SPRAY NOZZLE MAINTENANCE
Remove the Maintenance Spray Nozzle (C) once a week. See Figure 7. Soak the nozzle overnight in vinegar to remove chemical deposits.
SOLUTION SCREEN MAINTENANCE
Once a week (or more often if necessary), clean the Solution Screen (13). Drain the solution and recovery tanks. Lift the recovery tank from the
machine and set it off to the side. Reach inside the solution tank and unthread the solution fi lter to remove.
POWER CORD MAINTENANCE
Once a week (or more often if necessary), check the power cord for cracked or damaged insulation, exposed wires in the cord or plug, and damaged
or missing ground pin. Repair or replace damaged cord or plug immediately.
ADJUSTING THE BRUSH PRESSURE
Simply turn the Brush Pressure Adjustment Knob (19) clockwise to increase brush pressure and counter-clockwise to decrease the brush pressure.
POWER BRUSH MAINTENANCE
Check the brush daily. Remove any built-up string, hair or carpet fi bers. When the machine is not in use it should be placed in the storage position.
This will prevent the brush from taking a set which will increase the brush life and maintain the performance of the brush.
REMOVING THE BRUSH
CAUTION!
Turn the power switch off (O) and unplug the machine, before changing the brushes.
1 Empty both the recovery and solution tanks. Lift the recovery tank from the machine and set it off to the side.
2 Place the Handle Assembly (19) into the storage position and tip the machine over onto its back.
3 See Figure 7. Rotate the brush until the Drive Lug (D) is in a position where the fi ns on the drive lug are parallel to the fl oor.
4 Grab the brush at the end with the Brush Retainer Clip (E) and pull straight out.
5 Install a new brush at the drive lug end fi rst then push in the other brush end in until it snaps into the retainer clip.
