Felling technique for tree tops

WORKING TECHNIQUES

In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom.You need to support the object so that it will not trap the chain or split during cutting.

WARNING! If the chain jams in the cut:

! stop the engine! Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw.

The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw.

Cutting

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.

Limbing

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

Cut difﬁcult branches piece by piece.

Felling technique for tree tops

WARNING! It takes a lot of experience to

! fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task beyond your experience level!

Safe distance

During tree maintenance work above ground level, the working area must always be secured and marked out with signs, tape or the like. The safe distance between the top of the tree that is to be felled and the nearest workplace must be at least 2 1/2 times the height of the tree. Make sure that no-one else is in this risk zone before or during felling.
