Disconnect and cap all fuel and vent lines. Purge fuel residue and fumes by steam cleaning. Purge air from fuel tank with CO2. e. FUEL TANKS 1) You must observe all safety precautions when working with fuel or fuel lines. WARNING Do not weld on plastic molding material parts. Welding on plastic molding material parts creates toxic fumes. Fumes are hazardous to your health and can result in death. f. PLASTIC MOLDING MATERIAL PARTS. The following is a list of plastic molding material parts and their location on the carrier: 1) Driver’s power plant compartment access panel. 2) Power plant rear compartment access panel. 3) Driver’s seat upholstered backrest. 4) Trim vane rear pod. 5) Trim vane front pod. 6) All armor. g. MIG WELDING METHOD. 1) MIG (Metal-Inert-Gas) welding. This process uses a DC power source, control panel, and a welding gun. The gun feeds a consumable bare electrode at a given rate into a molten pool beneath a blanket of inert gas. When an arc is struck, a molten pool forms at once. Move the welding gun along the joint line at a rate that shapes the right size bead. The covering inert gas keeps air from polluting the welding zone. No flux is needed. 0014 00-12
