the pressure setting just until spray from
the

avoid excessive overspray and fogging, and to
decrease
tip wear and extend the life of the spray

If
more coverage is needed, use a larger tip rather
than
increasing the pressure.

engage the trigger safety latch
and loosen the retaining nut. Position the tip
guard
horizontally for a horizontal pattern or verti
