HOW THE MACHINE WORKS
USAGE
JVC70RIDERN is a ride-on industrial/commer-
cial machine used to scrub rough and smooth
hard surfaces such as concrete, ceramic tile
floor, stone, synthetic materials, etc. Typically
this machine is designed solely for cleaning
smooth flooring in an indoor environment like
schools, hospitals/health care facilities, office
buildings, and marketplace. 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 recom-
mended.
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.
CLEANING BRUSHES AND PADS
The solution tank, brush, pad holder and/or pad, squeegee, vacuum motor, recovery tank and drive
motor must be cleaned.
Brushing function is controlled by the buttons on the control panel. Turn on brush motor switch and
squeegee lifting switch, lay the brush and squeegee down. Set forward/backward switch to "forward"
position, adjust the speed switch appropriately (turn the switch to proper speed and water yield
based on different types of ground).
Release the manual brake and depress the pedal to start washing. There are two brushes available,
and the width of brush head is 350 mm (13 inches).
NOTE: The type of brush head or cleaning pad is determined by the quantity and type of
contamination particles and type of dirt. For special suggestions, please refer to the brush
information section of this manual or contact the Johnny Vac service team.
BRUSH INFORMATION
For best results, use the appropriate type of brushes for scrubbing. Recommended brushes and
pads are listed as follows:
Synthetic resin brushes - Soft synthetic resin brushes are generally used to scrub particles without
scratching the lighted side finishes of the floor and ground.
Nylon brush - The nylon brush is recommended for scrubbing floors without scratching them.
Pad holder and pad - It is used to scrub floor and painted ground to make it bright and clean.
Attached information:
• Pad holder and pad: 350 mm, 13 inches pad holder.
• Brush model: 350 mm, 13 inches brush.

COMPONENTS INSTALLATION
BATTERY INSTALLATION
1. Check each battery for damage, cleanliness and visible marks before use. Clean the surface of the
battery with a dry cloth, check the battery cells for open circuit voltage, whether the anode/cathode
are properly identified and whether they are properly connected.
2. Make sure each battery is fixed uprightly without inversion in accordance with drawings; interval
between two neighboring battery cells should be at least 5 mm. Check whether the anode/cathode is
correct according to the drawings after installation, then connect the battery cells with cables.
3. Check each part of all the battery cells for looseness after installation. DO NOT tighten the joints
with excessive force in case of damages to poles.
4. When fixing the whole set of battery cells to the machine, adjust the chocks between two
neighboring battery cells to make sure all the battery cells stand uprightly. Tighten the battery to
avoid shock or bumping.
5. Isolate the components that generate sparks such as main switch, fuse holder, etc from the battery
cells.
6. The battery cells can be fixed to the machine directly since they are at the state of charge before
delivery; when out of service for a long period (more than 2 months), please recharge the battery
cells before use.
7. Keep batteries away from fire , heat, or direct sunlight during summer, nor can the battery cells be
shocked or bumped violently, or short-circuited.
8. Battery capacity is measured at an environment temperature of 25°C . The capacity will drop by
1% every 1°C the temperature declines. So take the impact temperature variation into consideration
during use. DO NOT use batteries when the temperature declines below -10°C.
9. No arbitrary disassembly of battery is allowed in case of danger.
10. Waste batteries must be recycled. DO NOT abandon them to avoid pollution to the environment.
11. Notice battery temperature when charging in case of danger and damages to the batteries cause
by excessive heat.
12. DO NOT use batteries at insufficient voltage. Charge the batteries to full capacity before using.

2. Turn the ON/OFF key switch off.
FOR SAFETY: Stop the machine on a level surface and turn it off before leaving or servicing.
3. Method for replacing (installing) brush and pad holder: there are two sets of brushes, pad
holders, and cleaning pads at the left and right bottom of machine, hold the left brush with both
hands and turn it counterclockwise to remove it; hold the right brush with both hands and turn it
clockwise to remove it. Do it reversely when installing the brushes.

- 14 - User GuideJVC70RIDERN
COMPONENTS INSTALLATION
The machine is equipped with brushes and cleaning pads. Check scrub brushes every day for wire
or string wrapped around the brush or brush drive hub. Check for brush damage or wear.
FOR SAFETY: Stop the machine on a level surface, turn it off, and remove the key before leaving or
servicing.
Scrub brushes shall be replaced if a great number of bristles are missing or bristle length is less
than 10 mm (0.38 inch).
Cleaning pads must be fixed on the pad drive hubs before using. Pad holder is used to fix the pad.
Cleaning pads must be cleaned immediately with soap or water after using. DO NOT wash them with
pressure washer. Hand the pads or lay them flat to dry.
NOTE: Replace the brushes and pads in whole sets, otherwise on brush or pad will be more
aggressive than the other.

FILL SOLUTION TANK
FOR SAFETY: Stop the machine on a smooth surface when leaving or servicing it, turn it off and remove
the key.
The water injection hole for solution tank is located at the back of machine.
WARNING:
DO NOT use flammable materials in the tank in case of explosion or fire.
Scrubbing method: Open water injection hole of solution tank and inject some water (water temperature
should not be higher than 60°). Pour the detergent into tank based on the mixture ratio specified on tank.
Fill warm water into the tank. Defoamer is needed in recovery tank (please refer to the mixture ratio on the
package).
FOR SAFETY: When using machine, follow mixing and handling instructions on chemical containers.
NOTE: When filing the solution tank with a bucket, make sure it is clean.
DO NOT use the same bucket for
filling and draining he machine.
ATTENTION: For conventional scrubbing, only use recommended cleaning detergents. Machine damage
due to improper detergent usage, such as washing powder, will void the manufacturer's warranty.

MACHINE OPERATION
DURING OPERATION
• Drive as straight as possible on your layout. Avoid hitting posts or rubbing the sides of the
machine. Overlap brushing patterns by several centimeters (inches).
• Avoid turning the steering wheel substantially since the machine is sensitive to steering wheel rota-
tion. Avoid sudden turning unless emergency.
• Adjust machine speed and water flow as needed during scrubbing. Keep driving at a moderate
speed with minimum water flow.
• Keep the machine running to avoid damages to the ground.
• If poor scrubbing performance is observed, stop scrubbing and refer to troubleshooting.
SCRUBBING METHOD
• Pour a recommended foam control solution into recovery tank if excessive foam occurs. Otherwise
the vacuum motor may be damaged if the foam is sucked into the motor.
• Change the pad holder or cleaning pad as necessary for better scrubbing performance.
• Observe the battery indicator to ensure there is adequate power for machine to operate.
• Observe the solution tank indicator to ensure the solution does not run out. Please clean the tank
before refilling.
• Remove the key when leave the machine unattended.
• Perform daily maintenance after scrubbing (see Maintenance Form).
• Drive the machine slowly on inclines: press brake pedal to control the machine and turn down
speed switch when driving down. Do scrubbing when machine goes upward instead of downward.
FOR SAFETY: Drive slowly when using machine on inclines or smooth surfaces.
DO NOT operate the machine in areas where the temperature exceeds 43°C (110°F).
Scrubbing function cannot be used in areas where the temperature is lower than 0°C (32°F).
Maximum rated slope is 7% during operation. Maximum rated inclination for transporting the
machine is 19.25%.

WATER GAUGE TUBE OF SOLUTION TANK
Water gauge tube of solution tank can roughly indicate the real-time water level so as to ensure
proper operation of machine.
Water level of solution tank is suggested to be kept above half the height of water gauge tube to
guarantee water pressure and water flow.
