Section 3 – MaintenancePRIMEPACT 50 Recreational Vehicle Generator3.1 CHECKING THE ENGINE OIL LEVELFor oil capacities and requirements, see “Engine OilRequirements,” Section 1.5.4 (Page 6). Check theengine crankcase oil level at least every eight hours ofoperation, or before you use it. To check the engineoil 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, removeit again. The oil level should be at the dipstick“Full” mark.4. If necessary, remove the oil fill cap on the rockercover and slowly add oil until it reaches the dipstick“Full” mark. DO NOT FILL ABOVE THE“FULL” MARK.Never operate the engine with the oil level! below the “Add” mark on the dipstick. Doingthis could damage the engine.5. Install and tighten the oil fill cap and the dipstickbefore operating the engine.3.2 CHANGING THE ENGINE OILAND/OR OIL FILTER• Change the engine oil after the first 25 hours ofoperation (after the 25-hour break-in period, seeSection 2.10.1, Page 11). Thereafter, change theoil every 100 operating hours. Change the oil morefrequently if operating consistently under heavyload or at high ambient temperatures.• Change the engine oil filter after the first 25 hoursof operation, and every 100 operating hours thereafter.Figure 3.1 – Oil Maintenance FeaturesTo change the oil and/or oil filter, proceed asfollows (see Figure 3.1):1. Run the engine until it is thoroughly warmed up(at least five minutes) then shut OFFthe engine.2. Immediately after the engine shuts OFF, pull theoil drain hose free of its retaining clip. Removethe cap from the hose and drain the oil into asuitable container. Loosening the oil fill cap willallow the crankcase to drain faster.3. After the oil has drained, replace the cap onto theend of the oil drain hose. Retain the hose in the clip.4. With the oil drained, remove the old oil filter byturning it counterclockwise.5. Apply a light coating of clean engine oil to the gasketof the new filter.6. Screw the new filter on by hand until its gasketlightly contacts the oil filter adapter. Then, tightenthe 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 theoil level.8. Remove the oil fill cap on the rocker cover andslowly add the proper type and amount of recommendedoil (see Section 1.5.4, Page 6).Periodically use the dipstick to check the oil leveland continue to fill the crankcase until the oilreaches the dipstick “Full” mark. DO NOT FILLABOVE THE “FULL” MARK.9. Install and tighten the oil fill cap and the dipstickbefore operating the engine.10. Start the engine and check for leaks.NOTE:Check the oil level and fill to the “FULL” markafter checking for leaks. The filter will retain someoil.12 Generac ® Power Systems, Inc.
