Working With Tree Service Chain- Saws From A Rope And Harness - Scheppach CSP2540 Manual De Instrucciones

GB
Log division without supports (Fig. F)
Using topping (Pos. 1), saw 1/3 of the way into the
tree.
Turn the log around and make a second top cut (Pos.
2).
When sawing on the compression side, make sure
the saw does not get jammed. See Figure for cuts in
logs on the compression side.
Log division with log or support (Fig. G-H)
Always remember to make the first cut (Pos. 1) on the
loaded side of the log.
Cut 1/3 into the log for this.
Make a second cut (Pos. 2).
Trimming and pruning
m CAUTION
Always be careful and protect yourself from kickback.
Never let the moving chain at the tip of the chain guide
come in contact with other branches or objects during
trimming or cutting branches. Such contact can lead
to serious injuries.
m CAUTION
Never climb into the tree for trimming or pruning. Do
not stand on ladders, platforms etc. You could lose
your balance and control of the device.
Important notices
Work slowly and hold on to the saw with both hands.
Ensure a secure standing position and balance.
Beware of recoiling parts of the tree. Practise ex-
treme caution when cutting small parts of the tree.
Flexible material can get caught in the saw-chain and
be ejected in your direction or make you lose your
balance.
Beware of recoiling parts of the tree. This particularly
applies to bent or loaded branches. Avoid coming in
contact with the branch or the saw when the tension
on the wood is released.
Keep your working area clear. Clear the path of
branches so you do not trip over them.
Trimming
Do not start trimming the tree before it has been
felled. Only then can you carry out the trimming safe-
ly and properly.
Leave larger branches underneath the felled tree and
use them as a support while you continue working.
Start at the foot of the felled tree and work your way
up to the top. Remove smaller parts of the tree with
one cut.
Make sure that the tree is always between you and
the saw.

Remove larger, supporting branches using the meth-
od from Section „Log division without support".
Always remove small freely suspended parts of the
tree with a top cut. They may fall into the saw or trap
it if you use an undercut.
Pruning (Fig. K)
m CAUTION
Prune branches only at or below shoulder height.
Never cut branches above shoulder height. Leave
that kind of work to a professional.
For the first cut (Pos. 1), cut 1/3 of the way into the
lower part of the branch.
Then cut all the way through the branch with the sec-
ond cut (Pos. 2). The third cut (Pos. 3) is a top cut
with which you separate the branch from the trunk at
a distance of 2.5 to 5cm.
WORKING WITH TREE SERVICE CHAIN-
SAWS FROM A ROPE AND HARNESS
This chapter sets out working practices to reduce
the risk of injury from tree service chainsaws when
working at height from a rope and harness. While it
may form the basis of guidance and training litera-
ture, it should not be regarded as a substitute for for-
mal training. The directives contained in this annex
are only practical examples. National laws and regu-
lations must always be strictly observed.
General requirements working at height
Operators of tree service chainsaws working at height
from a rope and harness should never work alone.
A competent ground worker trained in appropriate
emergency procedures should assist them. Opera-
tors of tree service chainsaws for this work should
be trained in general safe climbing and work position-
ing techniques and shall properly equipped with har-
nesses, ropes, strops, karabiners and other equip-
ment for maintaining secure and safe working posi-
tions for both themselves and the saw.
Preparing to use the saw in the tree
The chainsaw should checked, fuelled, started and
warmed up by the ground worker before it is sent up
to the operator in the tree.
The chainsaw should be fitted with a suitable strop for
attaching to the operator's harness
a) choke the strop around the attachment point on
the rear of the saw (R1, Fig.R);
b) provide suitable karabiners to allow indirect (i.e.
via the strop) and direct attachment (i.e. at the at-
tachment point on the saw) of saw to the opera-
tors harness;
c) c) ensure the saw is securely attached when it is
being sent up to the operator;
d) ensure the saw it secured to the harness before it
is disconnected from the means of ascent.
