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)

Choosing the Correct Tip
✔
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.

Warnings
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. Refer
back to these warnings. Additional, product specific warnings may be found throughout the body of this manual
where applicable.
WARNING
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.

Motor Diagnostics (LTS 15 and LTS 17)
Motor Diagnostics (LTS 15 and LTS 17)
If Motor Diagnostics reveal a damaged motor or if motor brushes are shorter than 1/4 in. (6.4 mm) replace the motor
using Motor Kit, page 28.
Setup
1. Unplug power cord and Relieve Pressure, page 11.
2. Remove enclosure and disconnect two black motor
leads to control board (see Wiring Diagram, page
49).
3. Remove motor fan cover by gently prying up on
retention tabs on sides of motor. Motor shaft should
spin easily when turning fan. If motor shaft does not
turn easily, there is a problem with pump, gears, or
motor (see Troubleshooting, page 13).
4. Inspect motor windings for evidence of overheating.
If windings appear burnt and motor smells, replace
motor.
5. Use Ohmmeter to measure resistance across two
black motor leads. Resistance of motor should fall
within range of 1.5 to 4.5 ohms. If motor falls outside
resistance range or is open circuit, replace motor.
6. Use Ohmmeter to measure resistance of motor
leads to motor laminations. If resistance is not open
circuit, replace motor.
7. Inspect length of both brushes by looking at brush
torsion spring. If spring is not bottomed out in slot for
brush spring, brush length is acceptable. If brushes
are worn out, replace motor.
Motor Diagnostics (ProLTS 17 and ProLTS 19)
Check for electrical continuity in motor armature, windings and brush as follows:
If Motor Diagnostics reveal a damaged motor or if motor brushes are shorter than 1/4 in. (6.4 mm) or if the motor
shaft cannot turn, replace the motor using Motor Kit, page 28.

board. Use finger to support control board when
removing pressure control switch connector.
4. Use ohmmeter to check for no continuity between
sprayer ground and both pressure control terminals
in connector. If either pressure control switch lead is
shorted to ground, pressure control switch wires
have been pinched to ground during assembly and
pressure control switch needs to be replaced.
5. Use Ohmmeter to measure across two terminals in
pressure control connector. No continuity or open
circuit should exist when pressure control knob is at
lowest pressure setting (full counter-clockwise).
Replace pressure control switch if continuity exists.
