3. Operation
3.1 Description
The APR 4920 / 5920 is a reversible vibrating plate operating on
the basis of the twin-shaft vibration system principle. The engine
drives the exciter on the baseplate via a centrifugal clutch and a
V-belt.
The exciter produces the vibration required for compaction as a
result of the built-in imbalance.
The machine is guided at the tow-bar grip. It is operated with the
operating controls on the tow-bar.
APR 4920 / 5920 is suitable for all compaction work in the fields
of civil engineering an droad construction.
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 use the machine on hard concrete, set as-
phaltic surfaces, highly frozen or unstable sur-
faces.
