Repairing and Maintaining Your Treadmill


Once you can walk on the belt at low speed without it stopping or slipping increase the speed to 3 miles per hour. This should be a fast walk. If your unit has side rails hold the rails and try to stop the belt with pressure. IF OK then increase the speed to 5 MPH. Run on the treadmill, if you feel any slipping tighten the bolts another 1/2 turn each. Repeat if necessary.

If the belt is not centered, stand behind the treadmill and run the belt at full speed, if the belt is tracking to the left. Tighten the left bolt or screw 1/2 of a turn, and loosen the right bolt or screw 1/4 turn until the belt is centered. IF the belt is tracking to the right, tighten the right side bolt or screw 1/2 turn and loosen the left bolt or screw 1/4 turn. Repeat as necessary, this should center the walking belt. Always wipe the treadmill down after each use, perspiration is very corrosive. If your treadmill inclines increase the elevation to maximum and vacuum underneath. If it doesn't incline pull it out and vacuum. Most operating problems are usually easily seen, detected and repaired. If the cause of a problem is not obvious, follow a logical process of checking each component in the system.

Repair of Your Treadmill

I t would be impossible for me to list every problem for every manufacturer’s treadmill in this report, but here are some common problems:


  • Walking belt is not centered. See preventive maintenance procedure for centering belt.
  • No power, check that the unit is plugged in to a live outlet, ALWAYS USE CAUTION when dealing with electricity. Try another outlet if you need to.
  • If you know the outlet is live, unplug the unit and check the fuses, you may need to lift the cover for this.
  • IF you have power but the motor does not turn you either have a bad power supply or the motor brushes are worn. Contact the manufacturer for information.
  • If the motor is turning make sure the drive belt is not loose or broken. Tighten or replace as needed.
  • Walking belt moves, but there is a loud grinding noise.
  • Loosen the belt and see if the noise goes away, if it does you may have a bad front roller. Sometimes you can spray the bearing in the roller with a lubricant like WD40 and this will solve the problem, but you may need to replace the roller.
  • If the noise does not go away then the motor bearings are probably bad and you will have to replace the motor.
  • Elevation does not work; unit will not go up or down or is stuck in the elevated mode

Unplug the unit and check the elevation motor fuse, replace if necessary. Check the elevation system for broken chains or cables; make sure something hasn't gotten caught in the gears. If your unit is equipped with limit switches for the up and down limits check them to be sure they are not engaged. These are usually little micro switches located around the elevation gears.
