Checking The Oil - CentralPneumatic 60638 Owner's Manual

Installation (continued)
6. Pull the Compressor Pump until properly
aligned, and the belt is tight. Recheck the motor
pulley, V-belt, and Pump Pulley alignment.
7. Use mounting holes in the Compressor Pump
base as a template to mark the spots where four
holes will be drilled in the mounting surface.
8. Move the Compressor Pump aside and drill four
5/16" diameter holes in the mounting surface.
9. Move the Compressor Pump back to its mounting
position and secure each corner of the base
with a 5/16" diameter grade 5 or better bolt,
washer, lock washer, and nut (all not included).
10. Make final alignment and adjust belt tension with
the motor. It may be necessary to loosen the motor
mounting bolts to adjust the motor location. To test
the proper tension on the V-belt, press down on
the belt — there should be 1/2" deflection or less
at mid span. Tighten all mounting hardware.
11. Connect plumbing hardware (not included)
from the male 3/4"–14 NPT Air Outlet (51)
to the air destination (i.e., air pressure tank
of the compressor, not included), routing
the tubing in the shortest possible path.

checking the Oil

1. Check the oil level before operation.
Fill the Pump Crankcase with
SAE 30W, non-detergent,
Air Compressor Oil (sold separately).
IMPORTANT: Running the Air compressor
Pump with no oil or low oil will cause damage
to the equipment and void the warranty.
2. The oil level should be at the center of the FULL level
on the oil level sight glass, as shown in Figure C.
Add oil as needed to maintain this level.
Do not let the oil level go below the center
dot (LOW as shown in Figure C) and do not
overfill the oil so that it is above the center dot
(OVERFILL as shown in Figure C) on the sight glass.

12. Depending on the tool which you will be using
with this Compressor Pump, you may need to
incorporate additional components, such as an
in-line oiler, a filter, or a dryer (all sold separately),
as shown on Figure D on page 9 and
Figure E on page 10. Consult your air
tool's manual for needed accessories.
13. Install a safety guard (not included) that surrounds
the motor pulley, V-belt, and Pump Pulley. This
safety guard must cover all sides of the moving
belt and pulleys. It should have a clearance of
about one inch from the moving parts. The safety
guard must be sturdy enough to prevent injury.
WARNING! Avoid serious injuries. Do not
operate this Air compressor Pump without
a safety guard in place.
14. To operate, fill the Compressor Pump Crankcase
with Air Compressor Oil (sold separately) following
the directions in the next section. Then follow the
manufacturer's operating instructions and safety
warnings applicable to your air compressor.
3. To add oil:
a. Remove the Oil Fill Plug.
b. Using a funnel to avoid spills, pour enough
oil into the Pump Crankcase to reach the
FULL level in the Oil Sight Glass.
c. Replace the Oil Fill Plug.
Note: SAE 30W, non-detergent,
Air Compressor Oil (sold separately) is
recommended for use with this compressor.
4. If uncertain which oil to use for this compressor,
call Harbor Freight Tools customer service
at 1-800-444-3353 for assistance.
5. change the compressor oil after the first
hour of use to remove any debris.
cAUTION! TO PREVENT INJURy FROM BURNS:
Do not add or change the oil while
the compressor is in operation.
Allow the compressor to cool before replacing oil.
Note: This pump will consume oil during
operation, so check oil level before every use.
