• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

• Always wear impervious gloves when spraying or cleaning equipment.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

8 311828H

Installation

Grounding

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.

Pump: Use the ground screw (GS) and lockwasher on the motor to attach a 244524 ground wire (Y). Tighten the screw securely. Connect the other end of the ground wire to a true earth ground.

Y

GS

Air and fluid hoses: use only electrically conductive hoses.

TI8250a

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See

Flushing, page 15.

Mounting Accessories

See Dimensions, page 24 and Mounting Hole Layouts, page 25.

F

IG

. 1 shows an air-powered system and FIG. 2 shows a

hydraulic-powered system.

Hoses

See FIG. 1 and FIG. 2. Be sure all hoses are properly sized and pressure-rated for your system. Use only electrically conductive hoses. Fluid hoses must have spring guards on both ends. Use a whip hose (P) and a swivel (R) between the main fluid hose (N) and the gun/valve (S) to allow freer gun/valve movement.

Air compressor or hydraulic power supply: follow manufacturer’s recommendations.

Spray gun: ground through connection to a properly grounded fluid hose and pump.

Fluid supply container: follow local code.

Object being sprayed: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun

firmly to the side of a grounded metal pail, then trigger the gun.

Installation

Air Line Accessories

For air-powered pumps, install the following accessories in the order shown in F sary.

NOTE: Accessory Air Control Kits are available for the NXT Air Motor. The kits include a master air valve (E), air regulator (F), and filter (J). Order the kit separately. See manual 311239 for information.

• Bleed-type master air valve (E): 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.

• Pump air regulator (F): to control pump speed and outlet pressure. Locate it close to the pump.

IG

. 1, using adapters as neces-

• Pressure reducing valve (H) with a drain line (E) runs directly to the hydraulic return line (D).

• Accumulator (J) reduces the hammering effect caused by the motor reversing direction.

• Return line shutoff valve (V) isolates the pump for service.

• Be sure your hydraulic power supply is equipped with a suction filter to the hydraulic pump and a sys- tem return line filter (W) of 10 micron size.

• Connect a 6 mm (1/4 in.) ID drain line (K) to the barbed fitting on the drip pan, and place the free end in a container to collect the drainage.

Operation

Pressure Relief Procedure

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

1. Engage trigger lock.

2. Shutoff the pump:

For air-powered pumps,

a.

master air valve.

b.

For hydraulic-powered pumps,

line shutoff valve (U) first, then close the return line shutoff valve (V).

3. Disengage the trigger lock.

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

close the bleed-type

close the supply

Trigger Lock

Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped.

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.

Operation

Startup

1. Connect the suction kit (T) to the pump's fluid inlet, and place the tube into the fluid supply.

2. Prepare the pump’s power source:

a.

For air-powered pumps,

(F). Open the pump's bleed-type master air valve (E).

b.

For hydraulic-powered pumps,

hydraulic fluid level before each use, and add fluid as necessary. Close the supply line shutoff valve (U) and the return line shutoff valve (V). Start the hydraulic power supply.

3. Hold a metal part of the gun (S) firmly to the side of a grounded metal pail and hold the trigger open.

4. Start the pump:

a.

For air-powered pumps,

ulator until the pump starts.

close the air regulator

check the

slowly open the air reg-

NOTE: If your pump accelerates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines with fluid, or flush and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid system.

Shutdown

Relieve the pressure, page 13. Stop the pump at the bottom of its stroke to prevent fluid from drying on the exposed displacement rod and damaging the throat packings.

b.

For hydraulic-powered pumps,

line shutoff valve (V) first, then slowly open the supply line shutoff valve (U).

5. Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed. Release the gun trigger and lock the trigger safety latch. The pump should stall against pressure when the trigger is released.

6. With the pump and lines primed, and with adequate air or hydraulic pressure and volume supplied, the pump will start and stop as the gun is opened and closed. In a circulating system, the pump will speed up or slow down on demand, until the air or hydraulic supply is shut off.

7. Always use the lowest air or hydraulic pressure necessary to get the desired results. Higher pressures cause premature tip/nozzle and pump wear.

a.

For air-powered pumps,

to control the pump speed and fluid pressure.

b.

For hydraulic-powered pumps,

pressure gauge (F) and flow control valve (G) to control the pump speed and the fluid pressure.

use the air regulator (F)

open the return

use the fluid

8. Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself.

Maintenance

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.

Wet-Cups

Check the wet-cup daily. Keep the wet-cup 1/3 filled with

™

Graco Throat Seal Liquid (TSL

) or compatible solvent.

Flushing

• Flush before changing colors, before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment.

• Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary.

• Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

1. Follow Pressure Relief Procedure, page 13.

2. Remove spray tip and soak in solvent.

7. Follow Pressure Relief Procedure, page 13, and remove fluid filter and soak in solvent. Replace filter cap.

Corrosion Protection

Always flush the pump before the fluid dries on the displacement rod. Never leave water or water-based fluid in the pump overnight. First, flush with water or a compatible solvent, then with mineral spirits. Relieve the pressure, but leave the mineral spirits in the pump to protect the parts from corrosion.

Hydraulic Systems

NOTICE

Keep the hydraulic supply system absolutely clean at all times. Blow out hydraulic lines with air and flush thoroughly with solvent before connecting to the hydraulic motor, to avoid introducing harmful contaminants into the motor. Plug the hydraulic lines immediately when they are disconnected.

Do not exceed 37.8 liter/min (10 gpm) hydraulic oil volume to the motor, to avoid stalling the pump.

Do not exceed 54°C (130°F) hydraulic oil temperature.

Carefully follow the manufacturer's recommendations on reservoir and filter cleaning, and periodic changes of hydraulic fluid. Use only Graco-approved hydraulic oil. Order Part No. 169236, 5 gal. (19 liter) or 207428, 1 gal. (3.8 liter). Do not substitute a lower grade oil or one with a lower flash point.

3. Place siphon tube in grounded metal pail containing cleaning fluid.

4. Set pump to lowest possible fluid pressure, and start pump.

5. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun until clean solvent dispenses.

6. Remove gun from hose. See gun manual to further clean gun.
