4.2CHECKING 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.

4.3CHANGING 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.

5. Reset the Auto/Off/Manual switch to its original	‹ 4.3.2 OIL CHANGE PROCEDURE
position.
	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.
