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 (C)
Adjusts air pressure to the motor and fluid outlet pressure of pump. Locate it close to the pump. Install a
gauge (D) to read air pressure.

Safety Relief Valve (M)
Automatically opens to relieve air pressure, to prevent
pump overpressurization.

Air Filter (E)
Removes harmful dirt from compressed air supply.
Graco recommends using an air filter with a minimum measurement of 40 micron.

311238ZAJ

Grounding

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 NXT 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 a 3/4 in. air line
lubricator in the air line before the air motor or from
occasionally 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 environments.

Areas that benefit from lubrication:
•
•
•

Add Accessory Air Lubricator
If using an air motor with integrated air controls, add an
accessory airline lubricator❄ to the motor inlet. The oil
will move through the air filter.
Depending on air quality you may need to change
the air filter more frequently.
❄ Graco offers airline lubricators for NXT air motors.
Order 214848 (1/2 in.) for NXT 2200 and NXT 3400
air motors. Order 214849 (3/4 in.) for NXT 6500 air
motors.
If using an air motor without integrated air controls, add
a standard type filter/regulator/lubricator that is sized for
the specific air motor, such as 217073 (3/4 in.) or
217072 (1/2 in.).

Grounding

main piston o-rings(17),
sliding valve spool(119/108), and
motor detent assembly (113).

Add Lubrication
The three methods for adding lubrication are described
below.
Lubricate Air Valve
Perform these steps annually, or more often depending
on your duty cycle, air pressure, and air quality. Use a
high quality lithium-based grease.
1. Remove the 10 air valve cover screws (124) and air
valve cover (112).
2. Grease all visible moving parts, especially detent
(113) and valve pistons (119).
Lubricate Air Filter Bowl

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.
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
See FIG. 2. Use the ground screw (60) and lockwasher
(61) to attach Part No. 244524 Ground Wire (GW) at the
rear of the air motor. Tighten the screw securely. Connect the other end of the ground wire to a true earth
ground.

60, 61

If using a motor with integrated air controls, add 50-75
ml of oil to the air filter bowl and run the motor for a few
minutes at a fast cycle rate. The oil will move through
the air valve and main piston.
It is normal for some oil to come out through the
exhaust.
