The specified vibration value was measured with a
standardised test procedure. It can be used to
compare products or to make an initial assess-
ment of the exposure. The vibration emissions may differ
from the specified value, depending on how the power
tool is used. Operating personnel must be protected with
defined safety measures based on the estimated expo-
sure under the actual conditions of use (these must take
into account all phases of the operating cycle, e.g. the
times when the power tool is switched OFF and the times
it is switched ON, but is not under load).

The electronically controlled soft starting provides for jerk-
free starting of the machine. Due to the low machine start-
ing current a 16 A fuse is adequate.

emperAture dependent overloAd protection
For protection against overheating, when a critical tem-
perature is reached the electronic safety feature switches
into the cool-down mode. The machine then continues
to run at a speed of approx: 1,100 rpm and the electronic
constant speed control is deactivated.
After a cool-down time of approx. 10 - 20 s the machine is
again ready for operation. Turn the machine off and back
on again to activate the electronic constant speed control.
With the tool at operating temperature the temperature-
dependent overload protection reacts correspondingly
earlier.
u / r
ndervoltAge estArting protection
On short-time failure of the power voltage (plug discon-
nected, instable power mains etc.) the machine will stop.
When the power voltage recovers, the machine must be
turned OFF and back ON again. Then the machine is
ready for operation.

position. Screw screws back in and tighten down.
3.3 g
Use only grinding tools whose admissible maximum
speed is equal to or higher than the no-load speed of the
machine.
