Kickback and related warnings

• Kickback is the sudden binding or snagging of a rotating wheel, brush or other accessory. Jamming or snagging causes rapid stalling of the rotating accessory which in turn causes the power tool to force itself in an uncontrolled manner in the opposite direction of the accessory’s rotation at the point of work.
• Kickback can occur as a result of misuse of power tools and/or improper operating procedures or unsuitable conditions and can be avoided by taking the precautions outlined below:
• Maintain a firm grip on the power tool, keep your body and arm so that you can resist kickback (abrupt kickback) forces.
• Always use the auxiliary handle; if provided, for maximum control over kickback or motor torque reaction during start-up.
• The operator can control torque and kickback forces. If proper precautions are taken;
• Never put your hand near the rotating attachment.
• The accessories can kick back on your hand.
• Do not put your body in the area where the power tool may move if kickback occurs.
• This drives the power tool in the opposite direction of the blade movement at the point of snagging or binding;
• Take special care when working on corners, sharp edges, among others. Avoid bouncing and jamming of the accessory.
• When working around corners, sharp edges or bouncing can cause the accessory to jam and cause loss of control of the power tool or kickback of the power tool.
