Spray Gun Setup
This spray gun is shipped from the factory designed for use as a
“non-bleeder”, which means you must pull the trigger on the gun for air to
flow through the gun. Non-bleeder operation requires an air compressor
that has a storage tank.
If your air compressor does not have a storage tank, the spray gun
needs to be set up as a “bleed type”, which means that air passes contin-
uously through the gun without pulling the trigger. To switch the spray gun
to a bleed type, set the gun up as follows:
1.
Screw out the large fluid control knob (A)
counterclockwise located on back of the spray gun.
2.
With a screwdriver, screw out the packing screw
assembly (B) counterclockwise. (Be careful: the internal
spring may pop out).
3.
Remove the spring (C).
4.
Carefully remove the brass air valve (D), being careful
not to lose the small spring (E) in the end.
5.
Remove the rubber washer (F) from the brass air valve.
6.
Re-assemble the brass air valve, spring, packing screw,
and fluid knob into the spray gun.
This spray gun is designed to operate in three distinct ways for dif-
ferent painting functions.
For use as External Mix Pressure Feed:
1.
Install the external mix nozzle (G) onto the end of the spray gun.
2.
Make sure that the socket head set screw (I) is in place in the cup cover.
NOTE: This set up is used when spraying medium bodied, fast-drying materials
such as lacquers and fast-drying enamels.
For use as Internal Mix Pressure Feed:
1.
Replace the external mix nozzle (G) with the internal mix nozzle (H).
2.
Make sure that the socket head set screw (I) is in place in the cup cover.
NOTE: This set up is used when spraying relatively thick, slow-drying materials
such as latex or oil based paints.
For use as External Mix Siphon Feed:
1.
Remove whichever nozzle is on the spray gun.
2.
Remove the setscrew (I) from the cup cover.
3.
Install the setscrew in the front of the gun where the nozzle was (see Figure 4).
4.
Install the external mix nozzle (G) onto the end of the spray gun.
NOTE: This set up is used when spraying light bodied enamels, lacquers and stains which
need to be atomized to provide very smooth surfaces.
Using a Pressure Tank
When using a pressure tank, remove the setscrew from the cup cover and put it into the
front of the gun at the liquid nozzle, as you would for External Mix/Siphon Feed (see Figure 4).
Remove the cup, liquid tube, cup cover and sleeve nut, then attach the paint hose (see Figure 5).
Spraying Instructions
1.
As a standard practice, drain water from the air compressor tank and air lines prior to use each day (reference
your compressor operators manual for detailed instructions).
NOTE: Failure to install appropriate water/oil
removal equipment may result in damage to the spray gun or workpiece (see Figure 1).
