INSTALLATION INSTRUCTIONS (CONTINUED)
Grounding
This product must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire
for the electric current if short circuit occurs. This product must be installed and operated with a power cord
or cable that has a grounding wire.
Install permanent wiring from the electrical source
to the pressure switch with a ground conductor
connected to the grounding screw on the pressure
switch. A properly sized cord with a ground conductor
and plug may also be installed by the user.
Installing Air Filter
Install air filter on pump (see Figure 13). Filter styles
may vary.
Lubrication

Recommended Oil (2 Options)
Single viscosity SAE 30 ISO100 nondetergent compressor
oil. Part number ST125303AV (0.5 qt) or ST126701AV (4
qt).
10W30 synthetic oil such as Mobil 1
Oil Capacity
Approximately 47.4 oz.
Remove oil fill plug on pump. Check oil level; some
models are shipped with oil in the pump. Add oil if
needed. Fill the pump with oil to the center of the
sight gauge using oil fill opening (see Figure 15).

through the breather cap opening as this may cause oil to
leak and spray out during operation.
Do not use regular automotive oil. Additives in
regular motor oil can cause valve deposits and
reduce pump life.
For maximum pump life, drain and replace oil after
the first 50 hours of run time and then follow the
regular maintenance schedule outlined later in the
manual.
This pump has an oil sight glass as shown in Figure
14. Oil level can be monitored and maintained as
shown in Figure 15.
NOTE: Some residual oil may still be in the pump
from factory testing leaving a thin coat on the sight
gauge; however, there is not enough oil to operate
the unit.
Improperly grounded electrical components are shock hazards. Make sure all the
components are properly grounded to prevent death or serious injury.
This unit contains no oil.
Before operating compressor, fill to
