WORKING TECHNIQUES

stem, they will need to take steps to remove or counteract the increasing lateral forces by, for example, a re-direct of the main line via a supplementary anchor point or using an adjustable strop direct from the harness to a supplementary anchor point.

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:

1on the left side hold the saw with the left hand on the front handle and thrust the saw away from the body while holding the pull starter cord in the other hand.

2on 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 lowering 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 never use a chain saw onehanded.

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.

•Cut in the tree when he/she is only secured with one rope, always use 2 secured lines.

•check condition of harness, belt and ropes at regular frequent intervals.

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 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 (toward the tips of the branch), in order to prevent the saw being taken with the section and further complicating the situation.

Basic cutting technique

General

•Always use full throttle when cutting!

•Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage).

•Cutting from above = Cutting with a pulling chain.

•Cutting from below = Cutting with pushing chain.

Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback.

Terms

Cutting = General term for cutting through wood.

Limbing = Cutting branches off a felled tree.

Splitting = When the object you are cutting breaks off before the cut is complete.

There are five important factors you should consider before making a cut:

1Make sure the cutting equipment will not jam in the cut.

2Make sure the object you are cutting will not split.

3Make sure the chain will not strike the ground or any other object during or after cutting.

4 Is there a risk of kickback?

5Do the conditions and surrounding terrain affect how safely you can stand and move about?

Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension.
