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 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.
An O-ring (plastic part) is inserted
in the mounting flange 10 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 10 is mounted.
Flap Disc
For operations with the flap disc, always
mount the hand guard 14.

Lock the grinder spindle
with the spindle lock but-
ton 1. 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
with pliers. Always use
the two-pin spanner.
Insert the two-pin spanner
as shown in the illustra-
tion.
Rubber Sanding Plate
For operations with the rubber sanding plate
16, always mount the hand guard 14.
See graphics page for the mounting sequence.
WKS 230 E: 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 WKS 230 SE: 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
nut
grinder spindle flange at the end of the grinder spindle
threads. Tighten the cup brush/disc brush with an
open-end spanner.
Note for WKS 230 SE: When loosening the grind-
ing tool, an increased expenditure of force must be
taken into account.
