Your risk from these exposures var-

ies, depending on how often you do 

this type of work.  To reduce your 

exposure to these chemicals: work in 

a well ventilated area, and work with 

approved safety equipment, such as 

those dust masks that are specially 

designed to filter out microscopic 

particles.  (California Health & Safety 

Code § 25249.5, 

et seq.

)

a chemical known to the State of 

California to cause cancer, and birth 

defects or other reproductive harm. 

Wash hands after handling.  (Califor-

The warnings, precautions, and in-

25. 

structions discussed in this instruction 

manual cannot cover all possible con-

ditions and situations that may occur.

Kickback and Related Warnings

Kickback is a sudden reaction to a 

pinched or snagged rotating wheel, back-

ing pad, brush or any other accessory. 

Pinching or snagging causes rapid stall-

ing of the rotating accessory which in turn 

causes the uncontrolled power tool to be 

forced in the direction opposite of the ac-

cessory’s rotation at the point of the bind-

ing.

For example, if an abrasive wheel 

is snagged or pinched by the work piece, 

the edge of the wheel that is entering into 

the pinch point can dig into the surface of 

the material causing the wheel to climb 

out or kick out. The wheel may either jump 

toward or away from the operator, depend-

ing on direction of the wheel’s movement 

at the point of pinching. Abrasive wheels 

may also break under these conditions.

Kickback is the result of power tool 

misuse and/or incorrect operating proce

-

dures or conditions and can be avoided by 

taking proper precautions as given below.

Maintain a firm grip on the power 

1. 

tool and position your body and 

arm to allow you to resist kick-

back forces. Always use auxiliary 

handle, if provided, for maximum 

control over kickback or torque 

reaction during start-up.

 The opera

-

tor can control torque reactions or 

kickback forces, if proper precautions 

are taken.

never place your hand near the 

2. 

rotating accessory.

 Accessory may 

kickback over your hand.

Do not position your body in the 

3. 

area where power tool will move 

if kickback occurs.

  Kickback will 

propel the tool in direction opposite to 

the wheel’s movement at the point of 

snagging.

use special care when working 

4. 

corners, sharp edges etc. Avoid 

bouncing and snagging the ac-

cessory.

 Corners, sharp edges or 

bouncing have a tendency to snag 

the rotating accessory and cause loss 

of control or kickback.

Do not attach a saw chain wood-

5. 

carving blade or toothed saw 

blade.

 Such blades create frequent 

kickback and loss of control.
