Machines with the designation W...RT:
Continuous operation (depending on features)
I
Switching on: Switch the machine on as described

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.
- Slide the spring that pushes the lever in position to
the side and re-insert the lever (15) (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.
9. 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 or by blowing in dry air.
Prior to this operation, separate the power tool from
the power source and wear protective glasses and
dust mask.
10. Troubleshooting
Machines with VTC and TC electronics:
The electronic signal display lights up
and the load speed decreases (not
W...RT). (7) There is too much load on the
machine! Run the machine in idling until the
electronics signal indicator switches off.
The machine does not start. The
electronic signal display (7) (depends on
model) flashes. The restart protection is
active. If the mains plug is inserted with the machine
switched on, or if the power supply is restored
following an interruption, the machine does not start
up. Switch the machine off and on again.
