Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 4.

1. Pump: Use a ground wire and clamp as shown in Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order part number 237569 Grounding Clamp and Wire.

4. Spray gun or dispensing valve: Ground through connection to a properly grounded fluid hose and pump.

5. Object being sprayed: Follow your local code.

6. Fluid supply container: Follow your local code.

7. Solvent pails used when flushing: Follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

8. To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.

2. Air and fluid hoses: Use only electrically conductive hoses.

3. Air compressor: Follow manufacturer’s recommendations.

Installation

Noise Reduction

Instruction Manual 307375 is supplied with this motor. It provides information on noise reduction.

The following are additional recommendations for Maximum Noise Reduction:

D The air line should be connected to the air motor

inlet with an electrically conductive flexible hose. Also, use flexible fluid outlet and suction hoses. Where possible, avoid using solid plumbing, which carries noise vibrations.

D Mount the air motor on resilient rubber pads, rather

than sheet metal.

D Determine minimum air inlet pressure and pump

cycle rate to achieve desired spray/dispensing results or minimum fluid pressure and flow. This will result in less system wear and less overall noise.

Air Motor Icing

Moisture in the compressed air can collect in the air motor and freeze, causing the motor to stall. This is called icing. If icing occurs, shut off the air supply and allow the ice to thaw.

To minimize icing, reduce the moisture in your compressed air supply by using an air dryer or a filter which traps water.

Slope the main air line slightly downward so water will collect at the end of the line, where it can be drained. Additionally, plumb each drop line from the top of the main air line. Install an automatic drain or a drain valve at the bottom of each drop.

Model 237000 Reduced Icing Air Motor allows you to divert a stream of air over the air valves. This flow of warm air prevents water from collecting and freezing. The amount of air is adjustable with a needle valve (88, see the parts drawing on page 22).

For additional help in designing your system, contact your Graco distributor.

Troubleshooting

Pressure Relief Procedure

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, including fluid injection, splashing in the

eyes or on the skin, or moving parts, always follow the Pressure Relief Procedure whenever you

D are instructed to relieve the pressure D shut off the pump D stop spraying/dispensing D check or service any of the system equipment D install or clean the spray tips/nozzles

1. Lock the gun/valve trigger safety.

2. Turn off the air to the motor.

3. Close the bleed-type master air valve (required in your system).

4. Unlock the gun/valve trigger safety. Hold a metal part of the gun/valve firmly to a grounded metal pail. Trigger the gun/valve to relieve pressure.

Stalled Motor

To restart a stalled motor, close the bleed-type master air valve to bleed off all trapped air pressure. Turn the air back on. This will trip the air valve of the air motor, causing the piston to go to the top or bottom of its stroke.

WARNING

MOVING PARTS HAZARD

The piston in the air motor moves when air is supplied to the motor. Moving parts

can pinch or amputate your fingers or other body parts. Relieve the pressure before servicing the motor.

If Motor Will Not Operate

Check the following areas for damage or wear and replace parts as needed.

5. Lock the gun/valve trigger safety.

6. Open the fluid drain valve. Leave the fluid drain valve open until you are ready to spray/dispense again.

If you suspect that the spray tip/nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly

loosen the tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose obstruction.

Air valving mechanism: director valve (3), spring (4), air valve housing (5), valve plate (2), valve plate seal (1).

Trip rod: check for broken spring or bent rod (40). Do not attempt to repair the trip rod.

Damaged toggle mechanism: guide (16), spring (17), housing (18), pin (19).

Troubleshooting

Air Leaks

Air leaks are caused by worn or damaged gaskets or seals. To locate the leaks, first shut off the air supply to the pump and open the bleed-type master air valve to relieve air pressure. Disconnect the main air supply line from the air inlet. Remove the shield (27) as explained on page 10, then reinstall the other parts and connect the main air line to the inlet.

Open the bleed-type master air valve and adjust the air pressure to .07–0.1 MPa, 0.7–1.0 bar (10–15 psi). Stall the pump on both the up and down stroke as indicated in the Check Chart below. Use the methods listed in the Check Chart to find where air is leaking. See Fig.

your fingers. Reinstall the air motor shield before resuming normal operation of the pump.

Check for air leaks by feeling, listening, or squirting oil around the suspected area. The oil will bubble if there is a leak.
