3.1CHECKING THE ENGINE OIL

LEVEL

For oil capacities and requirements, see “Engine Oil Requirements,” Section 1.6.2 (Page 6). Check the engine crankcase oil level at least every eight hours of operation, or before you use it. To check the engine oil level, proceed as follows (see Figure 3.1):

1.Be sure the generator is as level as possible.

2.Remove the dipstick and wipe it dry with a clean, lint-free cloth.

3.Install and tighten the dipstick cap; then, remove it again. The oil level should be at the dipstick “Full” mark.

4.If necessary, remove the oil fill cap on the rocker cover and slowly add oil until it reaches the dip- stick “Full” mark. 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.

5.Install and tighten the oil fill cap and the dipstick before operating the engine.

3.2CHANGING THE ENGINE OIL

AND/OR OIL FILTER

•Change the engine oil after the first 25 hours of operation (after the 25-hour break-in period, see Section 2.9.1, Page 10). Thereafter, change the oil every 100 operating hours. Change the oil more frequently if operating consistently under heavy load or at high ambient temperatures.

•Change the engine oil filter after the first 25 hours of operation, and every 100 operating hours there- after.

To change the oil and/or oil filter, proceed as follows:

1. Run the engine until it is thoroughly warmed up (at least five minutes) then shut OFF the engine.

2.With the engine still warm from running, remove the oil drain plug (Figure 3.1). Drain the oil into a suitable container.

3.After the oil has drained, replace the oil drain plug. (If only changing the oil, go to step 7.)

4.With the oil drained, remove the old oil filter by turning it counterclockwise (Figure 3.2).

5.Apply a light coating of clean engine oil to the gas- ket of the new filter.

6.Screw the new filter on by hand until its gasket lightly contacts the oil filter adapter. Then, tight- en the filter an additional 3/4 to one turn.

7.Remove the dipstick and fill crankcase with the proper type and amount of recommended oil (see Section 1.6.2, Page 6). The engine crankcase can hold about 1.4 liters. DO NOT FILL ABOVE THE “FULL” MARK.

8.Install and tighten the dipstick before operating the engine.

9.Start the engine and check for leaks.

NOTE:

Check the oil level and fill to the “FULL” mark after checking for leaks. The filter will retain some oil.
