Engine control system
The oil level-alert indicator will light or
●
blink.
The buzzer will sound (if equipped on the
●
tiller handle, remote control box, or main
switch panel).
If the alert system has been activated, stop
the engine and check for the cause.
TIP:
The alert for oil filter clogging is similar to the
alerts for low oil level and overheating. To
32
make troubleshooting easier, check for en-
gine overheating first, then oil level, and fi-
nally oil filter clogging.
