Grounding
Verify that the ground screw (GS) is attached and tight-
ened securely to the air motor. Connect the clamp (U) of
the static ground cable (H) to a true earth ground.
Motor Lubrication
Graco does not require lubrication beyond the grease
installed at the factory or through regular maintenance.
With good quality compressed air and normal ambient
conditions, air motors will run millions of cycles without
additional lubrication.
However, if any of the following criteria apply to your
system, you will benefit from installing an air line lubrica-
tor in the air line before the air motor, or from occasion-
ally adding oil to an air filter cup.
•
Air supply does not contain any oil.
•
Air supply is very wet.
•
Air supply is very dry.
•
Air motor is run at low air pressure.
•
Air motor is run in unusually hot or cold environ-
ments.
Accessories
Bleed-type master air valve
•
Required in your system to relieve air trapped
between it and the air motor when the valve is
closed.
•
Be sure the valve is easily accessible from the pump
and located downstream from the air regulator.
Air Regulator
Required in your system to adjust the air pressure to the
motor and • uid outlet pressure of pump. Locate it close
to the motor. Install a gauge to read air pressure.
Air Filter
Required in your system to remove harmful dirt and
moisture from compressed air supply. The minimum
recommended air • ltration is 40 micron.
Air Lubrication
237212 1” npt (f) accessory lubricator with a 16 oz.
bowl. See form 308169.
244841 Kit. Modular Lubricator. Use with XL Graco
spray packages with modular air controls. See form
3A0293.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from
splashing or moving parts.
