Steps to replace the roller
Step 1: Remove the screws that fix the rear tail base, remove the rear cover, then remove the screws that fix the rear roller, and take off the rear roller.
Step 2: Open the motor cover and remove the screws that fix the motor cover, tighten the screws that tighten the balance between the small belt and the top motor, and then remove the screws that fix the motor base to the frame. Then remove the front roller.
Step 3: Replace the front and rear rollers with new ones. First screw the hexagon socket screws that fix the front roller to the appropriate position, and then put the rear roller in the corresponding position to fix the screws.
Step 4: Adjust the small belt in a straight line, and tighten the motor screw that fixes the small belt until the small belt is turned by hand to 45 degrees. Then tighten the motor balancing screws to balance the top of the motor.
Step 5: Put on the motor cover and tighten the screws that fix the motor cover.
Step 6: Turn on the treadmill at a speed of about 3km/h. If the running belt is offset to the left, turn on the treadmill at a speed of about 3km/h. Adjust the hexagon socket screw in the left rear tail cover to turn clockwise (twist each time half turn) Until the running belt is centered. Or adjust the inner hexagonal screw in the rear cover on the right side and turn it counterclockwise (twist each time half turn) until the running belt is centered. If the running belt is shifted to the right, turn on the treadmill at a speed of about 3km/h, and adjust the hexagon socket screw in the right rear tail cover to turn clockwise (each time half-turn) until the running belt is centered. Or adjust the inner hexagonal screw in the rear cover on the left and turn it counterclockwise (twist each time half a turn) until the running belt is centered.
