How to assemble a treadmill

Most home treadmills arrive with the deck and motor already built; you raise the uprights, fit the console and connect one cable. The heavy lifting and the cable are where things go wrong, so take your time with both.

Tools needed

  • Allen keys (supplied)
  • Spanner (supplied)
  • Cross-head screwdriver
  • Spirit level

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Base with deck, belt and motor
  • Left and right uprights
  • Console and handlebars
  • Console cable and safety key
  • Bolts, washers and covers

Step by step

  1. Step 1: Unpack where the treadmill will stand. Leave the clearance the manual specifies behind the deck and at the sides.

  2. Step 2: With your helper, lift the base out of the box by its frame, not by the motor cover or the belt.

  3. Step 3: Stand the uprights in their brackets and start all bolts by hand. Feed the console cable up through the right upright without pinching it.

  4. Step 4: Fit the console and handlebars to the tops of the uprights, connect the console cable plug firmly, and tuck the cable in so no bolt can crush it.

  5. Step 5: Tighten all bolts evenly, then fit the side covers.

  6. Step 6: Check the treadmill is level and adjust the feet if needed.

  7. Step 7: Check the belt is centred and has the tension the manual describes. Plug the treadmill into a wall socket (not an extension lead) and test at a low speed with the safety key clipped to your clothing.

Common mistakes

  • Trapping the console cable between the upright and its bracket, which crushes it.
  • Using an extension lead or multi-plug, which can overheat.
  • Running it straight away at high speed without checking the belt tracking.

Safety notes

  • Always clip the safety key to your clothing when running.
  • Keep children and pets away; unplug and remove the key after use.
  • Leave clear space behind the treadmill as the manual specifies.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
