Replacing the Timing Belt

1. Use a hex wrench to loosen the screws securing the timing belt and remove the old belt.

2. Installing the new timing belt:

1）Place the timing belt along the direction of the red arrow, with the toothed side facing down.

2）Secure with flat washer screws: place a flat washer on the M5x10 screw, press the timing belt with the washer, and tighten the screw.

T-nut method: slide the T-nut onto one end of the belt, rotate the T-nut with a hex wrench, then screw in the M5x6 screw to secure one end of the belt.

3）Pull the belt taut by hand, then fix the other end using the same method as above.

4）Repeat the same steps to install the other belt on the left frame.

Note: When securing the timing belt, avoid over-tightening the screw and washer on the belt to prevent damage.
