OPERATION

KICKBACK

See Figures 8 - 11.

Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action which pinches the blade in the wood.

WARNING:

To avoid kickback, release switch immediately if blade binds or saw stalls. Kickback could cause you to lose control of the saw. Loss of control can lead to serious injury.

To guard against kickback, avoid dangerous practices such as the following.

nSetting blade depth incorrectly

nSawing into knots or nails in workpiece

nTwisting the blade while making a cut

nMaking a cut with a dull, gummed up, or improperly set blade

nSupporting the workpiece incorrectly

nForcing a cut

nCutting warped or wet lumber

nOperating the tool incorrectly or misusing the tool

To lessen the chance of kickback, follow these safety prac- tices.

nKeep the blade at the correct depth setting. The depth setting should not exceed 1/4 in. below the material being cut.

nInspect the workpiece for knots or nails before cutting. Never saw into a knot or nail.

nMake straight cuts. Always use a straight edge guide when rip cutting. This helps prevent twisting the blade.

nUse clean, sharp, and properly set blades. Never make cuts with dull blades.

nSupport the workpiece properly before beginning a cut.

nUse steady, even pressure when making a cut. Never force a cut.

nDo not cut warped or wet lumber.

nHold the saw firmly with both hands and keep your body in a balanced position so as to resist the forces if kickback should occur.

WARNING:

When using the saw, always stay alert and exercise control. Do not remove the saw from the workpiece while the blade is moving.
