Air Connection
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 causes “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 (sold separately) to connect to the air inlet
on the Spray Gun. First, wrap the 1/4” air connector (not included) with pipe thread seal
tape before threading it into the Air Inlet (36). Connect the Red Air Hose (41) to the Air
Outlet Connector (36). Attach the other end of the Red Air Hose (41) to the Air Inlet
(67) on the Gun.
2. Set the air pressure on your compressor to 50 to 70 PSI. Do not exceed the maximum
air pressure of 70 PSI. Also, set the air pressure on the Air Regulator to 10-30 PSI, as
shown on the Gauge (38).
3. Check the air connection for leaks and then disconnect the tool from the air source.
