Functional description
The vibration required for compaction is generated by the exciter (9) that is permanently attached to the
base plate (10). The exciter (8) is designed as a central vibrator with directional vibrations.
This principle allows you to change the direction of vibration by simply turning the eccentric weights (9).
This makes a gradual transition possible between the vibration states: moving forward, moving in
reverse and in a stationary position.
This procedure is hydraulically controlled with the control handle (3) on the guide handle head (4).
The drive motor (13) attached to the upper mass (5) powers the exciter (9). The torque is transferred
non-positively by the centrifugal clutch (7) and the exciter V-belt (8).
When the motor speed is low, the centrifugal clutch (7) interrupts the power flow to the exciter (9) which
allows the drive motor (13) to idle properly. The speed of the drive motor (13) can be varied at the throttle
lever (2).
The upper mass (5) and the base plate (10) are connected to each other via 4 vibration-damping
vibration dampers (6). This damping prevents very high frequencies from being transferred to the upper
mass (5). This maintains proper functioning of the drive motor (13) despite a high compaction capacity.
Depending on machine type, the drive motor may also include an electronic starter in addition to the
recoil starter.
The combustion air is aspirated via an air cleaner.
