NOTICE
Before replacing a fuse, be sure to turn off the starting switch.
The fuse holder is at the rear right of the operator's seat.
The fuses protect the electrical equipment and wiring from
burning out.
If the fuse becomes corroded, or white powder can be seen, or
the fuse is loose in the fuse holder, replace the fuse.
Replace the fuse with another of the same capacity.
