Avoiding Kickback - Your Equipment

IMPORTANT!

This equipment is for extra protection. It cannot fully prevent kickbacks - only minimize them. Never rely entirely on these safety devices for your protection. Rely instead on safe working techniques.

As explained previously, kickback can be avoided by using safe cutting techniques, in which you consistently avoid cutting with the tip of the guide bar.

However, certain items on your electric chain saw are also designed to minimize the kickback itself or potential injuries, should a kickback occur.

Low-Kickback Chain

Modern saw chains are designed to reduce the force of a kickback. Your Operator’s Manual lists low-kickback saw chains that have been tested and selected for your saw.

Small Nose Radius Bar

The smaller the bar-nose radius, the smaller the kickback zone and the less likely it is that a severe kickback will occur. Your Technical Manual lists small nose radius bars available for your saw.

IMPORTANT!

To minimize the risk of kickback, you should always:

Use small nose radius bar and low-kickback saw chain.

Check and adjust chain tension.

Maintain cutter sharpness and correct depth gauge height.

Replace worn or damaged bar and chain with approved replacement combinations.

CAUTION!

The chain’s kickback reduction features will provide their intended protection only if the chain is sharpened and maintained according to the manufacturer’s instructions. As a cutter is filed away when sharpened repeatedly, it gradually becomes increasingly aggressive. Towards the end of its service life, it is more prone to kickback than when it was new.

Your saw chain has been designed to reduce the likelihood of kickback, If the chain is not sharpened according to the manufacturer’s directions, some of the chain’s kickback-reduction features may deteriorate, making the chain more dangerouse to use. Always follow the chain manufacturer’s sharpening instructions.

When it is time to replace your saw chain, replace it with a low-kickback cain. Follow our recommendations in the Operator’s Manual or your dealer’s advice.

Be sure that you get a chain that offers the same or better protection that the original equipment.
