STUD-TAPERLOCK 5M1932 - Caterpillar

Disabling a Generator for Maintenance
There are two conditions when maintenance checks may have to be performed on the unit:
When the unit is in standby mode (automatic) and NOT running. To disable the unit from starting in this condition, to perform maintenance checks or service.
When the unit is running and providing power to the load. To shut down the unit safely, without damaging loads or the generator, follow the steps for shutting down a unit while in operation. Before shutting down an operating unit for maintenance, always make sure that personnel are warned that the power will be shut down temporarily, so that equipment that might be damaged can be properly turned off or placed in standby.To Disable the Generator From Starting
To prevent injury, BEFORE performing any maintenance, disable the generator set from starting and/or connecting to the load:
Set the control panel to the STOP.
Turn off power to the battery charger (remove battery charger 30A inline fuse).
Disconnect the positive battery cable.Note: The battery charger must be turned off "BEFORE" disconnecting the battery cable to prevent an over- current condition from burning out sensitive control panel components and circuits.Note: Following any maintenance, reverse these steps to insure the unit is returned to standby setup for normal operation.Shutdown and Restart an Operating Generator
If the unit is operating and required checks must be performed:
Ensure that power to the load can be interrupted (warn any equipment users that there will be a temporary power disruption). There may be other procedures that must be done before shutting down a unit, depending on application.
Open the generator Main Line Circuit Breaker (MLCB).
Allow the unit to cool down (running at no-load) for approximately 5 minutes to prevent damage to critical engine components.
Set the control panel to the STOP. There may be safety tag-outs or lockouts required at this point, depending on application.
Perform the necessary maintenance checks or tasks (based on the hourly requirements).
When all checks have been completed and any discrepancies corrected, set the control panel to the STOP.
When the generator is running, and all engine/generator parameters (voltage, frequency, coolant temp, oil pres- sure, etc.) have been verified as correct, close the generator Main Line Circuit Breaker (MLCB). The unit will accept and carry the load.
Make a last visual inspection of the generator set to make sure it is operating properly.Maintenance Tasks
Visually Inspect Unit
Perform a visual inspection of the unit periodically. If problems are found contact your local authorized service dealer. Look for the following:
Any debris, trash, grass or weed growth, which would obstruct the flow of cooling air into and out of the unit ventilation louvers.
Visually inspect hoses and hose connections for signs of leakage. This includes all coolant hoses, fuel hoses, exhaust system connections, intake system connections, etc. Also look at the engine block for signs of fluid leakage.
Visually inspect the engine accessory drive belts for evidence of obvious wear, fraying or deterioration, and obvious looseness. A "squealing" sound heard during starting and running could indicate a loose belt.Check Engine Fluids
The following checks can be
