Adding Oil
1. The oil level should be at the center of the “full” level
on the Oil Sight Glass, as shown above. Add oil as
needed to maintain this level. Do not let the oil level
go below the center dot (LOW as shown below) and
do not overfill the oil so that it is above the center dot
(OVERFILL as shown below) on the Oil Sight Glass.
Oil Sight Glass (41)
Crankcase (44)

OIL LEVEL
2. To add oil:
a. Remove the Oil Plug (46).
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 Plug.
Cold Weather Operation
Premium quality 30-weight, non-detergent air
compressor oil (sold separately) is recommended
for use with this compressor. Start compressor in
heated area if outdoor temperatures drop below
32° F. If this is not practical, drain out the old
pump oil and use L-PAB100-150 Non-detergent
Air Compressor Oil in the pump crankcase instead
whenever the compressor’s temperature will fall
below 40°. Do not use multi-viscosity oil (such
as 10W-30), they leave carbon deposits on pump
components and lead to accelerated failure. Heavy
operation may require heavier viscosity oil.
3. If uncertain which oil to use for this compressor,
please call Harbor Freight Tools customer
service at 1-888-866-5797 for assistance.
WARNING!
To prevent serious injury from burns:
Do not add or change the oil while
the compressor is in operation.
Allow the compressor to cool before replacing oil.
Changing Oil
1. Place a container under the Drain Plug.
2. Remove the Oil Plug to allow air flow into the Pump.
3. Remove the Drain Plug, allowing the
oil to drain into the container.
4. When the oil is completely drained from
the Pump, replace the Drain Plug.
5. Fill the Pump with new compressor oil to
the FULL level on the Oil Sight Glass.
6. Replace and tighten the Oil Plug.
7. Discard the old oil according to local,
state and federal regulations.
Draining Moisture from the Tank
The Moisture Drain is located under the Tank.
It must be used daily to release all trapped air and
moisture from the Tank. Doing this will eliminate
condensation and prevent tank corrosion.
1. Turn the Power Switch of the compressor off.
2. Place a collection pan under the Moisture Drain.
3. Open the Moisture Drain two or three turns ONLY.
4. When all the pressure and moisture is released,
close the Moisture Drain.
Air Filter Maintenance
Check the Air Filter weekly to see if it needs
replacement. If working in dirty environments,
you may need to replace the filter more
often. To replace the Air Filter:
1. Unthread the Wing Nut holding the
Muffler Assembly in place.
2. Remove the Muffler Assembly.
3. Replace with a new Air Filter.
4. Secure in place with the Wing Nut.
