Zenoah GZ3500T Starting the saw in the tree, One-hand use of the chainsaw, Freeing a trapped saw

Gaining a good footing at the working position can be assisted by use of a temporary foot stirrup created from an endless sling.

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 low- ering a running saw onto its strop.

Operators should always check the saw has sufficient fuel before undertaking critical cuts.

One-hand use of the chainsaw

Operators should not use tree service chainsaws one- handed in place of unstable work positioning or in pref- erence 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.

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.

Freeing a trapped saw

If the saw should become trapped during cutting, op- erators 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 30 cm 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 (to- ward the tips of the branch), in order to prevent the saw being taken with the section and further complicating the situation.
