Information relating to maintenance procedures is included in this engine guide. Further information is available in the Service Manual, or consult your Caterpillar dealer.Standby Generators
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. It is recommended that the following Preventive Maintenance Program be established.
The stop-manual-automatic switch on the cranking panel must be set 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. Failure to comply could result in personal injury or death.
Make any necessary repairs with the engine stopped and the starting system disabled.Maintain a log or a 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 the integrity of the generator windings.
