Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
It is called out in the parts diagram for the 131 Backfill Tamper. The tool itself is the APT 131 Pneumatic Backfill Tamper. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
