Page 2 RX Express III Preparation and Precautions TO PREPARE... Carefully remove the unit from its shipping container and inspect for damage.

Remove the solid shipping plug from the top of the gearbox and replace it with the vented plug provided.
RX Express III Page 3 GROUNDING INSTRUCTIONS (cont.) : The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the grounding blade to a live terminal. Your terminal is designed to be used on less than 150 volts and has plugs resembling the one shown in Figure A. A grounding adapter is available locally for connecting plugs to 2-prong receptacles. The green (or green and yellow) right lug extending from the adapter must be connected to a properly grounded outlet.
Page 4 RX Express III Operation CONTROLS There are three switches installed in the dash box located on the main handle assembly, one each for the vacuum pump, cleaning head, and solution pump. The handle also contains a trigger for activating the solution valve. MANEUVERABILITY The ease of handling the RX-Express is a direct result of the rotary extractor head. Its natural cleaning motion provides the “drive” for the unit.
RX Express III Page 5 PUMP PRIMING MODE Connect the auxiliary pump line supplied with the unit to the male coupler at the rear of the machine. Disconnect the vacuum hose intake from the left side of the recovery tank and place the end of the auxiliary line up into the opening. Using your hand to create a seal around the line, turn on the vacuum and solution pumps until you see water coming out of the hose.
Page 6 RX Express III Cleaning Instructions 1. Fill the solution tank with hot water. The higher the temperature of the water, the better the cleaning action of the machine and the chemicals used. However, do not exceed a water temperature of 160 F. When accessible, fill the machine directly from a utility sink. When this is not an option, a clean, five gallon bucket will suffice. Add the necessary chemicals. Now you are ready.

Page 10 RX Express III Maintenance MONTHLY... 1. Check the oil level in the gearbox on a monthly basis. This is a permanent lubricated gearbox. You do not need to change the oil. However, maintain ing the proper oil level is important. To check the oil level, remove the vent plug and look into the gearbox. Turn the “star” until you can see the inspection hole in the gear. With the unit sitting flat, the oil level should be up to, but not over, the middle of the gear.
RX Express III Page 11 WEEKLY... 1. Clean the Recovery Tank thoroughly by removing the tank and rinsing with clear water. ! CAUTION DAILY... 1. 2. Clean off any accumulated debris on the gearbox shaft or inside the threaded portion of the hub. An accumulation of debris around the gearbox shaft, if not removed, may damage the gearbox oil seal resulting in loss of oil in the gearbox. If the gearbox is operated without oil, severe damage may occur. (This requires removing the cleaning head.
Page 12 RX Express III Coat the motor shaft with lubricant before reinstalling the cleaning head. Locate the head onto the shaft, making sure the threads are aligned properly, and rotate the head counterclockwise.
RX Express III Page 13 Repair Guide IMPORTANT: Make sure the machine is unplugged before the removal of any electrical parts. Removal of Cleaning Head: 1. First, unscrew the head in the same direction it turns during operation (or clockwise when looking from the underside). 2. Once you have loosened the assembly, spin if off with your hands. If the cleaning head is difficult to remove, you may use a ¾” socket wrench on the exposed center nut.
