Installation guidelines:
Maintain 0.02mm/m alignment tolerance during rail mounting.
Use torque-controlled tightening (1.2-1.5Nm for M4 screws).
Apply initial lubrication through grease nipple before operation.
Avoid side-load impacts exceeding 15% of C0.
For vertical installations, use dual blocks or auxiliary support.
