Trackmaster manufactures a line of fitness treadmills as well as several models used in medical testing procedures. Many Trackmaster treadmills are sold under private-label brands, though a few are sold under the Trackmaster name. Over time, you may experience problems with your treadmill ranging from a malfunctioning display unit to a belt that's off-center. Fortunately, many of these problems can be fixed using simple tools and basic troubleshooting techniques.
Step 1
Unplug your Trackmaster treadmill from the wall before performing any troubleshooting or repairs.
Step 2
Lift the base of the treadmill and fold it up against the wall. Use a vacuum with a soft brush attachment to clean dirt and dust from inside the base of the unit. Clean the floor area under and around the treadmill to keep this dust from shortening the life of the motor.
Step 3
Place the base of the treadmill back on the floor. If your device is rattly or feels unstable, check that the treadmill is resting on a level surface. Add a rubber exercise mat under the treadmill to improve stability if needed.
Step 4
Use a screwdriver or Allen wrench to tighten all screws and bolts on your treadmill. Turn these fasteners to the right to tighten them, but avoid over-tightening as this may strip the bolts. Add a bit of lubricant or WD-40 to the fasteners if they are difficult to turn.
Step 5
Look at the base of the your treadmill along the back end to find a pair of belt adjustment screws. These screws are located along the end of the belt, opposite the end with the display unit.
Step 6
Use an Allen wrench to tighten or loosen the belt as needed. Turn both adjustment screws 1/4 turn clockwise to tighten the belt, or 1/4 turn counterclockwise to loosen the belt.
Step 7
Recenter the belt along the tracks. Turn only the right adjustment screw to move the belt to the right, or the left screw to move the belt to the left. Stop when the belt is centered along the track, with equal spacing along both sides.
Step 8
Apply lubricant to the belt if it appears to be sticking or scraping other parts of the treadmill. Choose a lubricant designed especially for treadmills from your local sporting goods store. Squeeze the lubricant along the length of the belt. Place these rows of lubricant along both edges of the belt, a few inches from the edge.
Step 9
Run your treadmill at 2 to 3 miles per hour for five minutes without walking on it to distribute the lubricant. Use a rag to wipe away excess lubricant before using the treadmill.
Step 10
Troubleshoot the treadmill display. Try replacing the batteries, or unplugging the unit from the wall and waiting five minutes before plugging it back in. Check all connectors and plugs into the display and press them firmly in place to ensure they are connected. If you notice any damaged or frayed cables, or if you are unable to fix the display, contact Trackmaster for assistance.
