Unpacking
1. Remove
all
packaging.
It may be necessary to brace or support one side of the 
outfit when removing the pallet because the air compressor 
will have a tendency to tip.
2. Remove and discard the (4) screws and washers holding the compressor to
the pallet.
3. With the help of another person carefully remove air compressor from pallet
and place on a level surface.
To Add Oil To Pump
Compressors are shipped with some oil due to factory 
testing. Do not operate this air compressor without adding 
the correct amount of oil to the pump crankcase. Serious damage can 
result from even the minimal operation if the pump crankcase does not 
contain the correct amount of oil. Make sure the break-in procedure is 
completed before operating the air compressor.
Multi-Viscosity motor oils, like 10W30, should not be used 
in an air compressor. They leave carbon deposits on critical 
components, thus reducing performance and compressor life. Use air 
compressor oil only.
NOTE: Oil is included with some units. If oil is not included, use an oil 
specifically formulated for use in an air compressor, such as Porter-Cable PAS1 
air compressor oil. Oil may be found at the store where the air compressor was 
purchased.
1. Place unit on a level surface. 
Drain tank to release air pressure before removing the oil fill 
cap or oil drain plug.
2. Remove oil fill plug (A) and slowly add a
A
B
compressor oil to the middle of sight 
glass (B). NOTE: 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 48 fluid ounces. 
3. Replace oil fill plug.
