919.154010 hose connection
by: Anonymous

If you are asking about the 919.154010, there should be a discharge coupling threaded onto the nipple going into the air regulator.

It is possible that this has been removed, or was not there in the first place.

Simply thread a coupler into the outflow from the regulator, and plug the air line connector into that.

Air purging out of the check valve
by: Bill

This compressor has a tank check valve and unloader combination. Essentially, the unloader vents air from over the piston when the compressor stops.

If air is bleeding out the bleed hole all the time, that typically means that the check valve is leaking.

Please see the pages on Unloader Valves, Check Valves and the Troubleshooting page that links to things you can check when your air compressor runs but does not build pressure.
