on/off switch [2-3].
WARNING
Risk of injury
Rebound, ejected parts
Before setting down the machine, wait until
the rotating tool has come to a complete stop.
9.2 Control electronics
Increases productivity, life service of the grinder,
comfort at work, as well as quality and safety of
work. Provides the following functions:
Protection against re-start
If power failure occurs during work (if the mobile
power supply plug is pulled out, if circuit breaker
fails, etc.), and the switch stays locked in the ON
position, the machine does not turn on automati-
cally once the power supply recovers. To restart
the grinder, its switch needs to be turned off fi rst
and then turned on again.
Slow start
After the grinder is turned on, control electronics
secures gradual start to operating rpm, without
pointless strokes. This reduces wear of gearing,
thus increasing the life service of the grinder.
Starting current limiting
The electronically controlled smooth start takes
care that the machine starts without jerk. As a
result of the machine's reduced starting current,
a 10 A fuse is suffi cient.
Protection in case of disk locking
When cutting disk is used for cutting, it may get
locked in the cut. To reduce the risk of injury or
burning of the machine, the electronics reacts to
rapid growth of load by turning the engine off. For
restart turn the machine off and then on again.
9.3
Aperture cover
If you wish to see the cutting area, take off the
aperture cover [2-1]. Only handle this cover when
the disc is not running.
Be careful about spattering dust particles.
