Porter-Cable C7550 - Manual (Page 9)

Multi-Viscosity
motor oils, like 10W
30, 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 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.

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

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.
