Monthly Care and Service
1. Clean the treadmill of dust and dirt that might accumulate under and behind the treadmill. Vacuum small rubber particles from the soles of running shoes that accumulate alongside the belt and behind the machine.
2. Inspect the autowaxer for sufficient wax in the wax channel.
a. Lay treadmill on its side.
b. Pull back the treadbelt (on the bottom of the treadmill) to expose the wax channel.
c. The wax channel should be at least ¼” thick at its thinnest point.
d. Feel along the full length of the wax channel for consistent thickness.
e. Call authorized service technician to replace wax channel if it is less than ¼” thick at any point.
NOTE: To prevent damage to the treadbelt, do not allow the treadmill to run without sufficient wax in the wax channel.
Once every three (3) months we recommend that the motor cover be removed and the motor area vacuumed thoroughly to remove dust and particles. Only authorized service personnel should perform this procedure as only authorized service technicians are allowed access to the area under the motor hood. A thorough visual inspection should be performed at this time as well. Have the technician check for tight wire harness connections, damaged motor or power wires, tight motor and tensioner bolts, tight
 ground screw connections and wire tie downs, properly attached incline motor cotter pin and clevis pin, and tight motor controller and interface screws.
Expert service and maintenance at a modest cost are available through your factory trained authorized TRUE dealer. He maintains a stock of repair parts and has the technical knowledge to meet your service needs.
Incline and Speed Calibration
The Incline and Speed Calibration mode is used to troubleshoot and calibrate the treadmill. Calibration will cause the treadmill to speed up to 15 mph and incline up to 15%.
CAUTION: Keep area under the treadmill free from obstructions because the deck returns to 0% grade when the safety key is replaced. Failure to do so could cause personal injury or damage to the machine.
1. Hold (up/down) while placing the SAFETY KEY onto the Keyboard to enter the Calibration Mode.
The following messages will repeat themselves one at a time:
NOTE: While in this mode, (up/down) and (plus/minus) can be used to change the treadmill incline and speed. The SPEED Window will display actual speed.
2. Press (Start) to start calibration. The treadmill will lower to zero incline and then start increasing incline to
15% and speed to 15 mph.
3. When the calibration is complete:
The following message will display in the Message Center:
