Securing/releasing the clamping nut
(depending on features)
Securing the clamping nut (14):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration B on page 2.
- A) For thin grinding wheels:
The edge of the clamping nut (14) faces upwards
so that the thin grinding wheel can be attached
securely.
B) For thick grinding wheels:
The edge of the clamping nut (14) faces
downwards so that the clamping nut can be
attached securely to the spindle.
- Lock the spindle. Turn the clamping nut (14)
clockwise using the 2-hole spanner (15) to
secure.
Releasing the clamping nut:
- Lock the spindle (see chapter 7.1). Turn the
clamping nut (14) anticlockwise using the 2-hole
spanner (15) to unscrew.
8. Use
8.1
Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
The machine must not be allowed to draw in
additional dust and shavings. When switching
the machine on and off, keep it away from dust
deposits. After switching off the machine, only place
it down when the motor has come to a standstill.
Avoid switching on the machine accidentally:
always switch it off when the battery pack is
removed from the machine.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand in a
safe position and concentrate.
Machines with slide switch:
Switching on: Push the slide switch (6) forward.
For continuous activation, now tilt
downwards until it engages.
Switching off: Press the rear end of the slide
switch (6) and release.

Working instructions
Grinding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Roughing: position the machine at an angle of 30° -
40° for the best working results.
Cutting-off:
Always work against the run of the disc
(see illustration). Otherwise there is
the danger of the machine kicking
back from the cut out of control. Guide
the machine evenly at a speed
suitable for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
Sanding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Wire brushing:
Press down the machine evenly.
9. Cleaning
Remove the battery pack from the machine before
any adjustments, conversions or servicing are
performed.
Remove the battery pack periodically and wipe the
contact area of the battery pack and machine with a
dry cloth and remove deposits. If the battery pack
cannot be removed: see the Repairs chapter.
10. Troubleshooting
Electronic safety shutdown The machine has
SHUT DOWN by itself. If the slew rate of the
current is too high (for example, if the machine
suddenly seizes or kickback occurs), the machine
switches off. Switch off the machine. Switch it on
again and continue to work as normal. Try to
prevent the machine from seizing. See chapter 4.2.
11. Accessories
Use only original Metabo or CAS (Cordless Alliance
System) battery packs and accessories.
See page 4.
Use only accessories which fulfil the requirements
and specifications listed in these operating instruc-
tions.
Always use the suitable accessory and the
prescribed guard for the matching guard for
the application. See page 4. (Illustrations are
examples).
Application:
1 = surface grinding
2 = cut-off grinding
3 = drilling of holes
4 = wire brushes
5 = grinding with sanding paper
Accessories:
1.1 = grinding wheel
2.1 = cut-off wheel "metal"
