Branch Removal; Working With Wood That Is Under Tension - Scheppach 5910114903 Originalbetriebsanleitung

• If the appliance accidentally comes into contact
with a solid object, turn off the engine immediately
and inspect the appliance for damage.
• Service the appliance carefully. Check for misalign-
ment or binding of moving parts, breakage of parts
and any other damage that may impair the tool's
operation. If damaged, have the appliance repaired
before use. Many accidents are caused by poorly
maintained tools.
• Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Have the appliance checked by qualified special-
ists. Use only the replacement parts recommended
by the manufacturer.
10.2 Creating the notch cut
Note
The kerf determines the direction that the tree will fall
in.
Place the kerf at right angles to the fall direction.
Saw as close the ground as possible.
Support the chainsaw using the bumper spike (15).
10.2.1 Determining the felling direction - with
marks on the device (fig. G)
The chainsaw is equipped with felling marks (35)
which aid you with the direction of the chainsaw.
Place the chainsaw against the trunk. The felling
marks (35) show you the probable felling direction of
the tree.
10.2.2 Creating the notch cut (fig. H)
• Start with the first kerf cut A. The depth of the kerf
should be about 1/4 of the diameter of the tree and
at an angle of 45°–60°.
10.2.3 Checking the felling direction (fig. I)
Place the chainsaw with the guide rail (16) at the bot-
tom of the notch cut.
The felling marks (35) show the probable felling di-
rection.
If necessary, recut the notch cut accordingly.
10.3 Carrying out the felling cut (fig. H)
• Make the felling cut B around 2–3 centimetres high-
er than the horizontal kerf cut A. Ensure that the
felling cut B is perfectly horizontal.
• Leave around 1/10 of the tree diameter, the hinge
C, in front of the felling cut B. The hinge C guides
the tree to the ground – like a door hinge – and
prevents premature falling.
m WARNING
Risk of accidents!
Do not saw the hinge C at the same time as the felling
cut B, otherwise the tree could fall in an unexpected
direction!
Be prepared that the tree can slip uncontrollably
when it falls onto the cut.
Be prepared that the tree can jump uncontrollably in
an unexpected direction when it hits the ground
• To prevent the chainsaw from getting caught in the
felling cut B, push aluminium or plastic wedges into
the cut B. Do not use iron wedges.
m CAUTION
Property damage!
Make sure that the wedge does not come into contact
with the saw chain (17). This can severely damage it.

10.4 Branch removal

• Be aware of the danger of branches flying back.
• Do not stand on the trunk while removing branches.
• Do not saw with the tip of the blade.
• Never saw several branches at once.
• Support the chainsaw where possible using the
bumper spike (15).
• Make sure that the chainsaw cannot swing through
at the end of the cut due to its own weight. If it is no
longer supported in the cut, hold something appro-
priate against it.
• Make sure you have firm, stable and secure footing
when de-branching.
10.4.1 Saw in sections
Trim long or thick branches before you make the final
cut (see fig. N). Otherwise, the saw chain (17) can
easily catch.
11. Working with wood
that is under tension
It is important to carry out the working steps in the
correct order when working with wood that is under
tension. Otherwise the saw chain (17) could jam or
there could be a kickback.
Wood under pressure should always be worked first
on the 'push' side. Only then can a separating cut be
made on the 'pull' side.
This helps to prevent the saw chain (17) from jam-
ming.
