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.

8.2 Working instructions
Grinding and sanding operations:
Press down the machine evenly on the surface and
move back and forth so that the surface of the work-
piece 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 suit-

10. Troubleshooting

Switching on the machine reduces the voltage
briefly. Unfavourable mains power conditions may
have a detrimental effect on other machines.
Network impedances less than 0.4 ohms should not

restored following an interruption, the machine
does not start up. Switch the machine off and on
again.
