A

001BA037 KN

Pull-in occurs when the chain on the bottom of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain pulls the saw forward and may cause the operator to lose control.

Pull-in frequently occurs when the bumper spike of the saw is not held securely against the tree or limb and when the chain is not rotating at full speed before it contacts the wood.

Warning!

Use extreme caution when cutting small size brush and saplings which may easily catch the chain, be whipped towards you or pull you off balance.

To avoid pull-in

1.Always start a cut with the chain rotating at full speed and the bumper spike in contact with the wood.

2.The risk of pull-in may also be reduced by using wedges to open the kerf or cut.

B

001BA038 KN

Pushback occurs when the 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 chain may drive the saw rapidely straight back toward the operator and may cause loss of saw control. 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 chain.

2.Do not cut more than one log at a time.

3.Do not twist the saw when withdrawing the bar from a plunge cut or underbuck cut because the chain can pinch.
