1. You will need to prepare a 1/4” air connector (sold separately) to connect to the air inlet on
either the Gravity Feed or Touch-up Sprayer. First, wrap the 1/4” air connector (not included)
with pipe thread seal tape before threading it into the Air Inlet (see below).
Connect the 3/8” ID Air Source Hose to the Spray Gun.
2. Set the air pressure on your compressor to 50 PSI. Do not exceed the maximum air
pressure of 50 PSI.
3. Check the air connection for leaks and then disconnect the tool from the air source.
For best service you should incorporate an oiler, regulator, and inline filter, as shown in the
diagram above. Hoses, couplers, oilers, regulators, and filters are all available at Harbor
Freight Tools.
