CMX-20 3 - Assembly Instructions To prepare your CMX-20 for use, follow these instructions: 1. Remove the machine from the packaging. Inspect the machine carefully for any damage that may have occurred during shipping. 2. Remove the solid shipping plug from the top of the gear box (see Figure 3-1). 3. Check the gear box lubricant level (see page 6-4 of this Owner’s Manual). 4. Insert the vented plug (provided) into the gear box in place of the solid shipping plug. The solid shipping plug may be discarded.
CMX-20 Assembly Instructions: 3-2
CMX-20 4 - Operating Instructions Preparation 1 Operating instructions presented in this section apply to both the 120 V and 230 V versions of the CMX-20. However, photos and illustrations show only the 120 V version due to space limitations. Handle Adjustment Pull or push on the adjustment lever to adjust the height of the handles (see Figure 4-1). Several adjustments may be needed before a desirable operating position is found. 2 3 Figure 4-1.
CMX-20 Electrical Cord Connection The 50 ft electrical cord on your CMX-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. Do not, under any circumstances, remove the ground prong from your CMX-20 power cord. Serious injury or death may result.
CMX-20 2. To fully engage the motor as you are cleaning, you also need to hold down the momentary switch, or button, at the same time you as you squeeze the motor trigger (see Figure 4-2). The momentary switch is an integrated safety feature on the CMX‑20 which cuts power to the machine if the operator’s hands leave the machine for any reason. 3. On the left-hand side, squeeze the solution trigger to control the high pressure solution spray (see Figure 4-2).
CMX-20 2. To move forward and backward, position the handle so that the unit remains stationary, then push forward or pull back. To familiarize yourself with your CMX-20, practice on an open area. Depress both the solution trigger and motor trigger and move the CMX-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.
CMX-20 5 - Cleaning Information Cleaning Patterns For regular carpet cleaning use an overlapping arc pattern three times over the same area (two passes with solution and one pass for drying). When cleaning carpets, first clean in circular pattern, then use the overlapping arc pattern to dry the area. Dirtiest areas may require two or more cleaning passes. Using either pattern shown in Figure 4-4, you should develop a comfortable rhythm.
CMX-20 Special Information When you clean some plush carpets, you may notice a “pilling” effect. (Pilling occurs when fluffy particles appear on carpet surfaces; it is caused by fibers that loosen because of a weak twist or snags.) With a CMX‑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.
CMX-20 6 - Machine Maintenance Good care and regular maintenance of your CMX‑20 will result in a long, dependable life for the unit. Keep in mind that your CMX‑20 will be in full view of your customer. An CMX‑20 that is dirty and unkempt in appearance can cause your business or professional image to suffer. You are offering your customer the latest in cleaning technology. Therefore, it is important that your company image reflect your desire to give your customer the best.
CMX-20 7. 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. Figure 6-2. Check Jet Spray for Even Flow 8. 9. 10. 11. Figure 6-3. Loosen Cleaning Head Assembly Loosen the cleaning head (star assembly). It unscrews in the same direction it turns during operation (or clockwise when looking at it from the underside) - see Figure 6-3.
CMX-20 12. 13. 14. Clean off any debris that may have accumulated on the gear box shaft or the inside threaded bore of the hub (see Figure 6-5). Lubricate the felt vacuum seal on top of the hub with a quality, 30 weight SAE motor oil. Also, put a few drops into the hub threads (see Figure 6-6). Figure 6-5. Clean Off Debris from Gear Box Shaft Coat the shaft with TKX® All-Purpose Lube or a similar lubricant. Re-install the vacuum head assembly onto the shaft by rotating it counter-clockwise (Figure 6-7).
CMX-20 Periodic Maintenance Check the oil level in the gear box on a monthly basis. This is a permanently lubricated gear box. You do not need to change the oil. However, maintaining the proper oil level is important. 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 CMX‑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.
CMX-20 Transport and/or Storage Whenever your CMX‑20 is transported or stored, U. S. Products recommends that you remove the star assembly (cleaning head). The machine will then sit flat on the floor and remain more stable, especially during transport. Freeze Warning and Protection Your CMX‑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.

CMX-20 9 - Repair and Replacement Felt Vacuum Seal The felt vacuum seal plays an important part in the optimum performance of your CMX‑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. To replace the vacuum seal: Fluffy, Usable Side 1. First, remove the vacuum head assembly as previously described. Compressed, 2.
CMX-20 High Pressure Valve Assembly In the event that the valve assembly needs to be replaced, follow this procedure: 1. 2. 3. 4. 5. 6. 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. Disconnect the stainless steel hose from the bottom of the valve assembly (see Figure 9-2). Remove the bolt holding the trigger (see Figure 9-2). Remove the two bolts holding the valve assembly in the handle (see Figure 9-2).
CMX-20 10 - Troubleshooting 1.0 Low Vacuum Flow at the Cleaning Heads 1.1 Hub not sealing properly. Replace felt seal with a lubricated one. 1.2 Restricted air flow. Remove hoses from the vacuum shoe and skid assembly, and clear them of debris. 1.3 Low vacuum flow from power. Refer to Troubleshooting section of source equipment manual. 2.0 Low Water Flow at Cleaning Heads (indicated by irregular Water Temperature) 2.1 Restricted jets. Remove jets and clear them of debris. 2.2 Clogged water strainer.
