OPERATING THE MACHINE

WARNING!

Be sure you understand the operator controls and their functions.
While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills. Clean only
while ascending (driving up) the ramp.

To Scrub...

Follow the instructions in preparing the machine for use section of this manual.
1

While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls

(25)

and

(5)

Turn the Master Key Switch

(J)

ON (I). This will display the control panel indicator lights, reference the Battery Condition Indicator

(K)

and Hour Meter

(G)

Release the Parking Brake

(6)

. To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal

(8)

to go

forward or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.

Adjust the Solution Flow Control Valve Lever

(7)

to about 1/4 to 1/3 open position

(Non EDS models).

Press the Flow Rate Switch

(T)

to select a solution

ow rate

(EDS models)

The

ow rate can be changed to allow variable solution

ow for different types of

oors to be scrubbed. Example: A rough or absorbent

oor surface

such as un

nished concrete, will require more solution than a smooth

nished

oor.

NOTE (Non EDS Models):

For a consistent reduced

ow of solution; open the Solution Flow Control Valve Lever

(7)

all the way and then turn ON the

ECO Solution™ Valve

(26)

. When the lever is in the “OFF” position; the machine operates conventionally; solution

ow is determined by the Solution

Flow Control Lever

(7)

. When the lever is in the “ON” position; solution

ow is controlled automatically. The Solution Flow Control Lever

(7)

should not

be shut off, but is otherwise inactive. Make sure that the lever for Valve

(26)

is all the way ON or all the way OFF, never in between. If more solution is

needed, turn OFF the ECO Solution™ Valve

(26)

and adjust the solution

ow with the Solution Flow Control Valve Lever

(7).

NOTE:

The solution, vacuum and detergent (EDS models) systems are automatically activated when the Scrub Pressure Decrease Switch

(D)

or the

Scrub Pressure Increase Switch

(F)

is pressed. No further action is required. Any individual system can be turned OFF or back ON by simply pressing

its switch at any time during scrubbing.

Press and hold the Solution Switch

(R)

for 5 seconds to pre-wet the

oor.

NOTE:

This must be done prior to pressing the Scrub ON Switch

(F)

When the Scrub Pressure Decrease Switch

(D)

or the Scrub Pressure Increase Switch

(F)

is selected, the brushes and squeegee are automatically

lowered to the

oor. The machine’s scrub brush rotation, solution system

ow, vacuum and detergent (EDS models) starts when the Drive Pedal

(8)

activated. Note: When operating the machine in reverse, only the brushes will rotate, the solution and detergent (EDS models) is automatically shut off
to conserve usage.

Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Adjust
when necessary the machine speed and solution

ow according to the condition of the

oor.

CAUTION!

To avoid damaging the

oor, keep the machine moving while the brushes are turning.

When scrubbing, check behind the machine occasionally to see that all of the waste water is being picked up. If there is water trailing the machine, you
may be dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.

For extremely dirty

oors, a one-pass scrubbing operation may not be satisfactory and a “double-scrub” operation may be required. This operation is

the same as a one-pass scrubbing except on the

rst pass the squeegee is in the up position (press the Vacuum Switch

(O)

to raise the squeegee).

This allows the cleaning solution to remain on the

oor to work longer. The

nal pass is made over the same area, with the squeegee lowered to pick

up the accumulated solution.

10 The recovery tank has an automatic

oat shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When the

oat shut-off is activated, the control system will shut down the scrub, vacuum, solution and detergent (EDS models) systems. The Scrub Pressure /

Hourmeter Display

(G)

will display “FULL”. To clear the display, press the Scrub OFF Switch

(B)

, Scrub Pressure Decrease Switch

(D)

, Scrub Pressure

Increase Switch

(F)

or the Vacuum Switch

(O)

. When the

oat closes, the recovery tank must be emptied. The machine will not pick up water with

the

oat closed.

NOTE:

If the control repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a

quali

ed service technician refer to the service manual to perform this function.

11 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch

(B)

once. This will automatically stop the scrub

brushes and solution

ow and the scrub deck will raise UP.

NOTE:

the vacuum/squeegee system will not be turned off when the switch is only pressed

once, this is to allow any remaining water to be picked up without turning the vacuum back on. Press the switch a second time and the squeegee will
raise and the vacuum will stop after a 10 second delay.

12 Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose

(21)

from its rear

storage area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled

ow of waste water). Re

the solution tank and continue scrubbing.

WET VACUUMING

Steps to follow in

tting the machine with optional attachments for wet vacuuming.

Disconnect the recovery hose from the squeegee. Connect the coupler and hose from the wand kit to the recovery hose.

Attach suitable wet pick-up tools to the hose. (An optional Wand Kit PN56314307 is available from Nil

sk).
