material causing the wheel to climb out or kick out. The 

wheel may either jump toward or away from the operator, 

depending 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 procedures or conditions and can be 

avoided by taking proper precautions as given below.

a)  Maintain a firm grip on the power tool and 

position your body and arm to allow you to 

resist kickback forces. Always use auxiliary 

handle, if provided, 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.

b)   Never place your hand near the rotating 

accessory. 

Accessory may kickback over your 

hand.

c)   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 wheel’s movement at the point of snagging.

d)   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 

accessory and cause loss of control or kickback.

e)   Do not attach a saw chain woodcarving 

blade or toothed saw blade. 

Such blades create 

frequent kickback and loss of control.

ADDITIONAL SAFETY 

INSTRUCTIONS FOR 

GRINDING AND CUTTING-

OFF OPERATIONS 

Safety Warnings Specific for Grinding and 

Abrasive Cutting-Off Operations:

a)   Use only wheel types that are recommended 

for your power tool and the specific guard 

designed for the selected wheel. 

Wheels for 

which the power tool was not designed cannot be 

adequately guarded and are unsafe.

b)  The guard must be securely attached to 

the power tool and positioned for maximum 

safety, so the least amount of wheel is 

exposed towards the operator.

 The guard 

helps to protect the operator from broken wheel 

fragments, accidental contact with wheel and sparks 

that could ignite clothing.

c)   Wheels must be used only for recommended 

applications. 

For example: do not grind with the 

side of cut-off wheel. Abrasive cut-off wheels are 

intended for peripheral grinding, side forces applied 

to these wheels may cause them to shatter.

d)  Always use undamaged wheel flanges 

that are of correct size and shape for your 

selected wheel. Proper wheel flanges 

support the wheel thus reducing the 

possibility of wheel breakage.

 Flanges for 

cut-off wheels may be different from grinding wheel 

flanges.

e)  Do not use worn down wheels from larger 

power tools. 

Wheel intended for larger power tool 

is not suitable for the higher speed of a smaller tool 

and may burst.

ADDITIONAL SAFETY 

INSTRUCTIONS 

FOR CUTTING-OFF 

OPERATIONS

Additional Safety Warnings Specific for Abrasive 

Cutting-Off Operations:

a)  Do not “jam” the cut-off wheel or apply 

excessive pressure. Do not attempt to make 

an excessive depth of cut. 

Overstressing the 

wheel increases the loading and susceptibility to 

twisting or binding of the wheel in the cut and the 

possibility of kickback or wheel breakage.

b)  Do not position your body in line with and 

behind the rotating wheel. 

When the wheel, at 

the point of operation, is moving away from your 

body, the possible kickback may propel the spinning 

wheel and the power tool directly at you.

c)  When wheel is binding or when interrupting 

a cut for any reason, switch off the power 

tool and hold the power tool motionless 

until the wheel comes to a complete stop. 

Never attempt to remove the cut-off wheel 

from the cut while the wheel is in motion 

otherwise kickback may occur.

 Investigate and 

take corrective action to eliminate the cause of wheel 

binding.

d)  Do not restart the cutting operation in the 

workpiece. Let the wheel reach full speed 

and carefully re-enter the cut. 

The wheel 

may bind, walk up or kickback if the power tool is 

restarted in the workpiece. 

e)  Support panels or any oversized workpiece 

to minimize the risk of wheel pinching and 

kickback. Large workpieces tend to sag 

under their own weight. 

Supports must be 

placed under the workpiece near the line of cut and 

near the edge of the workpiece on both sides of the 

wheel.

f)   Use extra caution when making a “pocket 

cut” into existing walls or other blind areas. 

The protruding wheel may cut gas or water pipes, 

electrical wiring or objects that can cause kickback.
