If the generator set causes electrical interference with communications devices, move the
generator set and device farther apart or shut down the generator set while the device is
operating.
Exercise the generator set at least two hours every month if use is infrequent. Run it at
approximately 50 percent capacity. A single two-hour exercise period is better than several
shorter periods. Exercising a generator set drives off moisture, re-lubricates the engine,
replaces stale fuel, and removes oxides from electrical contacts. The result is better starting,
more reliable operation, and longer engine life.
Proper engine break-in is necessary for top performance.
1. Operate the generator set as it is intended to be operated. However, for the first 1-1/2
hours, if possible, run the generator set at 50 percent capacity, occasionally operating at
full power for brief periods. Avoid prolonged low-power operation during break-in.
2. Make sure the engine has oil of the proper viscosity for the ambient temperature. See
"RECOMMENDED ENGINE OIL."
3. Check the oil level twice a day or after every 4 hours of operation during the first 20 hours
of operation. Change the engine oil after the first 20 hours of operation.
If you are unable to exercise the generator set regularly, and it will not be in use for more than
120 days, the following storage procedure is recommended. Failure to provide out-of-service
protection can result in difficult starting, rough engine operation and reduced engine life.
