EQUIPMENT DESCRIPTION SAFETY RULES
This generator is an engine-driven, revolving field, alternating current (AC) generator. It was designed to supply electrical power for operating compatible electrical lighting, appliance, tool and motor loads. This manual contains information for a generator that operates 120 and/or 240 Volts, single phase, 60Hz devices that require up to 7500 watts (7.5 kW) of power that pull up to 62.5 Amps at 120 Volts or
31.2 Amps at 240 Volts.
CAUTION: Do Not exceed the generator’s A wattage/amperage capacity. Add up the rated
watts of all devices you are connecting to generator receptacles at one time. This total should not be greater than 7,500 watts for this generator. In most cases rated watts of the electrical device can be found on the device nameplate. If the device nameplate gives only volts and amps, multiply volts times amps to obtain watts (volts x amps = watts).
The generator’s revolving field is driven at about 3600 rpm by a single cylinder engine.
Every effort has been expended to make sure that the information in this manual is both accurate and current. However, Generac reserves the right to change, alter or othenwise improve the product at any time without prior notice.
DANGER: Do Not tamper with engine A governed speed. High operating speeds are
dangerous and increase risk of personal injury or damage to equipment. The generator supplies correctly rated frequency and voltage only when running at proper governed speed. Incorrect frequency and/or voltage can damage some connected electrical loads. Operating at excessively low speeds Imposes a heavy load at such reduced speeds, when adequate engine power is not available, and may shorten engine life.
This generator set was designed and manufactured for specific applications. Do Not attempt to modify the unit or use it for any application it was not designed for. If you have any questions about your generator’s application, ask your dealer or consult the factory.
The manufacturer could not possibly anticipate every circumstance that might involve a hazard. For that reason, warnings in the manual and warnings on tags or decals affixed to the unit are not all-inclusive, if you intend to handle, operate or service the unit by a procedure or method not specifically recommended by the manufacturer, first make sure that such a procedure or method will not render this equipment unsafe or pose a threat to you and others.
Read this manual carefully and become familiar
with your generator set. Know its applications, its
limitations and any hazards involved.
WARNING: 0
The engine exhaust from this product contains chemicals known to the State
of California to cause cancer, birth defects, or other reproductive harm.
The generator produces a very powerful voltage that can cause extremely dangerous electrical shock. Avoid contact with bare wires, terminals, etc. Never permit any unqualified person to operate or service the generator.
Never handle any kind of electrical cord or device while standing in water, while barefoot or while hands or feet are wet.
The National Electric Code requires the frame and external electrically conductive parts of generator be properly connected to an approved earth ground. Local electrical codes may also require proper grounding of the generator. Consult with a local electrician for grounding requirements in your area.
Use a ground fault circuit interrupter in any damp or highly conductive area (such as metal decking or steel work).
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.

BEFORE STARTING THE ENGINE
Perform the following tasks before trying to start the generator engine:
Add Engine Oil____________________
NOTE: In the future, When adding oil to the engine crankcase use only high quality detergent oil rated with API service classification SF and SG. Use no special additives. DO NOT USE SAE 10W-40.
Select the oil’s viscosity grade according to your expected operating temperature:
colder |
32° F |
' warmer |
5W-30 |
—I- |
10W-30 |
|
Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level frequently to avoid possible damage from running low on oil. See the engine owner’s manual for further information.
To add oil to the engine:
•Place generator on a level surface.
•Clean area around oil fill and remove oil cap.
•Slowly add oil through the oil fill opening until it reaches the top. DO NOT OVERFILL.
•Install oil cap, hand tighten securely.
CAUTION: Any attempt to crank or start the A engine before it has been properly serviced
with the recommended oil will result in an engine failure.
NOTE: The generator’s revolving field rides on a pre lubricated and sealed ball bearing that requires no additional lubrication for the life of the bearing.
Add Fuel
DANGER: NEVER fill fuel tank indoors. A NEVER fill fuel tank when engine is running or
hot. Do Not light a cigarette or smoke when filling the fuel tank.
CAUTION: Do Not overfill the fuel tank. A Always allow room for fuel expansion.
Use only regular UNLEADED gasoline.
IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter, fuel hose or tank during storage. Also, experience indicates that alcohol-blended fuels {called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.
