vacuum, and solution systems. The hour meter/status display (A) will scroll the word “FULL” to indicate that the tank is full.
•Pressing the scrub-off/pressure-decrease, scrub-on/pressure-increase, or vacuum buttons will clear the full indication.
• The automatic vacuum shutoff feature can be disabled if the vacuum shuts off even when the tank is not full. Refer to the Electrical System
Main Control Board Special Program Options to disable.
System Overload Indications:
• If the scrub motors or the scrub deck lift actuator become overloaded, the scrub and solution systems will turn off and the scrub-off/pressure-
decrease indicator will flash red at a fast rate (four times per second).
• If the vacuum motor becomes overloaded, the scrub, vacuum, and solution systems will turn off and the vacuum indicator will flash yellow
at a fast rate (four times per second).
