TP-6805 8/1522 Section 2 Scheduled Maintenance
2.2 Lubrication System
See Section 2.1, Service Schedule, for oil change and
oil filter replacement intervals. See Section 1.7, Service
View, for the oil drain, oil check, oil fill, and oil 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 for the dipstick location.
Maintain the oil level at or near, not over, the full mark on
the dipstick. Add 5W-30 or 10W-30 synthetic oil when
the oil level is low. See Section 2.2.3, Engine Oil
Recommendation.
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.

2.2.3 Engine Oil Recommendation
Use 5W-30 or 10W-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.
