operating the equipment. SAVE THESE INSTRUCTIONS.

This symbol indicates a hazardous situation, which, if not not avoided could result in death or serious injury.

To reduce the risks of fire or explosion, electrical shock and the injury to persons, read and understand all instructions included in this manual. Be familiar with the controls and proper usage of the equipment.

HAZARD: INJECTION INJURY

A high pressure paint 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 sprayer is 3300 PSI / 22.8

MPa uid pressure.

PREVENTION:

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

• Do not aim the gun at, or spray any person or animal.

• NEVER allow any part of the body to touch the uid stream. DO NOT allow body to touch a leak in the uid 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 pump off, and

release all pressure before servicing, cleaning the tip or

guard, changing tip, or leaving unattended. Pressure will

not be released by turning off the motor. The PRIME/

SPRAY valve or pressure bleed valve must be turned to

their appropriate positions to relieve system pressure.

Refer to the PRESSURE RELIEF PROCEDURE

described in this manual.

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

device.

• ALWAYS remove the spray tip before ushing 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. Do not use hose to lift or pull

equipment.

• NEVER use a spray gun without a working trigger lock and

trigger guard in place.

• All accessories must be rated at or above 3300 PSI / 22.8

MPa. This includes spray tips, guns, extensions, and hose.

• Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn off the unit and relieve the pressure in accordance with the PRESSURE RELIEF PROCEDURE described in this manual.

• Verify that all connections are secure before operating the

unit. Unsecured parts may eject at great force or leak a

high pressure uid stream causing severe injury.

• Always engage the trigger lock when not spraying. Verify

the trigger lock is functioning properly.

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.

HAZARD: HAZARDOUS VAPORS

Paints, solvents, insecticides, and other materials

can be harmful if inhaled or come in contact with the body. Vapors can cause severe nausea, fainting, or

poisoning.

PREVENTION:

• Use a respirator or mask if vapors can be

inhaled. Read all instructions supplied

with the mask to be sure it will provide the

necessary protection.

• Wear protective eyewear.

• Wear protective clothing as required by coating manufacturer.

HAZARD: EXPLOSION OR FIRE

Solvent and paint fumes can explode or ignite. Property damage and/or severe injury can occur.

PREVENTION:

• Provide extensive exhaust and fresh air introduction to keep the air within the spray area free from accumulation of ammable vapors. Solvent and paint fumes can

explode or ignite.

• Do not spray in a conned area.

• Avoid all ignition sources such as static electric sparks, open ames, pilot lights,

electrical appliances, and hot objects.

Connecting or disconnecting power cords or working light switches can make sparks. Paint or solvent owing through the equipment is

able to result in static electricity.

• Do not smoke in spray area.

• Fire extinguisher must be present and in good working

order.

• Place pump at least 25 feet (7.62 meters) 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.

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

• Use only conductive or grounded high pressure uid hose. Gun must be grounded through hose connections.

• For electric units — power cord must be connected to a

grounded circuit.

• Always ush unit into a separate metal container, at low pump pressure, with spray tip removed. Hold gun rmly

against side of container to ground container and prevent static sparks.

• Follow the material and solvent manufacturer’s warnings and instructions. 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.

• Use extreme caution when using materials with a ashpoint below 70ºF (21ºC). Flashpoint is the temperature that a uid can produce enough vapors to ignite.

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

• Use lowest possible pressure to ush equipment.

• Do not spray onto pump assembly.

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 exing your wrist.

NOTE: Turning the pressure up higher than needed to

atomize the paint will cause premature tip wear and additional overspray.

Pressure Relief Procedure

1. Lock the gun by turning the gun trigger lock to the locked

position.

2. Turn off the sprayer by moving the sprayer ON/OFF switch to the OFF position.

3. Turn off the engine by moving the engine ON/OFF switch to the OFF position.

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

5. Unlock the gun by turning the gun trigger lock to the unlocked position.

6. Hold the metal part of the gun rmly

to the side of a metal container to ground the gun and avoid a build up of static electricity.

7. Trigger the gun to remove any pressure that may still be in the hose.

8. Lock the gun by turning the gun trigger lock to the locked

position.

9. Move the PRIME/SPRAY valve to the PRIME position.

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.

Important Facts Concerning this Sprayer

This gas-powered sprayer contains a clutch that engages when the sprayer is pumping. The sprayer’s pressure control system

engages and disengages the clutch to control pressure. To

prevent unnecessary wear to the clutch, it is advisable to adjust

the engine speed and pressure setting to limit the amount of times the clutch engages and disengages. To reduce clutch

wear, refer to the following examples.

Example:

Operating one gun with a .019 tip — reduce the engine speed by adjusting the throttle to a low or medium setting and increase

pressure only until the heavy ends of the spray pattern have been eliminated.

Example:

Operating one gun with .029 tip — increase engine speed to a

higher setting and increase pressure until the heavy ends of the spray pattern have been eliminated.

Example:

Spraying light-bodied materials at low pressure — to reduce surging at the gun and to decrease clutch wear, reduce the

engine speed to idle and reduce pressure until the desired spray pattern is achieved.

Checking the Clutch Gap

1. Remove the plastic plug from the top of the clutch housing.

Look through the port to locate the clutch armature and

the clutch rotor.

2. Check the gap between the clutch armature and the clutch rotor using a .016” feeler gauge and a .035” feeler gauge.

a. Insert each feeler gauge through the port and into the gap

between the clutch armature and the clutch rotor. The .016” feeler gauge should t in the gap. The .035” feeler gauge should not t in the gap.

b. Pull the engine pull cord several times to rotate the clutch

armature, checking the gap with each feeler gauge between each pull.

c. If the .016” gauge does not t or the .035” gauge does

t at any checkpoint, the gap must be readjusted. This is

done by relocating the clutch hub and armature assembly

on the engine shaft. Refer to the “Removing/Replacing

the Clutch Armature Assembly” procedure.

Servicing the Fluid Section

Use the following procedures to service the valves and repack the uid section.

1. Using a Phillips screwdriver, remove the four front cover screws. Remove the front cover.

2. Start the engine (refer to the procedures in the Operation section of this manual). Turn the pressure control knob clockwise to its maximum pressure setting.

3. Toggle the sprayer ON/OFF switch between the ON and OFF positions in short bursts until the slider assembly and piston rod stop at the bottom of their stroke (in their lowest position).

4. Turn off the engine and perform the Pressure Relief Procedure.

Servicing the Valves

The design of the uid section allows access to the inlet valve and seat as well as the outlet valve and seat without completely disassembling the uid section. It

is possible that the valves may not seat properly because of debris stuck in the inlet valve seat or

outlet valve seat. Use the following

instructions to clean the valves and reverse or replace the seats.

NOTE: Keep the sprayer in

the upright position for this procedure.

1. Using a wrench, loosen

Consignes de sécurite important · Lire toutes ces consignes avant

d’utiliser l’appareil. GARDER CES CONSIGNES.

Indique une situation à risque, laquelle, si elle n’est pas évitée, peut entraîner des blessures graves, voire la mort.

Pour réduire les risques d’incendie ou d’explosion, de choc électrique et de blessure, vous devez lire et comprendre les directives figurant dans ce manuel. Familiarisez-vous avec les commandes et l’utilisation adéquate de l’équipement.

DANGER : INJECTION CUTANÉE

Le jet de haute pression produit par cet appareil peut transpercer la peau et les tissus sous-jacents, causant des blessures graves pouvant entraîner l’amputation.

NE PAS TRAITER ce type de BLESSURE COMME UNE SIMPLE COUPURE! Une amputation peut en résulter. ON doit consulter un médicin sur-le-champ.

La pression maximale de ce pulvérisateur est d’environ 3 300 PSI / 22,8

MPa.

MESURES PRÉVENTIVES :

• Ne pas pointer le pistolet vers une partie du corps.

• Ne pas pointer le pistolet vers une personne ou un animal; ne pas pulvériser non plus de produit dessus.

• NE JAMAIS mettre une partie du corps devant le jet de produit. NE JAMAIS toucher les fuites du exible de pulvérisation.

• NE JAMAIS mettre la main, même gantée, devant le pistolet (les gants n’offrent aucune protection contre les blessures par injection).

• TOUJOURS verrouiller la détente, arrêter la pompe et relâcher toute la pression avant d’effectuer la maintenance de l’appareil ou de le laisser sans surveillance, d’en nettoyer le protège-embout ou l’embout, ou de remplacer ce dernier. La pression ne sera pas relâchée par le simple arrêt du moteur; pour ce faire, on doit se servir du bouton PRIME/SPRAY (se reporter à la section Comment libérer la pression, du présent manuel).

• TOUJOURS s’assurer que le protège-embout est en place avant de pulvériser. Il est cependant à noter que, s’il assure une certaine protection, ce dispositif joue surtout un rôle préventif.

• TOUJOURS retirer l’embout avant de vidanger ou de nettoyer l’appareil.

• toujours inspecter le exible avant de commencer; celui-ci peut présenter des fuites attribuables à l’usure, à une exion excessibe ou à un traitement abusif, lesquelles fuites présentent des risques d’injection cutanée. Ne pas utiliser le exible pour soulever ou tirer l’équipement.

• NE JAMAIS utiliser de pistolet sans verrou de détente et protège-

doigts.

• Tous les accessoires (pistolets, embouts, rallonges, exibles etc.)

doivent pouvoir subir une pression nominale de 3 300 PSI / 22,8 MPa ou plus.

• Ne laissez pas l’appareil sous tension ou sous pression quand vous vous en éloignez. Quand vous n’utilisez pas l’appareil, éteignez-le et libérez la pression conformément aux instructions Comment libérer la pression, du présent manuel.

• Vériez que toutes les connexions sont bien serrées avant d’utiliser l’appareil. Toute pièce qui n’est pas xée solidement risque d’être projetée violemment ou d’entraîner la fuite d’un jet de liquide à une pression extrêmement élevée, ce qui pourrait

causer des blessures graves.

• Verrouillez toujours la détente quand vous ne pulvérisez pas. Vériez que le verrou de la détente fonctionne correctement.

REMARQUE À L’INTENTION DES MÉDECINS : Les injections cutanées sont des lésions traumatiques; il

importe donc de les traiter sans délai. On NE DOIT PAS retarder

cause, celle-ci n’étant conséquente que dans le cas d’injection directe de certains produits dans le système sanguin. Il pourrait s’avérer nécessaire de consulter un plasticien ou un spécialiste en chirurgie reconstructive de la main.

DANGER : ÉMANATIONS DANGEREUSES

Certains produits (peintures, solvants, insecticides ou autres) peuvent être nocifs s’ils sont inhalés ou entrent en contact avec l’organisme. Les émanations de ces produits peuvent provoquer de graves nausées, évanouissements

ou empoisonnements.

MESURES PRÉVENTIVES :

• Se servir d’un masque ou d’un respirateur s’il y a risque d’inhalation (lire toutes les directives concernant ces dispositifs an de s’assurer qu’ils offrent la protection requise).

• Porter des lunettes de protection.

• Porter les vêtements de protection prescrits par le fabricant du produit utilisé.

DANGER : EXPLOSION OU INCENDIE

Les émanations de certains produits peuvent exploser ou s’enammer, et risquent d’entraîner des dommages matériels ou de graves blessures.

MESURES PRÉVENTIVES :

• Un approvisionnement en air frais et une évacuation des gaz doivent être assurés an que l’air entourant la zone de pulvérisation soit libre de toute accumulation de vapeurs inammables.

• Ne pulvérisez pas dans une zone connée.

• Évitez toutes les sources d’inammation telles que les étincelles d’électricité statique, les appareils électriques, les ammes nues, les ammes 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. L’écoulement de peinture ou de solvant dans l’équipement peut produire de l’électricité

statique.

• Ne fumez pas dans la zone de pulvérisation.

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

• Placez la pompe à une distance minimale de 7,6 mètres (25 pieds) de l’objet à pulvériser dans une pièce bien ventilée (ajoutez une longueur de tuyau au besoin). Les vapeurs inammables 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 enammer 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.

• Maintenez la propreté de la zone et veillez à ce qu’elle ne

contienne pas de conteneurs de peinture ou de solvant, de

chiffons et autres matières inammables.

• 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.

• Pour les unités électriques — 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. Sachez ce que contiennent la peinture et les solvants pulvérisés. Lisez les ches de sécurité du matériel (MSDS) et les étiquettes apposées sur les conteneurs de peintures et de solvants.

• 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’enammer.

• 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 inammables.

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

• Ne pulvérisez pas le système de pompage.

Sécurité des moteurs à essence

Les produits chimiques contenus dans les vapeurs d’échappement de cet appareil sont reconnus par l’État de la Californie (États-Unis) comme étant cancérigènes. Ils peuvent également entraîner des anomalies congénitales ou d’autres dangers pour la santé.

• Les moteurs d’essence sont conçus pour fonctionner en

toute sécurité et avec une abilité maximale s’ils sont utilisés conformément aux instructions. Veuillez lire et comprendre le manuel de l’utilisateur du fabricant de moteur avant de faire fonctionner le moteur. Le non-respect de ces consignes peut entraîner des dommages matériels ou des blessures physiques

graves.

• Pour éviter tout risque d’incendie et fournir une ventilation adéquate, placez le moteur à une distance minimale de 1 mètre (3 pieds) des immeubles et d’autres équipements pendant son fonctionnement. Ne placez pas d’objets inammables à côté du

moteur.

• Tenez les enfants et les animaux domestiques à l’écart de la zone de travail; vous éviterez ainsi tout risque de brûlures sur les pièces chaudes du moteur et de blessures entraînées par les accessoires utilisés par le moteur pour son fonctionnement.

• Sachez comment arrêter rapidement le moteur, et assurezvous que vous avez bien compris le fonctionnement de toutes les commandes. Ne permettez jamais à une personne de faire fonctionner le moteur sans connaître les instructions nécessaires.

• L’essence est extrêmement inammable et explosive dans

certaines conditions.

• Remplissez le réservoir de carburant dans une zone bien ventilée, moteur arrêté. Ne fumez pas et évitez toutes ammes ou étincelles dans la zone de remplissage de carburant ou dans une zone de stockage du carburant.

• Veillez à ne pas faire déborder le réservoir de carburant. Après remplissage, assurez-vous que le bouchon du réservoir est solidement vissé.

• Faites attention à ne pas renverser de carburant lors du remplissage du réservoir. Les vapeurs ou les éclaboussures de carburant peuvent s’enammer. En cas d’éclaboussures, assurez-vous que la zone est bien sèche avant de faire démarrer

le moteur.

• Ne faites jamais fonctionner le moteur dans un endroit fermé ou conné. Les fumées d’échappement contiennent du monoxyde de carbone qui est un gaz toxique; une exposition prolongée peut entraîner une perte de conscience et peut s’avérer mortelle.

• Le silencieux devient très chaud pendant le fonctionnement et reste chaud quelque temps après l’arrêt du moteur. Faites attention à ne pas toucher le silencieux tant qu’il est chaud. Pour éviter des brûlures graves ou des risques d’incendie, laissez le moteur refroidir avant de le transporter ou de le ranger à l’intérieur.

• Ne transportez jamais le moteur si le réservoir est plein.
