of the log. The compression side of the log is where the
pressure of the log's weight is concentrated.
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 kick-
back. 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 particu-
larly applies to bent or loaded branches. Avoid com-
ing 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 safely 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 method
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
second 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 appro-
priate emergency procedures should assist them.
Operators of tree service chainsaws for this work
should be trained in general safe climbing and work
positioning techniques and shall properly equipped
with harnesses, ropes, strops, karabiners and other
equipment for maintaining secure and safe working
positions 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.
Thanks to the ability to attach the chainsaw directly
to the harness, the risk of damage to the equipment
when moving around the tree is reduced. The sup-
ply to the chainsaw must always be disconnected if
it is attached directly to the harness. The saw should
only be attached to the recommended attachment
points on the harness. These may be at mid-point
(front or rear) or at the sides. Where possible attach-
ing the saw to centre rear mid-point will keep it clear
of climbing lines and support its weight centrally
down the operator's spine (Fig.N). When moving the
saw from any attachment point to another, operators
should ensure it is secured in the new position be-
fore releasing it from the previous attachment point.
