* When securing each end of the Y slider belt, make sure it is not slanted and is positioned at the
approximate center of the B belt stay.
* Secure the ends of the Y slider belt with a tightening torque of 8 kg-cm. This is to prevent
malfunction of the circuit boards at low temperatures and to ensure electrical contact between the Y
slider and the Y slider belt.
* When mounting belt stays B, make sure the M3 x L6 screws are not inserted at an angle.
* As shown in Fig.4-22, ensure that the tension spring fits properly on the screw head on the spring
adjustment plate.
* Do not forget to secure the spring adjustment board.
