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 pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.



Maintain a firm grip on the power tool and position your 
body and arm to allow you to resist kickback forces. Al-
ways 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.



Never place your hand near the rotating accessory. 

Ac-

cessory 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 wheel’s movement at the 
point of snagging.



Use special care when working corners, sharp edges, 
etc. Avoid bouncing and snagging the accessory. 

Cor-

ners, 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 woodcarving blade or 
toothed saw blade. 

Such blades create frequent kickback 

and loss of control.

Safety warnings specific for Grinding and Abrasive Cut-
ting-Off operations



Use only wheel types that are recommended for your 
power tool and the specific guard designed for the se-
lected wheel. 

Wheels for which the power tool was not de-

signed cannot be adequately guarded and are unsafe.



The grinding surface of the 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.



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 operator from broken wheel frag-
ments, accidental contact with wheel and sparks that 
could ignite clothing.



Wheels must be used only for recommended applica-
tions. For example: do not grind with the side of the 
cut-off wheel. 

Abrasive cut-off wheels are intended for 

peripheral grinding; side forces applied to these wheels 
may cause them to shatter.



Always use undamaged wheel flanges that are of cor-
rect size and shape for your selected wheel. 

Proper 

wheel flanges support the wheel thus reducing the possi-
bility of wheel breakage. Flanges for cut-off wheels may be 
different from grinding wheel flanges.



Do not use worn down reinforced wheels from larger 
power tools. 

Wheels intended for larger power tools are 

not suitable for the higher speed of a smaller tool and may 
burst.

Additional safety warnings specific for abrasive cutting 
off operations



Do not “jam” the cut-off wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth of cut. 

Overstressing the wheel increases the loading and suscep-
tibility to twisting or binding of the wheel in the cut and the 
possibility of kickback or wheel breakage.



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. 



When wheel is binding or when interrupting a cut for 
any reason, switch off the power tool and hold the pow-
er 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 elimi-

nate the cause of wheel binding.



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.



Support panels or any oversized workpiece to minimize 
the risk of wheel pinching and kickback. 

Large work-

pieces 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.



Use extra caution when making a “pocket cut” into ex-
isting walls or other blind areas. 

The protruding wheel 

may cut gas or water pipes, electrical wiring or objects that 
can cause kickback.

Safety warnings specific for sanding operations



Do not use excessively oversized sanding disc paper. 
Follow manufacturers recommendations, when select-
ing sanding paper. 

Larger sanding paper extending be-

yond the sanding pad presents a laceration hazard and 
may cause snagging, tearing of the disc, or kickback.

Safety warnings specific for wire brushing operations



Be aware that wire bristles are thrown by the brush 
even during ordinary operation. Do not overstress the 
wires by applying excessive load to the brush. 

The wire 

bristles can easily penetrate light clothing and/or skin.



If the use of a guard is recommended for wire brushing, 
do not allow any interference of the wire wheel or 
brush with the guard. 

Wire wheel or brush may expand in 

diameter due to work load and centrifugal forces.

Additional safety warnings

Wear safety goggles.



Use suitable detectors to determine if utility lines are 
hidden in the work area or call the local utility company 
for assistance. 

Contact with electric lines can lead to fire
