Introduction

Dear Customer:
Congratulations on the purchase of your new T-Rex Rotary Extractor. As technology continues to develop you can work confidently knowing that both Mytee and its employees are equally dedicated to developing with the industry and its advances.

Like any other piece of machinery or technology, the T-Rex also requires proper maintenance and care to keep the product working over extended use. Neglecting your machine, abusing it, or not operating it properly can void its warranty and prevent the machine from performing to the quality and standard you’d expect out of the Mytee line.

If you have any warranty concerns or questions, please review this manual thoroughly or do not hesitate to contact your distributor. If there are questions regarding maintenance, replacement, or ordering parts please contact an authorized Mytee Service Center. To see an updated list please visit our website at https://www.mytee.com/support/find-distributors/.
Before using your Mytee product, please read this manual thoroughly.
Sincerely, Mytee Customer Care Dept.

Important Safety Information

Please read and understand this manual completely before operating this machine.

Grounding Instructions
This machine must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electrical shock. This machine 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 codes and ordinances. Do not remove the ground pin; if missing, replace the plug before use.

MYTEE T-Rex Series T-REX-115 Total Rotary Extractor Carpet Cleaner User Manual  & troubleshooting 3DANGER
Improper installation of the equipment-grounding the 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 the plug or the machine’s cord, instead have a proper outlet installed by a qualified 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 a proper outlet is not available, follow the illustrations in Figures 2 & 3 to install a temporary-grounding plug. This temporary workaround 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.

Machine Maintenance

In order to keep the T-Rex running smoothly and reduce the risk of damage to the machine and subsequent downtime, Mytee recommends following the maintenance schedule below:

Maintenance Item Daily

Weekly

Inspect cords and hoses for breaks or tears. Replace any damaged items.  

X

Visually inspect machines for damage to cleaning heads, etc. Repair as necessary.  

X

Clean the machine with an all-purpose cleaner and damp cloth. X
Check the spray jets for even spray. X
Make sure the felt vacuum seal is well lubricated. X
Wash the cleaning head and housing thoroughly, being sure not to wet the motor assembly. Clean any lint buildup from the star and vacuum heads. X
Clean off any debris that is on the shaft of the motor or the hub of the cleaning head. 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.
X
Coat the shaft with WD40 or a similar lubricant.

WARNING: When reinstalling the cleaning head, make sure that it spins freely. If it begins to require pressure, unscrew it and clean the threads. Dirt or grit can block the threads, and if you continue to tighten, may lock the star on the motor shaft.

3.1 – Lubricating the Felt Vacuum Seal

MYTEE T-Rex Series T-REX-115 Total Rotary Extractor Carpet Cleaner User Manual  & troubleshooting 16

It is important to keep the felt vacuum seal lubricated thoroughly so as to reduce friction and ensure a tight vacuum seal. Use the included SuperLube® (part number PH648) to saturate the felt seal thoroughly as often as possible.

Troubleshooting

The motor fan is spinning but the cleaning head is not.
Possible Cause Solution
Pinion gear has broken. Replace the pinion gear. (Part #H129)
Machine power is powering the control board, but the unit will not run.
Possible Causes Solutions
A power cord could be disconnected. Check all cord connections, including the cord plug connections at the motor.
The activation microswitch (Part #H167) is faulty, or out of adjustment. Replace activation microswitch.
Speed potentiometer (Part #E363A) is faulty. Replace the speed potentiometer.
The release lever for adjusting the handle angle sticks.

Possible Causes

Solutions

Handle plunger gear may stick to the gear rack. This is due to the texture of each mating part causing friction. With use, the textures are smoothed. Shake the handle, while pulling the release lever. A light application of dry lubricant afterward may be helpful. This situation

happens rarely, and usually only once or twice, when the unit is new

The cleaning unit head seems to rotate slower than normal or the motor is getting abnormally hot.
Possible Cause Solution
The felt vacuum seal ring is not properly lubricated. Saturate felt vacuum seal with included SuperLube® (Part #PH648) or 30 wt SAE motor oil. Apply oil until near saturated, but not dripping.
Perceptible loss of vacuum.
Possible Causes Solutions
Check that the felt vacuum Replace felt vacuum
seal in the head is not worn, seal (Part #G014).
crushed, or dry. Lubricate new seal before installation.
Motor smokes, sparks, cycles power or has a sub- substantial decrease in power.
Possible Causes Solutions
Motor carbon brushes are likely worn. Replace motor carbon brushes immediately (Part #C311-BMK).
