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.

• The 120 Vac sprayers require 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 mm2)

• 100 ft (30.0 m) 12 AWG (3.3 mm2)

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 continu-ity 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 OverloadMotor has a thermal overload switch to shut itself down if overheated. If unit overheats, allow approximately 45 minutes for unit to cool. Once cool, switch will close and unit will restart.

Prime and Flush Storage FluidNOTE: To spray lacquers with the ProLTS 17 and ProLTS 19, you must purchase lacquer conversion kit 256212, and follow priming procedure for oil-based materials. The LTS 15 and LTS 17 units are not intended for lacquers.

Before you use your sprayer for the first time or be-gin a new spraying project, you need to prime thesprayer and flush the storage fluid out of the spray-er.

Oil- or Water-based Materials• When spraying water-based materials, flush the

system thoroughly with water.• When spraying oil-based materials, flush the sys-

tem thoroughly with mineral spirits or compatible, oil-based flushing solvent.

• To spray water-based materials after spraying oil-based materials, flush the system thoroughly with water first. The water flowing out of prime tube should be clear and solvent-free before you begin spraying the water-based material.

• To spray oil-based materials after spraying water-based materials, flush the system thoroughly with mineral spirits or a compatible oil-based flush-ing solvent first. The solvent flowing out of the prime tube should not contain any water.

• When flushing with solvents, ground pail and gun. Read Grounding and Electric Requirements, page 7.

• To avoid fluid splashing back on your skin or into your eyes, always aim gun at inside wall of pail.

Install Tip and Guard on Gun


2. Verify tip and guard parts are assembled in order shown.

3. Screw tip and guard assembly on gun. Tighten retaining nut.

4. Make sure spray tip is pointing forward in spray posi-tion.

Spraying TechniquesPreventing 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.

NOTE: If tails persist when spraying at the highest pres-sure, a smaller tip is needed or the material may need to be thinned.

Adjust Spray Pressure

This sprayer is set up for most airless spraying applica-tions. Details on tip selection, tip wear, coat thickness, etc. are provided on page 15.

NOTE: Motor only runs when gun is triggered. Sprayer is designed to stop pumping when gun trigger is released.

Align setting indicator with function symbol on Pressure Control knob, page 10.

• Turning knob to right (clockwise), increases pres-sure at gun.

• Turning it left (counter-clockwise), decreases pres-sure.

• General spraying instructions are provided in Get-ting Started with Basic Spraying Techniques section of this manual, page 17.

Tip SelectionSelecting Tip Hole Size

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 Reversible Tip Selection Chart on page 16.

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)– ProLTS 17: 0.017 in. (0.43 mm)– ProLTS 19: 0.019 in. (0.48 mm)

Choosing the Correct TipConsider 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 deter-mines 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, con-fined surfaces.

Getting Started With Basic Techniques

313034G 17

Getting Started With Basic TechniquesUse a piece of scrap cardboard to practice these basic spraying techniques before you begin spraying the sur-face.

• Hold gun 12 in. (30 cm) from surface and aim straight at surface. Tilting gun to direct spray angle causes an uneven finish.

• Flex wrist to keep gun pointed straight. Fanning gun to direct spray at angle causes uneven finish.

Triggering GunPull trigger after starting stroke. Release trigger before end of stroke. Gun must be moving when trigger is pulled and released.

Aiming GunAim tip of gun at bottom edge of previous stroke, over-lapping each stroke by half.

Warnings

313036H 3

WarningsThe following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-tion 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.

WARNINGGROUNDINGThis 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 quali-

fied 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.

• Only connect the product to an outlet having the same configuration as the plug. • Do not use an adapter with this product.

Extension Cords:• Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that

accepts the plug on the product. • Make sure your extension cord is not damaged. If an extension cord is necessary, use 12 AWG

(2.5 mm2) minimum to carry the current that the product draws. An undersized cord results in a drop in line voltage and loss of power and overheating.

FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

• Do not spray flammable or combustible materials near an open flame or sources of ignition such as cigarettes, motors, and electrical equipment. For LTS 15 and LTS 17 models: only use water-based or mineral spirit-type materials with a flash point greater than 70° F (21° C).

• Paint or solvent flowing through the equipment is able to result in static electricity. Static electricity creates a risk of fire or explosion in the presence of paint or solvent fumes. All parts of the spray system, including the pump, hose assembly, spray gun, and objects in and around the spray area shall be properly grounded to protect against static discharge and sparks. Use Graco conductive or grounded high-pressure airless paint sprayer hoses.

• Verify that all containers and collection systems are grounded to prevent static discharge.

• Connect to a grounded outlet and use grounded extensions cords. Do not use a 3-to-2 adapter.

• Do not use a paint or a solvent containing halogenated hydrocarbons.

• Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area. Keep pump assembly in a well ventilated area. Do not spray pump assembly.

• Do not smoke in the spray area.

• Do not operate light switches, engines, or similar spark producing products in the spray area.

• Keep area clean and free of paint or solvent containers, rags, and other flammable materials.

• Know the contents of the paints and solvents being sprayed. Read all Material Safety Data Sheets (MSDS) and container labels provided with the paints and solvents. Follow the paint and solvents manufacturer’s safety instructions.

• Fire extinguisher equipment shall be present and working.

• Sprayer generates sparks. When flammable liquid is used in or near the sprayer or for flushing or cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.

SKIN INJECTION HAZARD

High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that injection occurs, get immediate surgical treatment.• Do not aim the gun at, or spray any person or animal.• Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with

any part of the body.• Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.• Use Graco nozzle tips.• Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while

spraying, follow the Pressure Relief Procedure for turning off the unit and relieving the pressure before removing the nozzle tip to clean.

• Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn off the unit and follow the Pressure Relief Procedure for turning off the unit.

• Check hoses and parts for signs of damage. Replace any damaged hoses or parts.• This system is capable of producing 3000 psi. Use Graco replacement parts or accessories that are

rated a minimum of 3000 psi.• Always engage the trigger lock when not spraying. Verify the trigger lock is functioning properly.• Verify that all connections are secure before operating the unit.• Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar with the controls.

Installation

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 mm2)

• 100 ft (30.0 m) 12 AWG (3.3 mm2)

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 OverloadMotor has a thermal overload switch to shut itself down if overheated. If unit overheats, allow approximately 45 minutes for unit to cool. Once cool, switch will close and unit will restart.

ti5573a

Operation

313036H 11

OperationSee Operation manual 312001 for basic information on sprayer set-up, flushing, and storage.

Trigger LockAlways engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped.

Pressure Relief ProcedureFollow this Pressure Relief Procedure whenever you stop spraying and before cleaning, checking, servicing, or transporting equipment.

1. Turn power switch OFF and unplug power cord.

2. Turn Prime/Spray valve to PRIME to relieve pressure.

3. Hold gun firmly to side of pail. Trigger the gun to relieve pres-sure.


NOTE: Leave Prime/Spray valve in the PRIME position until you are ready to spray again.

If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction. Read Unclogging Spray Tip instructions in the Sprayer or Gun Operation manual.

Control Board Diagnostics (ProLTS 17 and ProLTS 19)NOTE: Check for motor problems before replacing control board. A damaged motor may burn out a good control card.

Check for a damaged control board or pressure control switch as follows:

1. Relieve Pressure, page 11.

2. Unplug electrical cord.

3. Remove four cover screws and front cover.Remove motor enclosure.

4. Remove yoke and guide rods.

5. Remove gear.

6. Remove pressure control harness from control board. Using tip of small, flat blade screwdriver, press tab on right side connector to release.

7. Attach harness from a pressure control switch you know is functioning correctly to control board.

NOTE: Pressure control switch does not have to be installed in pump.

8. Turn pressure control adjustment knob (C) +to max-imum pressure setting.

9. Plug electrical cord into 120VAC receptacle.

10. Turn power switch (B) ON.

• If motor runs, replace pressure switch. Pressure Control Switch Kit, page 28.

• If motor does not run, replace control board repeat test. Control Board Kit, page 28.

Control Board Diagnostics (LTS 15 and LTS 17)NOTE: Check for motor problems before replacing control board. A damaged motor may burn out a good control card.

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

2. Remove enclosure and check all control board con-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.

1. LTS 15 and LTS 17: Replace pump using Pump Replacement (Complete). See List of Kits, page 28.

ProLTS 17 and ProLTS 19: Replace pump using Pump Repair kit. See List of Kits, page 28.

2. If there is no paint leakage, see Advanced Trouble-shooting, page 18. Pump may not be defective.

NOTICE

When repairing or cleaning the pump, never submerge pump in water or allow fluid to enter pressure control.
