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.

IMPORTANT! 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.

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.
