CHECKING THE ENGINE OIL LEVEL
For oil capacities, see “Specifications,” Section 1.5. For
engine oil recommendations, see Section 3.3.1. To
check the engine oil level, proceed as follows (Figures
3.2 and 3.3):
1. Start the generator by moving the AUTO/OFF/
MANUAL switch to the MANUAL position. Allow it to
run for a short while and then shut it down by moving
the switch to the OFF position.
2. Remove the dipstick and wipe it dry with a
clean cloth.
3. Install the dipstick; then, remove it again. The oil
level should be at the dipstick “Full” mark. If
necessary, add oil to the “Full” mark only. DO NOT
FILL ABOVE THE “FULL” MARK.
Never operate the engine with the oil level
below the “Add” mark on the dipstick. Doing
this could damage the engine.
4. Install the dipstick.
5. Reset the AUTO/OFF/MANUAL switch to its original
position.
NOTE:
If the generator is to operate continuously for several
days the oil level should be monitored frequently. A
low oil shutdown can occur (Section 2.7.1) causing
loss of generator power to emergency circuits.

CHANGING THE ENGINE OIL
3.3.1 ENGINE OIL RECOMMENDATIONS
Use oil of American Petroleum Institute (API) Service
Class SG, SH or SJ.
Use all season SAE 5W-30
Synthetic oil.
Organic break-in oil is required before
using synthetic oil.
NOTE:
The unit is supplied with organic “break-in” oil. See
the “Break-in Procedure,” Section 2.1, for the first
required oil change.
Any attempt to crank or start the engine before
it has been properly serviced with the
recommended oil may result in an engine
failure.
3.3.2 OIL CHANGE PROCEDURE
To change the oil, proceed as follows:
1. Run the engine until it is thoroughly warmed up then
shut OFF the engine.
2. Immediately after the engine shuts OFF, pull the oil
drain hose (Figure 3.4) free of its retaining clip.
Remove the cap from the hose and drain the oil into
a suitable container.
3. After the oil has drained, replace the cap onto the end
of the oil drain hose. Retain the hose in the clip.
4. Refill with the proper recommended oil (see Section
3.3.1). See Section 1.5.2 for oil capacities.
