3. Operation

3.1 Description

The AVH 5020/5030/6020/6030/100-20 are reversible vibrating
plates operating on the basis of the twin-shaft resp. three-shaft
vibration system principle. The Engine drives the exciter on the
baseplate via hydraulic components.
The exciter produces the vibration required for compaction owing
to the incorporated out-of-balance weights.
The machine is guided at the tow-bar grip. It is operated with the

operating controls on the tow-bar.

The AVH 5020/5030/6020/6030/100-20 are suitable for all heavy
compaction work in the fileds of civil Engineering and road con-
struction.
It can be used to compact all ground materials such as sand,
gravel, slag, crushed stone, asphalt and composite sett paving.
Take great care on downslopes. The machine
could slip down owing to loose material or if the
surface is slippery.
Danger
Do not work on hard concrete or set asphalt sur-
facing.

II Full load
The Engine speed can be adjusted steplessly with the control le-
ver. At minimum Engine speed (I), the drive to the exciter is dis-
connected at the centrifugal clutch and the Engine idles.
The centrifugal clutch engages when the control lever is moved
approximately ¼ of its adjustment travel.
The Engine speed should always be well below or
well above the engaging speed of the centrifugal
clutch, otherwise, the clutch linings will wear very

quickly or could even be destroyed.
2 Drive lever
a Forward
b Reverse
The drive lever serves to adjust the movements in the exciter and
therefore provides a stepless control
• of the travel direction forwards (a) / backwards (b)
• of the speed
3 Emergency stop connection
The emergency stop switch serves to immediately halt the ma-
chine in emergency situations.
Once the switch knob is pressed the power transmission is inter-
rupted and the machine itself stops though the Engine continues
to run.
Following the pressing of the switch during operation:
• The switch is released by withdrawing it.
• Normal operation can then be immediately resumed. (The
travel direction and speed do not need to be reselected).
Engine start is possible with the switch depressed.
