Metabo W 9-100 Notice Originale page 19

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 just
before the grinding disc stops. (4) The "Quick"
clamping nut (1)loosens itself by around half a turn
and can be removed without additional effort or
tools.
7.4 Securing/Releasing the 2-hole nut
(depending on features)
Securing the 2-hole nut (13):
The 2 sides of the 2-hole nut are different. Screw the
2-hole nut onto the spindle as follows:
See illustration B on page 2.
- X) For thin grinding discs:
The edge of the 2-hole nut (13) faces upwards so
that the thin grinding disc can be attached
securely.
Y) For thick grinding discs:
The edge of the 2-hole nut (13) faces downwards
so that the 2-hole nut can be attached securely to
the spindle.
Z) Only for W 9-100:
The collar of the 2-hole nut faces downwards and/
or the flat surface faces upwards.
- Locking the spindle. Turn the 2-hole nut
(13)clockwise using the 2-hole spanner (14) to
secure.
Releasing the 2-hole nut:
- Lock the spindle (see chapter 7.1). Turn the 2-hole
nut (13) anticlockwise using the 2-hole spanner
(14) to unscrew.
8. Use
8.1 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.
8.2 Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
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
securely and concentrate.
Avoid the machine swirling up or taking in dust
and chips. After switching off the machine,
only place it down when the motor has come to a
standstill.
Machines with slide switch:
0
Switching on: Push the sliding switch forward. (5)
For continuous activation, now tilt
downwards until it engages.
Switching off: Press the rear end of the slide
switch (5) and release it.
Machines with paddle switch
(with dead man function):
0
Switching on: Slide the switch-on lock (10) in the
direction of the arrow and press the trigger
(9).
Switching off: Release the trigger switch. (9)
8.3 Working Directions
Grinding and sanding operations:
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.
Rough grinding: position the machine at an angle of
30° - 40° for the best working results.
Cutting-off operations:
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.
Wire brushing:
Press down the machine evenly.
8.4 Rotate gear housing
See illustration D on page 3.
- Disconnect from the power supply.
- Unscrew the fastening screw (a) of the lever (15).
Remove the screw, lever (with its sheet metal part)
and put aside.
- Unscrew the 4 gear housing screws (b).
CAUTION! Do not remove the gear housing!
- Turn the gear housing to the desired position
without removing it.
- Screw in the 4 gear housing screws (b) in the
available threads! Tightening torque = 3.0 Nm +/-
0.3 Nm.
