Operation conditions and instructions
This tool is equipped with an electronic variable speed
tachometer selector and an overload cut-out switch, which
operates as follows:
1. Soft start
2. With increased work pressure more current is drawn ,
which virtually holds speed at a constant rpm.
3. If the motor is overloaded, the electronic cuts off the
power. In this event switch at once to OFF position,
4
restart right away to assure cooling effect in no load
mode. Repeated automatic cut off indicates, tool is
being overloaded.
Attention: Even if the cut-out is not activated, danger of
overloading always exists, thus don't force the tool in or-
der not to increase unnecessarily excessive current draw,
which overheads the motor.
Speed selection
Select required speed with variable speed selector 9 for
correct surface feet./M.O.S.
