TP-6804 2/1462 Section 5 Scheduled Maintenance
5.2 Lubrication System
See the service schedules in Section 5.1 for oil change
and oil filter replacement intervals. See the service
views in Section 1.8 for the oil drain, oil check, oil fill, 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 the engine 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 the oil level between the Add and Full marks on
the dipstick. Add 5W-30 or 10W-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.

5.2.3 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.
5.2.4 Oil Change Procedure
Note: Dispose of all waste materials (engine oil, fuel,
filter, etc.) in an environmentally safe manner.
Drain the oil while it is still warm.
1. Drain the oil.
a. Press the OFF button on the generator set
controller.
b. Disconnect the utility power to the generator
set.
c. Disconnect the generator set engine starting
battery, negative (--) lead first.
d. Remove the housing side panel.
e. Clean the area around the dipstick and oil fill

f. Remove the oil drain hose from its retaining
clip. Remove the cap from the oil drain hose
and lower the hose into an oil collection
container.
g. Open the oil drain valve on the engine.
h. Remove the dipstick and oil fill cap. Allow time
for the engine oil to drain completely.
i. Close the oil drain valve. Replace the cap on
the oil drain hose. Replace the oil drain hose in
its retaining clip.
j. Replace the dipstick.
2. Replace the oil filter.
a. Clean the area around the oil filter. Remove the
oil filter by rotating it counterclockwise with an
oil filter wrench.
b. Clean the gasket sealing surface of the oil filter
adapter.
c. Apply a light coat of clean oil to the rubber seal
of the new oil filter.
d. Install the new oil filter following the instructions
provided with the filter.
