SAFETY INSTRUCTIONS

There are ﬁve important factors you should consider before making a cut:

1 Make sure the cutting equipment will not jam in the cut.

2 Make sure the object you are cutting will not split.

3Make sure the chain will not strike the ground or any other object during or after cutting.

4 Is there a risk of kickback?

5Do the conditions and surrounding terrain affect how safely you can stand and move about?

Two factors decide whether the chain will jam or the object that you are cutting will split: the ﬁrst is how the object is supported before and after cutting, and the second is whether it is in tension.

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 commonest 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.
