Sincerely, Mytee Customer Care Dept. Grounding Instructions This machine must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electrical shock. This ma- chine is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed in accordance with all local code and ordinances. Do not remove ground pin; if missing, replace plug before use. Improper installation of the equipment-grounding conductor can result in a risk of electric shock. Be sure to check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. If the plug will not fit in the outlet do not modify either the plug nor the machine’s cord, instead have a proper outlet installed by a quali- fied technician. This machine is for use on a nominal 120-volt circuit and with a grounding plug similar to the one in Figure 1 below. If a proper outlet is not available, follow the illustrations of Figure 2 & 3 to install a temporary-grounding plug. This temporary work-around should be used only until a proper outlet (Figure 1) can be installed by a qualified electrician. When and if this type of adapter is employed, screw the adapter’s extended tab into place with a metal screw. However, grounding adapters are not approved for use in Canada. Again, be sure to check the grounding pin for damages and replace if necessary. The Green, or Green-Yellow, wire in the cord is the grounding wire. When replacing a plug, this wire must be attached to only the grounding pin. DO NOT use extension cords.

Protect cabinets, walls and painted surfaces with drop cloths or plastic. 4. Inspect power cords for damages. 5. Remove protective wrapping from wheels. 6. IMPORTANT: Make sure the felt seal on top of the cleaning head is thoroughly lubricated before using the T-REX™. 7. Attach the cleaning head at the base of the T-REX™. First, lean the T-REX™ back and rest it on the handle. Second, thread the head onto the exposed shaft in a counterclockwise direction. 8. Attach vacuum and solution hoses to unit. 9. Start extractor per operating instructions for unit. Operating Instructions Step 1 – Adjust the handle. To do so, pull back on handle adjustment lever and move the handle up or down to desired operating position. Most users find that they have better control and less fatigue if the handle is in a low position, just around the hip line. Step 2 – Controlling the motor and spray. There are triggers located on both sides of the handle. The trigger on the left controls the solution flow. Activating this trigger will lay down spray through the jets on the star. The pressure of the spray is determined by the type of pump you have hooked up, either on your portable extractor or truckmount. The trigger on the right hand side controls the motor. To activate the motor, you must first push down the safety lockout, and then pull on the trigger. PLEASE NOTE: Be sure that you have good control of the unit when you activate the motor, as it will move quickly when started. The airflow of the unit is controlled by the vacuum source you have hooked into the machine. The air flows constantly during operation. Step 3 – Maneuvering the unit. The T-REX’s™ movement is controlled by moving the handle up or down (similar to a floor machine). To move the machine to the right, lift the handle slightly. To move to the left, lower the handle slightly. The more you lift or lower the handle, the faster the machine will move. CAUTION – Do not tilt the machine on its side during use! Doing so may result in the ejection of your glides, damage to the star, damage to prop- erty, and/or injury. To move the machine forward or backward, position the machine so the head is “hovering” over one spot, and then push or pull forward or back. CAUTION – Do not operate the machine on dry carpets. The friction caused by the head movement may cause fiber damage to the carpet. After Use 1. When machine is transported or stored, apply the head protector. 2. Blow all air out of unit prior to storing with compressed air. Storing the machine with fluid in the lines can result in serious damage if the unit freezes. 3. Store machine in a dry area in the upright position ATTENTION: Do not expose to rain. Store indoors. ATTENTION: If storing machine in freezing temperatures, be sure that machine and solution system are completely drained and dry. Maintenance Schedule Maintenance item Daily Once a week Inspect cords and hoses for breaks or tears. Replace any damaged items. Visually inspect machine for damage to cleaning heads, etc. Repair as necessary. Clean machine with an all purpose cleaner and damp cloth. Remove the in-line solution filter screen and rinse under water to remove debris. Check the spray jets for even spray. If uneven, the jet may be clogged and need cleaning. If clogged, remove spray tips and soak them in a recommended liquid neutralizer for up to six hours. To remove spray tip, twist spray tip body counter- clockwise. Do not use pointed objects to unplug tips, damage will occur. Check felt vacuum seal daily before use. Make sure that seal is lubricated to near saturation with included SuperLube® or 30 wt SAE motor oil. New units and seals do NOT come pre-lubricated. Remove the cleaning head. It unscrews in a clockwise direction when looking at the underside of the machine. Once you have loosened it, the star should turn freely in your hands. Wash the cleaning head and shroud thoroughly, being sure not to wet the motor assembly. Clean any lint buildup from the star and vacuum heads. Clean off any debris that is on the shaft of the motor or the hub of the star. If not cleaned regularly, debris here can damage the oil seal on the gearbox, and result in loss of oil. WARNING: Operating the unit without the gearbox properly lubricated can result in damage. Lubricate the felt vacuum seal with 30W SAE motor oil. Coat the shaft with WD40 or a similar lubricant. WARNING: When reinstalling the vacuum star, make sure that it spins freely. If it begins to require pressure, unscrew it and clean threads. Dirt or grit can block the threads, and if you continue to tighten, may lock the star on the motor shaft. x x x x x x x x x x GENERAL INFORMATION

TS-TREX-09/02/15 • PAGE # 1 General Troubleshooting Problem: Possible Causes: Solutions: Motor fan is spinning but cleaning head is not. Pinion gear has broken. Replace the pinion gear. (Part # H129. See next page.) IMPORTANT: Do not plug the motor into power directly. Serious damage to the motor will result. The machine should only be powered through the lighted pigtail coming off the handle. TECHNICAL SUPPORT T-REX™ TOTAL ROTARY EXTRACTOR TS-TREX-09/02/15 • PAGE # 2 Step 1: Remove the four bolts holding the transmission and motor together. Step 2: Pull the motor off the transmission. You can use a rubber mallet to loosen the seal if necessary (Figure A). Step 3: Use a Phillips head screwdriver to unscrew the 6 screws on the transmission cap (Figure B). Remove the transmission cap. Step 4: Remove the broken pinion gear. Step 5: Install the new pinion gear (Part # H129) by inserting the gear side into the space beside the large transmission gear. Use the existing grease inside the transmission to lube the pinion gear (Figure C). Twist the pinion gear to make sure the gears are aligned. You should see the large gear spin a little (Figure D). Step 6: Make sure the wave washer is centered on the bearing for the large gear (Figure E). Line up the pins on the transmission casing with the holes on the transmission cap and tap the cap into place (Figure F). The transmission should be on a surface that allows the threaded shaft on the bottom to hang free so that it doesn’t push back up against the cap as you’re trying to tap the cap back on (Figure G). Step 7: Replace the screws with a Phillips screwdriver. The longer screw goes in the hole in the motor cavity. Step 8: Twist the pinion gear by hand to make sure it is aligned properly. You will see the bearing for the main gear spin slightly. Step 9: Match the locking key on the motor shaft to the key slot on the transmission and slide the motor back in place (Figure H). Line up the bolt holes and make sure the power cord is coming out the back.
