!ADVERTENCIA

Al soldar con arcos eléctricos puede causar chispas y calentar el metal a temperaturas que le

podrían ocasionar quemaduras graves! Use guantes y ropa de protección para hacer este tipo de trabajo. Tome todas las medidas de precaución descritas en este manual para reducir las posibilida-des de quemarse la piel o la ropa.

Cerciórese de que todas la personas que se encuentren en el área de trabajo estén protegidas contra el calor, las chispas, y los rayos ultravioletas. Igualmente debe utilizar protecciones adicionales cuando sea necesario.

Nunca toque las piezas que ha soldado hasta que éstas se hayan enfriado.

!ADVERTENCIA

El calor y las chis-pas producidas al soldar con arcos eléctricos y otros trabajos con metales

podrían encender materiales inflamables o explosivos! Tome todas las medidas de precaución descritas en este manual para reducir las posibilidades de llamas o explosiones.

Mueva todos los materiales inflamables que se encuentren en un radio de 35 pies (10,7 metros) del arco de soldadura. Si no lo puede hacer, deberá cubrirlos con algún material que los aisle del fuego.

No use una soldadora eléctrica de arco en áreas donde pueda haber vapores inflmables o explosivos.

Tome todas las precauciones necesarias para evitar que las chispas y el calor ocasionen llamas en áreas poco accesibles, ranuras, detrás de divisiones, etc.

!ADVERTENCIA

Peligro de in-cendio! Nunca debe soldar envases o tuberías que contengan o hayan contenido materiales inflamables o combustibles gaseosos o líquidos.

!ADVERTENCIA

Al soldar con arcos eléctricos cilindros cerrados o tambores

podría ocasionar explosioones si no están bien ventilados ! Cerciórese de que cualquier cilindro o envase que vaya a soldar tenga un orificio de ventilación para que los gases puedan liberarse.

!ADVERTENCIA

No debe respirar los gases emitidos al soldar con arcos eléctricos. Estos son peligrosos.

Si no puede ventilar bien el área de trabajo, deberá usar un respirador.

Mantenga la cabeza y la cara alejada de los gases emitidos.

No debe soldar con arcos eléctricos metales galvanizados o con capa de cadio, o aquellos que contengan zinc, mercurio o berilio sin tomar las siguientes precauciones:

a.Quitarle la capa al metal.

b.Cerciorarse de que el área de trabajo esté bien ventilada.

c.Usar un respirador.

Estos metales emiten gases sumamente tóxicos al calentarse.

!ADVERTENCIA

El campo electromagnetico generado al soldar con arcos eléctricos podría interferir con el funcionamiento de varios artefactos eléctricos y eléctronicos tales como marcapasos. Aquellas personas que usen estos artefactos le deben consultar a su médico antes de soldar con arcos eléctricos.

Coloque los electrodos y cables en la misma línea y únalos con cinta pegante cuando sea posible.

Nunca se enrolle los cables de la soldadora en el cuerpo.

● Siempre coloque los electrodos y las conexiones a tierra del mismo lado.

● El exponerse a campos electromag- neticos al soldar con arcos eléctricos le podría ocasionar otros problemas de salud desconocidos hasta el momento.

! ADVERTENCIA Cerciórese

de que el

área de trabajo este libre de peligros (chispas, llamas, metales al rojo vivo o escorias) antes de irse. Cerciórese de que ha apagado la soldadora y le ha quitado el electrodo. Cerciórese de que los cables estén enrollados y almacenados. Cerciórese de que tanto el metal como la escoria se hayan enfriado.

! ADVERTENCIA

Este producto, cuando se usa para soldar, produce humos o gases que contienen químicos los cuales, según lo ha determinado el estado de California, cuasan defectos congénitos (u otros daños de la función reproductiva), y en algunos casos, el cáncer (Ley sobre Seguridad y Salud de California No. 25249.5 y siguientes).

MEDIDAS DE SEGURIDAD

ADICIONALES

Aquellas personas que vivan y trabajen en los Estados Unidos deben percatarse de que según las leyes de este pais los siguientes códigos aplican para el trabajo con soldadoras: ANSI Standard Z49.1, OSHA 29 CFR 1910, NFPA Standard 70, CGA Pamphlet P-1, CSA Standard W117.2, NFPA Standard 51B ANSI Standard Z87.1. Aquellas personas que residan en paises latinoamericanos deben consultar los códigos y regulaciones que se apliquen en sus respectivos paises.

One of the standout features of the WS2800 is its powerful 2800 PSI (pounds per square inch) water pressure. This level of pressure allows users to effectively remove dirt, grime, and stains from a variety of surfaces, including driveways, patios, decks, and vehicles. Additionally, it offers a flow rate of 2.4 GPM (gallons per minute), ensuring that the cleaning process is both thorough and efficient.

The WS2800 integrates advanced technology to enhance user experience. It comes equipped with a powerful 1800-watt electric motor, which provides reliable and consistent performance. Unlike gas-powered pressure washers, the electric motor ensures quiet operation and eliminates the need for gasoline, making it a more environmentally friendly option. Moreover, the pressure washer features an automatic shut-off system that protects the motor from overheating, extending its lifespan.

Another notable characteristic of the WS2800 is its versatility. It includes multiple spray nozzles, allowing users to easily switch between different spray patterns to suit various cleaning applications. The quick-connect nozzle system enables rapid changes, so users can adapt to different surfaces without hassle. Whether users require a narrow, high-pressure jet for tough stains or a wide fan spray for rinsing surfaces, the WS2800 can accommodate any requirement.

The design of the Campbell Hausfeld WS2800 emphasizes portability and ease of maneuverability. It features a lightweight, compact frame that makes transportation a breeze. The integrated handle and durable wheels allow users to move the unit around their property effortlessly, while the built-in storage compartments provide space for organizing accessories such as nozzles and hoses.

Overall, the Campbell Hausfeld WS2800 pressure washer stands out for its perfect blend of power, efficiency, and user-friendly features.
