(Disassemble in reverse order.)

6. Attaching the grinding disc

Prior to any conversion work: Pull the mains
plug from the socket. The machine must be
switched off and the spindle at a standstill.
For reasons of safety, attach the cutting guard
before performing cutting-off operations (see
chapter 10. Accessories).
6.1 Locking the spindle
- Press in the spindle locking button (4) and turn the
spindle (2) by hand until the spindle locking button
engages.
6.2 Placing the grinding wheel in position
WA..., WBA..., WE...A...:
See illustration A on page 2.
The Autobalancer support flange (3) is
permanently fitted on the spindle. As is the
case with most other angle grinders, a detachable
support flange is not necessary.
The contact surfaces of the Autobalancer
support flange (3), grinding wheel and the
"Quick" clamping nut (1) must be clean. Clean if
necessary.
- Place the grinding wheel on the Autobalancer
support flange (3).
The grinding wheel must lie flat on the
Autobalancer supporting flange.
WPB..., WEPB 17-..., WEPB 19-...:
See Figure B on Page 2.
- Fit the support flange (14) on the spindle. The
flange should not turn on the spindle when
properly attached.
- Place the grinding disc on the support flange (14).
The grinding disc must lay flat on the supporting
flange. The metal flange on the parting grinder
disc must lay flat on the support flange.
6.3 Securing/Releasing the "Quick"
clamping nut (depending on features)
Securing the "Quick" clamping nut (1):
Only attach the "Quick" clamping nut (1) to
tools with "Metabo Quick System". These
tools can be identified by the red spindle lock button
(4) with "M-Quick" logo
12
Use only accessories that
are covered by at least
3.4 mm by the safety guard.
Do not use the "Quick" clamping nut if the
accessory has a clamping shank thicker than
7.1 mm! In this case, use the 2-hole nut (15) with 2-
hole spanner (16).
- Lock the spindle (see chapter 6.1).
- Position the "Quick" clamping nut (1) on the
spindle (2) 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 clamping nut (1):
Only when the "Quick" clamping nut (1) is
attached must the spindle be stopped using
the red M-Quick spindle locking button (4)!
- The machine continues to run after switching off.
- Press in the M-Quick spindle locking button (4)
just before the grinding disc stops. The "Quick"
clamping nut (1) loosens itself by around half a
turn and can be removed without additional effort
or tools.
6.4 Securing/Releasing the 2-hole nut
(depending on features)
The 2 sides of the 2-hole nut are different. Screw the
2-hole nut onto the spindle as follows:
See illustration C on page 2.
- X) For thin grinding discs:
The edge of the 2-hole nut (15) faces upwards so
that the thin grinding disc can be attached
securely.
Y) For thick grinding discs:
The edge of the 2-hole nut (15) faces downwards
so that the 2-hole nut can be attached securely to
the spindle.
- Locking the spindle. Turn the 2-hole nut (15)
clockwise using the 2-hole spanner (16) to secure.
Releasing the 2-hole nut:
- Lock the spindle (see chapter 6.1). Turn the 2-hole
nut (15) anticlockwise using the 2-hole spanner
(16) to unscrew.
7. Use
7.1 Adjusting the speed (depending on
features)
Set the recommended speed at the thumbwheel
(8). (small number = low speed; large number =
high speed)
Cutting disc, roughing disc, cup wheel and diamond
cutting disc: high speed
Brush: medium speed
Sanding plate: low to medium speed
Note: We recommend using our angle polisher for
polishing work.
7.2 Switching on and off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
