Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama­tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. Refer
back to these Warnings. Additional, product-specific warnings may be found throughout the body of this manual
where applicable.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help pre­vent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when flammable
fumes are present.

• Ground all equipment in the work area. See Grounding instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

SPECIAL CONDITIONS FOR SAFE USE

Equipment must comply with the following conditions to avoid a hazardous condition which can cause
fire or explosion.

• All label and marking material must be cleaned with a damp cloth (or equivalent).

• The electronic monitoring system is required to be grounded. See Grounding instructions.

SKIN INJECTION HAZARD

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like
just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not point gun at anyone or at any part of the body.

• Do not put your hand over the spray tip.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Do not spray without tip guard and trigger guard installed.

• Engage trigger lock when not spraying.

•Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin
and cause serious injury.

•Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

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.

(0.76 MPa, 7.6 bar) relief valve

• NXT031 with locking air regulator and 75 psi
(0.51 MPa, 5.1 bar) relief valve

• NXT021 with non-locking air regulator and 110
psi (0.76 MPa, 7.6 bar) relief valve.

Air Filter (E)

Removes harmful dirt from compressed air supply.

Graco recommends using an air filter with a mini­mum measurement of 40 micron.

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:

• 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.

Preventive Maintenance Schedule

The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.

Tools Required

• Flat blade screwdriver

• Phillips screwdriver

• 3/4 in. socket wrench

• 9/16 in. socket wrench

• 3/8 in. socket wrench

• Torque wrench

4. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure.

5. Engage the trigger lock.

6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to spray
again.

7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after follow­ing the steps above, VERY SLOWLY loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.

Pressure Relief Procedure

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

Do not lift or move motor while pressurized.

1. Engage the trigger lock.

2. Close the bleed-type master air valve.

3. Disengage the trigger lock.

1. Stop the pump at the middle of its stroke. Relieve
the pressure, page 19.

2. Disconnect the air line to the motor.

(75) onto the reed switch sensor about 2 in. (50 mm)
behind the connection (C).

6. Route the remote DataTrak wire harness (76) down
the front of the air valve and carefully slide the
grommet (G) into the slot (S) of the new air valve
cover (47). There should be about 3 in. (76 mm) of
wire extending out of the air valve cover.

7. Install the new air valve cover (47) with the screw
(45), positioning the wire harness (76) so it will not
be pinched.
