INSTALLING THE BRUSHES OR PAD HOLDERS
1
Make sure the Brush Deck (14) is in the RAISED position.
2
If using pads, install the pads on the pad holders.
3
Place the brushes/pad holders under the raised Brush Deck (14). NOTE: brushes should be centered on the brush drive motors.
4
Turn the Master Key Switch (20) ON and push the Brush Install Button (35) to engage the brushes/pad holders.
NOTE: Brushes can also be installed and removed by manually turning them onto or off of the brush drivers.
INSTALLING THE SQUEEGEE
1
Loosen the thumb screws on top of the squeegee tool.
2
Hold the squeegee tool so the curved ends point toward the front of the machine.
3
Slide the squeegee tool onto the squeegee mount. Hand tighten the thumb screws - do not tighten them with a wrench or pliers.
4
Push the vacuum hose from the machine onto the vacuum tube on the squeegee.
FILLING THE SOLUTION TANK
Fill the solution tank with a maximum of 30 gallons (113 Liters). Do not fill the solution tank above 7.5 cm (3 inches) from the top of the tank. The solution should
be a mixture of water and the proper cleaning chemical for the job. Always follow the dilution instructions on the chemical container label.
CAUTION !
Use only low-foaming, non-flammable liquid detergents intended for machine application.
WET SCRUBBING
1
Follow the instructions in the Preparing The Machine For Use section of this manual.
2
Turn the Master Key Switch (20) ON. This will display the control panel indicator lights, reference the Battery Condition Indicator (17) and Hour Meter
(18).
3
Release the Operator Hand Brake (16).
4
Press the Solution Button (23) and hold for 5 seconds. This is done to pre-wet the floor. Note: This will help prevent scarring of the floor surface when
starting to scrub with dry brushes.
5
Press the Normal Scrub Button (29) for moderate scrub deck pressure or the Heavy Scrub Button (27) for the highest pressure mode. Note refer to the
machine control description section to the have more detailed explanation of this and other control panel functions.
6
When either the Normal Scrub Button (29) or Heavy Scrub Button (27) are selected, the brushes and squeegee automatically are lowered to the floor.
The machine’s scrub brushes rotation and solution system flow starts when the Drive Paddle (3) is activated.
7
When the Drive Paddle (3) is in the neutral position, the brushes do not run and solution is not dispensed. Grip the Operator Control Handle (15) and
push the Drive Paddle (3) forward to start the brush motor and the solution, and to move the machine forward. For best results, move the machine at
a slow walking speed. Push the Solution Button (23) to turn the solution OFF while making sharp turns. Pull the Drive Paddle (3) backward to move the
machine in reverse. The brushes will run while moving the machine in reverse, and solution will be dispensed.
8
Begin scrubbing by moving 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 flow according to the condition of the floor.
9
Adjust the Solution Flow Control Knob (10) so a thin, even layer of solution can be seen in front of the Squeegee (8). Note the adjustment can be changed
to allow variable solution flow for different types of floors to be scrubbed. Example: A rough or absorbent floor surface, such as unfinished concrete, well
require more solution than a smooth finished floor.
CAUTION !
To avoid damaging the floor, keep the machine moving while the brushes are turning.
10
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.
11
For extremely dirty floors, 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 first pass the squeegee is in the up position (press the Vacuum Button (25) to raise the pick up squeegee).
This allows the cleaning solution to remain on the floor to work longer. The final pass is made over the same area, with the squeegee lowered to pick
up the accumulated solution.
12
The recovery tank has an automatic float shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When the float shut-
off is activated, the control system will shut down the scrub, vacuum and solution systems. The Vacuum System Fault Indicator (24) will be lit and the
Hour Meter / Status Display (18) will display “FULL”. To clear the display, press the Scrub OFF Button (31). When the float closes, the recovery tank
must be emptied. The machine will not pick up water with the float 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 qualified service technician perform this function.
13
When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Button (31) once. This will automatically stop the scrub brushes
and solution flow and the scrub deck will raise UP. NOTE: the vacuum/squeegee system will not be turned off when the button is only pressed once,
this is to allow any remaining water to be picked up without turning the vacuum back on. Press the button a second time and the squeegee will raise and
the vacuum will stop after a 10 second delay.
14
Move the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, remove the Drain Hose (5) from it’s hanger,
then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). Refill the solution
tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (2) is properly seated or the machine will not pick-up water correctly.
