6.2 Notes on compacting fresh concrete
Submerging the vibratory poker into the fresh concrete causes de-aeration and compaction of the fresh concrete within the area of influence of the vibratory poker. The result of compaction generally depends on the following factors:

• Consistency of the concrete.
• Density of reinforcement.
• Diameter of the vibratory poker.
• Dwell time of the vibratory poker in the concrete.

With a small-diameter vibratory poker, for example, you have to compact for longer to achieve the same effect as you would with a large-diameter vibratory poker.

The concrete is sufficiently compacted when:

• No more bubbles rise to the surface.
• The concrete no longer subsides.
• The sound made by the vibratory poker no longer changes.

Submerge the vibratory poker into the concrete in all areas of the formwork. Compact the concrete with particular intensity at the formwork corners, because these are the areas with the highest density of reinforcement.
Avoid bringing the vibratory poker into contact with the reinforcement. The adherence of the concrete to the reinforcement can be lost and the vibratory poker can be damaged.

6.3 Performing compacting work
For optimum results, always keep the submerged vibratory poker vertical and avoid sideways movements.
Do not switch the product on until the vibratory poker is fully submerged in the fresh concrete.

1. Hold the product securely with one hand on the housing (see → page 19), while inserting the vibratory poker into the fresh concrete.
2. Set the switch-on interlock to and press the control switch. → page 21
3. Allow the vibratory poker to remain in the fresh concrete for several seconds.
4. Switch the product off and set the switch-on interlock to .
5. Lift the product straight up to withdraw the vibratory poker from the fresh concrete.
6. Repeat the procedure at all deployment locations.
