.1 
The vibration required for compaction is produced by the exciter (5) which is firmly joined 
to the lower mass (8). This exciter (5) is designed as a central vibrator with aligned 
vibrations. Such a principle permits the direction of vibration to be changed by turning the 
eccentric weights. In this way an infinitely variable transition between vibration in forward 
motion, at standstill and in reverse motion is possible. This process is hydraulically 
controlled with the operating control handle (1) on the handle bar (2).

The drive engine (11) anchored to the upper mass (7) drives the exciter (5). The torque is 
transmitted by means of a friction connection through the centrifugal clutch (4) and the exciter V-
belt (6).
