Section 3 – Maintenance

QUIETPACT 40G Recreational Vehicle Generator

•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 cover free of the base. Remove the plug from the tube with a 5/16” allen wrench 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 plug onto the end of the oil drain tube. Retain the cover in the base.

4.With the oil drained, remove the old oil filter by turning it counterclockwise. Place a towel under- neath to catch excess oil.

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

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, lint-free cloth. This will be used later to check the oil level.

8.Remove the oil fill cap on the oil fill tube 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.

7.Install the foam precleaner into the cover, fol- lowed by the paper filter.

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

9.Tighten the two screws to retain the filter in place.

◆3.3.2 CLEANING OR REPLACING THE PAPER FILTER

Once each year or every 100 hours of operation (whichever comes first), clean or replace the paper filter. The new replacement filter must be flame retar- dant. Service the paper filter more frequently if oper- ating the generator in extremely dusty or dirty condi- tions. Use the following procedure (Figure 3.2):

1.Follow steps 1-3 in Section 3.3.1; service the foam precleaner if necessary.

2.Remove the paper filter.

3.Clean the air filter by tapping it gently on a solid surface. If the filter is too dirty, replace it with a new one. Dispose of the old filter properly.

4.Clean the air cleaner cover then reassemble following steps 7-9 in Section 3.3.1.

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.
