Xterra -TR6.8:Engineering mode and calibration 

If you want to set the Speed and Distance to Metric or if there is a problem with the speed and you would like to perform the calibration procedure, use the Engineering Mode. To enter Engineering Mode press, and hold for 5 seconds, the Start and Speed UP keys while installing the safety key. All the segments will light then the message window will display
software versions and tell you to press Enter.
* The display will ask for grade return. This will reset the incline to zero, when set to ON, when you stop a program.
* The message window will now be showing the setting for English (miles) or Metric (Kilometers) Use the UP/DOWN keys to select and press Enter
* The message window will ask to adjust the wheel size for calibration. Enter 63.
* The display will show a number for the lowest speed setting (for miles the number should be 0.5). Adjust the low speed setting with the UP/DOWN keys and press Enter.
* The display will show a number for the top speed setting (for Miles it should be 12.0).
* The display will ask for top incline setting, enter 15.
* Press Start to begin calibration. This is an automatic process, the belt will move and change speeds without warning. Be Careful. When calibration is done, the console will return to the startup screen

Maintenance Tips

Belt and Deck - Your treadmill uses a very high-efficient low-friction deck. Performance is maximized when the deck is kept as clean as possible. Use a soft, damp cloth or paper towel to wipe the edge of the belt and the area between the belt edge and frame. Also reach as far as practical directly under the belt edge. This should be done once every other month to extend belt and deck life. Use water only - no cleaners or abrasives. A mild soap and water solution along with a nylon scrub brush will clean the top of the textured belt.
Belt Dust - This occurs during normal break-in or until the belt stabilizes. Wiping excess off with a damp cloth will minimize buildup.
General Cleaning - Dirt, dust, and pet hair can block air inlets and accumulate on the running belt. On a monthly basis: vacuum underneath your treadmill to prevent buildup. Every other month, you should remove the black motor hood and carefully vacuum out dirt that may accumulate. UNPLUG POWER CORD BEFORE THIS TASK. There is a maintenance schedule/chart included under the Table of Contents for convenient record keeping.

Running Belt Adjustments

Tread-belt Tension Adjustment - Belt tension is not critical for most users. It is very important though for joggers and runners in order to provide a smooth, steady running surface. Adjustment must be made from the rear roller with the 6mm Allen wrench provided in the parts package. The adjustment bolts are located at the end of the step rails as shown in the diagram below. Tighten the rear roller only enough to prevent slippage at the front roller. Turn the tread-belt tension adjusting bolts 1/4 turn each and inspect for proper tension by walking on the belt and making sure it is not slipping or hesitating with each step. When an adjustment is made to the belt tension, you must be sure to turn the bolts on both sides evenly or the belt could start tracking to one side instead of running in the middle of the deck.

DO NOT OVERTIGHTEN – Over tightening will cause belt damage and premature bearing failure. If you tighten the belt a lot and it still slips, the problem could actually be the drive belt - located under the motor cover - that connects the motor to the front roller. If that belt is loose it feels similar to the walking belt being loose. Tightening the motor belt should be done by a trained service person.

Running belt Tracking Adjustment

The treadmill is designed so that the tread-belt remains reasonably centered while in use. It is normal for some belts to drift near one side while in use, depending on a user’s gait and if they favor one leg. But if during use the belt continues to move toward one side, adjustments are necessary.
SETTING TREAD-BELT TRACKING
An 6mm Allen wrench is provided for this adjustment. Make tracking adjustments on the left side bolt. Set belt speed at 3 mph. Be aware that a small adjustment can make a dramatic difference which may not be apparent right away. If the belt is too close to the left side, then turn the bolt only a 1/4 turn to the right (clockwise) and wait a few minutes for the belt to adjust itself. Continue to make 1/4 turns until the belt stabilizes in the center of the running deck.

If the belt is too close to the right side, turn the bolt counter-clockwise. The belt may require periodic tracking adjustment depending on use and walking/running characteristics. Some users may affect tracking differently. Expect to make adjustments as required to center the tread-belt. Adjustments will become less of a maintenance concern as the belt is used. Proper belt tracking is an owner responsibility common with all treadmills.
Running belt and Deck Lubrication Procedure

First, you want to clean between the belt and deck to remove any debris that may be trapped. Use a clean, non-fraying rag, t-shirt, or light towel. Halfway between the end of the treadmill and motor cover, shove the garment under the belt until you can grasp it on both sides of the belt. Drag the garment the length of the entire belt 1-2 times. Remove the garment.

Keeping the deck lubricated at the recommended intervals ensures the longest life possible for your treadmill. If the lubricant dries out, the friction between the belt and deck rises and places undue stress on the drive motor, drive belt and electronic motor control board, which could result in failure of these components.

The belt & deck come pre-lubricated and subsequent lubrication should be performed every 90 hours of use or if you notice that the deck is dry. It is recommended that you reach between the belt and deck to verify there is lubrication present, every other month. If you check and there isn’t any lubrication present, follow the procedure below even though the “Lube” indicator isn’t lit on the console. Otherwise, lubricate when the console’s lubrication reminder lights after 90 hours of use. Use the following procedure to apply the silicone lubricant:

1. Turn the power switch off and unplug the power cord from the wall outlet
2. Measure 18” from the edge of the motor cover; kneel down and reach under the belt approximately 4- 6” from one edge. Squirt a line of lubricant about 1/8” wide x 15” long in an “S” pattern perpendicular to the motor cover.
3. Repeat the process on the opposite side.
4. Plug the electrical cord back into the outlet and turn the power switch on.
5. Walk on the belt at a moderate speed for five minutes to evenly distribute the silicone lube.
6. Note: If the “Lube” message appears on the console, perform the following procedure to reset the message:
1. To enter the Engineering Mode Menu press and hold down the Start, Stop and Enter keys, then at the same time insert the safety key. Keep holding the keys down until the Display displays Engineering Mode Menu. Press the Enter key to access.
2. Press the Speed UP key (or Speed DOWN key to go backwards) until “Functions” appears; press Enter
3. Press the Speed UP key until “Reset Lube” message appears; press Enter
4. Press Stop to exit Engineering mode and resume use of your treadmill.
