restart by itself and must be switched on again when the
voltage is restored.
Change or sharpen blade
Switch back on engine after cool-down time
Mount the chip suction hood or table locking mechanism
in such a way that the micro switch is started.
Reduce chip take-off
Reduce the feed speed
Reduce cutting depth and process workpiece in several

Reduce chip take-off
Reduce the feed speed
Change blades
Change or sharpen blade
Remove chips
Feed the workpiece with constant pressure and reduced
