7.Cut only one log at a time.
8.Use extreme caution when reentering a previous cut.
9.Do not attempt to plunge cut if you are not experienced with these cutting techniques.
10.Be alert for shifting of the log or other forces that may cause the cut to close and pinch the saw chain.

Bow Guides
WARNING
Do not mount a bow guide on any STIHL chain saw. Any chain saw equipped with a bow guide is potentially very dangerous. The risk of kickback is increased with a bow guide because of the increased kickback contact area. Low kickback saw chain will not significantly reduce the risk of kickback injury when used on a bow guide.

WARNING
Use extreme caution when cutting small size brush and saplings which may easily catch the saw chain, be whipped towards you or pull you off balance.
To avoid pull-in
1.Always start a cut with the saw chain rotating at full speed and the bumper spike in contact with the wood.

Pushback occurs when the saw chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the saw chain may drive the chain saw rapidly straight back toward the operator and may cause loss of chain saw control, which, in turn, may cause serious or fatal injury. Pushback frequently occurs when the top of the bar is used for cutting.
To avoid pushback
1.Be alert to forces or situations that may cause material to pinch the top of the saw chain.
2.Do not cut more than one log at a time.
3.Do not twist the chain saw when withdrawing the bar from a plunge cut or underbuck cut because the saw chain can pinch.
