FURTHER SAFETY INSTRUCTIONS 

FOR ALL OPERATIONS
Causes and Operator Prevention  

of Kickback

Kickback is a sudden reaction to a pinched or 

snagged rotating wheel, backing pad, brush or 

any other accessory. Pinching or snagging causes 

rapid stalling of the rotating accessory 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.
For example, if an abrasive wheel is snagged or 

pinched by the workpiece, 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, 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 reaction 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.

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 grinding surface of centre depressed 

wheels must be mounted below the plane 

of the guard lip

. An improperly mounted wheel 

that projects through the plane of the guard lip 

cannot be adequately protected.

 c) 

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.

 d) 

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.

 e) 

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.

 f) 

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 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 operations, is moving away from 

your body, the possible kickback may propel the 

spinning wheel and the power tool directly at 

you.
