8.1Adjusting the speed (depending on features)
Set the recommended speed at the setting wheel (7).
Parting grinder and roughing discs, cup wheel, diamond parting wheel: high speed
Brush: medium speed
Grinding wheel: low to medium speed

8.2Switching 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 using the handles provided, stand in a safe position and concentrate.

8.3Working instructions
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.
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.
Wire brushing:
Press down the machine evenly.
9. Cleaning
Motor cleaning: blow compressed air through the rear ventilation slots of the machine regularly, frequently and thoroughly. Here, the machine must be held firmly.
10. Troubleshooting
Machines with VTC and TC electronics:
The electronic signal display (6) lights up and 
the load speed decreases. The coil temperature is
too high! Run the machine in idling until the electronics signal indicator switches off. Machines with VTC, TC and VC electronics:
The electronic signal display (6) flashes 
and the machine does not start. The restart 
protection is active. If the mains plug is inserted with the machine switched on, or if the current supply is restored following an interruption, the machine does not start up. Switch the machine off and on again.
