Tip for removing hot-melt glue on the cable terminal :
Apply a small amount of alcohol to the hot-melt glue, then carefully remove it with pliers.

Step 1 – Preliminary Check

• Confirm whether the incline adjustment buttons and running belt can operate normally.

Step 2 – If the Incline Buttons Work, but the Belt Does Not Start

Perform incline calibration:

1. Remove the safety key.

2. Press and hold the Incline Down button and Speed 8 button simultaneously for 3–5 seconds until a long beep sounds.

3. Re-insert the safety key.

4. The treadmill motor will automatically perform a complete incline calibration cycle.

5. Check if the error is cleared.

   • If cleared → treadmill should function normally.

   • If not cleared → proceed to Step 2.

Step 3 – If Incline Buttons Do Not Work and Belt Cannot Start

1. Unplug the treadmill and ensure it is completely powered off for at least 5 minutes.

2. Open the motor cover (refer to the attached video).

3. Locate the terminal indicated by the green arrow in the diagram.

4. Carefully reconnect the terminal:

   • The terminal may have glue applied during production.

   • Clean the terminal with a cloth slightly dampened with alcohol to soften the glue before reconnecting.

5. After reconnecting the terminal, power on the treadmill and perform the incline calibration as described in Step 1.

6. Check if the treadmill operates normally.

   • If still abnormal → consider control board failure or linear actuator (incline motor) failure.
