SECTION II. TROUBLESHOOTING PROCEDURES
3-2
GENERAL. Troubleshooting at the operator level requires you to locate any trouble as quickly as
possible. Once trouble is located, repair or replace the part if you are authorized to do so or determine if a
higher category of maintenance is required. Repairs at the operator level are limited by tools, test equipment,
and replacement parts allocated to that level.
WARNING
Troubleshooting procedures may require that checks be made while the
engine is running. Use extreme care to prevent contact with high
temperature exhaust electrical or moving parts. Proper care must be taken
to provide efficient ventilation when running the engine indoors; exhaust
gases contain carbon monoxide which is odorless and a deadly poison.
Spilling diesel fuel on or about a hot engine may cause an explosion and
serious injury.
