Possible Cause
Out of fuel. The engine will crank,
but will not start.
Engine is cold.
High engine temperature.
Low oil pressure.
Dual fuel machines. The fuel switch
on the lower control panel is set
incorrectly. The engine cranks, but
will not start.
Switches are set wrong. The engine
will not crank.
Corrective Action
Add correct type of fuel. Try starting
the engine for 20 seconds and then
let the starter motor cool for 60 sec-
onds. Repeat as necessary.
When the ambient temperature
range is 50°F (10°C) to 23°F (-5°C),
let the engine preheat for five sec-
onds before starting the engine.
When the ambient temperature is
below 23°F (-5°C), let the engine
preheat for ten seconds before
starting the engine.
Let engine cool. Do not restart the
engine until the cause of overheat-
ing has been corrected.
Do not try to start the engine until
the cause of low oil pressure has
been corrected. The engine can be
restarted with low oil pressure, but it
will only run a few seconds before it
shuts off again.
• Place the fuel switch on the low-
er control panel in the proper
position for the fuel being used.
• Make certain there is fuel in the
fuel tank.
• If using LPG make certain that
the fuel shutoff valve is open.
• Try starting the engine for 20
seconds and then let the start-
er motor cool for 60 seconds.
Repeat as necessary.
Turn the battery disconnect switch
on and then at the lower controls:
