Charge Battery

Use a battery charger to maintain a fully charged battery
when the generator set is used in a standby application.
The engine battery-charging alternator charges the
battery while the generator set is running.
Note: If the generator set is in a temporary prime power
application in which the generator set has periods
of inactivity, the controller circuitry may drain the
battery. If there is no power source for a battery
charger, place the controller in the prime power
mode, if equipped, or disconnect the battery from
the generator set.

3.10 Storage Procedure

Perform the following storage procedure before taking a
generator set out of service for three months or longer.
Follow the engine manufacturer's recommendations, if
available, for fuel system and internal engine

component storage.
F)

3.10.1 Lubricating System

Prepare the engine lubricating system for storage as
follows:
1. Run the generator set for a minimum of 30 minutes
to bring it to normal operating temperature.
2. Stop the generator set.

3. With the engine still warm, drain the oil from the
crankcase.

F)
4. Remove and replace the oil filter.
5. Refill the crankcase with oil suited to the climate.
6. Run the generator set for two minutes to distribute
the clean oil.
7. Stop the generator set.
8. Check the oil level and adjust, if needed.

3.10.2 Cooling System

Prepare the cooling system for storage as follows:
1. Check the coolant freeze protection using a
coolant tester.
2. Add or replace coolant as necessary to ensure
adequate freezing protection. Use the guidelines
1-787
included in the engine operation manual.
3. Run the generator set for 30 minutes to redistribute
added coolant.

3.10.3 Fuel System

Prepare the fuel system for storage as follows:
Diesel-Fueled Engines
1. Fill the fuel tank with #2 diesel fuel.
2. Condition the fuel system with compatible
additives to control microbial growth.
3. Change the fuel filter/separator and bleed the fuel
system. See the engine owner's manual.
