THE SCRUBBING SYSTEM - HOW IT WORKS

There are two scrubbing systems available for the CR 1500 machine, the non-recycling or standard scrubbing system and the recycling or ESP scrubbing system.

THE NON-RECYCLING OR STANDARD SCRUBBING SYSTEM - HOW IT WORKS

During the scrubbing process (shown in Figure 13), detergent solution water from the solution tank is fed to the solution line. There it is fed to the ﬂ oor where three disc scrubbing brushes work to dislodge soil.

After scrubbing, the dirty solution is vacuumed from the ﬂ oor and discharged into the containment chamber in the forward portion of the recovery tank, where a system of bafﬂ es helps to clarify the solution. Sensors in each tank will indicate by lights on the control panel when the water in the solution tank is too low or when the water in the recovery tank is too high.

SCRUBBING SYSTEM OPERATING INSTRUCTIONS THE RECOVERY OR ESP SCRUBBING SYSTEM - HOW IT WORKS

During the scrubbing process (shown in Figure 15), ﬁ ltered water from the solution tank is fed to the solution line, where it combines with detergent from the metering pump. This mixture is then fed to the ﬂ oor where three disc scrubbing brushes work to dislodge soil.

After scrubbing, the dirty solution is vacuumed from the ﬂ oor and discharged into the containment chamber in the forward portion of the recovery tank, where a system of bafﬂ es helps to clarify the solution on its way to the pumping chamber in the rear of the recovery tank. At intervals, a system of sensors activates the recycling pump, which sends ﬁ ltered solution from the pumping chamber on its way to the solution tank. Here, it is ready to be mixed with fresh, metered detergent and repeat the cycle.

DUST CONTROL OPERATING INSTRUCTIONS THE VARIABLE DUMP SWEEPING AND DUST CONTROL SYSTEMS - HOW THEY WORK

Variable Dump CR 1500 machines are equipped with a sweeping and dust control system. Figure 16 shows the highest position for the variable dump.

AE Hopper Door Lever AF Hopper Lift Lever

FIGURE 16

FIGURE 17

The debris from sweeping is thrown into the hopper (Figure 17). The bafﬂ e system that is built into the variable dump debris hopper is designed to minimize dust in the air while the machine is sweeping. The impeller vacuum fan pulls the lighter dust up and through a bafﬂ e system. The Pre- Clean Flap separates the heavier dust particles to an area below the ﬁ lters. The dust ﬁ lters capture the lighter dust particles. This allows the dust ﬁ lters to remain cleaner and need less shaking to remove dust. When the dust ﬁ lters become clogged the ﬁ lter shaker switch should be pushed to start the dust shaker cycle. This will extend the life of the ﬁ lters.

OPERATING INSTRUCTIONS HELPFUL HINTS FOR CLEANING OPERATION

SIDE AISLES

MAIN AISLE

SIDE AISLES

FIGURE 18

WARNING

Do not turn the steering wheel sharply when the machine is in motion. The sweeper is very

responsive to movement of the steering wheel. Do not make sudden turns.

Scrub in straight paths. Do not bump posts. Do not scrape the sides of the machine.

When the machine is in motion, do not push the directional/speed control pedal all the way forward. This is the

same as starting in “High” and will put a strain on the motor and drive system.

1. Plan your sweeping and scrubbing in advance. Try to arrange long runs with minimum stopping and starting. Sweep debris from narrow aisles out into main aisle ahead of time. Do an entire ﬂ oor, or section at one time.

2. Pick up oversize debris before sweeping.

3. Allow a few inches overlap of sweep and scrub paths. This will eliminate leaving dirty patches.

4. Don’t turn steering wheel too sharply when machine is in motion. The machine is very responsive to movement of the steering wheel - so avoid sudden turns.

5. Try to follow as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine.

6. When placing the machine in motion, avoid slamming the directional control pedal all the way forward quickly. This is equivalent to starting out in “HIGH” and puts needless strain on the engine and drive system.

7. Always allow the machine to warm up before operating in cold temperatures.

8. Periodically turn sweeping (main) broom end for end to prevent the bristles from “setting” in one direction.

NOTE

Replace sweeping broom when bristles are worn to 3-inch (8-cm.) length. Replace disc brushes when bristles

are reduced to 1/2 inch (1.3 cm) in length. Replace squeegee blades when all usable edges have become

rounded with wear, impairing the wiping action.
