Maintenance - Makita VR004G Instruction Manual

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.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
NOTICE:
Avoid cleaning the tool in water. Water
will get into the motor housing and cause motor
failure.
NOTICE:
Use a wet cloth or the like to carefully
wipe off any wet concrete left on the tool after
use. Extra care should be given to thorough
cleaning of the vents, switch area, cover open-
ings, etc.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
