8. Use
8.1
Switching On and Off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
Avoid the machine swirling up or taking in dust
and chips. 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.
Machines with slide switch:

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.
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
Restart protection: 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.
