  • Page 17: Operating Instructions

    Solution and Vacuum Hose Connections Your RX-20 is equipped with a 440 male quick connect for the solution hose connection and a 2” O.D. vacuum hose inlet (see Figure 4-1). The vacuum inlet requires a 2” I.D.

  • Page 18: Operation

    RX-20 Electrical Cord Connection The 50 ft electrical cord on your RX-20 (120 V/60 Hz configuration) is a permanently attached, three-prong grounded line requiring a three-prong, 15 Amp receptacle. A three-prong to two-prong adapter may be used if its ground wire is properly attached to a grounded terminal.

    Maneuvering Your RX-20 Your RX-20 maneuvers like a rotary floor machine. To move the RX-20 to the right, lift the handle slightly (see Figure 4-3). The more you lift or lower the handle, the faster the RX-20 will move. Figure 4-3. Lift or Lower Handle to Maneuver; Illustration to the Right...

  • Page 20: Figure 4-4. Correct Cleaning Patterns

    To familiarize yourself with your RX-20, practice on an open area. Depress both the solution trigger and motor trigger and move the RX-20 slowly in a 3 to 5-ft arc, as shown in Figure 4-4. Figure 4-4. Correct Cleaning Patterns After you have become familiar with the speed and movement of the machine, practice making it hover in one spot.

  • Page 21: Cleaning Information

    3. DO NOT operate your RX-20 over loose or unraveled carpet seams. The cleaning head may catch and cause further damage. 4. DO NOT operate your RX-20 on concrete floors. It will develop sharp edges on the extraction heads that will damage carpet fibers.

  • Page 22: Special Information

    With an RX-20, loose yarns form balls and are kicked aside as the cleaning heads revolve. This is normal when aggressive cleaning or even normal vacuuming takes place, as evidenced by a number of dead, loose yarns in the vacuum cleaner bag.

  • Page 23: Machine Maintenance

    Good care and regular maintenance of your RX-20 will result in a long, dependable life for the unit. Keep in mind that your RX-20 will be in full view of your customer. An RX-20 that is dirty and unkempt in appearance can cause your business or professional image to suffer.

  • Page 24: Figure 6-2. Check Jet Spray For Even Flow

    RX-20 Check the spray on the jets for even flow. An uneven spray will cause improper flow of the cleaning solution (see Figure 6-2). Do NOT spray the high pressure solution in your face or eyes. Bodily injury can result.

  • Page 25: Figure 6-5. Clean Off Debris From Gear Box Shaft

    14. Coat the shaft with TKX All-Purpose Lube Gear Box Shaft ® (HydraMaster P/N 000-087-006) or a similar lubricant. Re-install the vacuum head assembly onto the shaft by rotating it counter-clockwise (Figure 6-7). An accumulation of debris in the gear box, if not removed, may damage the gear box oil seal.

  • Page 26: Periodic Maintenance

    To check the oil level, remove the vent plug and look into the gear box. Turn the star until you can see the inspection hole in the gear. When the RX-20 is sitting flat on a table or the floor, the oil level should be up to, but not above, the middle of the gear. If oil needs to be added, use a quality 80-90 weight gear oil.

  • Page 27: Transport And/Or Storage

    FREEZE WARNING AND PROTECTION Your RX-20 can suffer damage from freezing, as can any equipment that functions with the use of water. Care must be taken to protect this machine from freezing just as you do your other equipment.

  • Page 59: Repair And Replacement

    9 - Repair and Replacement FELT VACUUM SEAL The felt vacuum seal plays an important part in the optimum performance of your RX-20. If it is worn or unlubricated, it will not form a proper seal. Lack of a proper seal will impair the vacuuming capabilities of the unit and therefore leave behind more water in the carpet than is desirable.

  • Page 60: High Pressure Valve Assembly

    RX-20 HIGH PRESSURE VALVE ASSEMBLY In the event that the valve assembly needs to be replaced, follow this procedure: Remove the 440 male quick connect with a wrench. Remove the five hex head screws in the back plate on the handle and lift the back plate off.
