Verify the inspection is performed before the unit is placed into service.
Confirm the equipment-specific operating instructions and inspection record are available at the point of use.

Compressor and Air Supply System

Verify fluid levels are within the manufacturer-specified range and there are no visible leaks.
Check all visible compressor-related hoses and lines for wear, chafing, bulging, or air leakage.

Inspect the full visible hose length for abrasion, kinks, bulges, delamination, or exposed reinforcement.
Verify all fittings are properly seated, secured, and free of air leaks or missing sealing components.
