Air Connection

Spray Gun

1/4” NPS

For best service you should incorporate a regulator, and inline filter, as shown in the diagram above. Hoses, couplers, regulators, and filters are all available at Harbor Freight Tools.

Note: Compressor pumps discharge condensed water, oil, or other contaminants along with the compressed air. Condensation cause “fish eyes” to appear in paint patterns. To avoid this problem, install water/oil removal filters and controls (not included) as close to the Spray Gun as possible. If run through the Gun, water and oil will cause damage.

1.You will need to prepare a 1/4” air connector to connect to the air inlet on either the Large or Small Sprayers. First, wrap the Air Inlet (40 or 23a; shown on next page) with pipe thread seal tape before threading it into the 1/4” air connector. Connect the 1/4” ID Air Source Hose to the Spray Gun.

2.Set the air pressure on your compressor to the recommended pressure for the spray gun used, as mentioned on page 2. Do not exceed the maximum recommended air pressure of 40 PSI for the large gun and small gun.

3.Check the air connection for leaks and then disconnect the tool from the air source.

Note: This unit comes with a 1/4”-18 NPS (IN/OUT) x 25’ Recoil Air Hose which you may use to connect from the air inlet to the air hose/compressor to give you more

flexibility.
