FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
Fig.1
Fig.2
Always switch off the tool before insertion or
•
removal of the battery cartridge.
To remove the battery cartridge, first open the
•
battery cartridge cover. To open the cover, press its
recessed part and pivot it with the recessed part
depressed. And then withdraw it from the tool while
sliding the button on the front of the cartridge.
To insert the battery cartridge, align the tongue on
•
the battery cartridge with the groove in the housing
and slip it into place. Always insert it all the way
until it locks in place with a little click. If you can
see the red part on the upper side of the button, it
is not locked completely. Insert it fully until the red
part cannot be seen. If not, it may accidentally fall
out of the tool, causing injury to you or someone
around you.
Do not use force when inserting the battery
•
cartridge. If the cartridge does not slide in easily, it
is not being inserted correctly.

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.

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.
