Operating the Vacuum

• Replace the vacuum head and latch it.
• Connect the vacuum hose and accessory.

Maintenance and Storage

Always unplug the machine before performing maintenance.

• After each use: Drain and rinse the recovery tank, clean the float shut-off, and check the filter bag.
• Cleaning: Clean the outside of the machine with a mild cleaner and wipe squeegee blades with a cloth (do not use fingers).
• Monthly: Lubricate wheels, casters, and axles with water-resistant lubricant.
