Maintenance and Operation Procedures
The high voltage that is produced by an operating generator set can cause severe injury or death. Before performing any maintenance or repairs, ensure that the generator will not start.Place the engine control switch in the "OFF" position. Attach "DO NOT OPERATE" tags to all starting controls. Disconnect the batteries or disable the starting system. Lock out all switchgear and automatic transfer switches that are associated with the generator.
The recommended maintenance for the engine is listed in this Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section).For the recommended generator maintenance, see the Operation and Maintenance Manual for the generator.Maintenance and Repair
The maintenance that is recommended for Every Week can be performed by an authorized operator. The maintenance that is recommended for the subsequent maintenance intervals must be performed by an authorized service technician or by your Caterpillar dealer.Unless other instructions are provided, perform maintenance and repairs under the following conditions:
The engine is stopped.
The starting system is disabled.
The generator does not pose an electrical shock hazard.Operation
To ensure proper operation, the generator set must be exercised regularly. For instructions on operating the generator set, see the Operation and Maintenance Manual for the generator set control panel.For these operation procedures, follow the instructions that are provided in this Operation and Maintenance Manual, "Operation Section": starting the engine, engine operation and stopping the engine.Record Keeping
Maintain a record in order to document these items: gauge readings, maintenance that is performed, problems and repairs.Space Heaters
Moisture causes damage to generators and other electrical equipment. Make every effort to keep the generator set as dry as possible.Generators can operate without problems in humid environments. However, problems can occur when the generator is inactive. Moisture can condense on the windings. This can result in poor performance. Also, damage to the windings can occur.Use space heaters in order to help keep the windings dry. When the generator is not active, ensure that the space heaters are operating. When the generator is operating, turn OFF the space heaters.Service Hours and Fuel Consumption
