3.2CHANGING THE ENGINE OIL

AND/OR OIL FILTER

•Change the engine oil after the first 25 hours of operation. 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 fol- lows (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.

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 gasket of the new filter.

6.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.

7.Remove the dipstick and wipe it dry with a clean, lint-free cloth. This will be used later to check the oil level.

8.Remove the oil fill cap on the rocker cover and slowly add the proper type and amount of recommended oil (see section "Engine Oil Requirements"). Periodically use the dipstick to check the oil level and continue to fill the crank- case 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.

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 3.2):

1.Turn the two screws counterclockwise to loosen.

2.Remove the cover, foam precleaner and paper filter.

3.Remove the foam precleaner from the cover.

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