This results in an increased risk of injury due to:
- not having a firm grip on the saw if it kicks back;
- a lack of control of the saw such that it is more liable to contact climbing lines and operators body
(particularly the left hand and arm)
- losing control from insecure work position resulting in contact with the saw (unexpected
movement during operation of the saw)
5.8- Securing the work position for two-handed use
To allow the operator to hold the saw with both hands, they should as general rule, aim for secure
work position where they are operating the saw at:
- hip level when cutting horizontal sections;
and
- solar plexus level when cutting vertical sections.
Where the operator is working close into vertical
stems with a low lateral force on their work position,
then a good footing may be all that is needed to
maintain a secure work position.
However as operators move away from the stem, they
will need to take steps to remove or counteract the
increasing lateral forces by, for example, a re-direct of
the main line via a supplementary anchor point or
using an adjustable strop direct from the harness to a
supplementary anchor point.
Gaining a good footing at the working position can be assisted by use of a temporary foot stirrup
created from an endless sling
5.9- Starting the saw in the tree
When starting the saw in the tree, the operator should:
a) apply the chain brake before starting;
b) hold saw on either the left or right of the body when starting:
1) on the left side hold the saw with either the left hand on the front handle or the right hand on
the rear handle and thrust the saw away from the body while holding the pull starter cord in the
other hand;
2) on the right side, hold the saw with the right hand on either handle and thrust the saw away
from the body while holding the pull starter cord in the left hand.
The chain brake should always be engaged before lowering a running saw onto its strop.
Operators should always check the saw has sufficient fuel before undertaking critical cuts.
5.10- One-hand use of the chainsaw
Operators should not use tree service chainsaws one-handed in
places of unstable work positioning or in preference to a handsaw
when cutting small diameter wood at the branch tips.
Tree service chainsaws should only be used one-handed where:
- the operator cannot gain a work position enabling two-handed use;
and
- they need to support their working position with one hand; and
- the saw is being used at full stretch, at right angles to and out of line
with the operator's body.
