OPERATING THE MACHINE

WARNING!

Be sure you understand the operator controls and their functions.

While on ramps or inclines, avoid sudden stops. Avoid abrupt sharp turns. Use low speed down ramps. Clean only while

descending (driving down) the ramp.

To Scrub...

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

See Figure 6. Adjust the Operator's Seat (1) if necessary by tipping up the seat and using the Seat Adjustment Knob (16).

Turn the Key Switch (A) ON (I). This will display the control panel indicator lights. Reference the Battery Indicator (F4) before proceeding.

To transport the machine to the work area, ﬁ rst push the Forward / Reverse Switch (C) to select "reverse" if backing up and then apply pressure with your foot

on the Drive Pedal (3). Reverse Mode is indicated by the Reverse LED (B) glowing Amber and an audible alert from the horn.

Press and hold the Solution Control Switch (O) to pre-wet the ﬂ oor, solution will be dispensed while the switch is held. NOTE: This will help prevent scarring

of the ﬂ oor surface when starting to scrub with dry brushes. This can only be done prior to pressing the Scrub ON/OFF Switch (M).

Press the Scrub ON/OFF Switch (M), the scrub deck and squeegee will automatically be lowered to the ﬂ oor. The scrub, vacuum, solution and detergent

systems all start when the Drive Pedal (3) is activated. NOTE: If the detergent is OFF when the machine is turned OFF it will remain OFF when the machine

is turned ON again.

The scrub pressure will default to LOW (bottom Brush Pressure LED (J) lit). Use the Brush Pressure Increase Switch (K) and Brush Pressure Decrease

Switch (I) to change between LOW, MEDIUM and HIGH Scrub modes.

NOTE: The solution ﬂ ow rate can be changed independently of the scrub pressure by pressing the Solution Control Switch (O).

NOTE: The scrub, solution, vacuum and detergent systems are automatically enabled when the Scrub ON/OFF Switch (M) is pressed. The vacuum

system can be turned OFF or back ON by simply pressing its switch (Q) at any time during scrubbing. The Solution System can only be turned OFF by

cycling through all solution ﬂ ow rates until no LEDs (N) are lit. The Scrub System can only be turned OFF by pressing the Scrub ON/OFF Switch (M). The

Detergent System can only be turned OFF by cycling through all detergent ratios to the last ratio 1:400 and then pressing the Detergent Control Switch (S)

one more time.

NOTE: When operating the machine in reverse the squeegee automatically raises.

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 the

machine speed, scrub pressure and solution ﬂ ow when necessary according to the condition of the ﬂ oor. NOTE: The maximum speed can be varied by

pushing the Speed Increase Switch (E) or the Speed Decrease Switch (D) which will be indicated by the Speed Indicator (F6).

CAUTION!

To avoid damaging the ﬂ oor, only start and stop the scrubbing function while the machine is in motion.

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 ﬂ 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 ﬁ rst pass the squeegee is in the up position (press the Vacuum ON/OFF Switch (Q) to raise the squeegee).

This allows the cleaning solution to remain on the ﬂ oor to work longer. The ﬁ nal pass is made over the same area, with the squeegee lowered to pick up the

accumulated solution.

The recovery tank has a shut-off ﬂ oat (25) that causes a change in pitch in the vac motor. When this ﬂ oat is activated, the recovery tank must be emptied.

The machine will not pick up water with the ﬂ oat activated.

When the operator wants to stop scrubbing:

Press the Scrub ON/OFF Switch (M) once. This will automatically stop the scrub brushes and solution ﬂ ow and 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).

Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (28) from

its rear storage area, then unscrew the cap (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled ﬂ ow of waste water).

Inspect and empty the Strainer Basket (26) in the recovery tank. Reﬁ ll the solution tank and continue scrubbing.

NOTE: Make sure the Recovery Tank Cover (24) and the Recovery Tank Drain Hose (28) cap are properly seated or the machine will not pick-up water correctly.

When the batteries require recharging the Battery Low Indicator (F7) will come on. Then the scrub brushes and solution ﬂ ow will stop and the scrub deck will raise

up. The squeegee will raise up after a brief delay and the vacuum will stop after a brief delay. Transport the machine to a service area and recharge the batteries

according to the instructions in the Battery section of this manual.
