Installation guidelines:
Use M10×1.25 mounting bolts (grade 8.8 or higher) with 35-45 N·m torque.
Maintain 0.5-1mm clearance between rod end and load during alignment.
Lubricate with ISO VG32 hydraulic oil during initial installation.
Critical notes:
Never exceed 1.0 MPa pressure with full stroke operation.
Requires minimum 5μm filtration for abrasive environments.
Allow 15-minute warm-up period for sub-zero temperature startups.
