Grounding and Electric

Requirements

Sprayer must be grounded. Grounding reduces the risk

of static and electric shock by providing an escape wire

for electrical current due to static build up or in the event

of a short circuit.

• This sprayer requires

a 120 Vac, 60 Hz,

15A circuit with a

grounding receptacle.

• Never use an outlet

that is not grounded

or an adapter.

• Do not use the sprayer if the

electrical cord has a damaged

ground prong.

• Only use an extension cord with

an undamaged 3-prong plug.

Recommended extension cords

for use with this sprayer:

• 50 ft (15.0 m) 14 AWG (2.1 mm

)

• 100 ft (30.0 m) 12 AWG (3.3 mm

)

Spray gun

: ground through connection to a properly

grounded fluid hose and pump.

NOTE: Smaller gauge or longer extension cords may

reduce sprayer performance.

Fluid supply container

: follow local code.

Solvent pails used when flushing

: follow local code.

Use only conductive metal pails, placed on a grounded

surface such as concrete. Do not place the pail on a

nonconductive surface, such as paper or cardboard,

which interrupts grounding continuity.

Grounding the metal pail

: connect a ground wire to the

pail by clamping one end to pail and other end to ground

such as a water pipe.

Maintaining grounding

continuity when flushing or

relieving pressure: hold metal

part of the spray gun firmly to

the side of a grounded metal

pail, then trigger the gun.

Thermal Overload

313036N 25

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.

Setup

1. Relieve Pressure, page 11.

2. Unplug electric cord.

3. Remove enclosure and disconnect motor leads from

control card.

4. Remove fan brace.

5. Remove four screws and front cover.

6. Remove yoke and guide rods.

7. Remove gear.

Armature Short Circuit Spin Test

Quickly turn motor fan by hand. There should not be

electrical shorts and fan should coast two or three

revolutions before stopping. If fan does not spin freely,

armature is shorted. Replace motor using Motor Kit,

page 28.

Armature, Brushes and Motor Wiring Open Circuit

Test (Continuity)

1. Connect red and black motor leads together with

test lead.

2. Turn motor fan by hand, about two revolutions per

second.

3. If there is an uneven resistance or no resistance,

replace motor using Motor Kit, page 28.

Pressure Control Switch Diagnostics

26 313036N

Pressure Control Switch Diagnostics

LTS 15, LTS 17, ProLTS 17 and ProLTS 19

If pressure control switch diagnostics reveal a damaged pressure control, replace it with the correct Pressure Con-

trol Switch Kit, see page 28. LTS 15 and LTS 17 sprayers have different pressure control kits because stall pres-

sure is preset at the factory.

1. Unplug power cord and Relieve Pressure, page 11.

2. If paint is leaking from pressure control switch

between pressure control knob and base, replace

pressure control switch.

3. ProLTS 17 and ProLTS 19: Remove front cover,

yoke, and pins. Disconnect pressure control switch

connector from control board.

LTS 15 and LTS 17: Remove enclosure and dis-

connect pressure control switch connector from

control 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.

6. Using ohmmeter to measure across two terminals in

pressure control connector. Continuity or closed cir-

cuit should exist when pressure control knob is set

at maximum pressure (full clockwise). Replace

pressure control switch if no continuity exists.

nectors for proper installation (see Wiring Diagram,

page 49).

3. Check fuse on control board. If fuse is blown, deter-

mine the cause before replacing control board (see

Advanced Troubleshooting, page 18).

Pump Diagnostics

When pump packings wear, paint begins to leak down

the outside of the pump. At the first sign of leakage,

replace the pump or additional damage to the drive train

could occur.
