SAFETY INSTRUCTIONS

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.

Tree felling technique

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 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 21/2 tree lengths. 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 on ground where you can stand and move about safely.The main point to avoid is letting the tree fall onto another tree. See instructions under the heading Freeing a tree that has fallen badly.

Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally.

Several factors affect this:

• Lean of the tree

• Bend

• Wind direction
