Operations How This Machine Works Deluxe Only The Machine is a battery powered, self-propelled Carpet Maintainer and Carpet Extractor intended for commercial use. The function of the chemical injection system is to deliver the appropriate chemical into the solution system to be applied to the carpet. The chemical injection system consists of the "A" chemical tank, "B" chemical tank, chemical selector valve, chemical pump, and the mixing sector.

Operations 5 2 4 3 1 6 7 Drive Controls 1. Key Switch 6. Hour Meter 2. Reverse Switch 7. E-Stop Button (Deluxe) 3. Throttle Switches 4. Speed Control Knob 5.
Operations 1. Key Switch Controls the power for machine functions. To turn the machine power on, rotate key clockwise. To turn the machine off, rotate key counterclockwise. 2. Reverse Button Controls the direction of travel of the vehicle. To travel in reverse, press the button and press either of the throttle switches. To travel forward, release the button are press either of the throttle switches. 3. Throttle Switches Propel the vehicle with the speed control knob setting selected.
Operations 2 3 1 Scrub Controls 1. Solution Pump Switch 2. Solution Pump Indicator 3.
Operations 1. Solution Pump Switch Controls power to the spray pump. If the throttle is in neutral, or reverse control button is in reverse position, the flow is automatically interrupted. This feature prevents application of solution without scrubbing it into carpet. 2. Solution Pump Indicator Light The solution pump indicator light is illuminated green when the pump is on. 3.
Operations Scrub Deck Rotary Switch (Deluxe) Raises and lowers the scrub deck, and turns the scrub brush motors on and off, and controls the solution solenoids. For interim/pre-spray "A" mode, rotate the function knob to the "A" position. The "A" chemical will be drawn from its tank and delivered to the solution system. The scrub deck will lower and the scrub motor will turn on and the interim/ pre-spray solenoid will open and spray will flow through the jets.
Operations Machine Operation Emergency Stop Procedures Pre-Run Machine Inspection Do a pre-run inspection to find possible problems that could cause poor performance or lost time from breakdown. Follow the same procedure each time to avoid missing steps. NOTE: See maintenance section for pre-run machine inspection checklist items. Starting Machine NOTE: Perform pre-run machine check before operating machine.
Operations Filling Solution Tank Normal Scrubbing FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key. 1. Turn the machine power off. 2. Remove the front cover and the solution fill lid. 3. Fill the solution tank with clean water. (See the Technical Specifications chart for exact capacity). The water must not be hotter than 140° F (60°C) to prevent damage to the tank. 4. Replace the solution fill lid and front cover. Deluxe 1.
Operations To Begin Scrubbing To Stop Scrubbing When operating the machine around people, pay close attention for unexpected movement. Use extra caution around children. 1. While scrubbing turn off the pump switch to stop spraying solution. Continue to scrub and recover the solution for an additional pass. 2. Allow the throttle switches to return to neutral. 3. Rotate the selector switch to the accessory position so that the vacuum motor continues to run and evacuate the system.
Operations Emptying And Cleaning Chemical Tanks And System (Deluxe) 1. Turn off machine and remove front cover. 2. Park the machine next to a floor drain. The tanks are located at the front of the machine. 3. Remove the cap and straw from each chemical bottle and install the closed caps. SOLUTION DRAIN HOSE 4. Remove the tanks by lifting off the solution fill tower. 5. The chemical can remain in the tank or be disposed of properly. Remove one cap at a time and properly dispose of chemical.

Maintenance Service Schedule Before Each Work Period Maintenance Check water level of batteries after charging; add distilled water if necessary. Check brushes for proper installation. Check for securely attached drain hose, plug and cap. Check that solution fill lid seals tightly Visually check for damaged or worn tires. Check all throttle, direction and speed controls for proper operation. Observe spray pattern and clean jets if necessary. Prime chemical system for 30 seconds for each chemical.
Maintenance 1. Battery Connector 5. "Y" Tube 2. Battery Connector 6a. Recovery Hose - Basic 3. Batteries 6b. Recovery Hose - Deluxe 4.
Maintenance Batteries (Wet Cell Only) The batteries provide the power to operate the machine. The batteries require regular maintenance to keep them operating at peak efficiency. The machine batteries will hold their charge for long periods of time, but they can only be charged a certain number of times. To get the greatest life from the batteries, charge them when their charge level reaches 25% of a full charge. Use a hydrometer to check the charge level.
Maintenance NOTE: Do not take readings immediately after adding distilled water, if the water and acid are not thoroughly mixed, the reading may not be accurate. Check the hydrometer readings against this chart. SPECIFIC GRAVITY @ 80° F (27°C) BATTERY CONDITION 1.265 100% CHARGED 1.225 75% CHARGED 1.190 50% CHARGED 1.155 25% CHARGED 1.120 DISCHARGED NOTE: If the readings are taken when the battery electrolyte is any temperature other than 80°F (27°C), the reading must be temperature corrected.
Maintenance 5. Check the electrolyte level in each battery cell. Before charging, add just enough distilled water to cover the plates. After charging is complete, add just enough distilled water to bring up the level to the indicator ring. If the water level is too high before charging, normal expansion rate of the electrolyte may cause an overflow resulting in a loss of battery acid balance and damage the machine. 6. Replace the battery caps, and leave them in place while charging. 6.
