Choosing the Correct Tip
Understanding Tip Number
The last three digits of tip number (i.e.: XXX515) con-
tains information about hole size and fan width on sur-
face when gun is held 12 in. (30.5 cm) from surface
being sprayed.
Example: For a 10 - 12 in. (254 - 305 mm) fan width and
a 0.015 in (0.38 mm) hole size, order part number
XWD515.
Selecting Tip Hole Size
• Tips come in a variety of hole sizes for spraying a
range of fluids. The sprayer includes a 0.015 in.
(0.38 mm) tip for use in most spraying applications.
Use the table below to determine the range of rec-
ommended tip hole sizes for each fluid type.
• Consider coating and surface to be sprayed. Make
sure to use the best tip hole size for the coating and
best fan width for that surface.
• Tip hole size controls flow rate - the amount of paint
that comes out of the gun.
HINTS:
• As you spray, the tip wears and enlarges. Starting
with a tip hole size smaller than the maximum will
allow you to spray within the rated flow capacity of
the sprayer.
• Tips wear with use and abrasive paint and need
periodic replacement.
• Do not spray with worn spray tips. Poor spray pat-
tern quality will result.
Choosing Pressure Control Knob Setting
Recommendations of a starting point for determining the best set point for your sprayer and particular coating are
shown in the table below.
NOTE: Spraying with the 0.011 tip at high pressure settings may cause the motor to overheat. Shut down sprayer
until it cools and then spray at a lower setting.
