• The saw chain must not touch the ground
or any object while sawing through the
material or thereafter.
• Do not saw with the rail tip.
• Please observe the precautionary meas-
ures to protect against kickback (Causes
and Operator Prevention of Kickback,
p. 35)
• If possible, support the pruning saw with
the claw stop (14) when delimbing.
• Make sure that the chainsaw can swing
through at the end of the cut due to its
own weight. The chainsaw will no longer
be supported in the cut. Counteract this
accordingly.
• Always switch off the chainsaw engine
before moving from tree to tree.
Limbing work in sections
Shorten long or thick branches before mak-
ing the final separating cut. This prevents the
saw chain from jamming.
Working in the tree with rope
climbing technique
This section describes working methods to
reduce the risk of injury when using chain-
saws for tree care when working at height
using rope climbing techniques. It can serve
as a basis for instructions and training doc-
uments, but is no substitute for proper train-
ing. The recommendations in this appendix
are just one example of best practice.
Stricter national or other regulations may ap-
ply.
This section explains
• general information to be observed be-
fore using a tree care chainsaw for work
at height with rope climbing technology,
• how to prepare a tree care chainsaw for
use with rope climbing technology and
• how to use a pruning chainsaw to prune
and cut up trees, including safe working
posture for two-handed use, how to start
the chainsaw, how to cut with the chain-
saw and how to free a jammed chainsaw.
This section does not deal with control tech-
niques for cut branches and twigs or the
points on safe use already covered.
General recommendations
• The operator of a pruning saw working
at height with rope climbing technology
should never work alone. A worker on
the ground who is trained in appropriate
40
emergency procedures should be present
to assist.
• The operator should be trained in safe
climbing and working positions and have
appropriate equipment such as harness,
ropes, harnesses, carabiners and other
equipment to ensure a safe working posi-
tion for themselves and the chainsaw.
Preparing the chainsaw for use
• The chainsaw should be checked, started
and switched off again by the worker on
the ground before it is passed to the op-
erator in the tree.
• The chainsaw requires a suitable sling
for attachment to the operator's climbing
harness (Fig. B.①).
• The sling must be attached to the re-
taining eyelet on the rear of the chain-
saw.
• Suitable snap hooks must be provided
to attach the chainsaw indirectly (i.e.
via the sling) and directly (i.e. to the
retaining eye on the chainsaw) to the
climbing harness.
• Before passing the chainsaw on to
the operator, ensure that it is securely
fastened.
• Before removing the chainsaw from
the climbing equipment, make sure
that it is attached to the climbing har-
ness.
• Attaching the chainsaw directly to the
climbing harness reduces the risk of dam-
age to the equipment when moving in the
tree. However, make sure that the chain-
saw is always switched off.
• The chainsaw should only be attached to
the recommended attachment points of
the climbing harness, which are located in
the centre (front or back) or on the sides.
The chainsaw should ideally be fixed at
the centre back to keep it away from the
climbing ropes and to keep the weight
central to the operator's spine (Fig. B.②).
• When moving the chainsaw from one lift-
ing eye to another, the operator must en-
sure that it is secured in the new position
before releasing it from the previous lifting
eye.
Using the pruning saw in the tree
• The chain brake should always be applied
before a running chainsaw is lowered
from the tree.
