CHECKING THE ENGINE
OIL LEVEL
For oil capacities, see “Specifications,” Section 1.5
(Page 6). For engine oil recommendations, see
Section 4.3.1. To check the engine oil level, proceed
as follows (Figures 4.2 and 4.3):
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 nec-
essary, 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.

CHANGING THE ENGINE OIL
4.3.1 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 “break-in” oil. See the
“Break-in Procedure,” Section 3.1 (Page 14), for
the first required oil change.
Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
4.3.2 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 4.4 on page 18) 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 4.3.1). See Section 1.5.2 (Page 6) for oil
capacities.
