Hand Guard
For operations with the rubber sanding plate
18 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 17.
The hand guard
17
is fastened with the auxiliary handle
6
.
Mounting the Grinding Tools
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool.
There is danger of injury when
unintentionally actuating the On/Off switch.
Do not touch grinding and cutting discs before
they have cooled down.
The discs can become very
hot while working.
Clean the grinder spindle
7
and all parts to be mounted.
For clamping and loosening the grinding tools, lock the
grinder spindle with the spindle lock button
1
.
Actuate the spindle lock button only when the
grinder spindle is at a standstill.
Otherwise, the
machine may become damaged.
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding tools. The
mounting hole diameter must fit the mounting flange without
play. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that the
direction-of-rotation arrow on the diamond cutting disc and
the direction of rotation of the machine (see direction-of-rota-
tion arrow on the machine head) agree.
To fasten the grinding/cutting disc, screw on the clamping nut
12
and tighten with the two-pin spanner; see Section “Quick-
clamping Nut ”.
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn freely.
Make sure that the grinding tool does not
graze against the protection guard or other
parts.
A plastic part (O-ring) is fitted around the
centring collar of mounting flange
10
.
If
the O-ring is missing or dam-
aged,
the mounting flange
10
must be
replaced before resuming operation.
Flap Disc
For operations with the flap disc, always
mount the hand guard 17.
Rubber Sanding Plate
For operations with the rubber sanding plate
18, always mount the hand guard 17.
See graphics page for the mounting sequence.
Screw on the round nut
20
and tighten with the two-pin span-
ner.
Cup Brush/Disc Brush
For operations with the cup brush/wheel
brush, always mount the hand guard 17.
See graphics page for the mounting sequence.
The cup brush/disc brush must be able to be screwed onto the
grinder spindle until it rests firmly against the grinder spindle
flange at the end of the grinder spindle threads. Tighten the
cup brush/disc brush with an open-end spanner.
Quick-clamping Nut
Use the quick-clamping nut only for grinding
and cutting discs up to a max. diameter of
115 mm or 125 mm.
After mounting the mounting flange and grinding/cutting disc,
the clear thread length “X of the grinding spindle” must be
at
least 4 mm
.
Lock the grinding spindle with the spindle lock button
1
. Fold
up the clip of the quick-clamping nut
13
and manually screw
the nut onto the grinding spindle in clockwise direction
7
until
firmly seated on the grinding/cutting disc. Fold the clip down
again.
To release, fold up the clip of the quick-clamping nut
13
and
manually unscrew the nut off of the locked spindle in anticlock-
wise direction. If necessary, the quick-clamping nut
13
can
also be loosened with the corresponding two-pin spanner
after folding up the clip.
