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 tip is needed to spray the mate-
rial or material may need to be thinned.

6. If spray tip is still clogged, you may have to repeat
steps 1 - 5 and rotate the spray tip from SPRAY to
UNCLOG several times. Repeat step 1 to release
pressure, remove and clean spray tip filter, or replace
with new spray tip/guard assembly.

Turn left (or counter-clockwise) to install.
Turn right (or clockwise) to remove.
Make sure spray tip filter is completely screwed into the
spray/tip guard assembly to avoid damage to the filter.
Do not use a damaged filter or poor sprayer performance
may result.

rotate spray tip back to SPRAY position.
