IMPORTANT: If your machine is equipped with the on--board battery charger, make sure that the charger is properly set for your battery type before charging (See USING THE ON--BOARD BATTERY
CHARGER on page 16).
HOW THE MACHINE WORKS
Conventional Scrubbing:
Water and detergent from the solution tank flow to the floor through a manually controlled solution valve. The brush uses the detergent and water solution to scrub the floor clean. As the machine moves forward, the squeegee wipes the dirty solution from the floor into the recovery tank.
Foam Scrubbing (FaST Model):
( FaST -F oam a ctivated S crubbing T echnology)
Unlike conventional scrubbing, the FaST system injects the FaST--PAK concentrate formula with a small amount of water and air onto the floor. The mixture creates a large volume of expanded wet foam for the brush to scrub the floor clean. As the machine moves forward, the foam collapses and the squeegee recovers the dirty solution into the recovery tank leaving the floor clean, dry and slip free.
ec- H2O Scrubbing ( ec- H2O Model):
( ec--H2O --electrically converted water)
Normal water passes through a module where it is oxygenated and charged with an electric current. The electrically converted water changes into a blended acidic and alkaline solution forming a neutral pH cleaner. The converted water attacks the dirt, breaks it into smaller particles, and pulls it off the floor surface allowing the machine to easily scrub away the suspended soil. The converted water then returns to normal water in the recovery tank.
