This machine will require maintenance to keep the treadmill running at it’s best, factors such as where the item is stored and how often the machine is used will affect the length of time between the necessary maintenance. It is recommended to perform this maintenance every six weeks.


  1. Balance
  2. Cleaning
  3. Adjusting the running belt
  4. Lubrication



1 x Silicone Oil                                            1 x Allen Key

NOTE: Both of these tools will come with your assembly pack


Try to place your treadmill on a level floor, if this is not possible then you will need to adjust the rubber feet located under the treadmill.

To check if your treadmill is balanced start by:

  1. Placing both of your feet on either side of the running board
  2. Change your weight from right to left

3. If you feel a wobble turn the rubber feet to adjust the level


For your treadmill to work efficiently make sure to keep it clear of dust and debris. Any small parts on the belt can cause damage to the board and possibly the motor. After every workout things such body oils, perspiration, hand lotions and moisturisers can reduce the sensitivity of the pulse sensors. It is recommended to use a dry cloth for cleaning the monitor and handrails, this will prevent any corrosion. For cleaning the belt, set the speed of the treadmill to approximately 2 kph (Kilometres Per Hour) and hold a clean cloth at the end of the belt. Only use water lightly to clean the belt and not any cleaning products as these may damage the treadmill. It is recommended to vacuum or sweep under and around the treadmill to prevent any debris or dust going into the inside of the machine. A treadmill mat can help to avoid this situation from occurring.


One way of checking if the belt is loose is to:

Place your feet on either side of the treadmill

Set the speed between 1-2 kph (Kilometres Per Hour)

Try to stop the belt using your feet whilst holding onto the handrails

If the belt stops this means it is too loose, if not your belt is tight enough

A second way of checking is to:

look at the gap between the running belt and the running board

The gap should be between 5-6 mm

If the gap is smaller then your belt is too loose

To tighten the running belt:

  1. Start by switching off the power to the treadmill
  2. Locate the top bolts at the end of the treadmill

3. Using the allen key turn the bolts quarter by quarter

4. Test the belt after each turn and make sure to reciprocate each turn on either bolt

NOTE: Both of these tools will come with your assembly pack

The way to align the belt is to:

Set the speed of the treadmill between 2-3kph

Using the same bolts as in the previous stage, slowly turn each one

If the belt is aligned to the left, adjust the left bolt clockwise or adjust the right bolt anticlockwise

Visa versa if the belt is aligned to the right

Keep checking the gap between the frames and the belt as you do this, the gap should be between 5-6 mm

Once complete run the treadmill at 6 kph for a few minutes to make sure the belt remains in the center


How often you lubricate the board will vary depending on the amount of use and the conditions of where the treadmill is stored. As this action falls under maintenance, any fault with the treadmill that is caused by the board failing to oiled unfortunately the cost of any parts and labour will not be covered under the warranty as this is not a manufacturing error.

To lubricate the running belt:

  1. Start by disconnecting the treadmill from any power supply

2. Lift up one side of the treadmill belt

3. Run your fingers across the board, if there is oily residue the board is lubricated

4. If not, run the oil in a straight line down the deck

5. Repeat this on the opposite side

6. Switch on the machine and leave it to run between 2-3 minutes at 3-4 kph
