the switch lever to stop.

OPERATION

Hold the tool straight when inserting/operating. Use the tool
within the effective vibrations range at equidistant intervals.
The effective air bubble removal range is about ten times
diameter of the vibrating head, or around 250 mm.
Do not use this tool to move concrete within a form.
The mortar will just move away and the coarse aggre-
gate will remain, causing segregation.
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.
NOTE:
• Vibrating too long in a single place causes
concrete segregation.
• When the coarse aggregates segregates when
placing concrete, shovel out the coarse aggre-
gate and put it where there is plenty of mortar.
Then use the tool on it. Don't leave coarse
aggregate in the segregated condition.
When concreting a slope site, always pour from the
bottom at the beginning. This way the weight of the
freshly poured concrete and vibration will lead to effec-
tive removal of air bubbles. Conversely, if the pouring
is done first from above, the mortar will separate and
eventually slide to the bottom.
