Open with knob or flat blade screwdriver to reduce icing.
If needed, adjust enough warm feed air bleed to elimi­nate icing.

Low noise models have exhaust baffles that can
accumulate ice easily.

Integrated Air Control Module
Accessory

Accessory Air Control Kits include air line compo­nents in an integrated assembly. Order the kits
separately. See manual 311239 for installation
instructions.

Bleed-type Master Air Valve (B)

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

• 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.

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:

• main piston o-rings(17),

• sliding valve spool(119/108), and

• motor detent assembly (113).

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

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

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.

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 F

IG. 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.

It is normal for some oil to come out through the
exhaust.
