Branch Removal; Working With Wood That Is Under Tension - Parkside PBKS 53 A1 Bedienungs- Und Sicherheitshinweise Originalbetriebsanleitung

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 bottom of
the notch cut.
The felling marks (35) show the probable felling direction.
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 higher than
the horizontal kerf cut A. Ensure that the felling cut B is per-
fectly 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 unex-
pected 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 sup-
ported in the cut, hold something appropriate 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 jamming.
m CAUTION
Property damage!
Horizontal lumber may not touch the ground on the underside
of the cut, otherwise the saw chain (17) could be damaged.
Kickback (fig. J)
• If the saw chain (17) jams on the upper edge of the guide
rail (16), the chainsaw can kick back violently towards the
operator.
Drawing in (fig. K)
• If the saw chain (17) jams on the lower edge of the guide
rail (16) , the rail can jerk violently away from the operator.
Working safely
• Keep the appliance in good working order to prevent injury.
• If the appliance has been dropped, check for significant
damage or defects.
• Do not use the appliance while standing on a ladder or with
unsteady footing.
• Do not be tempted into making a poorly considered cut. You
could endanger yourself and others.
• Change your working position regularly. Using the appli-
ance for a long time can lead to vibration-related circulation
disorders of the hands. You can extend the usage duration
by using appropriate gloves or by taking regular breaks.
Note that any personal predisposition to poor blood circu-
lation, low external temperatures or large prehensile forces
can reduce the usage period.
11.1 Trunk is bent downwards
• Start by making a relief cut 1 (approx. 1/3 of the trunk diam-
eter) on the push side (see fig. L).
• Then make a separating cut 2 (approx. 2/3 of the trunk di-
ameter) on the pull side (see fig. L).
11.2 Trunk is bent upwards
• Start by making a relief cut 1 (approx. 1/3 of the trunk diam-
eter) on the push side (see fig. L).
• Then make a separating cut 2 (approx. 2/3 of the trunk di-
ameter) on the pull side (see fig. L).
