4.2.2 Low Oil Level Switch (26RCA)
The low oil level switch protects the engine against internal damage if the oil pressure drops below a minimum level. The engine
shuts down and a fault message is displayed on the controller if the oil level is too low. See the Faults section for instructions if
the generator set shuts down on a fault.
Check the oil level regularly and add oil as needed.
4.2.3 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 54. 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.
Note:
The 26RCA is available with two types of oil, standard and premium. Do not mix oil types when adding oil.
Check the oil level before each use. For extended operation, check the oil level periodically as shown in the maintenance
schedule for your model. 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.

4.2.4 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.
4.2.5 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 end panels from the enclosure by lifting the panels up and out. Then lift off the service-side panel
to access the oil drain valve and hose.
e. Clean the area around the dipstick and oil fill cap.
