Brush Up/Down Switch (See Figure #1, Item “C”) The brush switch has two positions: “Up” positions the brushes up; “Down” positions the brushes on the ﬂ oor. The brush motors start when the brushes are down and the traverse switch is depressed.

Increase Brush Pressure Switch (See Figure #1, Item D) This switch is used to increase the brush pressure. Increased brush pressure may be required when stripping or cleaning heavily soiled ﬂ oors. To increase brush pressure, ﬁ rst lower the brushes by pressing the brush up/down switch (Item “C”) to the down position. This will lower the brushes to the normal scrub position. To increase brush pressure, press and hold the switch (Item “D”) until the desired brush pressure is reached or the brush deck stops moving downward. To reposition the brush pressure to normal scrub, press the brush up/down switch (Item “C”) to the up position and after the brush deck is completely raised, then return the switch to the down position for normal scrub.

Solution Control Knob (See Figure #1, Item “E”) The solution control knob regulates the ﬂ ow of cleaning solution to the ﬂ oor. To increase the ﬂ ow turn the knob clockwise. To decrease the ﬂ ow, turn the knob counter-clockwise.

Forward Switch (See Figure #1, Item “F”) The forward switch turns the traverse motor “on” and if the brush motors are in the down position, it also activates the brush motors and solution control module. Either the right or the left switch can be used.

Reverse Switch (See Figure #1, Item “G”) The reverse switch, when used in conjunction with one of the forward switches, causes the machine to reverse direction. The reverse speed is 70% of the forward speed.

Charge / Battery Meter (Solo) (See Figure #1, Item “H1”) The charge/battery meter indicates the battery is being charged when the charger is plugged into an AC outlet. It also indicates the amount of charge that is left in the batteries while the machine is in use. When the battery charger gets too low the red light will begin ﬂ ashing and the brush/pad motors will shut off.

Battery Meter / Charge Indicator Light (I-Drive) (See Figure #1, Item “H2”)

The battery meter indicates the amount of charge remaining in the batteries while the machine is in use. When the charger is plugged into an AC Outlet, the charge green indicator light will ﬂ ash on and off. When the batteries become fully charged, the green indicator light will remain on until the charger is unplugged.

Circuit Breakers (See Figure #1, Item “I”-”M”) The circuit breaker reset buttons are located on the control panel. The breakers are located as follows: Item I & J - Brush Motors (35A); Item K - Traverse Motor (30A); Item L - Vac Motor (25A); Item M - Actuator Motor, Brush Head (5A)

If a circuit breaker trips, determine which motor is not operating and turn the key switch “OFF”. Wait ﬁ ve minutes and push the reset button back in. Turn the key switch “ON”, and try again. An authorized service person should be contacted if the breaker trips again.

Hour Meter (See Figure #1, Item “N”) The hour meter indicates the number of hours the machine has operated. It runs only when the machine is moving forward or reverse.

Battery Maintenance

The electrical power to operate the machine comes from the storage batteries. Storage batteries need preventive 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” 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 ﬁ gure #7.

NOTE: Check the level of electrolyte prior to charging the batteries. Be sure the plates in each cell are covered with electrolyte . Do not top off the cells prior to charging the battery. Electrolyte expands during charging. As a result, the electrolyte could overﬂ ow from the cells. Always top off the cells with distilled water after charging.

CAUTION!

Irreversible damage will occur to the batteries if the electrolyte level 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 ﬁ lled above the bottom of the tube in each cell. Do not ﬁ ll 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.

Correct ﬁ ll level
