Machine Overview

1.4 Control Console

For operator ergonomics, the control

console houses all the primary function

controls in a central area. The key

switch and optional headlight and off-

aisle wand switches are clustered in

the back portion of the console. The

directional switch (forward/reverse) is

located at the front of the console for

easy fingertip operation. The horn but-

ton, function selectors, and battery

gauge are located in the central part of

the console.

Key Switch (A) - S2

Controls the machine’s power (ON/

OFF) with a key for safety. All opera-

tional settings are retained even when

the power is turned off and on. This

also serves as a reset switch when

errors or faults occur.

Off Aisle Wand Switch (OPTIONAL)

(B) - S7 (281900 OPTIONAL)

ON/OFF control for the water supply to

the wand and vacuum motor for the

optional Off-Aisle Wand.

Headlight Switch (OPTIONAL) (C) -

S10 (281990 OPTIONAL)

ON/OFF control for the optional head-

lights.

Battery Gauge (D) - BD1

Displays the level of charge remaining

in the machine’s batteries. The gauge

consists of 10 LEDs. (3 Green, 4

Amber, 3 Red) If the battery life is low,

the battery gauge bar icon will be flash-

ing to inform the operator that the

machine is almost out of power. Once

17

Machine Overview

this signal is displayed, all functions will shut off, including

transport mode. The operator must then turn the key switch

OFF and then ON to reset the machine. The machine will

then have only a few minutes left of reserve power to briefly

use Vacuum Only mode to pick up any remaining solution on

the floor and Transport mode to return to the charging sta-

tion. This gauge will also display a fault code if the system

has an error. This code is represented by a specific number

of flashing LEDs. See Fault/Diagnostic Codes for specific

code information.

Solution Control Knob (E) - R2

Adjusts the amount of solution being dispensed to the floor

while in one of the scrub modes. Turn the knob clockwise to

increase the amount of solution being dispensed. The

amount of solution applied is variable to a maximum of 1

GPM.

Mode Selector Knob (F) - S4

This knob is used to select the desired operation mode of the

machine. See Operation Modes for information about each

mode.

Horn Button (G) - S3

Depressing this button will activate the machine’s horn.

Directional Switch (H) - S6

Pressing switch to the down position will set the machine to

move forward. Pressing it to the up position sets the machine

to move in reverse.

18

Machine Overview

1.5 Operation Modes

1. Regular Scrub Mode

When the machine is running in this mode, the machine will perform

all operations. This mode can be used for day-to-day tasks under nor-

mal conditions. When the operator sets the directional switch to for-

ward and activates the accelerator pedal, the solution pump will turn

on, the brushes will turn on and be lowered to the floor, as well as the

rear squeegee. While operating in this mode, the solution will be dis-

persed into the brushes, which will scrub the floor allowing the chem-

ical in the solution to break down the dirt on the floor. As the machine

continues to move forward, the rear squeegee and vacuum system

will recover the dirt and dispensed solution. If the operator stops mov-

ing, the machine will automatically raise the scrub deck and turn off

the brushes. If the directional switch is changed to reverse the ma-

chine will continue to operate normally, only the rear squeegee will

raise up.

2. Heavy Scrub Mode

This mode is similar to Regular Scrub. The machine will continue to

operate the same was as if it was in Regular Scrub Mode, only this

mode applies more solution and brush pressure is increased. This

mode is used for high traffic areas and areas that have been heavily

soiled, but do not require time for the solution to soak.

3. Double Scrub Mode

When the machine is running in this mode, the machine will perform

all operations except dirty solution recovery. This mode can be used

if the floor is heavily soiled and the chemical will need additional time

to emulsify grease and oils that are on the floor. When the operator

sets the directional switch to either the forward or reverse position

and activates the accelerator pedal, the solution pump will turn on,

the brushes will turn on and be lowered to the floor. While operating

in this mode, the solution will be dispersed into the brushes, which will

scrub the floor allowing the chemical in the solution to break down the

dirt on the floor. As the machine continues to move forward or back,

the rear squeegee and vacuum system are not on, which allows the

solution to stay on the floor emulsifying the grease and oil. If the op-

erator stops moving in either direction, the machine will automatically

raise the scrub deck and turn off the brushes. After double scrubbing,

the operator should use the vacuum only mode to recover the dirty

solution water from the floor.

4. Vacuum Only Mode

When the machine is running in this mode, the machine will only low-

er the rear squeegee and turn on the vacuum system to recover the

dirty solution from the floor. This mode is usually chosen after double

scrubbing to recover the dirty solution but it can also be used to pick

up spills. When the operator sets the directional switch to forward, the

rear squeegee will be lowered to the floor as the vacuum turns on,

pulling the dirty solution water from the rear squeegee into the recov-

ery tank. If the operator stops moving forward and sets the directional

switch to reverse, the rear squeegee will retract (protecting it from

damage) and the vacuum motor will turn off after a few seconds. If the

operator quits moving in either direction, the machine will automati-

cally raise the squeegee and turn off the vacuum motor after a few

seconds.

5. Transport Mode

When the machine is set in this mode, none of the cleaning functions

of the machine will operate. This mode is only used to transport the

machine from one location to another.

6. Solution Control Knob

This control will adjust the amount of solution that is being dispersed

to the floor while in one of the scrub modes. Adjust the control clock-

wise to increase the amount of solution being dispersed. The amount

of solution applied is variable to a maximum of 1 GPM.

7. Battery Gauge

This gauge displays the level of charge remaining in the machine’s

batteries. The gauge consists of 10 LEDs. (3 Green, 4 Amber, 3 Red)

If the battery life is low, the battery gauge bar icon will be flashing to

inform the operator that the machine is almost out of power. Once this

19

Machine Overview

signal is displayed, all functions will shut off, including transport

mode. The operator must then turn the key switch OFF and then ON

to reset the machine. The machine will then have only a few minutes

left of reserve power to briefly use Vacuum Only mode to pick up any

remaining solution on the floor and Transport mode to return to the

charging station. This gauge will also display a fault code if the sys-

tem has an error. This code is represented by a specific number of

flashing LEDs. See Fault/Diagnostic Codes for specific code informa-

tion.

20

Machine Overview

1.6 Fault/Diagnostic Codes

When an error or fault occurs within the machine, a fault code will ap-

pear on the battery gauge represented by a specific number of flash-

ing LEDs. The figure below shows a listing of the different codes.

Low Battery Indicator

If the battery life is low, the battery gauge bar icon will be flashing to

inform the operator that the machine is almost out of power. Once this

signal is displayed, all functions will shut off, including transport

mode. The operator must then turn the key switch OFF and then ON

to reset the machine. The machine will then have only a few minutes

left of reserve power to briefly use Vacuum Only mode to pick up any

remaining solution on the floor and Transport mode to return to the

charging station.

Power Save Mode

The E Ride is equipped with a power save feature to conserve battery

power. If the key switch power is left ON and none of the controls are

activated for a period of fifteen minutes, the E Ride automatically

goes into “power down mode” and turns OFF the power to conserve

your batteries in case the operator forgets to turn the key switch off or

leaves the machine unattended.

Empty Solution Tank Indicator

Once the solution tank has become empty, the battery gauge will

blink a solid 9 LEDs at a constant interval to alert the operator that the

solution tank needs to be filled.
