OPERATING INSTRUCTIONS

1.NOTE: Before starting, make sure to refer to both the spray gun and paint manufacturers’ instruction manuals to determine the proper level of air pressure required for each specific painting job that is to be performed.

2.To use the Air Regulator, turn its Adjusting Knob counterclockwise all the way. (See Figure A.) Apply several wraps of sealant tape to the threads of #13 Adapter. Then install a 1/4” NPT or 1/4” NPS coupler plug (not included) on the Adapter, and wrench tighten.

3.Connect the air supply hose to the Coupler (not included) of the Air Regulator. Then, turn on the air compressor. (See Figure A.)

4.IMPORTANT: The air pressure of the Air Regulator may be adjusted from 0 to 160 PSI. To increase the level of PSI, turn the Adjusting Knob (part #1) clockwise. To decrease the level of PSI, turn the Adjusting Knob counterclockwise. (See Figure A.)

5.Turn the Adjusting Knob (part #1) clockwise to raise the air pressure to the de- sired level as indicated on the Pressure Gauge (part #14). (See Figure A.)

6.Make sure to spray waste material for several seconds prior to starting the actual job. This allows you to properly adjust the spray gun and, if necessary, re-adjustthe level of air pressure using the Adjusting Knob (part #1).
