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.

DANGER
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.

Please Note for American use only.

Parts and Service
Please contact Mytee service personnel or a Mytee authorized Service Center using Mytee’s original replacement parts and accessories if repairs need to be performed. When and if calling Mytee for support, please have your Model and Serial Number available for faster assistance.

space provided in this manual to note down both for future reference.

Unpacking the Machine

Machine Operation

2.1 – Powering the T-Rex
Plug the female end of the extension cord into the pigtail on the T-Rex. Next plug the male end of the extension cord into a standard, grounded outlet. The plugs will light up when powered correctly.

2.2 – Installing the Cleaning Head
Lay the T-Rex back onto the handle. Take the cleaning head and place it into the T-Rex housing, lining up the female threaded shaft on the head with the male threaded shaft on the T-Rex. Spin the head clockwise until it stops.

To remove the head, use the included head removal wrench and place it so it hooks onto the spray bars. Then, give it a sharp turn counter-clockwise to break it loose. Spin the head off the rest of the way by hand.

2.3 – Connecting the Hoses

Connect a vacuum hose via 2” Cuff-Lynx™ to the clear plastic elbow. Insert the male end of the Cuff-Lynx™ and turn clockwise until it stops to secure.
Connect the female end of a solution line to the male quick disconnect fitting coming from the handle.

2.4 – Lowering the Handle

Lower the handle to a comfortable height by squeezing the adjustment lever on the left side of the handle and moving the handle down. Release the lever to lock the handle into place.

It is recommended the handle be set to about hip height when the head is flush with the ground for operation.

2.5 – Switching on the T-Rex

Lift up on the handle so the cleaning head is flush with the carpet and the wheels are off the ground. Flip the safety lockout switch forward with your thumb and squeeze the power switch lever on the left side of the handle to start the motor. You can now let go of the safety lockout switch.

.It may be easiest to set the motor speed to the lowest setting using the knob on the front of the handle before switching the machine on.

2.6 – Cleaning with the T-Rex

When operating, the T-Rex will stay in one spot while spinning as long as the head is flush against the carpet. To swing the head to the right, lift the handle up slightly. To swing to the left, lower the handle slightly.

To spray the solution, squeeze the solution lever on the right side of the handle.
For best results, clean using an arc pattern or a circular motion.

2.7 – After Cleaning
After cleaning, switch off the T-Rex by releasing the power switch lever.
Remove any built-up fibers or debris from the cleaning head and wipe down. Store the T-Rex in the included protective head cover to protect the cleaning head from damage.

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

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

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).
