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 fragments,
accidental contact with wheel and sparks that could ignite
clothing.
Wheels must be used only for recommended applications.
For example: do not grind with the side of the cut-off
wheel. Abrasive cut-off wheels are intended for periph-
eral grinding; side forces applied to these wheels may
cause them to shatter.
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 differ-
ent 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 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 sus-
ceptibility 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 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 wheel is binding or when interrupting a cut for any
reason, switch off the power tool and hold the power 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 eliminate
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 exist-
ing 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. Fol-
low manufacturers recommendations, when selecting
sanding paper. Larger sanding paper extending beyond
the sanding pad presents a laceration hazard and may
cause snagging, tearing of the disc, or kickback.
Safety warnings specific for wire brushing opera-
tions
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.
Further safety warnings
Use elastic spacers/liners when these are provided with
the grinding accessory.
Make sure that the application tools are mounted in
accordance with the manufacturers instructions. The
mounted application tools must be able to rotate freely.
Incorrectly mounted application tools can become loose
during operation and be thrown from the machine.
Handle grinding accessories carefully and store them
according to the manufacturer's instructions. Damaged
grinding accessories can develop cracks and burst during
operation.
When using application tools with a threaded insert, take
care that the thread in the application tool is long enough
to hold the spindle length of the power tool. The thread in
the application tool must match the thread on the spindle.
Incorrectly mounted application tools can loosen during
operation and cause injuries.
Do not direct the power tool against yourself, other per-
sons or animals. Danger of injury from sharp or hot
application tools.
Beware of any concealed electric cables, gas or water
conduits. Check the working area before commencing
work, e. g. with a metal detector.
Use a stationary extraction system and frequently blow
out the ventilation slots. When working metal under
extreme operating conditions, it is possible for conduc-
tive dust to settle in the interior of the power tool. The
total insulation of the power tool can be impaired.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Always work with the auxiliary handle. The auxiliary han-
dle ensures reliable guiding of the power tool.
Never look or stare into the light of the power tool's lamp
from a short distance. Never point the light of the lamp
into the eyes of other persons in close vicinity. The radi-
ation produced by the lamp can be harmful for the eye.
After working gypsum-containing materials: Blow out the
ventilation openings of the power tool and the switch ele-
ment with dry and oil-free compressed air. Otherwise,
gypsum-containing dust can settle in the power tool
housing and switch element, which can harden in connec-
tion with humidity. This can impair the switching mecha-
nism.
