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.

Gaskets are included with Streaming Tips 270XXX or Fan Tips 182XXX.

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.
