Safety Precautions

WARNING

CAUTION

WARNING

This manual contains information which must be read and understood before using the equipment. When you come to an area which has one of the following symbols, pay particular attention and make certain to heed the safeguard.

This symbol indicates a potential hazard which may cause serious injury or loss of life. Important safety information will follow.

This symbol indicates a potential hazard to you or to the equipment. Important information that tells how to prevent damage to the equipment or how to avoid causes of minor injuries will follow.

NOTE: Notes give important information which

should be given special attention.

This unit is provided witha a thermally protected automatic reset. If an overload occurs the thermally protected automatic reset disconnects the motor from the power supply.

• The motor will restart without warning when the protector automatically resets.

• Always disconnect the motor from the power supply before working on the equipment.

• When the thermally protected automatic reset disconnects the motor from the power supply, relieve pressure by turning the priming valve to PRIME.

• Turn the ON/OFF switch to OFF.

NOTE: The cause of the overload should be corrected

before restarting. See TROUBLESHOOTING.

HAZARD: Injection injury - A high pressure stream of

paint produced by this equipment can pierce the skin and underlying tissues, leading to serious injury and possible amputation.

DO NOT TREAT AN INJECTION INJURY AS A SIMPLE CUT! Injection can lead to amputation. See a physician immediately.

The maximum operating range of the gun is 2800 PSI fluid pressure.

PREVENTION:

• NEVER aim the gun at any part of the body.

• NEVER allow any part of the body to come in contact

with the fluid stream. DO NOT come in contact with a fluid stream created by a leak in the fluid hose.

• NEVER put your hand in front of the gun. Gloves will not provide protection against an injection injury.

• ALWAYS lock the gun trigger, shut the fluid pump off and release all pressure before servicing, cleaning the tip guard, changing tips, or leaving unattended. Pressure will not be released by turning off the engine. The PRIME/SPRAY knob must be turned to PRIME to relieve the pressure. Refer to the PRESSURE RELIEF PROCEDURE described in this manual.

• ALWAYS have the tip guard in place while spraying. The tip guard provides some protection against injection injuries but is mainly a warning device.

• ALWAYS remove the spray tip before flushing or cleaning the system.

• Inspect the paint hose before each use. The paint hose can develop leaks from wear, kinking and abuse. A leak is capable of injecting material into the skin.

• NEVER use a spray gun which does not have a trigger lock or trigger guard in place and in working order.

• All accessories must be rated at or above 2800 PSI. This includes spray tips, guns, extensions, and hose.

NOTE TO PHYSICIAN: Injection into the skin is a traumatic injury. It is important

to treat the injury surgically as soon as possible. DO NOT delay treatment to research toxicity. Toxicity is a concern with some coatings injected directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.

HAZARD: EXPLOSION OR FIRE - Solvent and paint fumes

can explode or ignite, causing property damage and/or severe injury.

PREVENTION:

• Exhaust and fresh air introduction must be provided to keep the air within the spray area free from accumulation of flammable vapors.

• Avoid all ignition sources such as static electricity sparks, open flames, pilot lights, hot objects, cigarettes, and sparks from connecting and disconnecting power cords or working light switches.

• Fire extinguishing equipment must be present and in good working order.

• Keep the pump away from the spray area to avoid solvent and paint fumes.

• High velocity flow of material through equipment may develop static electricity. The equipment being used, as well as objects in and around the spray area must be properly grounded to prevent static discharge and sparks.

• Use only conductive or grounded high pressure fluid hoses for airless applications. Be sure that the gun is grounded properly through hose connections.

• Follow the material and solvent manufacturer's safety precautions and warnings.

• When flushing equipment use the lowest possible pressure.

HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE

MATERIALS - May cause property damage or severe injury.

PREVENTION:

• Do not use bleach.

• Do not use Halogenated hydrocarbon solvents such as

methylene chloride and 1,1,1 - trichloroethane. They are not compatible with aluminum and may cause an explosion. If you are unsure of a material’s compatibility with aluminum, contact your coating's supplier.

• All hoses, swivels, guns, and accessories used with this unit must be pressure rated at or above 2800 PSI.

• Do not spray on windy days.

Grounding Instructions

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 can result in a risk of electric shock.

If repair or replacement of the cord or plug is necessary, do not connect the green grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin.

Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

This product is for use on a nominal 120 volt circuit and has a grounding plug that looks like the plug illustrated below. A temporary adapter which looks like the adapter illustrated in the figure below may be used to connect this plug to a 2 pole receptacle as shown if a properly grounded outlet is not available.

The temporary adapter should be used only until a properly grounded outlet as shown below can be installed by a qualified electrician. The green colored rigid ear lug or the grounding wire extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw.

Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A 14 or 12 gauge cord is recommended.

NOTE: Do not use more than 100 feet of extension

cord. If you need to paint further than 100 feet from your power source, use more paint hose, not more extension cord. Shorter extension cords will ensure maximum electrical power for proper operation.

Spraying Technique

The key to a good paint job is an even coating over the entire surface. This is done by using even strokes. Keep your arm moving at a constant speed and keep the spray gun at a constant distance from the surface. The best spraying distance is 10 to 12 inches between the spray tip and the surface.

Keep the spray gun at right angles to the surface. This means moving your entire arm back and forth rather than just flexing your wrist.

Overlap each stroke by about 30%. This will ensure an even coating. When you stop painting, lock the gun trigger lock, turn the

pressure control knob counterclockwise to its lowest setting and set the priming knob to PRIME. Turn the motor switch to OFF and unplug the sprayer.

If you expect to be gone more than 1 hour, follow the short term clean up procedure described in the CLEANUP section of this manual.

Practice

1. Be sure that the paint hose is free of kinks and clear of objects with sharp cutting edges.

2. Turn the pressure control knob counterclockwise to its to its lowest setting.

Pressure Control Knob

Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other.

Approximately

10 to 12 inches

Right way

Wrong way

The spray gun should be triggered by turning it on and off with each stroke. This will save paint and avoid paint buildup at the end of the stroke. Do not trigger the gun during the middle of a stroke. This will result in an uneven spray and splotchy coverage.

3. Turn the PRIME/SPRAY knob to SPRAY.

4. Turn the pressure control knob clockwise to its highest setting. The paint hose should stiffen as paint begins to flow through it.

5. Unlock the gun trigger lock by turning the switch so that it is parallel to the handle.

6. Trigger the spray gun to bleed air out of the hose.

7. When paint reaches the spray tip, spray a test area to check the spray pattern.

8. Use the lowest pressure setting necessary to get a good spray pattern. If the pressure is set too high, the spray pattern will be too light. If the pressure is set too low, tailing will appear or the paint will spatter out in gobs rather than in a fine spray.

PRIME

Follow these procedures when encountering problems indicated in the troubleshooting section.

Removing and Cleaning the Inlet Valves

1. Be certain that the sprayer is off.

2. Remove the inlet valve assembly using a 27 millimeter socket or box end wrench.

3. Test movement of the valve by pushing on it from the open end of the valve housing with a screwdriver or the eraser end of a pencil. It should move about 1/16 of an inch. If it does not move, it should be cleaned or replaced.

2. Leave the copper washer under the cap in place.

NOTE: If the copper washer falls out, be sure to

replace it with the same side up. The top will show the imprint of the end cap, while the bottom should be perfectly flat to match the seat in the pump casting.

3. Remove and clean the small spring inside the valve using a wire hook or tweezers. Replace the spring if it is broken or worn.

NOTE: This spring is manufactured to a very specific

tension. Do not put in an unauthorized substitute. See the paint pump assembly parts diagram for the proper replacement part number.

4. Remove the seat and ball assembly using a 3/8 inch allen wrench.

5. Clean all parts thoroughly. If the ball or seat show any sign of wear or damage, replace them with new parts. This carbide ball must seal tightly against its seat for the valve to function properly.

6. Cover all parts with a thin coat of light oil before reassembling.

7. Tighten the valve seat securely with the 3/8 inch allen wrench.

8. Drop in the valve ball.

9. Insert the protector and spring and replace the cap. Be sure that the copper washer is positioned properly and that the tongue on the cap fits inside the spring.

10. Tighten the cap securely with an adjustable wrench. Do not overtighten.

NOTE: The inlet valve must be oiled after every job.

This will reduce or eliminate priming problems the next time the sprayer is used.

4. Thoroughly clean the valve assembly with water or the appropriate solvent. Use a small brush.

5. If you have properly cleaned the valve and water drips out of the bottom, the valve is worn and needs to be replaced. A properly seated valve filled with water and held vertically will not drip.

6. Install a new or cleaned valve in the pump block and then fill the valve with light oil or solvent.

Removing and Cleaning the Outlet Valve

It may be necessary to remove and clean the outlet valve or to replace parts inside the valve worn out through normal use.

1. Remove the outlet cap with a wrench.

NOTE: Wear on the ball is almost impossible to

detect visually. To test for a worn outlet valve assembly, turn the pressure control knob clockwise to its highest setting and run water only through the sprayer for 10 to 15 minutes without triggering the gun.

If the valve is defective, the end cap will get very hot to the touch. If it is functioning properly, it will stay approximately the same temperature as the water running through it.

1. Flush the gun with solvent immediately after the work is completed.

2. Oil the sliding pins to prevent them from seizing up.

Should the spray tip become clogged, reverse the spray tip with the lever and pull the trigger. Once the obstruction comes out of the spray tip, release the trigger, reverse the spray tip back to the spray pattern setting, and resume spraying.

Do not attempt to clean the tip with your finger. Do not use a needle or other sharp pointed instrument to

clean the tip. The hard tungsten carbide is brittle and can be chipped.

Cleaning the Filter

Clean the filter with a brush dipped in solvent. Never poke the filter with a sharp instrument.

Changing the Filter

1. Pull the trigger guard forward so that it comes loose from the handle.

2. Unscrew the handle from the housing and remove the old filter.

3. Slide the new filter, taper end first, into the gun housing.

4. Replace the handle, washer and spring. Screw the handle into the housing until hand-tight. Replace the trigger guard.
