7.3 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.
Abrasive 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.
7.4 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=3.0Nm +/- 0.3Nm.
- 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.
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 DIALSPEED and DYNAMAX electronics:
The electronic signal display lights up and the load speed decreases. (7) There is too much
load on the machine! Run the machine in idling until the electronics signal indicator switches off.
Machines with DIALSPEED, DYNAMAX electronics:
The electronic signal display (7) flashes and the machine doesn’t start. 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.
