and an excessive accumulation of powdered metal 

may cause electrical hazards. 

o) Do not operate the power tool near

flammable materials. Sparks could ignite these 

materials. 

p) Do not use accessories that require liquid

coolants. Using water or other liquid coolants may 

result in electrocution or shock. 
3.2 Kickback and related warnings

Kickback is a sudden reaction to a pinched or 

snagged sanding wheel, backing pad, brush or any 

other accessory. Pinching or snagging causes the 

rotating accessory to stall rapidly, This in turn 

causes the uncontrolled power tool to be forced in 

the opposite direction from which the accessory is 

rotating at the pinched or snagged point. 

For example, if an abrasive wheel is snagged or 

pinched by the workpiece, the edge of the wheel 

entering the pinch point can dig into the surface of 

the material causing the wheel to climb out or kick 

out. The abrasive wheel may either jump toward or 

away from the operator, depending on direction the 

disc is moving at the pinch point. 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 if suitable precautionary measures 

are taken as described below. 

a) Maintain a firm grip on the power tool and

position your body and arm so that you can 

resist kickback forces. Always use the 

additional handle, if provided, for maximum 

control over kickback or a 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 a rotating

accessory. The accessory may kickback over your 

hand.

c) Do not position your body in the area

where the power tool will move if kickback

occurs. Kickback

will propel the tool in the direction opposite to the 

grinding wheel’s movement at the pinch or snag

point. 

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 can cause you to lose 

control. 
3.3 Safety Warnings Specific for Grinding 

and Cut-Off Grinding:

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 the centre depressed

wheels must be mounted below the plane of

the guard lip. An improperly mounted grinding

wheel that projects through the plane of the guard 

lip cannot be adequately guarded.

c) The guard must be securely attached to the

power tool and positioned for maximum safety

so that the least amount of wheel is exposed 

towards the operator. The guard helps to protect 

operator from broken wheel fragments and 

accidental contact with the wheel and sparks which 

could ignite clothing.

d) Grinding media must be used only for

recommended applications. 

For example: do not grind with the side of the 

cutting disc. Cutting discs are intended for 

grinding using the edge of the disc. Applying force 

to the sides of these discs may cause them to

shatter.

e) Always use undamaged wheel flanges that

are the correct size and shape for your selected 

grinding wheel. Proper wheel flanges support the 

grinding wheel, reducing the possibility of

breakage. Flanges for cutting discs may be different 

from grinding wheel flanges.

f) Do not use worn down grinding wheels from

larger power tools. Grinding wheels intended for 

larger power tools are not suitable for the higher 

speed of a smaller tool and may break.
3.4 Additional Safety Warnings Specific for 

Cut-Off Grinding: 

a) Do not “jam” the cutting disc or apply

excessive pressure. Do not attempt to make an

excessively deep cut. Overstressing the cutting

disc increases the load and makes the disc more 

susceptible to twisting or bending in the cut and 

more likely to kick back and break.

b) Do not position your body in line with or

behind the rotating cutting disc. When the 

cutting disc is moving away from your body at the 

point of operation, any kickback can propel the 

spinning disc and the power tool directly towards 

you.

c) If the cutting disc is stuck or when 

interrupting a cut for any reason, switch off the

power tool and hold the power tool motionless 

until the disc comes to a complete stop. Never 

attempt to remove the cutting disc from the cut 

while the disc is in motion; otherwise kickback

may occur. Investigate and take corrective action

to eliminate the cause if a disc becomes stuck.

d) Do not restart the cutting operation in the

workpiece. Let the cutting disc 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 cutting disc pinching

and kickback. Large workpieces tend to sag under 

their own weight. Supports must be placed under 

the workpiece near the line of the cut and near the 

edge of the workpiece on both sides of the wheel.
