SECTION 1 − SAFETY PRECAUTIONS - READ BEFORE USING pom_2013−09 Protect yourself and others from injury — read, follow, and save these important safety precautions and operating instructions. 1-1. Symbol Usage DANGER! − Indicates a hazardous situation which, if not avoided, will result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text. Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
ELECTRIC SHOCK can kill. FUMES AND GASES can be hazardous. SIGNIFICANT DC VOLTAGE exists in inverter power sources AFTER the removal of input power. Cutting produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Turn Off unit, disconnect input power, check voltage on input capacitors, and be sure it is near zero (0) volts before touching any parts.
1-3. Additional Symbols For Installation, Operation, And Maintenance HOT PARTS can burn. BATTERY EXPLOSION can injure. Do not touch hot parts bare handed. Allow cooling period before working on equipment. To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. Do not use plasma cutter to charge batteries or jump start vehicles unless it has a battery charging feature designed for this purpose. FALLING EQUIPMENT can injure.
1-4. California Proposition 65 Warnings Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Section 25249.5 et seq.) This product contains chemicals, including lead, known to the state of California to cause cancer, birth defects, or other reproductive harm.

SECTION 2 − CONSIGNES DE SÉCURITÉ − LIRE AVANT UTILISATION pom_2013−09fre Pour écarter les risques de blessure pour vous−même et pour autrui — lire, appliquer et ranger en lieu sûr ces consignes relatives aux précautions de sécurité et au mode opératoire. 2-1. Signification des symboles DANGER! − Indique une situation dangereuse qui si on l’évite pas peut donner la mort ou des blessures graves. Les dangers possibles sont montrés par les symboles joints ou sont expliqués dans le texte.
Coupez l’alimentation d’entrée avant d’installer l’appareil ou d’effectuer l’entretien. Verrouillez ou étiquetez la sortie d’alimentation selon la norme OSHA 29 CFR 1910.147 (reportez−vous aux Principales normes de sécurité). Installer le poste correctement et le mettre à la terre convenablement selon les consignes du manuel de l’opérateur et les normes nationales, départementales et locales.
Si vous êtes à l’intérieur au moment du coupage, ventilez la pièce ou ayez recours à une ventilation aspirante installée près de l’arc pour évacuer les vapeurs et les gaz. Pour déterminer la bonne ventilation, il est recommandé de procéder à un prélèvement pour la composition et la quantité de fumées et de gaz auxquels est exposé le personnel. Si la ventilation est médiocre, utilisez un respirateur anti−vapeurs approuvé.
LIRE LES INSTRUCTIONS. Lire et appliquer les instructions sur les étiquettes et le Mode d’emploi avant l’installation, l’utilisation ou l’entretien de l’appareil. Lire les informations de sécurité au début du manuel et dans chaque section. N’utiliser que les pièces de rechange recommandées par le constructeur. Effectuer l’entretien en respectant les manuels d’utilisation, les normes industrielles et les codes nationaux, d’état et locaux.
2-4. Proposition californienne 65 Avertissements Les équipements de soudage et de coupage produisent des fumées et des gaz qui contiennent des produits chimiques dont l’État de Californie reconnaît qu’ils provoquent des malformations congénitales et, dans certains cas, des cancers.
