Using the chain saws for tree maintenance with a rope and climbing harness
If possible, connect the chain
saw to the rear middle loop to
prevent it from hindering the
climbing ropes and to ensure
that its weight is centred at
base of the spine of the ope-
rator.
When transferring the chain
saw from one loop to another,
the operator must ensure that
it is attached to the new po-
sition before detaching it from
the previous loop.
Using a chain saw in a tree
An analysis of the accidents with these chain
saws during tree maintenance work shows that
the main cause of accidents is the unintended use
of the chain saw with only one hand. In most ac-
cidents, the operators do not try to assume a safe
working position that enables them to grasp the
chain saw with both hands.
This causes an increased risk of injury because:
The operator does not have a firm hold on the
chain saw in case of a kickback.
The operator does not have control over the
chain saw, which increases the possibility of
contact between the chain saw and the clim-
bing ropes and with the body of the operator
(especially with the left arm and left hand),
It is possible to lose control because the ope-
rator does not assume a safe working posi-
tion, which can lead to contact with the chain
saw (unintentional movement while the chain
saw is running).
Safe working position for two-hand operation
To enable the operator to use the chain saw with
both hands, it must be a general rule to assume
a safe working position when operating the chain
saw.
At hip height, when cutting horizontally
At solar plexus height, when cutting vertically
When the operator is working close to vertical
trunks, with low thrust forces on the working posi-
tion, a good support may be necessary to main-
tain a safe working position.

When the operator moves away
from the trunk, however, an at-
tempt must be made to cancel out
or neutralise the growing thrust
forces, such as by changing the
direction of the main rope with an
additional anchor point or by con-
necting an adjustable belt directly
to the harness at an additional
loop.
A secure hold in the working po-
sition can be achieved by using a
stirrup that is temporarily fashio-
ned from a loop into which the
foot is placed.
Starting the chain saw in a tree
When starting the chain saw in a tree, the opera-
tor:
Must apply the chain brake before starting the
chain saw
Hold the chain saw on the left or right side of
the body before starting the chain saw, i.e.:
On the left side, grasping the chain saw
with the left hand at the front grip and
away from the body, while pulling the
starter cable with the right hand, or
On the right side, grasping the chain saw
with the right hand at the front grip and
away from the body, while pulling the
starter cable with the left hand, or
The chain brake must always be applied before
letting the running chain saw hang from the belt.
Before performing critical cuts, the operator must
always check if the chain saw has enough fuel.
Using the chain saw with only one hand
The chain saws for tree maintenance should not
be operated using only one hand if the operator is
not in a safe working position or the chain saw is
being using to cut twigs at the ends of branches
instead of a hand saw.
The chain saws for tree maintenance are only per-
mitted to be used with one hand if:
