CAUTION:
Always switch off the tool before installing or
•
removing of the battery cartridge.
Hold the tool and the battery cartridge firmly

when installing or removing battery cartridge.
Failure to hold the tool and the battery cartridge
firmly may cause them to slip off your hands and
result in damage to the tool and battery cartridge
and a personal injury.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip it
into place. Insert it all the way until it locks in place with a
little click. If you can see the red indicator on the upper
side of the button, it is not locked completely.
CAUTION:
Always install the battery cartridge fully until the red
•
indicator cannot be seen. If not, it may accidentally
fall out of the tool, causing injury to you or someone
around you.
Do not install the battery cartridge forcibly. If the
•
cartridge does not slide in easily, it is not being
inserted correctly.

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 (9-27/32").
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.
