32 TROUBLESHOOTING
7.1 INTRODUCTION
This section contains instructions for troubleshooting the equipment following a malfunction. Each issue or
problem is followed by a list of probable causes and suggested actions to be followed in order to eliminate
the cause.
The actions listed should be performed in the order listed, although the order may be varied if the need is
indicated by conditions under which the problem occurred. The action which can be performed in the least
amount of time and with the removal or disassembly of the fewest parts should be performed first.
7.2 UNPLANNED SHUTDOWN / WILL NOT START
POSSIbLE CAUSE ACTION
Low Fuel Fill the machine with fuel and retest.
Water or contamination in fuel filter Replace all fuel filters and drain the water from the fuel
tank(s).
Improper fan belt tension Adjust or replace the fan belt as needed.
Low battery voltage Check the voltage and recharge or replace as necessary.
If battery cables are loose, tighten cables.
If battery cables are dirty, clean thoroughly.
Clogged air filter Replace the air filter element.
Obstruction in radiator and/or oil cooler Remove any external obstructions and clean the coolers.
Faulty engine stop solenoid Check and replace if necessary.
Broken hoses or oil lines Repair/Replace any broken hoses or oil lines.
Loose or broken wires Repair/Replace any loose or broken wires.
Water temperature switch open Check the engine coolant level. Add as needed.
Clean the coolers.
Check the fan belt tension. Adjust or replace as needed.
Refer to Engine Manufacturer’s manual.
High compressor discharge air temperature Check compressor oil level. Add as needed.
Clean the coolers and pressure check.
Check the fan belt tension. Adjust or replace as needed.
Change compressor oil and oil filter element.
Clean oil cooler internally.
Verify correct operation of thermal by-pass valve;
Inspect and clean the thermal by-pass valve by
removing valve from by-pass housing. Sediment
particles can lodge in the valve-seating surface and
prevent from closing, allowing hot oil to pass directly to
the compressor without being cooled.
Engine oil pressure switch open Check engine oil. Add as needed.
Verify the engine oil pressure exceeds 12 psi with the
engine running.
If none of the above caused the shutdown, restart the engine and observe the engine oil pressure, engine
water temperature, and compressor discharge temperature and pressure gauges. If it is found that
low engine oil pressure or high engine water temperature is causing the shutdown, refer to the Engine
Manufacturer’s manual.
