Mounting advice:
Ensure parallel alignment within 0.05mm/m using precision level.
Apply Loctite 243 to mounting screws (torque ≤1.2Nm).
Avoid side-load impacts during installation.
Maintenance note:
Clean rail surfaces weekly with lint-free cloth soaked in
ISO VG10-15 oil. Never use acetone-based cleaners.
