Hold the saw tight with your thumb and fin-
gers grasping the grips and assume a posi-
tion with your body and arms that enables you
to withstand kickback forces. If suitable mea-
sures are taken, the operator will be able to
control the kickback forces. Never release the
chain saw.
Avoid any abnormal posture, and do not
saw anything above shoulder height. This will
avoid inadvertent contact with the tip of the
bar, and allow better control of the chain saw
in unexpected situations.
Always use replacement bars and saw chains
prescribed by the manufacturer. Incorrect re-
placement bars and saw chains can lead to
the chain breaking and/or to kickback.
Comply with the instructions of the manufac-
turer for sharpening and maintaining the saw
chain. Depth limiters set too low increase the
tendency to kickback.
Techniques for using the chain saw
Always comply with the safety instructions and
use the best cutting technique for the work to be
carried out according to the information and the
examples given in the instructions for use.
Recommendations for beginners
Before you fell a tree or prune a tree for the first
time, you should:
Have attended a special training course for
using this type of tool;
Have carefully read the safety instructions
and the instructions in this manual;
Practice on a tree stump or a log set up on a
stand in order to get the feel of the machine
and acquire suitable cutting techniques.
USING THE CHAIN SAWS FOR TREE
MAINTENANCE WITH A ROPE AND
CLIMBING HARNESS
This section describes the procedures that reduce
the risk of injury when using chain saws for tree
maintenance with the aid of a rope or climbing har-
ness. Even if this description could serve as a ba-
sic description for guidelines or training manuals,
it should not be viewed as a substitute for formal
training. The rules described in this appendix are
examples of good practice. National laws and re-
gulations must always be complied with.
General requirements for working at heights
The operators of chain saws for tree maintenance
using a rope or climbing harness must never work
40
alone. They should be supported by a worker on
the ground who is trained in the appropriate emer-
gency procedures.
The operators of chain saws for tree cutting
should be trained in the general climbing techni-
ques and working positions used in this type of
work and in the use of climbing harnesses, ropes,
belts with loops at the ends, carabiners and other
equipment for securely holding the operator and
the chain saw and assuming a safe working posi-
tion.
Preparing to use the chain saw on a tree
The chain saw should be che-
cked, refuelled, started and
warmed up by the worker on
the ground before it is swit-
ched off and handed to the
worker in the tree.
The chain saw should be atta-
ched to the climbing harness
of the user with a belt suitable
for this purpose.
Attach the belt to the eyelet on
the back of the chain saw (A).
Have suitable carabiners available for con-
necting the chain saw indirectly (i.e. with a
belt) or directly (i.e. to the eyelet of the chain
saw) to the climbing harness of the operator.
Ensure that the chain saw if securely connec-
ted when you reach it to the user.
Ensure that the chain saw is attached to the
climbing harness before taking it from the
hoisting device.
The possibility of attaching the chain saw directly
to the climbing harness reduces the risk of da-
mage to the equipment while the operator moves
around the tree. Always switch off the chain saw if
it is connected directly to the harness. The chain
saw should be connected to the recommended
loops on the climbing harness.
These may be found in the middle (front or rear)
or on the sides.
