WARNING

HAZARD: Injection injury - A high pressure fluid stream

produced by this equipment can pierce the skin and underlying tissues, leading to serious injury and possible amputation. See a physician immediately.

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 unit is 2800 PSI / 19 MPa fluid pressure.

PREVENTION:

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

• NEVER allow any part of the body to touch the fluid stream. DO NOT allow body to touch a leak in the fluid hose.

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

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

•ALWAYS keep tip guard in place while spraying. The tip guard provides some protection but is mainly a warning device.

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

• Paint hose can develop leaks from wear, kinking and abuse. A leak can inject material into the skin. Inspect the hose before each use.

• NEVER use a spray gun without a working trigger lock and trigger guard in place.

• All accessories must be rated at or above 2800 PSI / 19 MPa. This includes spray tips, guns, extensions, and hose.

HAZARD: EXPLOSION AND FIRE - Solvent and paint

fumes can explode or ignite. Severe injury and/or property damage can occur.

PREVENTION:

• Provide extensive exhaust and fresh air introduction to keep the air within the spray area free from accumulation of flammable vapors.

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

•Do not smoke in spray area.

• Fire extinguisher must be present and in good working order.

• Place pump at least 20 feet (6.1 m) from the spray object in a well ventilated area (add more hose if necessary). Flammable vapors are often heavier than air. Floor area must be extremely well ventilated. The pump contains arcing parts that emit sparks and can ignite vapors.

• The equipment and objects in and around the spray area must be properly grounded to prevent static sparks.

• Use only conductive or grounded high-pressure fluid hose. Gun must be grounded through hose connections.

• Power cord must be connected to a grounded circuit.

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

important to treat the injury 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.

WARNING

• Always flush unit into separate metal container, at low pump pressure, with spray tip removed. Hold gun firmly against side of container to ground container and prevent static sparks.

• Follow material and solvent manufacturer's warnings and instructions.

• Use extreme caution when using materials with a flashpoint below 70° F (21° C). Flashpoint is the temperature at which a fluid can produce enough vapors to ignite.

• Plastic can cause static sparks. Never hang plastic to enclose spray area. Do not use plastic drop cloths when spraying flammable materials.

• Use lowest possible pressure to flush equipment.

GAS ENGINE (WHERE APPLICABLE)

Always place unit outside of structure in fresh air. Keep all solvents away from engine exhaust. Never fill fuel tank with a running or hot engine. Hot surface can ignite spilled fuel.

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.

DANGER — 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.

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 12 gauge cord is recommended. If an extension cord is to be used outdoors, it must be marked with the suffix WA after the cord type designation. For example, a designation of SJTW-A would indicate that the cord would be appropriate for outdoor use.

General Description

This fine finish spray system is versatile enough to use for low pressure fine finish work as well as high pressure airless spraying. The system includes a diaphragm paint pump and an air compressor that work together to provide this versatility.

Setup

Use this procedure to set up the spray system.

1. Make sure the pump ON/OFF switch and the compressor ON/OFF switch are in the OFF position.

2. Make sure the pressure control knob is turned fully counterclockwise to its lowest pressure setting.

3. Lock the gun by turning the gun lock nut clockwise (when looking from the back of the gun) until it stops. This closes the material valve in the gun.

4. Using a wrench, attach a minimum of 50’ of 1/4” nylon airless spray hose to the material outlet fitting on the pump. Tighten securely.

5. Attach the spray hose to the material inlet fitting on the spray gun. Using two wrenches (one on the gun and one on the hose), tighten securely.

Make sure all airless hoses and spray guns are electrically grounded and rated for at least 2800 PSI (19 MPa) fluid pressure.

WARNING

6. Attach the air hose to the air outlet fitting on the compressor. Tighten securely.

7. Attach the air hose to the air inlet fitting on the spray gun. Tighten securely.

Reversing the hose connections could result in serious injury. Make sure the airless spray hose is connected from the diaphragm pump to the material inlet fitting on the gun and the air hose is connected from the compressor to the air inlet fitting on the gun.

8. Make sure the electrical service is 120V, 15 amp minimum.

9. Plug the power cord into a properly grounded outlet at least 25’ from the spray area.

Always use a minimum 12 gauge, three-wire extension cord with a grounded plug. Never remove the third prong or use an adapter.

10. Firmly press the pusher valve button on the side of the pump housing to make sure the outlet ball valve moves freely.

Operation

Use the following procedures to operate the spray system.

Priming the Pump

Preparing to Prime

1. Fill the inlet valve with water or with a light household oil.

2. Make sure that the PRIME/SPRAY valve is set to PRIME and that the pressure control knob is turned counterclockwise to its lowest pressure setting.

3. Turn on the pump by moving the pump ON/OFF switch to the ON position.

4. Increase the pressure by turning the pressure control knob clockwise 1/2 turn.

5. Force the inlet valve to open and close by pushing on it with a screwdriver or the eraser end of a pencil. It should move up and down about 1/16 of an inch. Continue until water or oil is sucked into the pump. This will wet the moving parts and break loose any old paint residue.

6. Put the palm of your hand over the inlet. Turn the pressure control knob clockwise to its maximum setting. You should feel suction coming from the inlet valve. If you do not, refer to the “Removing and Cleaning the Outlet Valve” procedure in the Maintenance section.

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.

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

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.

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.

Keep stroke smooth and at an even speed.

Maintenance

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

Removing and Cleaning the Inlet Valve

1. Perform the Pressure Relief Procedure, turn off and unplug the unit.

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.

NOTE: The inlet valve must be oiled

after every job. This will reduce or eliminate priming problems the next time the unit is used as well as extend the life of the valve.

NOTE: Proper cleaning and oiling of the pump after

use are the most important steps to perform to insure proper operation after storage.

PRIME/SPRAY Val ve

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

5. If the valve has been properly cleaned 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 valve body with a wrench.

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

3. Remove the seat and ball assembly.

4. 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.

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

6. Drop in the valve ball.

7. Insert the protector and spring and replace the valve body. Be sure that the O-ring is positioned properly and that the tongue on the cap fits inside the spring.

8. Tighten the valve body securely with an adjustable wrench. Do not over-tighten.

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 pump 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.

NOTE: Align the ridge on the seat with the groove in

the pump housing when reassembling.

NOTE: This spring is manufactured to a very specific

tension. Do not stretch the spring. Do not put in an unauthorized substitute. See the paint pump assembly parts diagram for the proper replacement part number. An extra spring is included in the literature set.

• Le tuyau à peinture peut présenter des fuites dues à l'usure, aux pincements et aux mauvaises utilisations. Toute fuite peut entraîner une injection de produit dans la peau. Vérifiez soigneusement le tuyau avant chaque utilisation.

• N'utilisez JAMAIS un pistolet pulvérisateur qui n’est pas muni d’un dispositif de verrouillage ou d’un dispositif de protection en place.

•Tous les accessoires doivent pouvoir fonctionner à des pressions minimales de 2 800 PSI / 19 MPa. Cette remarque s’applique aux têtes de pulvérisation, aux pistolets, aux rallonges et aux tuyaux.

DANGER :EXPLOSION ET INCENDIE – Les émanations de

solvants et de peintures peuvent exploser ou s'enflammer causant des dégâts ou des blessures corporelles graves.

PRÉVENTION :

• Un approvisionnement en air frais et une évacuation des gaz doivent être assurés afin que l’air entourant la zone de pulvérisation soit libre de toute accumulation de vapeurs inflammables.

• Évitez toutes les sources d'inflammation telles que les étincelles d'électricité statique, les appareils électriques, les flammes nues, les flammes pilotes, les objets chauds et les étincelles pouvant se produire lors du branchement ou du débranchement des cordons d’alimentation ou des interrupteurs de lampes de travail.

• Ne fumez pas dans la zone de pulvérisation.

•Vous devez disposer d'un extincteur en bon état de marche.

REMARQUE À L’INTENTION DU MÉDECIN : L'injection de liquide dans la peau est une lésion

traumatique qu’il importe de traiter le plus tôt possible. NE retardez PAS le traitement pour rechercher la toxicité. La toxicité est à prendre en compte lorsque certains enduits sont injectés directement dans le sang. Il peut être recommandé de consulter un chirurgien plastique ou un spécialiste de chirurgie reconstructive de la main.

Français

• Placez la pompe à une distance minimale de 6,1 mètres (20 pieds) de l'objet à pulvériser dans une pièce bien ventilée (ajoutez une longueur de tuyau au besoin). Les vapeurs inflammables sont souvent plus lourdes que l'air. La zone proche du sol doit être extrêmement bien ventilée. La pompe contient des parties susceptibles de former un arc électrique qui peuvent provoquer des étincelles et enflammer les vapeurs.

• L'équipement et les objets présents dans et autour de la zone de pulvérisation doivent être correctement mis à la terre pour éviter la formation d'étincelles statiques.

• N'utilisez qu'un tuyau de liquide à haute pression conducteur ou relié à la terre. Le pistolet doit être relié à la masse par les raccords de tuyaux.

• Le cordon d’alimentation doit être branché sur un circuit relié à la terre.

•Vidangez toujours l'appareil dans un contenant en métal isolé, à une faible pression de pompe et lorsque la tête de pulvérisation a été enlevée. Tenez le pistolet fermement contre le côté du contenant pour mettre le contenant à la masse et éviter la formation d'étincelles statiques.

• Suivez les instructions et mises en garde du fabricant du solvant.

• Redoublez de prudence lorsque vous utilisez des produits dont le point d'éclair est inférieur à 21 °C (70 ºF)). Le point d'éclair est la température à laquelle un liquide peut produire assez de vapeurs pour s'enflammer.

• Les plastiques peuvent produire des étincelles statiques. N'accrochez jamais de revêtement en plastique pour circonscrire la zone de pulvérisation. N'utilisez pas de vêtements en plastiques lorsque vous vaporisez des produits inflammables.

• Utilisez la plus petite pression possible pour rincer l'équipement.

MOTEUR À ESSENCE (LE CAS ÉCHÉANT)

Placez toujours l'appareil à l'extérieur à l'air libre. Éloignez tous les solvants du conduit d'échappement du moteur. Ne remplissez jamais le réservoir de carburant lorsque le moteur est en marche ou chaud. Le carburant répandu sur le sol peut s'enflammer au contact de surfaces chaudes. Reliez toujours le câble de mise à la terre de la pompe à un objet mis à la terre. Veuillez consulter le manuel d'utilisateur du moteur pour de plus amples renseignements concernant les consignes de sécurité.
