are covered by at least
3.4 mm by the safety guard.
7.2 Placing the grinding wheel in position
See illustration A on page 2.
- Place the supporting flange (2) on the spindle. The
flange should not turn on the spindle when
properly attached.
- Place the grinding wheel on the support flange (2).
The grinding wheel must lay flat on the supporting
flange. The metal flange on the parting grinder
disc must lay flat on the support flange.
7.3 Securing/Releasing the "Quick"
clamping nut (depending on features)
Securing the "Quick" clamping nut (1):
Do not use the "Quick" clamping nut if the
accessory has a clamping shank thicker than 8
mm! In this case, use the clamping nut (9) with 2-hole
spanner (10).
- Lock the spindle (see chapter 7.1).
- Position the "Quick" clamping nut (1) on the
spindle (3) so that the 2 lugs engage in the
2 grooves on the spindle. See illustration on
page 2.
- Tighten the "Quick" clamping nut by turning
clockwise by hand.
- Turn the grinding wheel firmly clockwise to tighten
the "Quick" clamping nut.
Releasing the "Quick" clamping nut (1):
The "Quick" clamping nut (1) must be attached
before the spindle locking button (4) can hold
the spindle!
- The machine continues to run after switching off.

the grinding wheel stops. The "Quick" clamping
nut (1) is released.
7.4 Securing/Releasing the clamping nut
(depending on features)
Securing the clamping nut (9):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration B on page 2.
- X) For thin grinding wheels:
The edge of the clamping nut (9) faces upwards
so that the thin grinding wheel can be attached
securely.
Y) For thick grinding wheels:
The edge of the clamping nut (9) faces
downwards so that the clamping nut can be
attached securely to the spindle.
- Lock the spindle. Turn the clamping nut (9)
clockwise using the 2-hole spanner (10) to secure.
