SPEED SCRUB RIDER - Caliber Equipment

OPERATION FOAM SCRUBBING SYSTEM (FaST MODEL) HOW THE MACHINE WORKS The scrub components of the machine are a solution tank, scrub brushes or pads, a squeegee, a vacuum fan, and a recovery tank. The buttons on the control panel control the machine scrubbing functions. The One Step Scrub button turns the preset scrub functions on and off. The FaST button (option) enables the FaST (Foam Scrubbing Technology) system. The ec--H2O button (option) enables the ec--H2O (electrically converted water) system. The vacuum fan / squeegee button turns the vacuum fan on/off and raises and lowers the squeegee. The brush pressure buttons control the scrub brush pressure, and the solution buttons control the solution flow. Unlike conventional scrubbing, the optional FaST (Foam Scrubbing Technology) system operates by injecting the FaST--PAK concentrate agent into the system with a small amount of water and air. This mixture creates a large volume of expanded wet foam. The expanded foam mixture is then dispersed onto the floor while the machine is scrubbing. When the squeegee picks up the mixture, the patented foaming agent has collapsed and is recovered into the recovery tank. The steering wheel controls the path of the machine travel. The directional switch controls the forward or reverse direction of the machine. The propel pedal controls the speed of the machine. The brake pedal slows and stops the machine. There are two different types of scrub heads available, cylindrical and disk. Both scrub heads are available in two different widths. The Disk scrub head is available in 650 mm (26 in) wide and 800 mm (32 in) wide. The Cylindrical scrub head is available in 700 mm (28 in) wide and 800 mm (32 in) wide. NOTE: The amount and type of soilage play an important role in determining the type of brushes or pads to use. For specific recommendations, see the BRUSH INFORMATION section of this manual or contact a Tennant representative. CONVENTIONAL SCRUBBING Water and detergent from the solution tank flow to the floor through a solution valve. The brushes use the detergent and water solution to scrub the floor clean. As the machine propels forward, the squeegee wipes the dirty solution from the floor. The suction created by the vacuum fan then draws the dirty solution from the squeegee into the recovery tank. The Safe Scrubbing Alternativer The FaST system can be used with all double scrubbing and heavy duty scrubbing applications. Using the FaST system improves safety and can increase productivity by 30% by reducing your dump/fill cycle. It will also reduce chemical usage and storage space. One FaST--PAK of concentrated agent can scrub up to 90,000 m2 (1 million square feet). NOTE: Do not use the FaST system with conventional cleaning detergents in the solution tank. Drain, rinse and refill the solution tank with clear cool water before operating the FaST system. Conventional cleaning detergents may cause failure to the FaST system. 6 SpeedScrub Rider 331140 (02--09) Home Find. Go To.

OPERATION ec- H2O SCRUBBING (ec- H2O Model) The ec--H2O (electrically converted water) system operates by producing electrically converted water for cleaning. 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. The ec--H2O system can be used with all double scrubbing applications. NOTE: Do not enable the ec--H2O system with conventional cleaning detergents in the solution tank. Drain, raise and refill the solution tank with clear cool water only before operating the ec--H2O system. Conventional cleaning detergents/ restorers may cause failure to the ec--H2O solution system. NOTE: Storage or transporting machines equipped with ec--H2O in freezing temperatures requires special procedures. Follow the freeze protection procedure located in the STORAGE INFORMATION section. BRUSH INFORMATION For best results, use the correct brush type for the cleaning application. The following are recommended brush applications.
