7. Stepping on the

Accelerator Pedal

turns on the

Transport,

Brushes, Water Flow, Vacuum

and

lowers the

Rear Squeegee

accordingly to the Mode selected. If the operator steps on the

accelerator pedal before, or turns the key switch “ON” at the same time, the machine will not move
as a safety precaution. Simply remove your foot off the pedal and step on the pedal again to drive
the machine. Please refer to the

Main Keyboard section

of this manual for a complete description of

the functions.

8. When

Reverse

is selected on the Directional Switch, the

Back-up Alarm

will be activated and the

Rear Squeegee

automatically is raised when you step on the accelerator pedal. However, the

Scrub brushes will continue to rotate and solution will continue to flow.

9. Start scrubbing by driving the machine forward in a straight line at 3/4 speed and overlap each path

by 2 to 3 inches. Adjust your speed; brush pressure and solution flow according to the condition of
the floor.

CAUTION!
To avoid any damage to the floor, keep the machine moving when the brushes are turned on.

10. When scrubbing, check behind the machine occasionally to see that all the dirty water is being

picked up. If streaking occurs, your

Water Flow

setting may be

too high

, the

Recovery Tank

may

full

, the

Squeegee hose

may be

clogged

, or the

Rear Squeegee

may require some

adjustment.

11. Make the necessary adjustments on the

Rear and Side Squeegees

if streaking occurs both in

straight paths and in turns. Pleas refer to the

Rear Squeegee

and

Side Squeegee

section of this

manual before making any adjustments.

12. In cases where the floors are extremely soiled and dirty, the

Double Scrub

mode may be needed.

As described in the

Main Keyboard section

of this manual, this mode allows the operator to be able

to scrub an area without recovering the cleaning solution with the rear squeegee in the raised
position (no vacuum) to allow the cleaning solution a longer time to loosen dirt. A final pass on the
same area is made with the mode switched over to either

Full Function

Vacuum Only

mode to

recover the dirty water.

13.

The recovery tank has two safeguards for overflow protection to guard against water from entering
the vacuum system when the recovery tank is full. When the

indicator light

is lit up in the

Keyboard

the

Vacuum icon

in the

LCD Screen

will be

flashing

(see the

LCD Display

section of this manual)

The vacuum will stay ON for 15 seconds and then shut-off automatically. A ball float shut-off system
has also been integrated into the Recovery Tank. When the dirty water reaches a certain level, the
ball gets suctioned into the vacuum manifold and blocks the airflow thus, preventing the machine
from picking up more liquid. When this happens, the operator is then required to stop scrubbing and
empty the recovery tank.

14. To stop scrubbing, select the

Transport mode

. This will automatically stop the

Solution Flow

raise the

Scrub deck

, and raise the

Rear squeegee

(there is a 15 second delay for the vacuum

motor).

15. Drive the SCV to a designated dirty water disposal area and empty the Recovery tank. To empty,

remove the

Drain hose

from its storage hanger. Unscrew the plug and hold the hose end above

the water level in the tank to avoid sudden, uncontrolled flow of dirty water. With the plug
completely off, carefully direct the water flow to the desired drain. Reinsert the plug and tighten and
return to its storage hanger.

16. The recovery tank should be rinsed out to remove solids in the tank. Open the

Cleanout cap

remove the

Stopper

plug.

Tilt the recovery tank (similar to accessing the batteries) and clean the

sludge that has settled in the sump area by either back flushing or by scraping it out. Be sure to
tightly secure the

Stopper

plug

and cleanout cap before continuing to operate the scrubber.

17. Refill the solution tank and continue scrubbing until the job is done or when the machine runs out of

power.

18. The

battery gauge bar icon

will flash to signal the operator that the machine is almost out of

power. Once this signal is displayed to the operator,

all functions will shut off

(brush will turn off and

the scrub deck will raise up, water flow will cease, the rear squeegee will raise up and the vacuum
motor will turn off) including the transport mode. The operator has to turn the

key switch OFF

and

then,

to reset

the machine. The machine then will only have a few minutes left of reserve

power for a short

Vacuum only mode

to pick up remaining solution on the floor and

Transport

power

to drive to the battery recharging station.
