■ 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 adjustments.
• Check engine ignition system.
• Inspect entire electrical system.
• Inspect the engine exhaust system.
■ ATTENTION REQUIRED AFTER
SUBMERSION_
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.
■ OPERATION IN HIGH GRASS
OR BRUSH_
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 system becomes extremely hot during operation and
remains hot for a long time after it has shut down.
■ OPERATING PRECAUTIONS_
Never operate the generator set while the vehicle is parked
over dry leaves, dry grass or any other combustible sub¬
stance. The generator's exhaust system becomes extremely
hot and can cause fire if it is too close to combustible mate¬
rials.
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 other enclosed area. Never operate the generator
if it has a leaky exhaust system. Close windows in the vicin¬
ity of the generator exhaust outlet and take any other steps
to prevent exhaust gases from entering rooms or areas occu¬
pied 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 gen¬
erator 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 causes a reduced insulation resistance
and will eventually cause problems. Dirt will make the prob¬
lem worse, since dirt 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 mois¬
ture, when combined, for a good electrical conductor.
