Spraying Techniques

Preventing Excessive Tip Wear
• Spray should be atomized (evenly distributed,
no gaps at edges). Start at low pressure set-
ting, increase pressure a little at a time until you
see a good spray pattern, without tails.
• Spray at lowest pressure that atomizes paint.
• If maximum sprayer pressure is not enough for
a good spray pattern, tip is too worn. See
Reversible Spray Tip Selection Chart, page 15.

If tails persist when spraying at the highest
pressure, a smaller tip is needed or the
material may need to be thinned.
Adjust Spray Pressure
This sprayer is set up for most airless spraying
applications. Details on tip selection, tip wear, coat
thickness, etc. are provided on page 14.
Motor only runs when gun is triggered. Sprayer
is designed to stop pumping when gun trigger
is released.
Align setting indicator with function symbol on
Pressure Control knob, page 9.
• Turning knob to right (clockwise), increases
pressure at gun.
• Turning it left (counter-clockwise), decreases
pressure.
• General spraying instructions are provided in
Getting Started with Basic Spraying Tech-
niques section of this manual, page 16.
