Operation - Makita VR001G Instruction Manual

OPERATION

CAUTION:
Put the shoulder strap on the
shoulder, and hold the tool firmly with both
hands.
NOTICE:
At the very beginning of operation, the
flexible shaft tends to vibrate at a higher ampli-
tude. The tool will restore the normal amplitude
after you squeeze and release the switch trigger a
few times repeatedly.
Make sure to throw in and keep the vibration head stand straight
during operation. Use the tool within the effective vibration
ranges at equidistant intervals. The effective air bubble removal
range is approximately ten times the diameter of vibration head.

NOTICE:
Do not use the tool to move concrete
in the formwork. 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.
When using the tool on slope, always operate it from
the bottom at the beginning. If you operate the tool from
the top, the mortar will separate and eventually slide to
the bottom.

NOTE: Vibrating too long in a single place causes
concrete segregation.
NOTE: 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 condition.
