• Verify pin dimensions match carrier machine specifications
• Ensure quick coupler (if used) is rated for attachment weight
• Connect hydraulic lines if applicable (tilt, rotate, grapple)

• Daily: Visual inspection, check for loose pins, hydraulic leaks
• Weekly: Grease all pivot points, check wear plate thickness
