Generac NP-50G Recreational Vehicle Generator
This section includes information about simple maintenance
which includes the following tasks.
• Checking engine oil level.
• Changing engine oil.
• Changing oil filter.
• Changing the air cleaner.
• Cleaning the air intake screen.
• Cleaning spark plug.
CHECKING ENGINE OIL LEVEL
Check engine crankcase oil level at least every eight hours of
operation, or before you use it.
Be sure the generator is as level as possible.
• Remove OIL DIPSTICK (Figure 8) and wipe it dry with
clean, lint-free cloth.
• Install and tighten oil dipstick then remove again.
• Oil level should be at the dipstick “FULL" mark. If necessary,
add oil to the “FULL” mark only. DO NOT FILL ABOVE THE
“FULL” MARK.
• Install and tighten oil dipstick before operating the engine.
NOTE: See “Engine Oil Requirements” on Page 13 for rec­
ommended oils.

CHANGE ENGINE OIL
Change engine oil after the first 25 hours of operation (after
the 25-hour break-in period. Page 11). Thereafter, change oil
every 50 operating hours. Change oil more frequently if oper­
ating consistently under heavy load or at high ambient
temperatures. To change oil, proceed as follows:
• Run engine for at least 5 minutes, then shut down.
With engine still warm, remove oil drain cap from oil drain
hose (Rgure 9). Drain oil completely into a suitable container.

• Remove oil dipstick and fill crankcase with the recom­
mended oil (see Page 13). The engine crankcase can hold
about 1.4 liters. DO NOT FILL ABOVE “FULL” MARK.
• Install and tighten dipstick before operating engine.
CHANGE OIL FILTER
Change engine oil filter after the first 25 hours of operation,
every 100 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 10).
• Coat gasket of new filter with engine oil.
• Turn new filter clockwise until its gasket contacts lightly with
the filter adapter. Then tighten with an additional 3/4 to one
turn by hand.
• Run engine and check for leaks.
NOTE:
Check oil level and fill to full mark after checking for
leaks. Filter will retain some oil.
