WORKING TECHNIQUES

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.

Felling direction

The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely. The main thing to avoid is that the falling tree top should get jammed in another tree. Taking down a ”jammed” tree top is very dangerous (see point 4 in this section).

Once you have decided which way you want the top of the tree to fall you must assess which way the top of the tree would fall naturally.

Several factors affect this:

Lean of the tree

Bend

Wind direction

Arrangement of branches
