CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch lever actuates
properly and returns to the "OFF" position when
released.
To start the tool, simply pull the switch lever. Release the
switch lever to stop.
Switch lever can be pulled from either top or back side of
the tool.

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 aggregate will
remain, causing segregation. (Fig. 5)
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 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.

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 effective
removal of air bubbles. Conversely, if the pouring is done
first from above, the mortar will separate and eventually
slide to the bottom. (Fig. 6)

MAINTENANCE

• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
