Just realized the compressor I bought didn't come with the manual. Saw the "warning" sticker on the plug and now I need to know how to break this thing in.

Any Craftsman owners out there remember how to do this?

TIA

The following is from the owner's manual for my Sears Craftsman 3 HP 12 gallon oil-less compressor (model 919.153030 or 919.153130).

Seems to me it might be better to just open the drain valve while running the compressor during break-in, instead of adjusting the regulator. Note that your regulator may not turn the same direction as mine.

Have fun!

Break-In Procedure

1. Set the pressure switch OFF/AUTO lever to the "OFF" position.

2. Plug the power cord into the correct branch circuit receptable.

3. Turn the regulator clockwise, opening it full, to prevent air pressure build-up in the tank.

4. Move the OFF/AUTO level to "AUTO". The compressor will start.

5. Run the compressor for 15 minutes. Make sure the regulator is open and there is no tank pressure build-up.

6. After 15 minutes, close the regulator by turning it counter-clockwise. The air tank will fill to the cut-out pressure and then the motor will start.

Thanks for the step-by-step, Phil.

Yeah, I figure opening the draincock (really- who names these things?...) is easier than adjusting the regulator, too. Worked like a charm.

Thanks again!
