MACHINE OPERATIONS AND CONTROLS CHECK ELECTRIC WIRINGS If the fuses frequently blow or if there are traces of short circuits on the electrical wiring, locate the cause immediately and carry out repairs, or contact your Komatsu Dealer for repairs.

Check that there is no damage to the fuse, that a fuse of the specified capacity is being used, that there are no signs of any disconnection, breakage, or short circuit in the electric wiring, check for any loose terminals, and tight- en any loose terminals that are found.
Be particularly careful to check the wiring for the battery, starting motor, and alternator. In addition, if any flammable material is accumulated around the battery, remove it.
