with this power tool can not be sufficiently
shielded and are unsafe.
► The protective and extraction hood must be
mounted on the power tool securely. The pro-
tective and extraction hood is designed to pro-
tect the machine operator from flying debris
and accidental contact with the grinding disk.
► Diamond cup disks must only be used for
their recommended applications. For exam-
ple: 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
correct size and shape for the diamond cup
disk of your choice. Appropriate flanges will
support the diamond cup disk and will there-
fore lower the risk of breaking.
► Never use worn diamond cup disks of larger
power tools. Diamond cup disks for larger
power tools are not designed for the higher ro-
tational 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 accelerated uncontrol-
lably in the opposite direction of the rotat-
ing tool insert at the location of the blockage.
If e.g. a grinding disk is hooked or blocked inside
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
handling of the power tool. Appropriate pre-
ventive 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
compensate 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 recoil, and best possible reac-
tion during the run-up of the tool. The operator
will be able to compensate for the recoil force
provided appropriate preventive 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 corners, sharp edges, or when it bounces off
a surface. 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.
