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 ma-
chine (see direction-of-rotation arrow on the ma-
chine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the
clamping nut 12 and tighten with the two-pin span-
ner; 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 damaged, the
mounting flange 10 must be re-
placed before resuming opera-
tion.
Flap Disc

For operations with the flap disc, always
mount the hand guard 14.
Rubber Sanding Plate
 For operations with the rubber sanding plate
16, always mount the hand guard 14.
See graphics page for the mounting sequence.
BAG 230-1 CLB: Before mounting the rubber
sanding plate 16 , put the 2 spacer discs 15 onto
the grinder spindle 4 .
Screw on the round nut 18 and tighten with the
two-pin spanner.
Note for BAG 230-1 CLBB: When loosening the
round nut 18 , an increased expenditure of force
must be taken into account.
Cup Brush/Disc Brush

For operations with the cup brush/wheel
brush, always mount the hand guard 14.
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.
Note for BAG 230-1 CLBB: When loosening the
grinding tool, an increased expenditure of force
must be taken into account.
Approved Grinding Tools
All grinding tools mentioned in these operating in-
structions can be used.
The permissible speed [min
-1
] or the circumferen-
tial speed [m/s] of the grinding tools used must at
least match the values given in the table.
Therefore, observe the permissible
rotational/cir-
cumferential speed on the label of the grinding
tool.
Rotating the Main Handle
 Before any work on the machine itself, pull the
mains plug.
The main handle 23 can be rotated with respect to
the machine housing toward the left or right in
steps of 90°. In this manner, the On/Off switch can
be brought into a more convenient position for spe-
cial working situations, e.g., for cutting operations
using the cutting guide with dust extraction protec-
tion guard 20 or for left-handed persons.
Press the handle unlocking button 24 in the direc-
tion of the arrow and at the same time turn the main
handle 23 to the requested position until it latches.
