MACHINE CONTROL PANEL
Key Switch (See Figure 1, Item “A”)
The key switch turns “ON” the power to the control panel. “O” is “OFF” and “I” is “ON”.
Traverse Speed Switch (See Figure #1, Item “B”)
The speed control varies from low to high speed. To increase the speed, turn the knob to the right. To decrease the speed, turn the knob to the left.
One Touch Control Button (See Figure 1, Item “C”)
The one touch control button raises and lowers the brush head assembly, starts and stops the vacuum motor automatically. Press the one touch control button once and the brush head assembly lowers to the floor and the vacuum motor turns “ON” (brush head and vacuum LEDs illuminate green). The brush motors start when the brushes are down and the forward palm button is depressed. Press the one touch control button again and the brush head assembly raises, the vacuum motor will remain on for 10 seconds and then shut “OFF”.
Increase Brush Pressure Button (See Figure 1, Item D)
This button is used to increase the brush pressure. Increased brush pressure may be required when stripping or cleaning heavily soiled floors. To increase brush pressure, first lower the brushes by pressing the one touch control button (Item “C”). This will lower the brushes to the normal scrub position. To increase brush pressure, press the button (Item “D”). The LED above the button will illuminate yellow. Press the button (Item “D”) again and the brushes will return to normal scrub (yellow LED will turn “OFF”). NOTE: Increase brush pressure is not available on cylindrical machine.
Vacuum Motor Button (See Figure 1, Item “E”)
The vacuum motor button turns the vacuum motor “ON” or “OFF”, regardless of brush head assembly position. The green LED will illuminate when the vacuum motor is “ON”.
Solution Control Buttons (See Figure 1, Item “F & G”)
The solution control buttons regulate the flow of cleaning solution to the floor. The normal scrub solution setting is indicated by two green bars on the meter. On cylindrical machines, with most floor conditions, the solution setting should be set one step higher. To increase the flow, press the solution flow button “G” (+) until the desired flow is reached. To decrease the flow, press the solution flow button “F” (-) until the desired flow is reached. To shut off the solution, press the solution flow button “F” (-) until no indicators are visible on the display. NOTE: No solution will flow when the machine does not traverse.
Forward Palm Buttons (See Figure 1, Item “H”)

Battery Maintenance
The electrical power to operate the machine comes from the storage batteries. Storage batteries need preventative maintenance.
WARNING: |
Working with batteries can be dangerous. |
|
Always wear eye protection and protective |
|
clothing when working near batteries. NO |
|
SMOKING! |
To maintain the batteries in good condition, follow these instructions:
1.Keep the electrolyte at the correct level. The correct level is between 1/4” (1/2 cm) below the bottom of the tube in each cell and above the tops of the plates. Check the level of the electrolyte each time you charge the batteries. See figure 6.
NOTE: Check the level of electrolyte prior to charging the batteries. Be sure the plates in each cell are covered with electrolyte before charging. Do not top off the cells prior to charging the battery. Electrolyte expands during charging. As a result, the electrolyte could overflow from the cells. Always top off the cells with distilled water after charging.
CAUTION: |
Irreversible damage will occur to the batteries if |
|
electrolyte does not cover the plates. Keep the |
|
electrolyte at the correct level. |
CAUTION: |
Machine damage and discharge across the tops of |
|
the batteries can occur if the batteries are over filled. |
|
Do not fill the batteries up to the bottom of the tube |
|
in each cell. Wipe any acid from the machine or the |
|
tops of the batteries. Never add acid to a battery after |
|
installation. |
CAUTION: |
Batteries must be refilled with distilled water only. Do |
|
not use tap water as it may contain contaminants that |
|
will damage batteries. |
2.Keep the tops of the batteries clean and dry. Keep the terminals and connectors clean. To clean the top of the batteries, use a damp cloth with
aweak solution of ammonia or bicarbonate of soda solution. To clean the terminals and connectors, use a terminal and connector cleaning tool. Do not allow ammonia or bicarbonate of soda to get into batteries.
3.Keep the batteries charged.
4.To drain battery compartment: (See figure 7)
a.Always wear protective eye protection and protective clothing.
b.Add a weak solution of ammonia or bicarbonate of soda solution to battery compartment to neutralize any spilled acid.
c.Locate drain hose behind the transaxle.
d.Place hand behind flange and open valve.
e.When empty, close valve.
f.Neutralize any acid spills with ammonia or bicarbonate of soda.
