WARNING
Fire and explosion hazard: Solvent and paint fumes can ignite or explode.
To help prevent a fire and explosion:
Use only in an extremely well ventilated area.
Eliminate all ignition sources; such as pilot lights, cigarettes and plastic drop cloths (static arc hazard). Do not plug or unplug power cords or turn lights on or off in spray area.
Ground Sprayer, object being sprayed, paint and solvent pails.
Hold gun firmly to side of grounded pail when triggering into pail.
Use only conductive airless paint hose.
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use could result in a chemical reaction, with the possibility of explosion.
To reduce risk of electric shock, use grounded outlet only. Shut
OFF and unplug when repairing.
Fluid injection and high pressure hazard: High pressure spray or leaks can inject fluid into the body.
To help prevent injection, always:
Engage trigger safety latch when not spraying.
Keep clear of nozzle and leaks.
Never spray without a tip guard.
Do PRESSURE RELIEF if you stop spraying or begin servicing sprayer.
Do not use components rated less than sprayer Maximum
Working Pressure.

If high pressure fluid pierces your skin, the injury might look like
“just a cut”. But it is a serious wound! Get immediate medical attention.
MISE EN GARDE
Danger d’incendie et d’explosion : les gaz de solvant et de peinture peuvent s’enflammer ou exploser.
Pour éviter les risques d’incendie et d’explosion :
N’utiliser l’appareil que dans une zone extrêmement bien aérée.
Éliminer toute source d’inflammation ; telle que veilleuses, cigarettes et arcs d’électricité statique créés par les toiles de peintre en plastique. Ne pas brancher et débrancher de cordons électriques, ou allumer et
éteindre des lumières dans la zone de pulvérisation.
Mettre à la terre le pulvérisateur, l’objet à pulvériser ainsi que les seaux de peinture et de solvants.
Tenir le pistolet fermement contre la paroi d’un seau mis à la terre lorsqu’on pulvérise dans le seau.
N’utiliser qu’un flexible pour peinture pulvérisée sans air.
Ne jamais utiliser de trichloroéthane 1,1,1, de chlorure de méthylène, d’autres solvants à base d’hydrocarbures halogénés, ni de produits contenant de tels solvants dans un équipement sous pression en aluminium. Cela pourrait provoquer une réaction chimique avec risque d’explosion.
Pour réduire le risque de décharge électrique, employez la sortie au sol seulement. Coupez et débranchez quand la réparation.
Danger d’injection de fluide et haute pression : la pulvérisation sous haute pression ou les fuites peuvent injecter des fluides dans le corps.
Pour éviter les risques d’injection, toujours :
Bloquer le loquet de sécurité de la gâchette à la fin de la pulvérisation.
Se tenir loin de la buse et des fuites.
Ne jamais pulvériser sans anti-gouttes.
DÉCHARGER LA PRESSION à la fin de la pulvérisation ou avant de réparer le pulvérisateur.
Ne pas utiliser de composants dont la pression nominale est inférieure à la pression maximale de service du système.
Ne jamais permettre aux enfants d’utiliser cet appareil.
Si un fluide haute pression perce la peau, la blessure peut paraître une “simple coupure” Mais il s’agit bien d’une lésion grave! Consulter immédiatement un médecin.

ADVERTÊNCIA
Perigo de incêndio e explosão: os solventes e os vapores da pintura poderão explodir ou incendiar.
Para ajudar a evitar incêndio e explosão:
Utilize unicamente em áreas extremamente bem ventiladas.
Elimine todas as fontes de ignição, tais como luzes piloto, cigarros e arcos de estática resultantes dos plásticos de proteção. Não ligue nem desligue os cabos de alimentação ou as luzes numa área de pulverização.
Ponha em contato com a terra o pulverizador, o objeto a ser pulverizado, e os baldes de tinta e de solventes.
Segure a pistola firmemente de encontro ao lado do balde em contato com a terra, quando estiver descarregando para dentro do mesmo.
Utilize somente tubos flexíveis condutores para pintura a alta pressão.
Não utilize 1,1,1-tricloroetano, cloreto de metileno, outros solventes de hidrocarbonetos halogenados ou líquidos contendo tais solventes em equipamento de alumínio pressurizado. Tal utilização poderá resultar numa reação química, com possibilidade de explosão.
Para reduzir o risco de choque elétrico, use a tomada aterrada somente. Feche FORA e desconecte ao reparar.
Perigo de injeção de líquidos à alta pressão: a pulverização ou vazamentos à alta pressão podem injetar líquido no corpo.
Para ajudar a evitar injeção de líquido, faça sempre o seguinte:
Engate o trinco de segurança do gatilho quando não estiver pulverizando.
Mantenha-se afastado dos bocais e locais onde há vazamentos.
Nunca pulverize sem que haja uma proteção na extremidade.
ALIVIE A PRESSÃO quando parar de pulverizar e antes de iniciar a manutenção do pulverizador.
Não utilize componentes com uma classificação inferior à do pulverizador
Pressão Máxima de Trabalho.
Nunca permita que crianças utilizem esta unidade.
Se o líquido a alta pressão penetrar na sua pele, o ferimento poderá parecer “simplesmente um corte”. Mas é um ferimento grave! Procure o médico imediatamente.
ADVERTENCIA
Peligro de incendio o explosión: Los gases de los disolventes y de la pintura pueden inflamarse o provocar una explosión.
Para prevenir incendios y explosiones:
Use únicamente en un área muy bien ventilada.
Suprima todas las fuentes de ignición; como luces piloto, cigarrillos y arcos estáticos de carpetas plásticas para protección contra pintura. No enchufe ni desenchufe cables de alimentación ni apague ni encienda las luces en un área de pulverización.
Ponga a tierra el pulverizador, el objeto que recibe el chorro pulverizado, las cubetas de pintura y disolvente.
Sostenga firmemente la pistola a un lado de la cubeta puesta a tierra cuando dispare dentro de ella.
Use solamente mangueras para pintura conductora sin aire.
No utilice nunca tricloretano-1,1,1, cloruro de metileno ni otros disolventes a base de hidrocarburos halógenos o fluidos que contengan dichos disolventes en un equipo a presión de aluminio. El uso de estas sustancias puede provocar una intensa reacción química, con riesgos de explosión.
Para reducir el riesgo de la descarga eléctrica, utilice el enchufe puesto a tierra solamente. Apague y desenchufe al reparar.
Peligro de inyección de fluido y alta presión: por la pulverización o las filtraciones a alta presión se pueden inyectar fluidos en el organismo.
Para prevenir la inyección en la piel, siempre:
Enganche el seguro del gatillo cuando no use el pulverizador.
No se acerque a la boquilla ni a las filtraciones.
Nunca aplique fluido pulverizado sin un guardaboquilla.
Realice el ALIVIO DE PRESIÓN si deja de pulverizar fluido o repara el pulverizador.
No use componentes de capacidad nominal inferior a la presión máxima de operación del pulverizador.
No permita que niños usen esta unidad.
Si fluido de alta presión le penetra la piel, la lesión podría parecer “sólo un corte”. ¡Es una lesión seria! Consulte de inmediato al médico.
