Pressure Relief Procedure Adjusting the Air Regulator

1.Lock the gun trigger safety.

2.Close all bleed-type master air valves, including the bleed-type master air valve (3), supplied in your sys- tem. FIG. 2.

3.Turn the regulator T-handle all the way counterclock- wise if you are removing the air filter/regulator (1) bowl, or servicing the air filter/regulator.

4.Open any fluid shutoff valves.

5.Unlock the gun trigger safety.

6.Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.

7.Lock the gun trigger safety.

8.Open any fluid drain valves (required in your sys- tem), having a container ready to catch the drain- age.

9.Leave the drain valve(s) open until you are ready to spray again.

If you suspect that the spray tip 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 and relieve pressure gradually, then loosen completely. Now clear the tip or hose.

Use the bleed-type master air valve (3) to relieve air trapped between it and the pump when the valve is closed. This helps reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

1.To increase the regulated air pressure, turn the T-handle clockwise.

2.To decrease the regulated air pressure, turn the T-handle counterclockwise.

3.To lock the regulator setting, tighten the jam nut.

4.Slowly open the air filter/regulator (1), FIG. 2. Use the filter/regulator to control pump speed and fluid pressure. Always use the lowest air pressure neces- sary to get the desired results. Higher pressures cause premature tip and pump wear.
