Calibration procedure:
1) Remove the safety key
2) Press and hold down the Start and Fast (speed up) buttons with one hand and replace the safety key with the other. Continue to hold the Start and Fast key until the window displays “Factory settings”, then press the enter key.
3) You will now be able to set the display to show Metric or English settings. To do this press the up or down key to show which you want, then press enter.
4) Make sure the wheel size diameter is 2.75 then press enter
5) Adjust the minimum speed (if needed) to 0.5 and then press enter
6) Adjust the maximum speed (if needed) to 12.0 and then press enter
7) Adjust the maximum elevation (if needed) to 15 and then press enter
8) Press start to begin calibration. The process is automatic; the speed will start up without warning so do not stand on the belt.

Belt / Deck Lubrication
 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 catastrophic failure of these expensive components. Failure to lubricate the deck at regular intervals may void the warranty. The deck comes pre-lubricated and subsequent lubrication should be performed every 180 hours of use, or every three months, whichever comes first. The console has a built in lubrication reminder indicator that lights every 180 hours of use. 

To lubricate the deck with the tube of lubricant supplied it will be necessary to loosen the walking belt. Using the 6 mm allen wrench supplied, loosen the two rear roller adjustment bolts -- located in the rear end caps – enough to get your hand under the belt (5 –10 turns). Make sure to loosen both bolts the same amount of turns and also remember how many turns, because when finished you will need to tighten the bolts back to the point they were before. 

Once the belt is loose, wipe the deck with a clean lint free cloth to remove any dirt. Apply the whole tube of lubricant onto the deck surface about 18 inches from the motor cover. Squeeze out the contents of the tube across the deck (parallel to the motor cover) in about a one foot line, like toothpaste on a toothbrush. The one foot line should be in the middle of the deck at approximately equal distance from both side edges of the belt. You want the lubricant to be applied about the spot that your feet would hit the belt as you are walking. This should be about 18 inches from the motor cover, but you may want to walk on the treadmill before loosening the belt to note where your feet land on the belt. If you mostly run on the treadmill the spot where your feet land may be different from walking. Once the lubricant is applied, tighten the rear roller bolts the same amount of turns as when you loosened them. Run the treadmill at about 6 mph without walking on it for about a minute or two to make sure the belt stays in the middle of the deck. If the belt tracks to one side then follow the belt tracking instructions to remedy. Now the deck is lubricated and you should walk, not run, on the treadmill immediately for at least 5 minutes to ensure the lubricant is evenly distributed. If you purchase a Lube-N-Walk kit, follow the instructions that come with it to apply the lubrication.

General Maintenance
Belt and Bed
Your treadmill uses a very high-effi cient low-friction bed. Performance is maximized when the bed 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 a month to extend belt and bed 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. Allow to dry before using.
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. Once a year, you should remove the black motor hood and vacuum out dirt that may accumulate. UNPLUG POWER CORD BEFORE THIS TASK.
Belt Adjustments
Treadbelt Tension Adjustment - Belt tension is not critical for most users. It is very important for joggers and runners in order to provide a smooth, steady running surface. Adjustment must be made from the right side of the rear roller in order to adjust tension with the 1/4 allen wrench provided in the parts package. The adjustment bolt is located at the end of the right side rail as noted in diagram below.

Tighten the rear roller only enough to prevent slippage at the front roller. Turn the treadbelt tension adjusting bolt in increments of 1/4 turn and inspect for proper tension. When an adjustment is made to the belt tension, you must also make a tracking adjustment to compensate for the change in belt tension. This is accomplished by turning both the tension and tracking allen bolts an equal amount. This adjustment should be made by turning both bolts clockwise by no more than a 1/4 turn at a time.
DO NOT OVERTIGHTEN - Overtightening will cause belt damage and premature bearing failure.

Treadmill belt Tracking Adjustment
The performance of your treadmill is dependent on the frame running on a reasonably level surface. If the frame is not level, the front and back roller cannot run parallel, and constant belt adjustment may be necessary. The treadmill is designed to keep the treadbelt reasonably centered while in use. It is normal for some belts to vary near a side while the belt is running with no one on it. After a few minutes of use, the treadbelt should have a tendency to center itself. If, during use, the belt continues to move toward one side, adjustments are necessary.
To Set Treadmill belt Tracking
A 1/4 allen wrench is provided to adjust the rear roller. Make tracking adjustments from the left side only. Set belt speed at approximately 2 to 3 mph. A small adjustment can make a dramatic difference. Turn the bolt only a 1/4 turn 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. The belt may require periodic tracking adjustment depending on use and walking/running characteristics. Some users will affect tracking differently. Expect to make adjustments as required to center the treadbelt. Adjustments will become less of a maintenance concern as the belt is used. Proper belt tracking is an owner responsibility common with all treadmills. CAUTION - KEEP HANDS CLEAR OF MOVING REAR PULLEY.

Speed Sensor Alignment 
To adjust the speed sensor.
1. Remove the plastic motor cover. There are either 4 or 5 screws holding the cover in place depending on the model.
2. Locate the speed sensor between the front roller pulley and the frame of the treadmill. It is a small plastic piece approx 1 1/4” long and 1/4” in diameter with a black wire coming from the back of it leading to the electronic
board in the motor compartment .
3. Locate the magnets mounted in the face of the pulley. (approx. 3/8” in diameter)
4. The end of the sensor should be positioned approximately 1/8” from the magnet at the closest point.
5. Follow the wire from the sensor to the control board. Make sure the connection is pressed firmly down on the board.
