The generator set must always be in excellent operating condition.
The generator set must be ready to work under load at any time.Establishing a Preventive Maintenance Program will provide these benefits:
Maximum availability of the standby generator set
Longer service life for the generator set
Minimum of expensive repairsYour Caterpillar dealer can help you to establish an effective Preventive Maintenance Program for your generator set. Consult your Caterpillar dealer for details.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.

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.
