Page 14: Know Your Machine
KNOW YOUR MACHINE CONTROL MODULE DESCRIPTION The ConvertaMAX™ 20/26 / BA 550/650 scrubbers have an electronic module that controls the activation of the scrub brush motors for scrubbing and removal of the brushes/pads and the low voltage cutout function. For normal scrubbing the brush motor(s) will activate only if the brushes are down and the Drive Paddle (5) (throttle) is in the forward or reverse position. -
Page 15: Solution System
SOLUTION SYSTEM FUNCTIONAL OVERVIEW The 20-gallon (76 l.) capacity solution tank uses two fill openings one located in the front and another in the rear, which offers ease of filling. Plumbed onto the tank outlet is a serviceable solution filter, to keep debris from entering the solenoid valve. Also fitted to the tank is flexible hose used to indicate the solution level and to drain the tank for system maintenance. -

Page 31: Recovery System
RECOVERY SYSTEM FUNCTIONAL OVERVIEW Vacuum / Recovery System General Dirt and water are lifted off the floor into the recovery tank by airflow, created by a 3-Stage 24V vacuum motor. The wastewater and air enter the vacuum system at the squeegee tool, through small openings (notches) located in the front squeegee blade. The small openings are the entrance points for the water and air, and help speed up the airflow producing the suction to lift the wastewater off of the floor. -
