2.8.3. PREPARING TO USE THE CHAINSAW UP IN A TREE
The chainsaw should be fitted with a suitable strop for
attachment to the operator's harness.
1.
Secure the strop around the attachment point on the
rear of the chainsaw;
2.
provide suitable shackles to allow indirect (i.e. via
the strop) and direct attachment (i.e. at the attach-
ment point on the saw) of the saw to the operator's
harness;
3.
ensure the saw is securely attached when it is being
sent up to the operator;
4.
ensure the saw is secured to the harness before it is
disconnected from the means of ascent.
The ability to directly attach the saw to the harness re-
duces the risk of damage to equipment when moving
around the tree. Always switch the saw off when it is di-
rectly attached to the harness.
The saw should only be attached to the recommended
attachment points on the harness. These may be at mid-
point (front or rear) or at the sides. Where possible, attach
the saw to the centre rear mid-point to keep it clear of
climbing lines and to support its weight centrally down
the operator's spine.
When moving the saw from any one attachment point to
another, operators should ensure it is secured in the new
position before releasing it from the previous attachment
point.
2.8.4. USING CHAINSAW IN THE TREE
An analysis of accidents with these saws during tree service operations shows the primary cause as being inap-
propriate one-handed use of the saw. In the vast majority of accidents, operators fail to adopt a secure work position
that 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 likely to come into contact with climbing lines and the operator's
body (particularly the left hand and arm), and
• loss of control owing to an insecure work position and resulting in contact with the saw (unexpected movement
during operation of the saw).
