2) Loosen the LS cam plate fixing screws (special head screw M1.4 × 1.4) A and B by 90 degrees.
3) Pressing the center of the LS chassis block with the force of 15.0 ± 2.0N•m (153.0 ± 25.0kgf•cm) (as shown by the large arrow mark).
4) While pressing the center of the LS chassis block, and while pulling the LS cam plate fixing screw A (special head screw M1.4 × 1.4)
with the force of 2.5 ± 0.5 N•m (25.5 ± 2.5kgf•cm) (as shown by the small arrow mark), tighten the LS cam plate fixing screw A
(special head screw M1.4 × 1.4).
Tightening torque: 0.1 ± 0.01 N•m (1.02 ± 0.1 kgf•cm)
