Heading up to Alaska for some work and it reminded me of last time. Wheelovator next door was not taking full load, noticed in log service mechanic had taken the pressure down to 650 from 1150. Question is where in the bloody heck is the pressure relief adjustment for this POS. No prints or manuals, old route mechanic doesn't work for us and wouldn't answer his phone when I tried to call him.

Any help appreciated, not going for this, but I may pop over to see if it's working properly now.
