OPERATING INSTRUCTIONS
NOTE
Some engines are equipped with
an engine starting motor protec-
tion feature.
If the starting mo-
tor is engaged for 30 or more sec-
onds, without the engine starting,
the starter will be locked out from
operating, allowing for proper cool-
ing of the starting motor. During
this time, the “Wait-to-Start” lamp
will flash for two minutes.
Once
the lamp discontinues flashing, the
starting motor will be allowed to
function.
CAUTION
The engine must have adequate oil
pressure within 15 seconds after
starting the engine. If the oil pres-
sure gauge does not register the
minimum pressure, or drops below
the minimum pressure, a red warn-
ing light in the gauge will come on,
a warning buzzer will sound, and
the “Stop Engine” lamp will come
on. This should be considered an
emergency. Operating the engine
in this condition may cause severe
engine damage. You should stop
the vehicle as safely as possible.
The vehicle must be serviced and
the problem corrected before driv-
ing again.
