See the service schedules in Section 5.1 for oil change
and oil filter replacement intervals. See the service
views inSection 1.9 for theoil drain,oil check, oilfill, and
oil filter locations.
5.2.1 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.
5.2.2 Oil Check
The generator set is shipped with oil. Before operating
the generator set, check theengine oil in the crankcase.
To check the oil level, shut down the generator set and
wait several minutes. Remove the dipstick and wipe the
end clean, reinsert, and remove. See Figure 5-1.
Maintain theoil level betweenthe Addand Full markson
the dipstick. Add5W-30 synthetic oilwhen the oillevel is

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.

5.2.3 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.
