| NOTICE |
|---|
|
If it is necessary to replace fuses frequently, an electrical problem may exist. Contact your Cat dealer. |
| NOTICE |
|---|
|
Always replace fuses with the same type and capacity fuse that was removed. Otherwise, electrical damage could result. |
Fuses protect the electrical system from damage that is caused by overloaded electrical circuits. Replace a fuse if the element separates. If the fuse of a particular electrical system requires frequent replacement, check the electrical circuit. Repair the electrical circuit, if necessary. Use the tool that is stored on the electrical panel in order to remove the fuses.
