3.3 Safety Warnings Specific for Grinding
and Abrasive Cutting-Off Operations:
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 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 and
accidental contact with wheel.
c) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
d) 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 different from
grinding wheel flanges.
e) 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.
3.4 Additional Safety Warnings Specific for
Abrasive Cutting-Off Operations:
a) Do not "jam" the cut-off wheel or apply
excessive 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.
b) 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 kickback may propel the spin-
ning wheel and the power tool directly at you.
c) 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 kick-
back may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
d) 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.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and kick-

back. 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.
f) 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 kick-
back.
3.5
a) Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations 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.
3.6
a) 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.
b) 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.
---------------------------------------------------------
Keep all enclosed documentation for future refer-
ence, and pass on your power tool only together
with this documentation.
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Grinding wheels must be stored and handled with
care in accordance with the manufacturer's
instructions.
Never use parting grinder discs for roughing work!
Do not apply pressure to the side of parting grinder
discs.
The tool must lay flat and be secured against slip-
ping, e.g. using clamps. Large workpieces must be
sufficiently supported.
If accessories with threaded inserts are used, the
end of the spindle may not touch the base of the
hole on the grinding tool. Make sure that the thread
in the accessory is long enough to accommodate
the full length of the spindle. The thread in the
accessory must match the thread on the spindle.
