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.
5.11- Operators should never:
- cut with the kickback zone at the tip of the chainsaw guide bar,
- 'hold and cut' sections,
- Attempt to catch falling sections.
5.12- Freeing a trapped saw
If the saw should become trapped during cutting, operators should:
- switch off the saw and attach it securely to the tree inboard (i.e. towards the truck side) of the cut
or to a separate tool line;
