Page 24 Ver 4 - September 2016

5.7. Kickback.

5.7.1. Kickback is a sudden reaction to a pinched or snagged rotating blade.

Pinching or snagging causes rapid stalling of the rotating blade which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.

5.7.1. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip on the machine and position your body and arm to allow you to resist kickback forces.

• ALWAYS use both hands on the handle bar for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.

• NEVER place your hand near the rotating blade. The blade may kickback over your hand.

• DO NOT position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the blades movement at the point of snagging.

• Use special care when working corners, sharp edges etc.

• Avoid bouncing and snagging the accessory.

• Corners, sharp edges or bouncing have a tendency to snag the rotating blade and cause loss of control or kickback.
