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 preheater 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 the fusible links (1) and (2).
Remove the engine side cover on the right bottom side of the
machine, open the fusible link case cover, and you see the fusi-
ble links (3) and (4).

REMARK
A fusible link refers to the large-sized fuse installed in the high
current flow part of the circuit.
It protects the electrical components and wiring from burning, in
the same way as an ordinary fuse.
