SOLE started by manufacturing treadmills for hotels and expanded to manufacturing for home use. According to their mission statement, SOLE's goal is to provide excellent customer service. They provide a full lifetime warranty for treadmill motors and a three-to-five-year warranty for parts. However, there are several things you can do to repair your own treadmill. SOLE's treadmills consist of several basic parts: the belt on the rollers, the frame base, the uprights, the handles and the console.

Treadmill Belt Tightening
Tighten the rear roller slightly using the Allen wrench.
Find the rear holes in the back of the treadmill. Use the Allen wrench to turn both bolts a quarter of a turn. Test the tension.
Adjust the belt a quarter of a turn until the belt does not slip. Tighten both sides evenly.
Tread-Belt Tracking Adjustment
Turn the treadmill on to 3 miles per hour.
Find the left side bolt at the rear of the treadmill. If the belt is too close to the left, then you will turn the bolt clockwise (to the right). If the belt is too close to the right, you will turn the bolt counter clockwise (to the left).
Turn the bolt a quarter of a turn at a time -- using the Allen wrench -- until the belt is centered on the treadmill.
Calibrating the Treadmill
Remove the safety key. Hold down the "Start" and "Fast" buttons and replace the safety key. Keep holding "Start" and "Fast" until "factory settings" appears on the screen. Press "Enter."
Adjust wheel-size diameter to 2.30. Press "Enter." Adjust minimum speed to 0.5, maximum speed to 12 and maximum elevation to 15. Turn the grade return on. Step off the treadmill and press "Start."
Remove the motor cover hood with your Phillips-head screwdriver by loosening the four screws. Locate the speed sensor beside the front roller pulley.
Loosen the screw holding the speed sensor. Align the sensor with the magnet on the front of the pulley. Tighten the screw on the sensor again and replace the motor cover. Run the calibration again.
Lubricating the Treadmill
Clean between the belt and deck using a non-fraying, clean cloth. Push the cloth half way between the motor belt and the end of the treadmill until you can hold it on both sides of the belt. Drag it back and forth over the length of the belt one or two times.
Turn the power off and unplug the cord. Measure 18 inches from the end of the motor cover, using the tape measure.
Squeeze an S shape of lubricant under the belt perpendicular to the motor cover around 6 inches from the side of the treadmill. Repeat on the other side.
Plug the treadmill in and turn it on. Walk on the treadmill at a moderate pace for five minutes until the lubricant spreads out under the belt.
