Spring carries Atlas Copco part number 3376620053 and is stocked here under AC-3376620053. Springs in a tool fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It shows up in the parts breakdown for the PHB 3-14 Hydraulic Post Hole Borer. 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.
The parts diagram library indexes every breakdown we publish, and the Atlas Copco lineup has the tools these parts go into. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
