Information:
General
The objective of this information is to assist users in establishing a Preventive Maintenance Program for Standby Generator Sets or as an aid in evaluating their present programs.Standby Generator Sets may not be needed very often, but when they are, it is usually under emergency conditions. Maintenance of these standby units is very important. They must always be in excellent operating condition, ready to work under load at any time.Establishing a Preventive Maintenance Program will provide maximum availability of a standby generator set when needed, longer engine and generator life, and a minimum of expensive repairs.The recommended weekly maintenance checks can be performed by an operator. All yearly and three year maintenance should be performed by an authorized mechanic or your Caterpillar dealer.These guidelines are to be used with the information contained in the Operation and Maintenance Sections of this guide. The Operation and Maintenance sections of the guide will provide the necessary information on how to perform the checks and routine maintenance. Additional information can be obtained from the Generator and Engine Service Manuals, or contact your Caterpillar dealer for assistance.Inspection and Maintenance Agreements
Your Caterpillar dealer can establish an Inspection and Preventive Maintenance Program for your generator set to provide maximum reliability, increased engine and generator life, and minimize expensive repairs. Contact your Caterpillar dealer for details.Safety
Always make repairs with the engine stopped and the starting system disabled. When servicing the generator, make sure that switch gear and automatic transfer switches will not present a shock hazard. Lock them out on the generator being serviced.Record Keeping
Maintain a log or record keeping system to document all gauge readings, problems, repairs, and maintenance performed on the equipment.Space Heaters
Moisture is a natural enemy of generators and all electrical equipment. Every effort must be made to keep the generator as dry as possible. Space heaters should be operated inside the generator when it is not in use to maintain integrity of the generator windings.
Failure to comply with the following could result in personal injury or death.
* The Stop-Manual-Automatic (Auto Start/Stop) switch on the cranking panel must be at STOP position when performing maintenance or repair work on a standby generator set. This prevents the unit from starting if a power failure or voltage drop should occur while working on the unit. * To prevent personal injury due to accidental starting of the engine, disconnect the batteries or disable the starting system before doing maintenance or repair work.* Lock out all switch gear and automatic transfer switches associated with the generator while performing maintenance or repairs. Make sure no shock hazard exists.
