How do I get an owners manual for a craftsman 3/4 hp air compressor model 919-150273

SOURCE: owners manual ruined. what type of oil do i fill w before use

you should be able to find the manual online if it's available if not Sears would I'm sure be able to tell you.

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.

SOURCE: Oil capacity for craftsman air compressor circa 1978 model #106..

I have a 2hp craftsman air compessor with a two cylinder pump, Here is the info from my manual as far as oil capacitity:

Remove oil fill plug and slowly add
a compressor oil until it is even with the
top of the oil fill hole. NOTE: Do not
allow oil to be lower than 3/8"
from the top at any time. When filling
the crankcase, the oil flows very slowly
into the pump. If the oil is added too
quickly, it will overflow and appear to
be full. NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.

I buy my compessor oil from Lowes in the tool department. It comes in 16oz and sells for about $3. I wouldnt worry about how many ounces it holds but rather that the oil level is to top of filler hole. Lowes also sells a synthetic oil for about $7 and is recommended for severe conditions (hot / cold / used all day). Good Luck!
