To prevent injury to the operator or damage to the
mower, never replace a fuse with a higher
amperage rating fuse.
Never bypass fuses. Fire damage may result.
For proper operation of the SLF530 mower, do
not insert a fuse in the F10 location.
Placing a fuse in the F10 location will select the
wrong program in the mower controller.
