Trigger Valve Guide is the Atlas Copco service part carried under part number 3378512012. It is part of the operator control on the drill. Because it is handled every cycle of every shift, wear here is felt as a vague or sticky trigger long before the machine stops.
You will find it on the diagram for the MHC5 Hydraulic Core Drill.
