comes into
contact with a utility line, the utility company must be
informed immediately. When sawing on slopes, the
chain saw operator should be on the ground above
the tree to be felled, as the tree is likely to roll or slide
downhill after felling.
An escape route should be planned and, if neces-
sary, cleared prior to the commencement of felling
operations. The escape route should lead diagonally
backwards from the expected fall line.
Before you start felling, consider the natural inclina-
tion of the tree, the position of larger branches and
the direction of the wind in order to estimate the
direction in which the tree will fall.
Remove dirt, stones, loose bark, nails, staples and wire
from the tree.
Do not try to cut trees that have rotted or been dam-
aged by wind, fire, lightning, etc. This is extremely
dangerous and should be done by professional tree
surgeons.
1. Notch cut
At right angles to the direction of fall, saw a notch
with a depth of 1/3 of the tree diameter. First make
the lower horizontal cut. This avoids jamming the saw
chain or guide bar when making the second cut.
2. Felling cut
Make the felling cut at least 50 mm higher than the
horizontal notch cut. Make the felling cut parallel to
the horizontal notch cut. Make the felling cut so that
a strip (felling strip) remains, which can act as a hinge.
The strip prevents the tree from turning and falling in
the wrong direction. Do not saw through the strip. As
the felling cut approaches the strip, the tree should
begin to fall. If there is a danger that the tree will not
fall in the desired direction or it swings back and the
saw chain jams, stop cutting before the felling cut
is complete and use wooden, plastic or aluminium
wedges to expand the cut and make the tree fall in
the desired direction.
When the tree begins to fall, pull the chain saw out
of the cut, turn off the engine, turn off the chain saw
and follow the planned escape route. Pay attention to
falling branches and do not trip.
Removing woody roots
Woody roots are large roots that protrude above the
soil from the trunk of the tree. Large woody roots
must be removed before felling. First cut the woody
root horizontally and then vertically. Remove the
loose root piece from the working area. Follow the
correct procedure for felling the tree after removing
the large woody roots.
Cutting a tree trunk to length
Cutting to length involves cutting a tree trunk into
pieces. It is important that you have a firm footing
and that your weight is evenly distributed on both
feet. Where possible, the trunk should be elevated
and supported by branches, trunks or wooden
wedges. Follow the instructions below to facilitate
cutting: If the trunk is supported over its entire length,
cut it from above (top cut). If the trunk is supported at
one end, cut through a third of the diameter from the
bottom (undercut). Then make the final cut as a top
cut, which meets the first cut.
If the trunk is supported at both ends, cut through
a third of the diameter from the top (top cut). Then
make the final cut as an undercut over the lower 2/3,
which meets the first cut.
When cutting to length on slopes, always stand on
the higher side of the trunk. To maintain complete
control at the end of the cut, reduce the cutting pres-
sure towards the end of the cut without loosening
your firm grip on the handles of the chain saw. Do not
let the chain come into contact with the floor.
Wait until the saw chain has stopped before moving
the chain saw. Always switch off the engine before
moving from tree to tree.
