HOW THE MACHINE WORKS
USAGE
JVC56RIDERN is a ride-on industrial / com-
mercial machine used to scrub rough and
smooth
hard surfaces such as concrete, ceramic tile
floor, stone, and synthetic materials, etc. Typi-
cally, this machine is designed solely for clea-
ning smooth flooring in an indoor environment
like schools, hospitals/health care facilities,
office buildings, and marketplace, but it is not
allowed to use it on earth surface, grassland,
artificial turf, or carpeted areas, neither can it
be used for road cleaning. Any operation other
than those stated in the operator manual is not
recommended.
SCRUBBING METHOD
Water and detergent in solution tank flow to the brush and ground via the magnetic valve. The
solution of water and detergent is used to scrub the ground by brush head rotation. The squeegee
will take up the waste water into solution tank with vacuum motor while the machine is operating.
