Compressor Pump Oil
Maintenance
Check oil periodically for clarity. Replace oil if it appears
milky or if debris is present, or every 6 months, or
100 hours of runtime, whichever comes first. In harsh
environments such as high heat or high humidity, you
will need to replace the oil more frequently.
Change the compressor oil after the first hour of
use to remove any debris.
Adding Oil
1.
Oil Sight Glass (19)
Crankcase (16)
OVERFILL
LOW
FULL
OIL LEVEL
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 above) and
do not overfill the oil so that it is above the center dot
(OVERFILL as shown above) on the Oil Sight Glass.
2. To add oil:
a. Remove the Oil Plug (17).
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
SAE 10W 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
1-800-444-3353 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.
