5. Maintenance 3-2018

NOTICE

Cummins highly recommends that any service or maintenance work be

performed by qualified technicians.

1. Before changing the oil, the generator set should be operated until the water

temperature is approximately 60 °C (140 ° F).

2. Make sure the generator set is shut down and disabled:

a. Press the generator set's "O" (Off) button to stop the generator set. Allow

the generator set to thoroughly cool to the touch.

b. If applicable, turn off and disconnect the battery charger from the AC

source before disconnecting the battery cables.

c. Disconnect the negative (–) cable from the battery and secure it from

contacting the battery terminals to prevent accidental starting.

3. Drain the oil. Place the end of the drain hose into an appropriate container.

NOTICE

Refer to local regulations to determine the appropriate container for

used oil.

4. Remove the oil filter, and clean the filter mounting surface on the engine block.

Remove the old gasket if it remains.

5. Make sure the gasket is in place on the new filter and apply a thin film of clean

oil to the gasket.

6. Install the new filter until the gasket just touches the block. Turn it an additional

1/2 to 3/4 turn. Do not over-tighten.

7. Remove the container used to collect oil when removing the oil filter.

8. Close the oil drain valve.

9. Add the appropriate amount of oil.

NOTICE

Too much oil can cause high oil consumption. Too little oil can cause

severe engine damage. Keep the oil level between the High and Low

marks.

10. Operate the engine at idle to inspect for leaks at the lubricating oil filter and the

drain plug.

11. Confirm that the correct oil level is in the pan:

a. Shut the generator set off and wait 5 minutes.

b. Check the engine oil level.

12. Check and repair any leaks identified.
