3.1CHECKING THE ENGINE OIL LEVEL
For oil capacities and requirements, see “Engine Oil Requirements,” Section 1.5.4 (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,
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
•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 (see Figure 3.1):
1. Run the engine until it is thoroughly warmed up (at least five minutes) then shut OFF the engine.
2.Immediately after the engine shuts OFF, pull the oil drain hose free of its retaining clip. Remove the cap from the hose and drain the oil into a suitable container. Loosening the oil fill cap will allow the crankcase to drain faster.
3.After the oil has drained, replace the cap onto the end of the oil drain hose. Retain the hose in the clip.
GO TO STEP 7 IF CHANGING OIL ONLY.
4.With the oil drained, remove the old oil filter by turning it counterclockwise.
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 wipe it dry with a clean,
8.Remove the oil fill cap on the rocker cover and slowly add the proper type and amount of rec- ommended oil (see Section 1.5.4, Page 6). Periodically use the dipstick to check the oil level and continue to fill the crankcase until the oil reaches the dipstick “Full” mark. DO NOT FILL ABOVE THE “FULL” MARK.
9.Install and tighten the oil fill cap and the dipstick before operating the engine.
10.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.
