the engine at full speed. If the chain is slow to stop or does not stop, replace the brake band and
clutch drum before use.
- It is extremely important that the chain brake be checked for proper operation before each use and
that the chain be sharp in order to maintain the kickback safety level of this saw. Removal of the
safety devices, inadequate maintenance, or incorrect replacement of the bar or chain may increase
the risk of serious personal injury due to kickback.
5.4- Working from a rope and harness
(With chain-saws intended for tree service)
This chapter sets out working practices to reduce the risk of injury from tree service chainsaws
when working at height from a rope and harness.
While it may form the basis of guidance and training literature, it should not be regarded as a
substitute for formal training.
5.5- General requirements working at height
Operators of tree service chainsaws working at height from a rope and harness should never work
alone. A competent ground worker trained in appropriate emergency procedures should assist
them.
Operators of tree service chainsaws for this work should be trained in general safe climbing and
work positioning techniques and shall be properly equipped with harnesses, ropes, strops,
karabiners and other equipment for maintaining secure and safe working positions for both
themselves and the saw.
5.6- Preparing to use the saw in the tree
The chainsaw should be checked, fuelled, started and warmed up by the ground worker before it is
sent up to the operator in the tree. The chainsaw should be fitted with a suitable strop for attaching
to the operator's harness:
a) Choke the strop around the attachment point on the rear of the saw (A);
b) Provide suitable karabiners to allow indirect (i.e. via the strop) and direct attachment (i.e. at the
attachment point on the saw) of saw to the operator's harness;
c) Ensure the saw is securely attached when it sent up to the operator;
d) Ensure the saw it secured to the harness before disconnected from the means of ascent.
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 attaching the saw to centre rear
mid-point will keep it clear of climbing lines and support its weight centrally down the operator's
spine.
When moving the saw from any attachment point to another, operators should ensure it is secured
in the new position before releasing it from the previous attachment point.
