NOTICE: Do not use the tool to move concrete in the formwork. The mortar will just move away and the coarse aggregate will remain, causing segregation.

•  Fig.25

Effective leveling and removal of air bubbles

Removal of the air bubbles is complete after you have worked the tool throughout each effective range, the concrete stops shrinking, and the mortar has risen
evenly to the surface, giving off a light appearance.
Gently remove the operating tool not to leave holes.
When using the tool on slope, always operate it from the bottom at the beginning.
If you operate the tool from the top, the mortar will separate and eventually slide to the bottom.

• Fig.26
• Fig.27

NOTE: Vibrating too long in a single place causes concrete segregation.
NOTE: When the coarse aggregate segregates when placing concrete, shovel out the coarse aggregate and put it where there is plenty of mortar.
Then use the tool on it. Don’t leave coarse aggregate in the segregated condition.

•  Fig.28
