1 Control lever
The control lever serves for adjustment of the unbalances in the
exciter and in turn for coninuous regulation.
I Forward
0 Point compacting
II Reverse
The control lever remains automatically in position only when set
to the maximum forward travel setting (a). In any other position,
the control lever moves in the direction of maximum forward
travel when released.
If the control lever is operated too quickly several times, the shift
lever will block in reverse travel. In this case:
•
Release lever in forward travel position up to maximum for-
ward travel position
•
Blocking is cleared within a few seconds and perfect shifting is
possible
The control lever can be operated only with the engine running.
The lever blocks if operated when the machine is stationary.
Blocking is immediately cleared when the engine is restarted.

The motor speed can be adjusted steplessly with the control le-
ver. At minimum motor speed (min), the drive to the exciter is dis-
connected at the centrifugal clutch and the motor idles. The cen-
trifugal clutch engages when the control lever is moved approxi-
mately ¼ of its adjustment travel.
