2.3 Description of function
2.3.1
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).

2.3.2
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).
