Understanding Tip Number
The last three digits of tip number (i.e.:413)
contain information about hole size and fan
width on surface when gun is held 12 in.

spraying a range of fluids. Your sprayer
includes a tip for use in most paint spraying
applications. Use the coatings table on page
17 to determine the range of recommended
tip hole sizes for each fluid type. If you need
a tip other than the one supplied, see the

hole size
Hints:
•
As you spray, the tip wears and
enlarges. Starting with a tip holesize
smaller than the maximum will allow
you to spray within the rated flow
capacity of the sprayer.
•
Use larger tip hole sizes with thicker
coatings and smaller tip hole sizeswith
thinner coatings.
•
Tips wear with use and need periodic
replacement.
•
Tip hole size controls flow rate - the
amount of paint that comes out of the
gun.
Fan Width
Fan width is the size of the spray pattern,
which determines the area covered with each
stroke.
Hints:
•
Select a fan width best suited to the
surface being sprayed.
•
Wider fans allow provide better cover-
age on broad, open surfaces.
•
Narrower fans provide better control on
small, confined surfaces.
