Start with the suspension drawing
Reverse-air bags in a common design are suspended under tension and change shape during cleaning. Check the upper attachment, spring or hanger design and lower connection shown on the approved drawing. Record the bag length and the specified installed setting before work begins.
Use one method at every position
In the approved isolated state, use the equipment-specific measurement point and method. Note whether a reading represents spring travel, installed dimension or direct force. Compare like readings across positions and record exceptions with the bag and hanger identification.
Investigate a mismatch before resetting it
If a setting is out of range, verify the supplied bag length, attachment position and condition of the suspension hardware. Confirm the correct adjustment with the manufacturer. Keep the as-left setting and any scheduled recheck with the work record.
FAQ: Can I use the same setting for every model?
Use the approved value and measurement method for the specific suspension and bag design. Readings from another design may represent a different spring, reference length or attachment geometry.
