hole size
Last two digits = tip hole size in thousands of an inch
Example: For a 10-12 in. (254-305 mm) fan width and a
0.017 in (0.43 mm) hole size, order part number
PST517, depending on your sprayer model number.
ti19498a
Selecting Tip Hole Size
•Tips come in a variety of hole sizes for spraying a
range of fluids. The sprayer includes a 0.017 in.
(0.43 mm) tip for use in most spraying applications.
Use the table below to determine the range of recommended 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
pattern 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.

fully clockwise (there should be no gap between retainer
teeth and metal valve housing).
NOTE: You may occasionally have to remove, rotate, and
reposition pressure control knob due to stop feature
molded into back of knob.
2.Rotate retainer back (counter-clockwise) until the first
instance that the line and mark are aligned.
3.The valve retainer should now protrude approximately 1/8
in. (.30 cm) out from metal valve housing. Your
prime/spray valve is now calibrated.

ti17036a
ti19712a
NOTE: If pin does not assemble, repeat steps 3 - 6 to
ensure pressure control is fully engaged with retainer.
IMPORTANT!
After assembly is complete, perform the following steps to
verify proper operation. If sprayer fails one of the steps, repeat
Pressure Control Knob procedure.
•Verify proper trigger lock operation. Slide trigger lock into
“locked” and “unlocked” position and pull trigger. Trigger
should not move in locked position and sprayer should run
in unlocked position.
•Visually inspect for gaps between enclosure halves. A gap
larger than 1/32 in. could be caused by a pinched wire. If
disassembly and inspection indicates that no wire has
been pinched, carefully reassemble and repeat
verification steps.
•Cordless Sprayers: Verify that battery freely slides onto
sprayer terminals and is locked when fully engaged.
•Verify belt hook operation (if applicable) by sliding hook
completely out and back inside.
•Fill material cup with water and verify unit primes and
sprays. Follow setup instructions in sprayer operation
manual for proper priming and spraying procedure.
•Rotate pressure control knob to make sure it can rotate
fully in both directions.
