A good spray pattern is evenly distributed as it hits the sur- face. Adjust pressure control knob so pressure is just high enough to spray without “tails”. If tails persist at highest pressure setting, a smaller spray tip is needed to spray the material or material may need to be thinned.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1.To unclog spray tip clog, engage trigger lock and put prime/spray valve UP to release pressure.
