OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, open the cover and
withdraw the battery cartridge from the tool while
pressing the buttons on both sides 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 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.
Switch action (Fig. 2)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the “OFF” position when released.
To start the tool, simply pull the trigger. Release the trig-
ger to stop.
Operation (Fig. 3)
Hold the tool straight when inserting/operating. Use the
tool within the effective vibration range at equidistant
intervals. The effective air bubble removal range is about
ten times the diameter of the vibrating head, or around
250 mm with this tool.
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 con-
crete 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 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 condi-
tion.
When concreting a slope site, always pour from the bot-
tom at the beginning. This way the weight of the freshly
poured concrete and vibration will lead to effective
removal of air bubbles.
(Fig. 4)
Conversely, if the pouring is done first from above, the
mortar will separate and eventually slide to the bottom.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work on
the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
