QUIETPACT 50 and 70 Recreational Vehicle Generators
2.8.7 OPERATION IN HIGH GRASS
OR BRUSH
Never operate the generator while the vehicle
is parked over high grass, weeds, brush,
leaves or any other combustible substance.
Such materials can ignite and burn from the
heat of the exhaust system. The generator
exhaust system becomes extremely hot dur-
ing operation and remains hot for a long time
after it has shut down.
3.1
CHECKING THE ENGINE OIL
LEVEL
Never operate the engine with the oil level
below the “Add” mark on the dipstick. Doing
this could damage the engine.
For oil capacities and requirements, see “Engine Oil
Requirements,” Section 1.6.2 (Page 6). Check the
engine crankcase oil level at least every eight hours of
operation, or before you use it. To check the engine
oil 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, remove
it again. The oil level should be at the dipstick
“Full” mark.
4. If necessary, remove the oil fill cap on the rocker
cover and slowly add oil until it reaches the dip-
stick “Full” mark. DO NOT FILL ABOVE THE
“FULL” MARK.
5. Install and tighten the oil fill cap and the dipstick
before operating the engine.
3.2
CHANGING 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
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. DO NOT FILL ABOVE THE
“FULL” MARK.
8. Install and tighten the dipstick before operating
the engine.
9. Start the engine and check for leaks.
