Troubleshooting Chart
Symptom
Engine will not start from lower
or upper controls.
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.
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.
Cummins or GM 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.
• Place the fuel switch on the
lower control panel in the prop-
er position for the fuel being
used.
• Make certain there is fuel in the
fuel tank.
