Spraying Techniques

Preventing Excessive Tip Wear
• Spray should be atomized (evenly distributed, no
gaps at edges). Start at low pressure setting,
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.

NOTE: If tails persist when spraying at the highest pres-
sure, 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 applica-
tions.
NOTE: Motor only runs when gun is triggered. Sprayer
is designed to stop pumping when gun trigger is
released.
• Turning knob to right (clockwise), increases pres-
sure at gun.
• Turning it left (counter-clockwise), decreases pres-
sure.
• General spraying instructions are provided in Get-
ting Started section of this manual, page 14.
