Recreational Vehicle Generator
The voltage regulator also incorporates a “voltage surge pro-
tection circuit.” This circuit prevents troublesome surges in the
generator AC output voltage. Voltage surge is a common cause
of damage to electronic equipment.
25-HOUR BREAK IN PERIOD
The first 25 hours of operation is the break-in period for the
generator. Properly breaking in the generator is essential to
minimize fuel consumption and provide maximum engine per-
formance. During this 25-hour break in period, follow this
procedure:
• Run the unit at varying electrical loads, to help seat engine
piston rings properly.
• For the 75-hour operation following the break in period,
avoid light electrical loads. Load the generator at 50% (or
more) of its rated wattage capacity. Repeated light loads
during these 75 hours can cause improper seating of engine
piston rings, resulting in blowby and high oil consumption.
• Check engine oil level frequently. Add oil if needed. It is
normal for the generator engine to consume more oil than
is normal until the piston rings have properly seated.
• After operating the unit for 25 hours, complete the tasks rec-
ommended under “25-Hour Check Up.”
25-HOUR CHECK UP
After the 25-hour break-in period, contact an authorized ser-
vice facility for the following maintenance. The vehicle owner
is responsible for any charges:
• Change engine crankcase oil and oil filter.
Check oil level.
• Inspect cooling and ventilation openings.
Check engine carburetor.
• Check engine ignition system.
• Inspect entire electrical system.
• Inspect the engine exhaust system.
OPERATION IN HIGH GRASS
OR BRUSH
WARNING: NEVER OPERATE THE GENERATOR
WHILE THE VEHICLE IS PARKED IN HIGH GRASS,
WEEDS, BRUSH OR LEAVES. SUCH MATERIALS
CAN IGNITE AND BURN FROM THE HEAT OF THE
EXHAUST SYSTEM. THE GENERATOR EXHAUST
BECOMES EXTREMELY HOT DURING OPERATION
AND REMAINS HOT FOR A LONG TIME AFTER IT
HAS SHUT DOWN.
ATTENTION REQUIRED AFTER SUB-
MERSION
If the recreational vehicle generator has been submerged in
water, it must NOT be started or operated. Following any sub-
mersion in water, have an authorized Generac Service Facility
thoroughly clean and dry the generator.
OPERATING PRECAUTIONS
Never operate the generator set while the vehicle is parked
over dry leaves, dry grass or any other combustible substance.
The generator’s exhaust system becomes extremely hot and
can cause fire if it is too close to combustible materials.
The generator’s exhaust system gives off DEADLY carbon
monoxide gas. this dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness and even death.
never operate the generator set with the vehicle inside any
garage or enclosed area. Never operate the generator if it has
a leaky exhaust system. Close windows in the vicinity of the
generator exhaust outlet and take any other steps to prevent
exhaust gases from entering rooms or areas occupied by
people or animals.
EFFECTS 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 moisture to accumulate on
generator windings will have an adverse effect on the insula-
tion 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 causes a reduced insulation resistance and
will eventually cause problems. Dirt will make the problem
worse, since dirt tends to hold moisture in contact with wind-
ings. 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.
