FUSIBLE LINK
NOTICE
When replacing the fusible link, be sure to turn the starting switch to OFF position and, after confirming
that the system operating lamp is not lit, set the battery disconnect switch key to OFF position.
When the starting switch is turned to START position, if the starting motor does not operate, any of the electrical
component in the operator's cab does not work, or the pre-heater does not work, a fusible link built in the wiring
harness is suspected to be disconnected. Check and replace the fusible link.
Open the hydraulic tank inspection cover on the left side of the
machine and then open the fusible link case cover, and you
see fusible links (1) and (2).
Remove the engine side cover on the right side of the machine
and then open the fusible link case cover, and you see fusible
links (3) and (4).
