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. See Reversible
Spray Tip Selection Chart, page 17.
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. Details on tip selection, tip wear, coat thickness,
etc. are provided on page 16.
NOTE: 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 11.
• Turning knob to the right (clockwise), increases
pressure at gun.
• Turning knob to the left (counter-clockwise),
decreases pressure at gun.
Getting Started
Use a piece of scrap cardboard to practice these basic
spraying techniques before you begin spraying the sur-
face.
• Hold gun 30 cm (12 in.) from surface and aim
straight at surface. Tilting gun to direct spray angle
causes an uneven finish.
• Flex wrist to keep gun pointed straight. Fanning gun
to direct spray at angle causes uneven finish.
Triggering Gun
Pull trigger after starting stroke. Release trigger before
end of stroke. Gun must be moving when trigger is
pulled and released.
Aiming Gun
Aim tip of gun at bottom edge of previous stroke, over-
lapping each stroke by half.
