3.2- Kickback safety precautions for chain saw users
WARNING
- Kickback may occur when the nose or tip of the guide bar touches an object, or
when the wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a lightning fast reverse reaction, kicking the
guide bar up and back towards the operator.
Pinching the saw chain along the top of the guide bar may push the guide bar
rapidly back towards the operator.
Either of these reactions may cause you to lose control of the saw, which could
result in serious personal injury.
- Do not rely exclusively on the safety devices built into your saw.
As a chain saw user you should take several steps to keep cutting jobs free from
accident or injury.
(1) With a basic understanding of kickback you can reduce or eliminate the
element of surprise.
Sudden surprise contributes to accidents.
(2) Keep a good grip on the saw with both hands, the right hand on the rear handle,
and the left hand on the front handle, when the engine is running.
Use a firm grip with thumbs and fingers encircling the chain saw handles.
A firm grip will help you reduce kickback and maintain control of the saw.
(3) Make certain that the area in which you are cutting is free from obstructions.
Do not let the nose of the guide bar contact a log, branch, or any other obstruction
which could be hit while you are operating the saw.
(4) Cut at high engine speeds.
(5) Do not overreach or cut above shoulder height.
Keep proper footing and balance at all times.
(6) Follow the manufacturer's sharpening and maintenance instructions for the
saw chain.
(7) Only use replacement bars and chains specified by the manufacturer or the
equivalent.
3.3- 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.
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 properly equipped with harnesses, ropes, strops, karabiners
and other equipment for maintaining secure and safe working positions for both themselves and the
saw.
Preparing to use the saw in the tree
The chainsaw should 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
