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.
Wheels must be used only for specified applications.
u
For example: do not grind with the side of cut-off
wheel. Abrasive cut-off wheels are intended for peri-
pheral grinding, side forces applied to these wheels may
cause them to shatter.
Always use undamaged wheel flanges that are of cor-
u
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the pos-
sibility 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.
u
A wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
When using dual purpose wheels always use the cor-
u
rect guard for the application being performed. Failure
to use the correct guard may not provide the desired level
of guarding, which could lead to serious injury.
Additional safety warnings specific for cutting-off
operations:
Do not "jam" the cut-off wheel or apply excessive
u
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.
Do not position your body in line with and behind the
u
rotating wheel. When the wheel, at the point of opera-
tion, is moving away from your body, the possible kick-
back may propel the spinning wheel and the power tool
directly at you.
When the wheel is binding or when interrupting a cut
u
for any reason, switch off the power tool and hold it
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 elim-
inate the cause of wheel binding.
Do not restart the cutting operation in the workpiece.
u
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 minim-
u
ize 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.
Use extra caution when making a "pocket cut" into ex-
u
isting walls or other blind areas. The protruding wheel
may cut gas or water pipes, electrical wiring or objects
that can cause kickback.
Do not attempt to do curved cutting. Overstressing the
u
wheel increases the loading and susceptibility to twisting

or binding of the wheel in the cut and the possibility of
kickback or wheel breakage, which can lead to serious in-
jury.
Safety warnings specific for sanding operations:
Use proper sized sanding disc paper. Follow manufac-
u
turers recommendations, when selecting sanding pa-
per. Larger sanding paper extending too far beyond 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
u
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 specified for wire brushing, do
u
not allow any interference of the wire wheel or brush
with the guard. Wire wheel or brush may expand in dia-
meter due to work load and centrifugal forces.
Additional safety information
Wear safety goggles.
The protective guard must not be used for
cutting. With a suitable adapter, the protective
guard can also be used for cutting.
Hold the power tool firmly with both hands
and make sure you have a stable footing. The
power tool can be more securely guided with
both hands.
For application tools with an internal thread, such as
u
brushes, attention must be paid to the max. thread
length of the grinding spindle. The spindle end must not
touch the base of the application tool.
Use suitable detectors to determine if there are hid-
u
den supply lines or contact the local utility company
for assistance. Contact with electric cables can cause
fire and electric shock. Damaging gas lines can lead to ex-
plosion. Breaking water pipes causes property damage.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Release the On/Off switch and set it to the Off posi-
u
tion when the power supply is interrupted, e.g. when
the battery pack is removed. This prevents uncontrolled
restarting.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
Store the application tools inside buildings, in a dry,
u
frost-free room at a uniform temperature.
Remove the application tools before transporting the
u
power tool. This will allow you to avoid damage.
