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 2.8.5, 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.

Figure 3.1 — Oil Dipstick/Fill Tube and

Location of Oil Drain Plug

Oil Dipstick

9.Start the engine and check for leaks.

Figure 3.2 — Engine Oil Filter

NOTE:

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

Oil Drain Hose

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 1.8 liters or 1.9 quarts with oil filter change. DO NOT FILL ABOVE THE “FULL” MARK.

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

3.3MAINTAINING THE ENGINE AIR CLEANER

3.3.1 CLEANING THE FOAM PRECLEANER

Clean and re-oil the foam precleaner every three months or every 25 hours of operation, whichever occurs first. Service the foam precleaner more fre- quently if operating the generator in extremely dusty or dirty conditions. Use the following procedure (Figure 3.3):

1.Turn the knob counterclockwise to loosen.

2.Remove the cover, foam precleaner and paper fil- ter.

3.Remove the foam precleaner from the cover.

4.Wash the foam precleaner in liquid detergent and water.

5.Wrap the foam precleaner in a clean cloth and gently squeeze it dry.

6.Saturate the foam precleaner in clean engine oil. Gently squeeze it in a clean cloth to remove excess oil and to distribute oil (DO NOT TWIST).

7.Install the foam precleaner into the cover, fol- lowed by the paper filter. Tabs at edges of paper filter must lock into slots on cover.

8.Install the cover, foam precleaner and paper filter.

9.Replace knob to retain the filter in place.
