Figure 3
Proper Gun Orientation and Adjustments While Spraying
Atomizing Air Trigger Adjustment
See Figure 4. When you pull the trigger, it opens the air valve and starts
atomizing air flowing before pulling the needle off the seat and allowing fluid
to flow. This pre-air prevents any un-atomized fluid flow from the gun. To
change the pre-air flow, use this procedure.
1. Flush the spray gun with a solvent compatible with the paint used, then
stop the pump and relieve the fluid pressure.
2. Unscrew the spring cap (23) and pull out the spring and washers (24,
25, 26) and the needle assembly (27, 28, 32).
3. Hold the needle extension (27) with one wrench while loosening the
needle carrier (28) with another wrench.
4. Adjust the flow point as follows:
S
Screw out the needle (32) to allow more atomizing air to flow
S
Screw in the needle to allow less atomizing air to flow
5. Tighten the needle carrier securely to hold the needle.
6. Re-install the spring and washers, needle assembly, and spring cap.
