Release the latch and unfold the treadmill. Lift the right foot rail up and off.

Turn the right side roller adjustment Allen screw to release the walking belt tension. Lift the rear roller up and out of the mounting bracket.
Remove the front roller adjustment nut and screw. Lift the front roller up and out of its mounting bracket.
Fold the treadmill up and engage the latch. Remove the front and rear corner screws that fasten the right side of the walking board to the frame.
Release the latch and unfold the treadmill. Lift and hold the right side of the walking platform up and slide the walking belt off the walking board and belt rollers.

Lift the right side of the walking board up and slide the new walking belt over the walking board and belt rollers. Fold the treadmill up and engage the latch.
Reinstall the right front and right rear mounting screws to fasten the platform to the frame. Release the latch and unfold the treadmill.
Position the front roller in the mounting bracket and reinstall the mounting screw and nut in their original position. Position the rear roller adjustment screw with the washers to outer side of the rear roller-mounting bracket.

Reinstall the right side foot rail and mounting screws.

Plug the treadmill into the electrical outlet.
Do not walk on the treadmill while checking and adjusting the belt tracking.

If the belt is not tracking in the center, remove the key and unplug the power cord.
Use the Allen wrench supplied with the treadmill and adjust the rear rollers as needed to center the walking belt. If the belt is tracking to the left of center, turn the left roller adjustment screw clockwise 1/2 of a turn.

After adjustment, restore power and recheck the tracking.
Repeat until the walking belt is tracking in the center.

Plug the treadmill into the electrical outlet and insert the safety key.

Attach the safety key cord to your clothing and walk on the belt for a few minutes to evenly spread the silicone lubricant across the walking board.

Treadmills are a great way to stay fit and active at home. However, like all mechanical devices, they need regular maintenance. Proper maintenance can prolong the lifespan of your treadmill walking belt. Keep the belt clean and free from debris by wiping it down after each use. Regular lubrication can also reduce friction and prevent premature wear. Check your treadmill's user manual for recommended lubricants and application instructions.
