PICK-UP Tool Maintenance

12 ENGLISH

Check the pick-up tools daily. Remove any built-up string, hair or carpet fibers.

SPRAY NOZZLE MAINTENANCE

Remove the spray nozzles once a week. Soak the nozzles overnight in a vinegar and water solution to remove chemical deposits.

LUBRICATING THE MACHINE

Once a month (or every 30 hours), lubricate all pivot points on the pick-up tool assembly. For best results, use a spray silicone lubricant.

Once a month, pump grease into the grease fittings on the caster wheels until it seeps out around the bearing. Wipe off the excess grease to avoid staining carpet.

CLEANING THE VACUUM MOTOR FILTERS

Clean the vacuum motor filters daily with compressed air. For extremely dirty filters, wash with warm, soapy water and rinse thoroughly with clean water. Allow the filters to dry completely before re-installing in the machine. MAINTENANCE NOTE: Keep a second set of filters on hand to use while first set is drying.

ADJUSTING THE BRUSH HEIGHT

Simply turn the Brush Height Adjustment Knob (19) clockwise to raise and counter-clockwise to lower the brush deck. NOTE: The Brush Pressure Indicator (8) should read 8-15 amps when properly adjusted.

POWER BRUSH MAINTENANCE

Check the brush daily. Remove any built-up string, hair or carpet fibers. Check the bristle length. Have a service technician change the brush when the brush bristles are worn to 1/2 inch (12.7 mm).

REMOVING THE BRUSH
