Troubleshooting Chart
Symptom

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 master 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 wiring box has tripped. The en-
gine will not crank.
Corrective Action
Add correct type of fuel. Try start-
ing the engine for 20 seconds and
then let the starter motor cool for
60 seconds. Repeat as necessary.
Cummins engine – plug the block
heater into a 125 Volt AC, 600 watt
source eight hours before starting
the engine.
Deutz engine – hold the manifold
heater switch on for about a minute
before starting the engine. Hold the
switch on until the engine starts.
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 master start switch off.
• Place the emergency stop
switch in the on position.
• Place the controls switch in the
ground position.
• Place the master 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
breaker button back in. If the button
pops back out, refer the problem to
a qualified service technician.
