WORKING TECHNIQUES

Limbing

When limbing thick branches you should use the same approach as for cutting.

Cut difﬁcult branches piece by piece.

Cutting

WARNING! Never attempt to cut logs

! while they are in a pile or when a couple 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

IMPORTANT! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task that you feel unsure of!

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.
