SCRUBBING

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.

Follow the instructions in preparing the machine for use section of this manual. Start the engine following the instructions in the appropriate
“Starting the … Engine” section (Engine models).

While seated on the machine, adjust the seat and steering wheel (tilt steering is optional) to a comfortable operating position.

Release the Parking Brake

(38)

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

(37)

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

Press and hold the Solution Switch

(U)

to pre-wet the

oor, solution will be dispensed while the switch is held.

NOTE:

This will help prevent scarring

of the

oor surface when starting to scrub with dry brushes. This must be done prior to pressing the One-Touch™ Scrub Switch

(R)

Pre ss the One-Touch™ Scrub Switch

(R)

, the scrub deck and squeegee will automatically be lowered to the

oor. The scrub, vacuum, solution and

detergent (EcoFlex models) systems all start when the Drive Pedal

(37)

is activated.

The scrub pressure will default to Normal (one scrub pressure indicator lit). Use the Scrub Pressure Increase Switch

(Q)

and Scrub Pressure

Decrease Switch

(S)

to change between Normal, Heavy and Extreme Scrub modes. The solution

ow rate will automatically adjust to coincide with

the scrub pressure.

NOTE:

The solution

ow rate can be changed independently of the scrub pressure simply by pressing the Solution Flow Increase

(T)

or Solution

Flow Decrease Switch

(V)

. Any subsequent scrub pressure adjustments will reset the solution

ow rate to correspond with the scrub pressure.

NOTE:

The scrub, solution, vacuum, detergent (EcoFlex models) systems are automatically enabled when the One-Touch™ Scrub Switch

(R)

pressed. Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.

NOTE:

When operating the machine in reverse the squeegee automatically raises and the solution

ow will stop.

Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3” (5.08-7.62cm). Adjust the
machine speed and solution

ow when necessary according to the condition of the

oor.

CAUTION!

To avoid damaging the

oor, keep the machine moving while the brushes are turning (the brushes will turn OFF after a 2 second

delay when the drive pedal is placed in the neutral position).
Raise scrub deck when crossing speed bumps.

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.

The machine defaults to the last cleaning mode used

Minimum or Maximum Concentration Detergent

(if detergent is installed). Press the Burst of

Power Switch

(P)

to override the current cleaning mode and temporarily increase scrub pressure, solution

ow and the detergent percentage (unless

Maximum Concentration

). This will cause the indicator to

ash for one minute, solution

ow rate will increase to the next level, scrub pressure will

increase to the next level and the detergent percentage will be at the Maximum Concentration level (detergent system will be turned on if it was off).

NOTE:

Pressing and holding the Burst of Power Switch

(P)

for 2 seconds changes between the

Minimum

and

Maximum Concentration

operating

modes. The EcoFlex system will only function if the scrub system has been enabled.

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/Wand Switch

(W)

to raise the

squeegee). This allows the cleaning solution to remain on the

oor to work longer. The Side Skirts

(8 & 39)

can also be raised for double scrubbing

if needed and held in place with the catch

(AE)

shown in Figure 4. The

nal pass is made over the same area, with the squeegee and skirts lowered

to pick up the accumulated solution.

The recovery tank has two shut-off

oats

(52)

that cause ALL systems to turn OFF except the drive and sweeping systems when the recovery tank

is full. When the

oat(s) is activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the

oat activated. The

machine can continue to be used for sweeping.

NOTE:

The Warning Indicator

(J)

will light up RED and the Recovery Full Icon

(C22)

will display when the shut-off

oat

(52)

is activated. If the control

repeatedly gives a full indication when the tank is not full check to make sure the

oats move freely.

10 When the operator wants to stop scrubbing, press the One-Touch™ Scrub Switch

(R)

once. This will automatically stop the scrub brushes, solution

ow and detergent

ow. The scrub deck will raise up. The squeegee will raise up after a brief delay and the vacuum will stop after a brief delay (this

is to allow any remaining water to be picked up without turning the vacuum back on).

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

(7)

from its storage area, then unscrew the cap (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled

ow of waste

water). The Recovery Tank Drain Hose

(7)

can be squeezed to regulate the

ow. Re

ll the solution tank and continue scrubbing.

NOTE:

Make sure the Recovery Tank Lid

(5)

and the Recovery Tank Drain Hose

(7)

cap are properly seated or the machine will not pick-up water

correctly.

Battery Models:

When the batteries require recharging the Battery Low Indicator

(C12)

will be displayed. Then the scrub and sweep systems will

automatically shut down. Transport the machine to a service area and recharge the batteries according to the instructions in the maintenance section of
this manual.
