• Change your working position regularly. Prolonged use of
the device can lead to vibration-induced circulatory disor-
ders of the hands. However, you can extend the duration
of use by wearing suitable gloves or taking regular breaks.
Be aware that personal predisposition to poor circulation,
low outside temperatures or large gripping forces when
working reduce the duration of use.
11.2 Wooden branch is bent downwards
1. First saw relief cut 1 (approx. 1/3 of the branch diam-
eter) on the compressed side.
2. Then make cut 2 (approx. 2/3 of the branch diameter)
on the tensioned side.
11.3 Wooden branch is bent upwards
1. First saw relief cut 1 (approx. 1/3 of the branch diam-
eter) on the compressed side.
2. Then make cut 2 (approx. 2/3 of the branch diameter)
on the tensioned side.
11.4 Tree care saw use for tree pruning in
combination with rope climbing technique
This appendix presents appropriate working practices to re-
duce the danger of injury from the use of chainsaws 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 practice.
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 climbing and work
positioning techniques and should be equipped with carry-
ing strap, rope, slings, carabiners and other equipment for
obtaining safe and correct working positions for both them-
selves and the saw.
National laws and regulations must always be strictly ob-
served.
This appendix does not cover techniques for controlling 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 climbing and work
positioning techniques and should be equipped with carry-
ing strap, rope, slings, carabiners and other equipment for
obtaining safe and correct working positions for both them-
selves 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 be-
fore 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) located on
the back of the saw (Fig. 12).
• Suitable carabiners shall be provided to allow indirect (i.e.
through the sling) and direct (i.e. to the suspension device
(19) of the chainsaw) attachment 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 carrying strap
before releasing it from the lifting cable.
The possibility of attaching the chainsaw directly to the car-
rying strap reduces the danger of damaging the equipment
when moving it in the tree. The chainsaw should always be
switched off when it is attached directly to the carrying strap.
The chainsaw should only be attached to the recommended
suspension devices on the carrying strap. These may be in
the middle (front or back) or on the sides. Wherever possible,
attach the chainsaw to the centred rear centre of the carrying
strap to keep it away from climbing ropes and to support the
weight centrally under the user's spine.
If the chainsaw is moved from any suspension device to an-
other, users should ensure that the chainsaw is secured in the
new position before it is released from the previous suspen-
sion device.
