DANGER
• If the fuses are corroded, oxidized or not perfectly held in their seat, replace them only with fuses having
the same capacity; before changing a fuse, make sure that the ignition key is in position “O”.
• If there are signs of short circuit on the cables, find out the cause and repair them; always contact your
Komatsu Utility Dealer for the troubleshooting.
Make sure that there are no disconnected cables or signs of short circuit in the electrical system.
Make sure that all the cables are well tightened in the relevant terminals; tighten any loose cables.
In particular, check:
1. Battery
2. Starter
