Repair and Diagnosis: Service Precautions
DRILLING AND WELDINGWhen holes must be drilled or punched in an inner body panel, verify depth of space to the outer body panel, electrical wiring, or other components. Damage to vehicle can result.
Do not weld exterior panels unless combustible material on the interior of vehicle is removed from the repair area. Fire or hazardous conditions can result.
Always have a fire extinguisher ready for use when welding.
