Check Electrical Harnesses and Fuses --- every 50
Check the electrical harness and terminals of the batteries,
starter motor, and alternator for loose connection and/or short
circuit (broken shield). If any burned mark or an abnormal
smell is noticed on a harness, consult your nearest Hitachi
dealer.
Replace Fuse:
1. If any electrical equipment becomes inoperable, first
check the fuses in the fuse box located in the right consol
(behind the front control lever) in the operator's station.
2. One each spare fuse for respective fuse capacities is pro-
vided in the fuse box.
3. Finally, check slow blow fuses (1) (2) located on the left
side of the base machine.
