5.7- Using the chainsaw in the tree
An analysis of accidents with these saws during tree service operations shows the primary cause as
being inappropriate one-handed use of the saw.
In the vast majority of accidents, operators fail to adopt a secure work position which allows them
to hold both handles of the saw.
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;
