Operation
Starting Operation
f
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
When operating the machine with power from
mobile generators that do not have sufficient re-
serve capacity or are not equipped with suitable
voltage control with starting current amplifica-
tion, loss of performance or untypical behavior
can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to
the mains voltage and frequency.

Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a test
run for at least one minute with no load. Do
not use damaged, out-of-centre or vibrating
grinding tools.
Damaged grinding tools can
burst and cause injuries.
Kickback stop
In case of a sudden drop in speed,
e.g., caused by a jammed disc
while cutting, the power supply to
the motor is electronically inter-
rupted.
To
restart the operation
, switch the On/Off
switch
4
to the Off position and start the ma-
chine again.
Restarting Protection
The restarting protection feature prevents un-
controlled restarting of the machine after an in-
terruption in the power supply.
To
restart the operation
, switch the On/Off
switch
4
to the Off position and start the ma-
chine again.
Reduced starting current
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Note:
When the machine runs with full speed af-
ter switching on, the reduced starting current,
the restarting protection and the kickback stop
features have failed. The power tool must
promptly be sent to an after-sales service agent
for maintenance; addresses, see Section „After-
sales Service and Customer Assistance“.
Constant Electronic Control
Constant electronic control holds the speed
constant at no-load and under load, and ensures
uniform working performance.
