Troubleshooting - Metabo W 14-125 Ergo Operating Instructions Manual

en ENGLISH
- Fit the support flange (1) on the spindle. The
flange should not turn on the spindle when
properly attached.
- Position the grinding wheel on the support flange
(1) as shown in illustration C.
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.
6.3 Securing/Releasing the clamping nut
Securing the clamping nut (10):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration D on page 2.
- A) For thin grinding wheels:
The edge of the clamping nut (10) faces upwards
so that the thin grinding wheel can be attached
securely.
B) For thick grinding wheels:
The edge of the clamping nut (10) faces
downwards so that the clamping nut can be
attached securely to the spindle.
- Lock the spindle. Turn the clamping nut (10)
clockwise using the 2-hole spanner (11) to
secure.
Releasing the clamping nut:
- Lock the spindle (see chapter 6.1). Turn the
clamping nut (10) anticlockwise using the 2-hole
spanner (11) to unscrew.
7. Use
7.1 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 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 at the intended handles, take a secure
stance and concentrate on the work.
See illustration A on page 2.
Switching the angle grinder ON just for a
moment:
Switching on: Press in the lock (4) and then press
the trigger switch (5). Let go of the lock (4).
Switching off: Release the trigger switch (5).
10
Continuous operation (depends on machine
features):
Switching on: Press in the lock (4) and hold in place.
Press and hold the trigger switch (5). The
machine is now switched on. Now press in
the lock (4) a second time to lock the trigger
switch (5) in position (continuous operation).
Switching off: Press and release the trigger switch
(5).
7.2 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.
Separating:
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.
8. Cleaning
Motor cleaning: It is possible that particles deposit
inside the power tool during operation. This impairs
the cooling of the power tool. Conductive build-up
can impair the protective insulation of the power tool
and cause electrical hazards.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner. Prior to this operation,
separate the power tool from the power source and
wear protective glasses and dust mask.
Button (6) for adjusting the handle: Occasionally
vacuum clean the button (when pressed, in all 3
main handle positions). Prior to this operation,
separate the power tool from the power source and
wear protective goggles and a dust mask.

9. Troubleshooting

Switching on procedures produce brief reductions
in voltage. Unfavourable power conditions can be
detrimental to other devices. Power impedances
smaller than 0.4 ohm should not cause any
malfunction.
10. Accessories
Use only genuine Metabo accessories.
If you need any accessories, check with your
dealer.
