Low oil pressure alert

If the oil pressure drops too low, the alert de-
vice will activate.

●

The engine speed will automatically de-
crease to about 2000 r/min. If equipped
with a low oil pressure-alert indicator, it will
light or blink.

●

The buzzer will sound (if equipped on the
tiller handle, remote control box, or main
switch panel).
