3.3 Lubrication System

See Section 3.2, Service Schedule, for oil change and
oil filter replacement intervals. See Section 1.5, Service
Views, for the oil drain, oil check, oil fill, and oil filter
locations.
3.3.1

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.
3.3.2

Oil Check

The generator set is shipped with oil. Before operating
the generator set, check the engine oil in the crankcase.
See Figure 3-1 for the dipstick location.
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. See Section 3.3.3, 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.

Engine Oil Recommendation

Use 5W-30 API (American Petroleum Institute) Service
Class SG, SH, or SJ synthetic oil. Synthetic oil oxidizes
TP-6515 10/07
and thickens less than other oils and leaves the engine
intake valves and pistons cleaner.

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. Place the generator set master switch in the
OFF position.
b. Disconnect the power to the battery charger.
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
cap.
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.
