When unpacking, check to make sure the parts listed on pages 14 and 16 are included.
If any parts are missing or broken, please call Harbor Freight Tools at the number on the cover
of this manual as soon as possible.
Spray Gun
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.
