See Section 2.1, Service Schedule, for oil change and
oil filter replacement intervals.

filter locations.
2.2.1

Low Oil Pressure Shutdown

The low oil pressure (LOP) shutdown feature protects
the engine against internal damage if the oil pressure
drops below a minimum pressure because of oil pump
failure or other malfunction.
Note: The LOP shutdown feature does not protect
against damage caused by operating when the
oil level is low; it is not a low oil level shutdown.
Check the oil level regularly, and add oil as
needed.
2.2.2

Oil Check

The generator set is shipped with oil. Before operating
the generator set, check the engine oil in the
crankcase. See Figure 2-2.
Maintain the oil level at or near, not over, the full mark
on the dipstick. Add 5W-30 synthetic oil when the oil
level is low.
Check the oil level before each use. For extended
operation, check the oil level every 8 hours. Do not
check the oil level when the generator set is running.
Shut down the generator set and wait several minutes
before checking the oil.

Engine Oil Recommendation

Use 5W-30 API (American Petroleum Institute)
Service Class SG, SH, or SJ synthetic oil. Synthetic oil
oxidizes and thickens less than other oils and leaves
the engine intake valves and pistons cleaner.
