Troubleshooting Chart
Symptom
Engine will not start from lower
or upper controls.
Engine will not start from
lower controls.
Possible Cause
Out of fuel. The engine will crank,
but will not start.
Engine is cold.
High engine temperature.
Low oil pressure.
Switches are set wrong. The engine
will not crank.
The start switch was left in the on
position for 30 seconds or longer
before turning it to start.
The main system circuit breaker on
the lower control panel has tripped.
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),
press and hold the preheat button
for five seconds before starting the
engine.
When the ambient temperature is
below 23°F (-5°C), press and hold
the preheat button 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.
Turn the battery disconnect switch
on and then at the lower controls:
• Turn the start switch off.
• Pull emergency stop button
outward.
• Place the controls switch in the
lower control position.
• Place the start switch in the on
position for 5 seconds and then
turn the switch to start.
Turn the start switch back to off,
then to start within 30 seconds.
Push the main system circuit break-
er button back in. If the button pops
back out, refer the problem to a
qualified service technician.
