11.1.2 Working on tensioned wood
It is essential to follow the correct sequence when
working on wood that is tensioned. Otherwise the
saw chain (1) may jam or kick-back may occur.
Tensioned wood must always be cut on the com-
pressed side first. Only then perform the separating
cut using the opposite side. (Fig. 24)
This prevents the saw chain (1) from jamming.
m ATTENTION
Property damage!
Lying wood must not touch the floor on the underside
of the cutting point, otherwise the saw chain (1) may
be damaged.
Recoil
• If the saw chain (1) jams on the top edge of the
guide rail (2), the chainsaw can jerk back suddenly
in the direction of the operator in an uncontrolled
manner.
Dragging
• If the saw chain (1) jams on the lower edge of the
guide rail (2), the chainsaw can jerk forward sud-
denly away from the operator in an uncontrolled
manner.
Safe work
• Keep the device in good working order to prevent
injuries.
• After dropping the device, check for significant
damage or defects.
• Do not use the device whilst standing on a ladder or
in an unsafe position.
• Do not be tempted to make a rash cut. This could
endanger yourself and others.
• Change your working position regularly. Prolonged
use of the device can lead to vibration-induced
circulatory disorders of the hands. However, you
can extend the duration of use by wearing suitable
gloves or taking regular breaks. Be aware that per-
sonal predisposition to poor circulation, low outside
temperatures or large gripping forces when work-
ing reduce the duration of use.
11.2 Wooden branch is bent downwards
1. First saw relief cut 1 (approx. 1/3 of the branch
diameter) on the compressed side.
2. Then make cut 2 (approx. 2/3 of the branch diam-
eter) on the tensioned side.
11.3 Wooden branch is bent upwards
1. First saw relief cut 1 (approx. 1/3 of the branch
diameter) on the compressed side.
2. Then make cut 2 (approx. 2/3 of the branch diam-
eter) on the tensioned side.

11.4 Tree care saw use for tree pruning in combi-
nation with rope climbing technique
This appendix presents appropriate working practices
to reduce the danger of injury from the use of chain-
saws for tree pruning when working at height with a
rope and carrying strap. Although it can serve as a
guide and training reading, it should not be considered
a substitute for formal training. The guidance given in
this appendix serves only as an example of good prac-
tice.
National or other regulations that may be stricter may
apply.
The user of a chainsaw for tree pruning working at
height with a rope and carrying strap should never
work alone. A ground worker trained in appropriate
emergency procedures should be present to assist.
The user should be trained in general safe climb-
ing and work positioning techniques and should be
equipped with carrying strap, rope, slings, carabiners
and other equipment for obtaining safe and correct
working positions for both themselves and the saw.
National laws and regulations must always be strictly
observed.
This appendix does not cover techniques for con-
trolling the branches and twigs cut by the chainsaw,
nor does it include the points already covered on safe
use.
11.4.1 General requirements
The user of a chainsaw for tree pruning working at
height with a rope and carrying strap should never
work alone. A ground worker trained in appropriate
emergency procedures should be present to assist.
The user should be trained in general safe climb-
ing and work positioning techniques and should be
equipped with carrying strap, rope, slings, carabiners
and other equipment for obtaining safe and correct
working positions for both themselves and the saw.
11.4.2 Preparation before using the tree pruning
saw on the tree
The chainsaw should be checked, fuelled, started and
warmed up by the ground worker and then switched
off before being hoisted up to the user in the tree.
The chainsaw should be fitted with a suitable sling
so that it can be attached to the user's carrying strap
(Fig. 13):
• Secure the sling to the suspension device (19) lo-
cated on the back of the saw (Fig. 12).
• Suitable carabiners shall be provided to allow in-
direct (i.e. through the sling) and direct (i.e. to the
suspension device (19) of the chainsaw) attach-
ment of the saw to the user's carrying strap.
• Ensure that the chainsaw is securely fastened when
it is pulled up to the user (Fig. 14).
• Ensure that the chainsaw is attached to the carry-
ing strap before releasing it from the lifting cable.
