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;
- pull the saw from the kerf whilst lifting the branch as necessary;
- if necessary, use a handsaw or second chain saw to release the trapped saw by cutting a minimum of
30cm away from the trapped saw.
Whether a handsaw or a chainsaw is used to free a stuck saw, the release cuts should always be
outboard (toward the tips of the branch), in order to prevent the saw being taken with the section and
further complicating the situation.
5.13- Bucking and Limbing
WARNING - Always ensure your foothold. Do not stand on the log.
- Be alert to the rolling over of a cut log. Especially when working on a slope,
stand on the uphill side of the log.
- Follow the instructions in "For Safe Operation" to avoid kickback of the saw.
Before starting work, check the direction of bending force inside the log to be cut.
Always finish cutting from the opposite side of the bending direction to prevent the guide bar from
being caught in the cut.
(a) Cutting the limbs of Fallen Tree
First check to which side the limb is bent.
Then make the initial cut from the bent side and finish by sawing from
the opposite side.
WARNING - Be alert to the springing back of a cut limb.
(b) Pruning of Standing Tree
Cut up from the bottom, finish down from the top.
WARNING - Do not use an unstable foothold or ladder.
- Do not overreach.
- Do not cut above shoulder height.
- Always use both your hands to hold the saw.
