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.
 Always feed the bit into the material in the same direc-
tion as the cutting edge is exiting from the material
(which is the same direction as the chips are thrown).
Feeding the tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and pull the tool in
the direction of this feed.
 When using cut-off wheels, high-speed cutters or tung-
sten carbide cutters, always have the work securely
clamped. These wheels will grab if they become slightly
canted in the groove, and can kickback. When a cut-off
wheel grabs, the wheel itself usually breaks. When the
steel saw, high-speed cutters or tungsten carbide cutter
grab, it may jump from the groove and you could lose con-
trol of the tool.
Additional safety instructions for grinding
 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 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
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
and electric shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property damage or
may cause an electric shock.
 Release the On/Off switch and set it to the off position
when the power supply is interrupted, e. g., in case of a
power failure or when the mains plug is pulled. This pre-
vents uncontrolled restarting.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
