Decommissioning - Wacker Neuson IEC Operator's Manual

10 Use and operation
Compacting fresh concrete
1. Quickly immerse the vibrator head in the fresh concrete, hold it for several seconds and slowly pull it
out again.
2. Immerse the vibrator head in all areas of the formwork and compact the fresh concrete.
Notes:
Compact especially intensively in the area of formwork corners. In these areas, the reinforcement

rate is the highest.
Avoid contact of the vibrator head with the concrete reinforcement. The following damages are

possible if the vibrator head comes into contact with the concrete reinforcement:
The connection of the concrete to the reinforcement can be lost.

The machine can be damaged.

The result of the compacting depends on the following points:

Holding time of the vibrator head in the concrete.

Diameter of the vibrator head.

Consistency of the concrete.

Reinforcement rate.

If you use a vibrator head with a smaller diameter, the compacting time to achieve the same results as
with a vibrator head with a larger diameter will increase.
Indications that the concrete is sufficiently compacted:

The concrete no longer sets.

Air bubbles no longer or rarely rise.

The sound of the vibrator head is not changing anymore.
