Spray Pattern Quality

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.

Assembly
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.
See "Strain the Paint" on page 11 for additional informa-
tion.
