OM2210 10/11 Safety - Section 22 Warnings and Cautions Page 22-5 A warning decal is located on the rear compartment in the operator cab. Use caution when working around or in this compartment. Electrical potential may be present even when the battery disconnect has been switched to OFF. Attached to the exterior of the battery compartment is a danger plate. This plate stresses the prevention of sparks near the battery. When another battery or 24VDC power source is used for auxiliary power, all switches must be OFF prior to connecting. Maintain correct polarity: connect the positive (+) posts together and then connect the negative (-) lead of the auxiliary power cable to a good frame ground.
Do not connect to the negative posts of the truck batteries. Do not connect near the battery box. These precau- tions minimize the danger of sparks near the batter- ies. Sulfuric acid is corrosive, toxic and explosive. Use safety goggles, rubber gloves and a rubber apron when working near batteries. If battery electrolyte is splashed into the eyes or is ingested, get the proper medical attention, immedi- ately. A caution plate is located on the side of the battery box. These instructions must be followed to avoid damage to electronic components when welding on the truck.
