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.
If the starting motor is not cranked when the starting switch is
turned to the START, there is probably a disconnection in fusi-
ble link (1) (2 places). Open the cover on the left side of the
machine and perform inspection and replacement.
REMARK
A fusible link refers to the large-sized fuse wiring installed in
the high current flow part of the circuit. It protects electrical
components and wiring from burning, in the same way as an
ordinary fuse.
TOOL BOX
Store the tools in it.
This is installed in the tool case at the left of the machine.
