cooling effect in no load mode. Repeated
automatic cut off indicates, tool is being
overloaded.

Caution:
Electrical surges and high
frequency interference may cause RPM
fluctuations up to 30% which will disappear as
soon as power source conditions stabilize.
Due to electromagnetic interference at a lower
speed range the drive motor may shut-off
prematurly. In this case, activate on/off switch
and restart.
Attention
: Even if the cut-out is not activated,
danger of overloading always exists, thus
don’t force the tool in order not to increase
unnecessarily excessive current draw, which
overheads the motor.
