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. D 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. D Do not touch hot parts bare handed. D Allow cooling period before working on equipment. D To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. D 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.
