the compressor that i have has been sitting up for a few years, is there any precautions i should take before running
Bill answers...Howdy Grady:
It's good to check and/or change the oil, for sure.
Make sure the tank drain is closed before you start it. I hope that it was left open?
Let it come up to high pressure cutout and shut off. Listen for leaks, particularly if bleeding out the pressure switch, which would indicate a stuck or failed check valve into the tank.
You might even pull the PRV ring to bleed of air, then push it shut again. This should free it up to operate properly if need be.
I would suggest you visit the Speedaire page (click Speedaire link from the Nav Bar) and follow the guides to ask the Speedaire people where you are what's their recommendation for a compressor lube oil.
Failing that, visit your local compressor store and buy their recommended brand.
Careful you don't overfill when you change the oil.
Cheers,
Bill
