2.8.4 OVERVOLTAGE
PROTECTION
A solid-state voltage regulator (Figure 2.4) controls the generator’s
AC output voltage. This regulator supplies an excitation current to
the rotor. By regulating the rotor’s excitation current, the strength
of its magnetic field is regulated and, in turn, the voltage delivered
to connected electrical loads is controlled. When the AC frequency
is 60 Hertz, voltage is regulated at 125 to 120 volts.

2.8.5 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 mate-
rials 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.

CHECKING THE ENGINE OIL
LEVEL
For oil capacities and requirements, see the “Engine Oil
Requirements” section. Check the engine crankcase oil level at
least every eight hours of operation, or before it is used. 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 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. Doing this
could damage the engine.
5. Install and tighten the oil fill cap and the dipstick before oper-
ating the engine.

CHANGING THE ENGINE OIL
AND/OR OIL FILTER
Oil Change Intervals – see Section “RV Generator Service
Interval”.
To change the oil and 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 round
access grommet from underneath the front of the generator.
Place a suitable container underneath to catch all the drain
oil.
3. Use the 0G4818 tool (supplied with the generator) to turn the
old filter counter-clockwise and remove. Let oil drain into the
container located directly below.
4. Locate the oil drain hose inside and pull the yellow drain plug
out of the access hole (Figure 3.1).
5. Turn the yellow cap counter-clockwise to remove and finish
draining the old oil.
6. After the oil has been drained, replace the oil drain plug by
tightening it clockwise and return.
7. Clean off the oil filter bracket and any old oil that may have
spilled while draining.
8. Apply a light coating of clean engine oil the gasket of the new
oil filter (Figure 3.2).
9. Screw the new oil filter on by hand until its gasket lightly con-
tacts the oil filter adapter. Then, tighten the filter an additional
¾ to one turn. Replace and secure the round access grom-
met.
