tal contact with the grinding disk.
► Diamond cup disks must only be used for their
recommended applications. For example: Never
grind edges with a diamond cup disk. Diamond
cup disks are designed to grind off material with
the underside of the diamond segments. Lateral
stresses on these grinding disks may cause them
to break.
► Only use undamaged clamping flanges in the cor-
rect size and shape for the diamond cup disk of
your choice. Appropriate flanges will support the
diamond cup disk and will therefore lower the risk
of breaking.
► Never use worn diamond cup disks of larger pow-
er tools. Diamond cup disks for larger power tools
are not designed for the higher rotational speeds
of smaller power tools and can break.
Recoil and associated safety notes
► Recoil is the sudden reaction of a hooked or
blocked rotating tool insert, e.g. grinding disk, cup
wheel, wire brush, etc. A hooking or blocking of the
insert will cause a sudden stop of the rotating tool
insert. As a result, the power tool will be accelerat-
ed uncontrollably in the opposite direction of the
rotating tool insert at the location of the blockage.
If e.g. a grinding disk is hooked or blocked in-
side the workpiece, the edge of the grinding disk
submerged in the workpiece may get caught
and thus break the grinding disk or cause a re-
coil. The grinding disk will then move towards
the operator or away, depending on the rota-
tional direction of the disk at the blockage loca-
tion. This may cause the grinding disk to break.
A recoil is the result of incorrect or erroneous han-
dling of the power tool. Appropriate preventive
measures - as described below - will help prevent
a recoil.
► Hold the power tool firmly and position your
body and arms in such a way as to be able to com-
pensate any recoil. Always use the second handle
(where available) to ensure a firm grip on the tool
and greatest possible control in the event of a re-
coil, and best possible reaction during the run-up
of the tool. The operator will be able to compen-
sate for the recoil force provided appropriate pre-
ventive measures are taken.
► Never position your hand in close proximity of
rotating tool inserts. A recoil could cause the tool
insert to move across your hand.
► Position your body away from the area into which
the power tool would move in case of a recoil.
A recoil will drive the power tool in the opposite
direction of the movement of the grinding disk at
the blockage location.
► Work with particular caution in the area of cor-
ners, sharp edges, etc. Prevent the tool inserts
bouncing off the workpiece or getting stuck. The
rotating tool insert is prone to getting stuck at cor-
ners, sharp edges, or when it bounces off a sur-
face. This could cause a loss of control or a recoil.
► Do not use chain disks or toothed disks. These
tool inserts often create a recoil action or loss of
control over the power tool.

Additional safety instructions

► Wear protective goggles and hearing
protection.
Do not touch the diamond cup disk un-
►
til it has cooled down. Diamond cup disks become
very hot during operation.
► Use a dust extractor when grinding stone. The
dust extractor must be certified for stone dust
extraction. The use of these devices reduces the
hazards of dust.
► Do not grind any materials or workpieces con-
taining asbestos.
► Grip the power tool firmly with both hands while
working and ensure a safe and firm stance. The
power tool must be held firmly in both hands.
► Secure the workpiece. A workpiece held in a
clamping device or bench vise is better secured
than when held by hand.
► Avoid any blockage of the diamond cup disk or
excessive contact pressure during grinding. Exces-
sive stresses on the grinding disk increases its load
and its vulnerability, i.e. it can easier get stuck or
blocked and the risk of recoil or breakage of the
grinding disk is increased.
► Switch off the power tool if the diamond cup disk
gets blocked or you need to interrupt your work
for any reason. Hold the power tool steady until
the disk has come to a complete standstill.
► Do not switch the power tool back on while it is
in contact with the workpiece. Allow the grinding
disk to reach its full speed before recommencing
work.
► Only use the power tool with the protective hood
opened along wall edges. The protective hood
must always be closed when working on flat areas.
► Check the device, cable and plug before each use.
Any damage detected must only be repaired by
a certified electrician. Connect the wall plug only
with the machine switched off.
► When working outdoors, operate the machine
with a residual current operated circuit-breaker
(RCD) with max. 30 mA. If the grinder is shut down
via the RCD, it must be checked and cleaned.
► Pull the mains plug and check that the main
switch is in OFF position if you leave the machine
unattended, e.g. during installation or removal
