SHUT DOWN PROCEDURES FOR SPRAY EQUIPMENT
1. Trigger gun until pump shaft is in the full down position (at bottom of stroke
position).
2. Engage gun trigger lock.
3. Relieving pressures:
a. Close main air valve to system.
b. Purge excess air from system by relieving air from the bottom of the air
filter or water trap.
c. Catalyst pressure: “Dump” or relieve catalyst pressure at catalyst
manifold (if applicable) by opening catalyst ball valve. Pressure will
immediately be relieved. Close the ball valve at once to avoid draining of
catalyst from catalyst line.
d. Material pressure: Place a container under material ball valve at bottom of
fluid filter assembly to catch material flow when relieving pressure.
Slowly open material ball valve to relieve pressure.
Remember - the pump is under extreme pressure. Use the utmost caution when
opening the valve to avoid injury or being sprayed with material. Once material
pressure is relieved, close ball valve.
4. Remove catalyst and material tip assemblies or nozzle and mix chamber from
head of gun and clean thoroughly.
5. Thoroughly clean diffuser cavity in front of gun head / clean gun block face.
6. Inspect entire gun and equipment for over spray and clean.
7. Relieve flush pressure by lifting the ring on the flush tank relief valve.
System is now “shut-down” and ready for the next start-up
Important Notes:
• When cleaning gun with solvents, avoid getting solvent in exhaust port of “air
trigger” gun by covering port with thumb or finger while cleaning and pointing gun
downward.
• Proper cleanliness habits of your spray equipment goes a long way in keeping
down unnecessary maintenance and repair costs.
