TROUBLESHOOTING
6.1
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.
6.2
UNPLANNED SHUTDOWN
POSSIBLE CAUSE
ACTION
Engine fault codes present
Machine not out of warm-up mode; allow machine to
complete warm-up.
High compressor discharge temperature
Check compressor oil level; add as needed.
Clean the coolers and pressure check.
Check the fan belt tension. Adjust or replace as needed.
Verify correct operation of thermal by-pass valve.
Change compressor oil and oil filter element.
Clean oil cooler internally.
Inspect and clean the thermal by-pass valve by
removing valve from bypass 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.
Water or contamination in fuel filter
Replace all fuel filters and drain the water from the fuel
tank(s).
Low engine coolant and/or high engine coolant
temperature
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, located at
www.kohlerpower.com.
Low engine oil pressure fault code
Check engine oil; add as needed.
Verify the engine oil pressure exceeds engine
manufacturer’s spec with the engine running.
Obstruction in radiator and/or oil cooler
Remove any external obstructions and clean the coolers.
Improper fan belt tension
Replace the fan belt or tensioner as needed.
Broken hoses or oil lines
Repair/Replace any broken hoses or oil lines.
Loose or broken wires
Repair/Replace any loose or broken wires.
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. 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, located at www.kohlerpower.com.
6.3
DISCHARGE PRESSURE IS TOO LOW
POSSIBLE CAUSE
ACTION
Start/Run valve in the START position
Move the Start/Run valve to the RUN position and retest.
Too much air demand
Add additional compressor to handle the demand or
decrease the air demand.
Service valve open
Close service valve and retest.
Regulator valve faulty or mis-adjusted
Properly adjust the regulator.
Rebuild/replace the regulator valve if necessary.
Service line leaks
Repair any leaks found and retest.
Compressor inlet air filter restricted
Replace the air filter and retest.
