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).

tArting current limitAtion
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.
t
emperAture
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.
