Generac Portable Products 7500EXL Extended Life Generator
Do Not use worn, bare, frayed or otherwise
damaged eiectricai cord sets with the generator.
Operate generator only on level surfaces and where
it will not be exposed to excessive moisture, dirt,
dust or corrosive vapors.
Gasoline is highly FLAMMABLE and its vapors are
EXPLOSIVE. Do Not permit smoking, open flames,
sparks or heat in the vicinity while handling gasoline.
Avoid spilling gasoline on a hot engine. Comply with
all regulations requiring storage and handling of
gasoline.
Do Not overfill the fuel tank. Always allow room for
fuel expansion. If tank is overfilled, fuel can overflow
onto a hot engine and cause FIRE or an
EXPLOSION.
Never store generator with fuel in tank where
gasoline vapors might reach an open flame, spark or
pilot light (as on a furnace, water heater or clothes
dryer). FIRE or an EXPLOSION might result.
Generator exhaust gases contain DEADLY carbon
monoxide gas. This dangerous gas, if breathed in
sufficient concentrations, can cause
unconsciousness or even death. Operate this
equipment only in the open air where adequate
ventilation is available.
The unit requires an adequate flow of cooling air for
its continued proper operation. Never operate the
unit inside any room or enclosure where the free
flow of cooling air into and out of the unit might be
obstructed. Without sufficient cooling air flow, the
unit quickly overheats, damaging the generator or
nearby property.
Allow at least 2 feet of clearance on ail sides of
generator, even while operating unit outdoors, or
you could damage the unit. Review Cold Weather
Operation on page 9.
Never start or stop the unit with electrical loads
connected to receptacles AND with the connected
devices turned ON. Start the engine and let it
stabilize before connecting electrical loads.
Disconnect ail electrical loads before shutting down
the generator.
• Never operate generator;
in rain; in any enclosed compartment; if engine
speed changes; if connected electrical devices
overtieat; if electrical output is lost; if engine or
generator sparks: if flame or smoke is observed
while unit is running; if unit vibrates excessively.
GROUNDING THE
GENERATOR
The National Electric Code requires the frame and
external electrically conductive parts of generator be
properly connected to approved earth ground. Local
eiectricai codes may also require proper grounding of
the unit. For that purpose, a GROUNDING WING NUT
(Figure 1) Is provided on the cradle frame.
Figure 1 — Grounding Wing Nut
Generally, connecting a No. 12 AWG (American Wire
Gauge) stranded copper wire to the grounding wing
nut and to an earth-driven copper or brass grounding
rod (electrode) provides adequate protection against
electrical shock. However, local codes may vary
widely. Consult with a local electrician for grounding
requirements in your area. Be sure to keep the
grounding wire secure while you connect to the
grounding rod.
Properly grounding the generator helps prevent
electrical shock if a ground fault condition exists in the
generator or in connected electrical devices. Proper
grounding also helps dissipate static electricity, which
often builds up in ungrounded devices.
