Vacuum Fan Off and Squeegee Up
The following conditions must be met for the Vacuum Fan to shut off and for the squeegee to be raised to the
travel position:
• The
Key Switch
must be on.
• The engine must be running.
• The scrub off mode must be selected or the vacuum system switched off at the
Dashboard Panel
, or the
drive pedal must be moved to the reverse position (squeegee will rise up).
The Vacuum Fan will shut off after a time delay once the drive pedal is in the neutral position. Note that
if the seat switch is open, the Vacuum Fan will run continuously (regardless of the drive pedal being in
neutral) to allow water pick-up with the Wand attachment.
