Treadmill Maintenance & Repairs

Maintenance Of Your Treadmill

Maintenance of your treadmill is very important to maximise the longevity and quality of the machine.  Simple tasks performed at regular intervals will allow you to obtain the maximum benefit from your machine.




  • Remove the excessive accumulation of dust and dirt with a clean soft cloth and a non-abrasive liquid cleaner. When wiping down the display board and heart rate grips DO NOT spray cleaner directly onto surfaces and don’t use under the running belt.
  • When cleaning under the running belt use a soft, dry cloth. Slide the cloth between the running belt and running deck you may need to use a ruler or similar tool, until cloth emerges at other side. Then pull the cloth from the head roller down to the rear roller. Do not clean the running belt whilst machine is on.
  • Inspect your machine including the running belt for alignment and tension. The belt does not need to be tightened every day.
  • To ensure the power cord does not interfere with the elevation screws make sure it is positioned away and not under the treadmill where it could be damaged or pinched.


  • Hoover the floor surrounding the treadmill including underneath. Take care when vacuuming and be sure not to damage the power cord.
  • Perform and inspect the following:
  • The display and handrails for stability while securing, tightening bolts where necessary. The console for wear of buttons, lights and anything irregular. Surface of the running deck, ensure there is no irregular wear patches, cracks or wood fragments exposed. A replacement of the running belt should be replaced if it is glazed or torn.


WARNING: To prevent personal injury, always turn the treadmill off and unplug the power cord before performing maintenance inside the motor compartment.

  • Remove the shroud covering the motor compartment. Carefully vacuum around the motor and ventilation holes. Be careful not to bump or damage any of the parts within the compartment the shroud protects.


  • Check and wipe down elevation screws with a clean dry cloth and coat them with silicon lubricant spray (such as silicon) to prevent rust accumulation and noise.



  • Remove the motor shroud and operate the treadmill at a slow speed of 1 – 2 mph (2 – 3kph).
  • Step onto the treadmill, carefully observe the front roller and try to slow it down by pressing your body weight down on the running belt using the handrails as support.
  • If you note that only the running belt slows down, the belt needs to be tightened by turning the rear roller adjustments (see running belt adjustment for more details).
  • Replace the motor shroud.
  • If both the running belt and front roller slow again the drive belt will need tightening.
  • See below ‘Slipping drive belt’


  • Put the treadmill to an incline of 5% this will provide clearance underneath.
  • Now first turn the treadmill switch to the OFF position then unplug the machine.
  • Carefully remove the motor shroud.
  • Loosen the four motor bolts with a 1/2’’ socket wrench.
  • Adjust the tension bolt in the middle of the motor bracket with the same wrench in ¼ clockwise rotations, this will stretch the drive belt (please do-not over tighten this will cause stress on motor/roller bearings)
  • To check proper tension use thumb and forefinger, grip the middle of the belt twisting should only reach 3 degrees either side.
  • Tighten the four bolts previously loosened the replace the motor shroud.
  • Plug the treadmill back into the wall socket switch to ON position and test for slipping as described above in ‘slipping running belt’ .
  • Repeat this step if necessary.


Maintaining the running belt is very important and a few simple maintenance steps can help reduce maintenance costs and unnecessary downtime.

Tensioning the Belt

  • WARNING!!  Over-tightening of the belt may reduce its longevity and also damage other parts of your treadmill.
  • Tensioning the belt is a completely normal process, which many home users neglect.
  • Whilst using your treadmill if you feel that the running belt it sticking to the deck then it is likely a tightening issue.
  • All you have to do is to tension both rear roller allen bolts by 1/4 turn.


  • Maintaining the roller is a very important part of keeping your treadmill in peak operational order. Dirt can build up on the rollers which can cause rough feelings, noise and unwanted belt tracking.
  • To clean the roller uses a plastic scrapper or an old credit card to remove any build up of debris.
  • Rear roller debris build up steps…
  • Make sure the treadmill is OFF and unplugged.
  • To loosen the running belt turn the right and left roller adjustment located at the rear of the machine counter-clockwise with a ¼’’ Allen wrench.
  • Note the number of times the bolt is turned.
  • Now remove excess derby build up with a plastic implement ie an old credit card (DO NOT use a metal or abrasive objects).
  • Repeat the noted rotations of the bolts to tighten the running belt.
  • Turn the treadmill back on and test belt alignment and adjust position by further rotation in ¼ turns of the rear roller adjustment bolts.



  • Use anything metal or sandpaper as you will damage the coating of the roller.
