Hand Guard
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 15.
The hand guard 15 is fastened with the auxiliary han-
dle 5.
Mounting the Grinding Tools
Before any work on the machine itself, pull
the mains plug.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Clean the grinder spindle 6 and all parts to be
mounted.
For clamping and loosening the grinding tools, lock
the grinder spindle with the spindle lock button 2.
Actuate the spindle lock button only when
the grinder spindle is at a standstill. Other-
wise, 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-rotation arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the
clamping nut 10 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 cor-
rectly mounted and that it can turn freely. Make
sure that the grinding tool does not graze
against the protection guard or other parts.
An O-ring (plastic part) is inserted
in the mounting flange 8 around the
centring collar. If the O-ring is
missing or is damaged, it must
in all cases be replaced (article
number 1 600 210 039) before
the mounting flange 8 is mounted.
Flap Disc
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 15.
Place the special mounting flange (article number
2 605 703 028) and the flap disc on the grinder spin-
dle 6. Screw on the clamping nut 10 and tighten with
the two-pin spanner.

Cup Brush/Disc Brush
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap

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

For convenient changing of grinding tools without the
use of additional tools, you can use the quick-clamp-
ing nut 11 instead of the clamping nut 10.
The quick-clamping nut 11 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 11.
When screwing on, pay attention that the side
of the quick-clamping nut 11 with printing does
not face the grinding disc; the arrow must point
to the index mark 22.

Lock the grinder spindle
with the spindle lock but-
ton 2. To tighten the quick-
clamping nut, firmly turn
the grinding disc in clock-
wise direction.
A properly attached,
undamaged quick-clamp-
ing nut can be loosened
by hand when turning the
knurled ring in anticlock-
wise direction.
Never loosen a tight
quick-clamping nut with
pliers. Always use the
two-pin spanner. Insert
the two-pin spanner as
shown in the illustration.
