GROUNDING
This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the electric current. This product is equipped with a cord
having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that
is properly installed and grounded in accordance with all local codes and ordinances.
• Improper installation of the grounding plug is able to result in a risk of electric shock.
• When repair or replacement of the cord or plug is required, do not connect the grounding wire to either
flat blade terminal.
• The wire with insulation having an outer surface that is green with or without yellow stripes is the
grounding wire.
• Check with a qualified electrician or serviceman when the grounding instructions are not completely
understood, or when in doubt as to whether the product is properly grounded.
• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.
• This product is for use on a nominal 120V circuit and has a grounding plug similar to the plug illustrated
in the figure below.

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 16.

Tip Selection
Selecting Tip Hole Size
Setup
Tips come in a variety of hole sizes for spraying a range
of fluids. Your sprayer includes an 0.015 in (0.38 mm) tip
for use in most spraying applications. Use the following
table 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
on page 16.
Reversible Tip Selection Chart
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.
• Maximum tip hole sizes supported by the sprayer:
– LTS 15: 0.015 in. (0.38 mm)
– LTS 17: 0.017 in. (0.43 mm)

✔
Consider coating and surface to be sprayed. Make sure
you use best tip hole size for that coating and best fan
width for that surface.
Tip Hole Size
Tip hole size controls flow rate - the amount of paint that
comes out of the gun.
HINTS:
• Use larger tip hole sizes with thicker coatings and
smaller tip hole sizes with thinner coatings.
• Maximum tip hole sizes supported by sprayer:
– LTS 15: 0.015 in. (0.38 mm)
– LTS 17: 0.017 in. (0.43 mm)
– ProLTS 17: 0.017 in. (0.43 mm)
– ProLTS 19: 0.019 in. (0.48 mm)
• Tips wear with use and need periodic replacement.
Fan Width
Fan width is the size of the spray pattern, which determines the area covered with each stroke. Narrower fans
deliver a thicker coat, and wider fans deliver a thinner
coat.
HINTS:
• Select a fan width best suited to the surface being
sprayed.
• Wider fans allow provide better coverage on broad,
open surfaces.
• Narrower fans provide better control on small, confined surfaces.
