QUIETPACP* 750 Recreational Vehicle Generator
MAINTENANCE
# 2.8.4 OPERATION IN HIGH GRASS
_______ OR BRUSH__________________________
Never operate the generator while the vehicle is
parked over high grass, weeds, brush, leaves, or
other
combustible substance. Such materials can
ignite and burn from the heat of the exhaust system.
The generator exhaust system becomes extremely hot
during operation and remains hot for a long time
after it has shut down.
2.8.5 EFFEaS OF MOISTURE AND DIRT
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and mois­
ture to accumulate on generator windings will have
an adverse effect on the insulation resistance of those
windings.
When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This reduces insu­
lation resistance and will eventually cause problems.
Dirt will make the problem worse, since it tends to
hold moisture in contact with windings. Salt (as from
sea air) will also worsen the problem, since it tends
to absorb moisture from the air. Salt and moisture,
when combined, form a good electrical conductor.
3.1 CHECKING THE ENGINE OIL
LEVEL
After the 25-hour break-in period, check the engine
crankcase oil level every eight hours of operation, or
at least once daily, before using the generator. For oil
capacities
and requirements, see “Engine Oil
Requirements,” Section 1.5.3 (Page 6). To check the
engine oil level, proceed as follows (see Figure 3.1):

Be sure the generator is as leveled as possible.
Remove the dipstick, and wipe it dry with a clean,
lint-free cloth.
Install the dipstick, and fully seat the T-handle;
then, remove it again. The oil level should be at
the dipstick “Full” mark.
If necessary, remove the oil fill plug and slowly
add oil until it reaches the dipstick “FULU mark.
DO NOT FILL ABOVE THE “FULL’ MARK.
------- ik CAUTION Mk ----------------
A Never operate the engine with the oil level
below the "ADD" mark on the dipstick. Doing
this could damage the engine.
5. Install the oil-fill plug and the dipstick before
operating the engine.

3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
Change the engine oil and oil filter after the first 25
hours of operation (after the 25-hour break-in peri­
od, see Section 2.8.1, Page 10). See the “Service
Schedule,” Section 3.13 (Page 16), for subsequent oil
and filter changes. Change the oil more frequently, if
operating consistently under heavy load or at high
ambient temperatures.
To change the oil and/or oil filter, proceed as
follows (see Figure 3.1):
Run the engine until it is thoroughly warmed up
(for at least five minutes) then shut OFF
the engine.
Immediately after the engine shuts OFF, remove
the front service door, located beneath the unit,
by retracting the two latches and pivoting the
door downward.
Remove the air filter (see Section 3.3).
Remove the oil-drain plug and drain the oil into a
suitable container. Removing the oil-fill plug will
allow the crankcase to drain faster.
After the oil has drained, replace the oil-drain
plug.
Go to step 9 if changing oil only.
With the oil drained, remove the old oil filter by
turning it counterclockwise.
Apply a light coating of clean engine oil to the gas­
ket of the new filter.
Screw the new filter on by hand, until its gasket
hghtly contacts the oil filter adapter. Then, tight­
en the filter an additional 3/4 to one turn.
