Whats the benifit of an oil less air compressor

SOURCE: My craftsman 3 gal. air compressor, 921.153101 won't compress air

I WOULD TRY DISCONNECTING THE PIPING FROM THE HEAD DOWN TO THE TANK AND SEE IF ITS BLOWING AIR. COULD THE COMPRESSOR BE RUNNING BACKWARDS - YOU WOULD HAVE HAD TO CHANGE THE WIRING IN THE MOTOR.
VALVES IN THE HEAD COULD ALSO BE BROKEN. YOU CAN REMOVE THE INTAKE AND IT SHOULD **** YOUR FINGERS AT THE OPENING. HOPE THIS HELPS.

Dewalt recommends synthetic oil in their compressors. The dewlat part # 5130427-00 quart, and 5130702-00 for a 4oz size. Available at www.dewalt.com or their service center. I have been using the Lowes brand of synthetic compressor oil. Kobalt oil sells for about $7 and works great. If you do not use your compressor all day like I do, you can use the standard grade of Kobalt compressor oil that sells for around $3. Synthetic oil is for extreme conditions. Good Luck!

You can go to any Home Depot and buy compressor oil for your compressor. Your operators manual should tell you what the level should be, however if you don't have one, filling it with oil until it fills the glass tube about half way should be sufficient.

SOURCE: Compressor won't turn on

check to make sure the red handle switch in flipped down, and that the socket has power. if it is and still does not work, the black box (pressure relief valve) is jacked up. good luck trying to get parts. called the manufacture yesterday (July 28) and the company went out of business back in early 2008 and there are no parts that they can supply. i am now looking for another compressor.
