WORKING TECHNIQUES

Limbing

When limbing thick branches you should use the same

approach as for cutting.

Cut difficult branches piece by piece.

Cutting

| _ while they are in a pi!e or when a coupie|

| _ of logs are lying together. Such |

| procedures drastically increase the risk |

| of kickback which can result in a serious |

or fatal injury.

if you have a pile of logs, each log you attempt to cut

should be removed from the pile, placed on a saw horse

or runners and cut individually.

Remove the cut pieces from the cutting area. By leaving

them in the cutting area, you increase the risk for

inadvertently getting a kickback, as well as increasing the

risk of losing your balance while working.

The log is lying on the ground. There is little risk of the

chain jamming or the object splitting. However there is a

risk that the chain will touch the ground when you finish

the cut.

Cut all the way through the log from above. Avoid letting

the chain touch the ground as you finish the cut. Maintain

full throttle but be prepared for what might happen.

If it is possible (can you turn the log?) stop cutting about

2/3 of the way through the log.

Turn the log and finish the cut from the opposite side.

The log is supported at one end. There is a high risk

that it will split.

Start by cutting from below (about 1/3 of the way through).

Finish by cutting from above so that the two cuts meet.

The log is supported at both ends. There is a high risk

that the chain will jam.

Start by cutting from above (about 1/3 of the way through).

Finish by cutting from below so that the two cuts meet.

Tree felling technique

Safe distance

The safe distance between a tree that is to be felled and

anyone else working nearby is at least 2 1/2 tree lengths.

Make sure that no-one else is in this "risk zone" before or

during felling.
