3.3 Lubrication System
See Section 3.2, Service Schedule, for oil change and
oil filter replacement intervals. See Section 1.5 for the
oil drain, oil check, oil fill, and oil filter locations.
For extended operation, check the oil level every 8
hours. Maintain the oil level at or near, not over, the full
mark on the dipstick.
3.3.1
Low Oil Pressure Shutdown
The low oil pressure shutdown feature protects the
engine against internal damage if the oil pressure drops
below 24.1 kPa ±13.8 kPa (3.5 psi ±1.5 psi) because of
oil pump failure or other malfunction. The shutdown
feature does not protect against damage caused by
operating with the oil level below the safe range; 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 a
new generator set, check the engine oil in the
crankcase.
See
Section 1.5,
Components. Verify that the oil level is at the F mark on
the dipstick. Add oil that has a viscosity appropriate for
the
climate.
See
Recommendation.
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 level.
3.3.3
Engine Oil Recommendation
Use 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. Select the viscosity
based on the air temperature at the time of operation.
See Figure 3-1.
