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.

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.

. 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

Phillips screwdriver
3/4 in. socket wrench
9/16 in. socket wrench
3/8 in. socket 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.

Lubricate the packings. Install the bumper (59).
Prior to series H air motors the u-cup (7) was installed between the leather packings (8).
2. Install the o-ring (17*) on the piston (4). Ensure the piston bumper (10) is in place.
It is normal for the o-ring (17*) to seem too large.
3. Install the piston assembly on the bottom cover (3), carefully sliding the adapter (A) and shaft (S) through the packings.
4. Grease the inside of the cylinder (2). Place the cylin­der (2) over the piston (4). Be careful not to damage the o-ring (17*). Slowly work the o-ring into the
