Troubleshooting; Environmental Protection - Metabo WA 12-125 Operating Instructions Manual

en ENGLISH
Rough grinding: position the machine at an angle of
30° - 40° for the best working results.
Abrasive cutting-off operations:
Always work against the run of the disc
(see Figure). Otherwise there is the
danger of an out of control machine
kicking back from the cut. 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.
7.4 Rotate gear housing
See illustration E on page 3.
- Disconnect from the power supply.
- Unscrew the fastening screw (a) of the lever (16).
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.
- Slide the spring that pushes the lever in position to
the side and re-insert the lever (16) (with its sheet
metal part), and fix with the fastening screw (a).
Tightening torque = 5,0 Nm +/- 0,5 Nm. Check the
lever for correct function: it has to be under spring
tension.
8. 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.

9. Troubleshooting

Machines with VTC, TC and VC electronics:
The electronic signal display (7) lights up
and the load speed decreases. There is too
much load on the machine! Run the machine
in idle until the electronics signal indicator switches
off.
Machines with VTC, TC and VC electronics:
The electronic signal display (7) flashes
and the machine does not start. The restart
protection is active. If the plug is put into the
socket with the machine switched on, or if the power
supply is restored following an interruption, the
machine will not start up. Switch the machine off
and back on again.
