Using Electrical Cords

Grounding and Electrical 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 120 Vac sprayer requires a 120 Vac, 60 Hz, 15A circuit with a grounding receptacle.

Never use an outlet that is not grounded or an adapter.

Extension Cord Requirements

Only use an extension cord with an undamaged 3-prong plug for 120 V.

When operating sprayer outdoors, use an extension cord suitable for outdoor use.

NOTE: When using an extension cord, always use a cord coupler or an extension cord with locking plugs to ensure that your sprayer maintains power during operation.

Your extension cord must have an adequate wire size (AWG or American Wire Gauge) to be able to carry the current that your sprayer draws. A smaller gauge number has a greater capacity than a large one. For example, 14 gauge wire has a greater capacity than 16 gauge wire. An undersized extension cord will result in a drop in line voltage and loss of power, overheating, and possible damage to equipment.

When using more than one extension cord, make sure each individual cord contains at least the minimum wire size needed. The table below shows the correct size to use depending on extension cord size and gauge. If you are unsure, it is better to use a heavier gauge than needed. Remember, a smaller number indicates a larger gauge wire.

Do not use the sprayer if the electrical cord has a damaged ground prong.

Power Cord

• Damaged or entangled cords increase the risk of electric shock.

• Do not abuse the sprayer cord.

• Do NOT use the cord for carrying, pulling, or unplugging the sprayer.

• Keep the cord away from heat, oil, sharp edges, and moving parts.

• Do not operate the sprayer with a damaged cord.

Choosing the Correct Tip

First digit when doubled = approximate fan width

515 tip has 10 - 12 in. fan width

515 tip has a 0.015 in. hole size

Last two digits = tip hole size in thousands of an inch

CoatingsThinner Thicker

Choosing the Correct Tip

Understanding Tip Number

The last three digits of tip number (i.e.: XXX515) contains information about hole size and fan width on surface when gun is held 12 in. (30.5 cm) from surface being sprayed.

Example: For a 10 - 12 in. (254 - 305 mm) fan width and a 0.015 in (0.38 mm) hole size, order part number XWD515.

Selecting Tip Hole Size

• Tips come in a variety of hole sizes for spraying a range of fluids. The sprayer includes a 0.015 in. (0.38 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.

Install Spray Tip/Guard Assembly (if not installed)

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1. Engage trigger lock and put prime/spray valve UP to release pressure.

2. Install spray tip filter to spray tip/guard assembly.

NOTE: Spray tip filter is reverse-threaded. Turn left (or counter-clockwise) to install. Turn right (or clockwise) to remove.

Getting Started with Basic Techniques

Use a piece of scrap cardboard to practice these basic spraying techniques before you begin spraying the surface.

• Hold sprayer 10 in. (25 cm) from surface and aim straight at surface. Tilting sprayer to direct spray angle causes an uneven finish.

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

NOTE: How fast you move the sprayer will affect spray application. If material is pulsating, you are moving too fast. If material drips, you are moving too slow. See Trouble- shooting, page 24.

NOTICE

Make sure spray tip filter is completely screwed into the spray tip/guard assembly to avoid damage to the filter. Do not use a damaged spray tip filter or poor sprayer performance may result.

Do NOT place hands in front of tip.

3. Screw spray tip/guard assembly onto sprayer. Tighten retaining nut until completely engaged with sprayer. Do not overtighten nut.

NOTICE

The spray tip is a permanently attached to the spray tip/guard assembly. Removal will result in damage.

Aiming Sprayer

Aim spray tip of sprayer at bottom edge of previous stroke, overlapping each stroke by half.

Spray Pattern Quality

A good spray pattern is evenly distributed as it hits the surface. Adjust pressure control knob so pressure is just high enough to spray without “tails”. If tails persist at highest pressure setting, a smaller spray tip is needed to spray the material or material may need to be thinned.

3. Aim sprayer at waste area, disengage trigger lock, and put prime/spray valve DOWN to spray position. Pull trigger to clear clog.

4. Engage trigger lock. Put prime/spray valve UP to release pressure and rotate spray tip back to SPRAY position.

Shutdown and Cleaning

For best results, do not spray more than one cup of water through the tip while cleaning. If more flushing is needed, remove the tip from the sprayer.

NOTICE

Failure to properly clean sprayer after each use will result in hardened materials, damage to the sprayer, and the warranty will no longer be valid. Do not store solvents other than mineral spirits in sprayer. Always flush with Graco Pump Armor prior to storage.

Flushing Sprayer

Use only water-based or mineral spirit-type materials with flash point greater than 100° F (38° C). Do not use

materials which state “FLAMMABLE” on the packaging. For more information about your material, request MSDS from distributor or retailer.

Use oil-based material outdoors or in a well-ventilated indoor area with a flow of fresh air.

Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area.

3. Remove flexible suction tube as shown below.

NOTICE

When removing flexible suction tube from sprayer, make sure to pull directly on top fitting of flexible suction tube. The tube will become damaged if pulled from bottom or on flexible portion.

4. Use screwdriver to pry flexible suction tube strainer from flexible suction tube.

5. Clean flexible suction tube and suction tube strainer with water (or flushing fluid) and a brush every time you flush the sprayer. Reconnect flexible suction tube and suction tube strainer and orient as shown.

NOTICE

Protect the internal parts of this sprayer from water. Do

not submerge the sprayer in cleaning fluid. Openings in shroud allow cooling of mechanical parts and electronics inside. If water or cleaning fluid gets into these openings, the sprayer could malfunction or become permanently damaged.

1. Engage trigger lock and pull prime/spray valve UP to release pressure.

6. Clean material cup if not using a liner, and fill with water or appropriate flushing fluid.

7. Reconnect material cup and shake sprayer to move clean water around and clean all areas inside of cup.

2. Remove material cup and return excess material to

proper container. If used, properly dispose the material cup liner.

10. Disengage trigger lock, reverse spray tip to UNCLOG position, and pull trigger for 5 seconds to prime sprayer.

11. Put prime/spray valve DOWN to spray position. Trigger sprayer into waste area until no paint appears in water or flushing fluid.

13. Engage trigger lock and put prime/spray valve UP to release pressure.

NOTE: Air vent holes or the air vent valve (as your model is equipped) allow air to flow into the material cup while spraying to prevent loss of fluid flow.

14. Remove material cup and discard used fluid. Use a soft brush to clean the black rubber inlet seal. If vent holes become clogged, use a paper clip to clear the holes.

15. Remove spray tip/guard assembly and clean with water or flushing fluid. A soft brush can be used to loosen and remove dried material if needed.

IMPORTANT! For best results, do not spray more than one cup of water through the tip while cleaning. If more flushing is needed, remove the tip from the sprayer.

12. If sprayer is not completely clean, repeat steps 4-9.

To avoid serious injury or damage to equipment, do not expose the sprayer electronics to flushing solvents. Keep sprayer at least 10 in. (25 cm) above the rim of the container when flushing.

Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area. When flushing with solvents, always ground the sprayer and waste container.

NOTICE

The spray tip is permanently attached to the guard. Removing the spray tip from the guard will result in damage to the spray tip/guard assembly. Do not store spray tip/guard assembly or flexible suction tube in solvent other than mineral spirits. Damage to parts may occur.

4. Position pressure control knob in fully clockwise position and press firmly onto retainer.

NOTE: You may have to rotate pressure control knob slightly counter-clockwise to fully engage pressure control knob with retainer.

Wiring

Align switch in enclosure, install control board, and route wires as shown below. NOTE: Make sure wires will not be pinched when enclosure halves are put together.

Pressure Control Knob

NOTE: Do not disassemble retainer from prime valve housing.

If you have done so, refer to the Parts List (page 19) to purchase the appropriate valve kit.

1. Use the pressure control knob as a tool to rotate retainer 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.

5. Install washer onto pressure control knob.

6. Install valve handle onto stem.

7. Insert pin into valve handle. Use pliers to press pin into hole.

NOTE: If pin does not assemble, repeat steps 3 - 6 to ensure pressure control knob 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.
