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.
Please Note for America use only

Preparation

Remove furniture and other items from the area you are going to clean.
Vacuum carpet and upholstery, and remove debris.
Protect cabinets, walls and painted surfaces with drop cloths or plastic.
Inspect power cords for damages.
Remove protective wrapping from wheels.

IMPORTANT: Make sure the felt seal on top of the cleaning head is thoroughly lubricated before using the T-REX™ Jr.
Attach the cleaning head at the base of the T-REX™Jr. First, lean the T-REX™ Jr. back and rest it on the handle. Second, thread the head onto the exposed shaft in a counterclockwise direction.
Attach vacuum and solution hoses to unit.

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™ Jr.’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 property, 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

When machine is transported or stored, apply the head protector.
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.
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.	x
Visually inspect machine for damage to cleaning heads, etc. Repair as necessary.	x
Clean machine with an all purpose cleaner and damp cloth.	x
Remove the in-line solution filter screen and rinse under water to remove debris.	x
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.	x
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.	x
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.		x
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.		x
WARNING: Operating the unit without the gearbox properly lubricated can result in damage.
Lubricate the felt vacuum seal with 30W SAE motor oil.		x
Coat the shaft with WD40 or a similar lubricant.		x
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.

Troubleshooting

Problem:	Possible Causes:	Solutions:
Gear box is making loud grinding noise while running. (When gears are properly working, the motor will run quietly.	Offset gear is dam- aged.	Replace the gear. (Part #H237. See next page.)
Machine power is powering the control board, but unit will not run.	A power cord could be disconnected.	Check all cord con- nections, including the cord plug connections at the motor.
	Activation microswitch (Part #H167) is faulty, or out of adjustment.	Replace activation microswitch
	Speed slide potenti- ometer (Part #E363) is faulty.	Replace speed slide potentiometer
On a new unit: The release lever for adjusting the handle angle seems “stuck”.	Handle plunger gear may stick to the gear rack. This is due to the texture of each mating part caus- ing friction. With use, the textures are smoothed.	Shake the handle, while pulling the release lever. Light application of dry lu- bricant afterward may be helpful. This situ- ation happens rarely, and usually only once or twice, when unit is new.
Cleaning unit head seems to rotate slower than normal.	Felt vacuum seal ring in head 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.
The drive motor seems to be getting overly warm or hot.	Felt vacuum seal ring in head is not properly lubricated.
Perceptible loss of vacuum.	Check that the felt vacuum seal in head is not worn, crushed, or dry.	Replace felt vacuum seal (Part #G014). Lubricate new seal before installation.
Motor is to cycling, as if turning on-and-off rapidly.	Motor carbon brushes are likely worn.	Replace motor carbon brushes immediately (Part #C311B-BMK).
Sparks and/or smoke from motor.
Marked decrease in power of motor.

TIPS

WARNING: Flammable materials or reactive metals can cause an explo-sion or fire.
Do not pick up.

Do not operate the machine over floor moldings. Damage to the molding and the head will occur.
Do not operate the machine on concrete or hardwood floors. The machine is designed for carpet use only. Use on other surfaces will cause damage to the unit.
Do not operate your machine over loose or unraveled carpet seams. The cleaning head may grab the loose piece and cause further damage.

Do not clean over the edge of loose carpet. Extraction heads will catch the carpet edge.
Work away from outlet and power cord to prevent cord damage.
During cleaning of plush carpet, you may notice some loose yarns being thrown from the sides of the extraction head. This is normal.

On carpets that have delaminated (the face has come loose from the backing), this machine may cause further delamination. When in doubt, do not use the unit.
The machine will leave carpet with “swirl marks” from the cleaning pro-cess. These should be brushed out at the end of cleaning with a carpet rake or brush.
To clean heavily soiled areas, repeat cleaning path from different direction. After cleaning, relieve water pressure from tool before disconnecting hose. Squeeze trigger for five seconds after turning main power switch off. Always hook up solution and vacuum hoses to the machine BEFORE turn-ing on pumps or motors.

Solution lines will be difficult, if not impossible to plug in while pump is pressurized.

LUBRICATING VACUUM SEAL ON TOP OF HEAD

Make sure to keep your felt seal (Part # G014) lubricated. To do this, saturate the felt seal thoroughly with Mytee’s lubricant (Part # PH648).

LUBRICATING FELT SEAL

If you have run out of lubricant when it comes time to replace the felt seal, you may use a quality, 30 weight SAE motor oil in its place. Place the new felt seal in a bag along with some oil. Make sure that the entire felt seal is thoroughly lubricated.

MANEUVERING YOUR T-REX™ JR. Your T-REX™ Jr. maneuvers much like a floor machine. Slightly lift handle to move to the right. Press the handle down slightly to move to the left. Tilting your T-REX™ Jr. may result in carpet damage. Remember to always keep T-REX™ Jr. evenly balanced on the surface.

CORRECT CLEANING PATTERNS

To get the best carpet cleaning results, move your T-REX™ Jr. in an arc pattern or circular motion. To remove stubborn stains, try hovering the T-REX™ Jr. over the stain.
