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 origi- nal position.

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, 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) 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 for oil capaci- ties.

4.4CHANGING THE OIL FILTER

Change the engine oil filter as follows:

1.With the oil drained, remove the old oil filter by turning it counterclockwise.

2.Apply a light coating of clean engine oil to the gasket of the new filter. See Section 1.5.1 for rec- ommended filter.

3.Screw the new filter on by hand until its gasket lightly contacts the oil filter adapter. Then, tighten the filter an additional 3/4 to one turn (Figure 4.4).

4.Refill with the proper recommended oil (see Section 4.3.1). See Section 1.5.2 for oil capaci- ties.

5.Start the engine and check for leaks.
