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.
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 kickback.
g) Do not attempt to do curved cutting.
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, which can lead to serious injury.
3.5 Safety warnings specific for sanding
operations:
a) Use proper sized sanding disc paper. Follow
the manufacturer's recommendations, when
selecting sanding paper. Larger sanding paper
extending too far beyond the sanding pad presents
a laceration hazard and may cause snagging,
tearing of the disc or kickback.
3.6 Safety warnings specific for wire
brushing operations:
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 specified 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.
3.7 Additional Safety Instructions:
WARNING – Always wear protective
goggles.
Wear ear protectors.
WARNING – Always operate the power tool
with two hands.
Do not use the guard for cutting-off
operations. When working with cut-off
wheels, always use the parting safety guard
for safety reasons.
Do not use any segmented diamond cut-off wheels
with segment slits >10 mm. Only negative segment
cutting angles are permitted.
Use bonded cut-off wheels only if these are
reinforced.
Use elastic cushioning layers if they have been
supplied with the sanding media and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect wheels from grease or
impact!
Accessories must be stored and handled with care
in accordance with the manufacturer's instructions.

Never use cut-off wheels for roughing work or
deburring! Do not apply pressure to the side of the
cut-off wheels.
The workpiece must lay flat and be secured against
slipping, 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 sanding 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.
See page 2 and chapter 14. Technical
Specifications for more information on the spindle
length and thread.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first remove the battery
pack (use non-metallic objects) and avoid
damaging internal components.
Damaged, eccentric or vibrating tools must not be
used.
Avoid damage to gas or water pipes, electrical
cables and load-bearing walls (static).
Remove the battery pack from the machine before
making any adjustments, changing tools,
maintaining or cleaning.
Make sure that the tool is switched off before fitting
the battery pack.
A damaged or cracked additional handle must be
replaced. Never operate the machine with a
defective side handle.
A damaged or cracked safety guard must be
replaced. Never operate a machine with a defective
safety guard.
Secure small workpieces. For example, clamp in a
vice.
When using dual-purpose (combined grinding and
cut-off wheels), only the following guard types must
be used: type A, type C.
See chapter 11.
Using the correct guard:
Using an incorrect guard can lead to loss of control
and serious injuries. Examples for incorrect use:
- when using a type A guard for lateral grinding, the
guard may interfere with the workpiece causing
poor control.
- when using a type B guard for cutting-off
operations with bonded cut-off wheels, there is an
increased risk of exposure to emitted sparks and
particles, as well as exposure to wheel fragments
in the event of a wheel burst.
- when using a type A, B, C guard for cutting-off
operations or lateral grinding in concrete or
masonry, there is an increased risk of exposure to
dust and loss of control resulting in kickback.
- when using a type A, B, C guard with a wheel-type
wire brush with a thickness greater than the
maximum permitted thickness, the wires may
catch on the guard leading to breaking of the
wires.
Always use the matching guard for the accessory.
