WET VACUUMING

Steps to follow in fitting the machine with optional attachments for wet vacuuming.
1 Disconnect the recovery hose connection at the recovery tank inlet. Then fit a 1-1/2 inch (38 mm) Dia. vacuum hose to the recovery inlet.
2 Attach suitable wet pick-up tools to the hose. (An optional Wand Caddy Kit (pn 56412223) is available from Nilfisk-Advance).
3 Turn the Master Key Switch (33) ON, next press and hold the Vacuum Button (29) until the indicator light turns green. The vacuum motor will run
continuously until the button is pressed again to turn it OFF. 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.

AFTER USE

1 When finished scrubbing, depress the Scrub Off Button (25) twice, this will automatically raise, retract and stop all the machine systems (brush, squeegee,
vacuum & solution). Then drive the machine to a service area for daily maintenance and review of other needed service up keep.
2 To empty the solution tank, remove the Solution Drain Hose (24) from it's storage clamp. Direct the hose to a designated "DISPOSAL SITE" and remove
the plug. Rinse the tank with clean water.
3 To empty the recovery tank, pull the Recovery Tank Drain Hose (21) from it's storage area. Direct the hose to a designated "DISPOSAL SITE" and remove
the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). Rinse the tank with clean water.
4 Remove the brushes or pad holders. Rinse the brushes or pads in warm water and hang up to dry.
5 Remove the squeegee, rinse it with warm water and re-install on mount.
6 Remove the hopper on cylindrical systems and clean thoroughly. Remove from left side of machine by opening skirt and tilting hopper up and away from
housing, then pull out.
