When moving the
chainsaw from one
attachment point to
another, the operator
must ensure that the
chainsaw is securely
tightened at the new
position before loosening
it from the previous
attachment point.
7.7.3. USE OF THE CHAINSAW IN THE TREE
Most of the accidents in the pruning height occur
because the operator fails to take a safe position
allowing him to use the saw with both hands. Using
the chainsaw with one hand involves:
- That the chainsaw is not fi rmly seized in event of a
kickback.
- That is more diffi cult to handle the chainsaw so it
is more likely that it comes into contact with the
ascent lines, security and attachment cords, and
the body of the operator (particularly with the left
hand and arm).
- Increases the loss of control due to an unsafe
working position that results in the contact of the
moving chainsaw with the branch to be cut.
As a general rule you should get a fi rm footing in
B
order to use the machine with both hands. In order
to do so, the operator should seek a safe position in
which to work with the chainsaw at hip level (when
cutting horizontal sections) or at the solar plexus level
A
(when cutting vertical sections).
If the operator is working near
vertical stems where there
are small lateral forces in the
working position, then a good
positioning of the feet is enough
to get a fi rm footing. However,
as the operator moves away
from the vertical stem he will
need to step to eliminate or
counteract the lateral forces,
thus modifying the main ascent
route through an additional
anchor or through the use of an
adjustable safety cord hooked from the harness up to
an additional anchor point.
The operator can also get a good positioning of the
feet in the working position by means of a temporary
abutment formed from a sling without end.
7.7.3.4. USING THE CHAINSAW WITH ONE HAND
Only when it is impossible
for the operator to cut
from a stable position
using both hands, you
can maintain a working
position by leaning on one
hand. Use the saw with
the fully outstretched arm
and make sure the arm is
at a right angle to the line of the body so you can cut
with one hand.
