that are of correct size and shape for
your selected wheel.
Proper wheel flang
-
es support the wheel thus reducing the
possibility of wheel breakage. Flanges for
cut-off wheels may be different from grind
-
ing wheel flanges.
►
Do not use worn down wheels from
larger power tools.
Wheel intended for
larger power tool is 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 pressure. Do not attempt to
make an excessive depth of cut.
Over-
stressing 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 rotating wheel.
When the
wheel, at the point of operation, 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 inter-
rupting 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 reenter the cut.
The
wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
►
Support panels or any oversized work-
piece to minimize the risk of wheel
pinching and kickback.
Large workpieces
tend to sag under their own weight. Sup-
ports 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 existing 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 Wire Brush-
ing operations
►
Be aware that wire bristles are thrown
by the brush even during ordinary op-
eration. 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 in-
terference 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 instructions Use
safety goggles.
►
Use suitable detectors to determine if
there are hidden 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 explosion. Breaking water
pipes causes property damage.
►
Do not touch grinding and cutting discs
until they have cooled down.
The discs
can become very hot while working.
►
Release the On/Off switch and set it to
the Off position when the power supply
is interrupted, e.g. when the battery
pack is removed.
This prevents uncon-
trolled restarting.
►
Secure the workpiece. A workpiece
clamped with clamping devices or in a vice
is held more secure than by hand.
►
Avoid accumulation of dust in the work-
place.
Dust can be easily ignited.
►
Install the protective cover in such a
way that it prevents sparks from flying
in the direction of the user.
By screwing in or out of the set
screw you can change the clamping
force of the protective cover. Make sure that
the protective cover is securely fastened and
check it regularly.
►
Only press the spindle lock button when
the spindle is at a standstill! Otherwise, the
power tool may be damaged.
►
After mounting the grinding tool, before
switching it on, check that the tool has
been mounted correctly and that it can ro-
tate freely.
►
Check that the sanding tool rotates freely
without rubbing against the guard or other
parts.
►
Pressing too hard can overload the power
tool. Overloading can cause overheating
or damage to the power tool. After heavy
use, let the power tool run at idle for a few
more minutes to allow it to cool down.
