Clean the grinder spindle
5
and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er 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 be-
come 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 di-
rection-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.
Place the toothed supporting disc
10
onto the spindle collar
in such a manner that the key grooves engage in each other.
The flat surface of the supporting disc
10
must face towards
the grinding tool.
Place the grinding tool onto the supporting disc
10
. Pay atten-
tion that the grinding tool is positioned centrally and without
play on the supporting disc
10
.
Note:
When assembling, make sure that the clamping nut that
matches to the grinding tool is used, see graphics page.
Straight grinding discs
11
: Screw on the clamping nut
13
and
tighten with the two-pin spanner.
Offset grinding disc
12
: Screw on the clamping nut
17
/
18
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 oth-
er parts.
A plastic part (O-ring) is fitted around
the centring collar of mounting flange
15
.
If the O-ring is missing or dam-
aged,
the mounting flange
15
must be
replaced before resuming operation.
Flap Disc
For operations with the flap disc, always mount the
hand guard 19.
Rubber Sanding Plate
For operations with the rubber sanding plate 21, al-
ways mount the hand guard 19.
See graphics page for the mounting sequence.
Before mounting the rubber sanding plate
21
, put the 2 spac-
er discs
20
onto the grinder spindle
5
.
Screw on the round nut
23
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 19.
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. Tight-
en 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-clamping nut
18
in-
stead of the clamping nut
17
.
The quick-clamping nut 18 may be used only for grind-
ing or cutting discs.
Use only a flawless, undamaged quick-clamping nut 18.
When screwing on, pay attention that the side of the
quick-clamping nut 18 with printing does not face the
grinding disc; the arrow must point to the index mark 28.
Lock the grinder spindle with
the spindle lock button
1
. To
tighten the quick-clamping
nut, firmly turn the grinding
disc in clockwise direction.
A properly attached, undam-
aged quick-clamping nut can
be loosened by hand when
turning the knurled ring in an-
ticlockwise direction.
Never loosen a tight quick-
clamping nut with pliers. Al-
ways use the two-pin span-
ner.
Insert the two-pin span-
ner as shown in the
illustration.
