the speed controller (D) either be placed in the „0“ speed
position or the unit turned off at the on/off switch.

tents. When using the foot pedal, attach the pedal to its con-
necting socket „FOOT CONTROL“ (G) on the rear side of

foot switch (H).

IN CASES OF MALFUNCTIONING
• Check that the power supply is correct.
• Check whether the hand unit is connected correctly to the
main unit.
• Check whether the unit is switched „on“ (the green control
LED (I) must be glowing).
• Check whether the fuse (J) is still intact.
The fuse is to be found on the rear side of the unit. Be-
fore changing the fuse, please be sure to unplug the unit
from the mains outlet. To change the fuse, use a screwdri-
ver to unscrew the fuse holder and replace the micro fuse
(T 2 A / 250 V).
• If the problems have still not been solved after following
these steps, please consult your service center immediately.
