Flush Spray Gun
Before running any paint through the spray gun:
1. Flush the gun with a solvent that is compatible with
the fluid to be sprayed, using the lowest possible
fluid pressure and grounded metal container.
2. Perform Pressure Relief Procedure; see page 11.
Install Spray Tip
1. Perform Pressure Relief Procedure; see page 11.
2. Install the spray tip (H) and the gasket (J) in the tip
retainer nut (K). Screw the assembly firmly onto the
gun. Tighten the assembly with a wrench. See FIG.
7.
Adjust Spray Pattern
1. To adjust the spray pattern direction with fan tips,
orient the slot in the tip horizontally for a horizontal
pattern and vertically for a vertical pattern. See Fig.
7.
2. Start the pump. Adjust the fluid pressure until the
spray is completely atomized. Use the lowest pres-
sure necessary to get the desired results. Higher
pressure may not improve the spray pattern and will
cause premature tip wear and pump wear.
3. The spray tip orifice and spray pattern angle deter-
mines the coverage and size of pattern. When more
coverage is needed, follow the Pressure Relief
Procedure, page 11, and install a larger spray tip
rather than increasing fluid pressure.
Adjust a Streaming Tip
Select a tip that will supply a stream at the required flow
rate at the lowest pressure.
