EN OPERATION
HOW THE MACHINE WORKS
Conventional Scrubbing (Standard Model):
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 S crubbing T echnology)
Unlike conventional scrubbing, the FaST system injects the patented 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 wipes the dirty solution into the the recovery tank leaving the floor completely dry and slip free.
The foam scrubbing application (FaST) can increase productivity by 30% by reducing the dump/fill cycle. It will also reduce chemical usage and storage space.
One FaST--PAK can scrub up to 90,000 sq. meters.
NOTE: The FaST model can also be operated as a conventional scrubber. However, it’s important that you follow the instructions in this manual to prevent FaST system failure.
