High operating speeds are dangerous and increase risk of personal injury or damage to equipment.The generator supplies correct 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.When adequate engine power is not available engine life may be shortened.The Emission Control System for this generator is warranted for standards set by the Environmental Protection Agency. For warranty information refer to the engine owner’s manual.

SAFETY RULES
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
The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

WARNING!
You must isolate the generator from the electric utility using approved transfer equipment if this unit is used for backup power. Failure to isolate the generator from the power utility may result in injury or death to electric utility workers and damage to the generator due to a backfeed of electrical energy. Whenever the unit is providing backup power, the electric utility must be notified.
DANGER! Generator exhaust gases contain DEADLY carbon monoxide gas. If breathed in sufficient concentrations, carbon monoxide can cause unconsciousness or death. Operate this equipment outdoors where adequate ventilation is available.

  • The generator produces a very powerful voltage that can cause serious injury or death by electrocution. Never touch bare wires or receptacles.
  • Never permit a child or any unqualified person to operate the generator.
  • Never handle any kind of electrical cord or device while standing in water, while barefoot or while hands or feet are wet. Death or serious injury from electrocution may result.
  • Use a ground fault circuit interrupter (GFCI) in any damp or highly conductive area (such as metal decking or steel work).
  • Never use worn, bare, frayed or otherwise damaged electrical cords with the generator. Death, serious injury and property damage from electrical shock may result.
  • Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE. Never allow smoking, open flames, sparks or heat in the vicinity while handling gasoline.
  • Avoid spilling gasoline on a hot engine. Comply with all laws regulating 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 a FIRE or an EXPLOSION.
  • Never store a generator with fuel in the tank where gasoline vapors might reach an open flame, spark or pilot light (as on a furnace, water heater, clothes dryer). FIRE or an EXPLOSION may result.
  • 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.
  • Allow at least 2 feet of clearance on all sides of generator, even while operating unit outdoors, or you could damage the unit.
  • Never start or stop the unit with electrical loads connected to receptacles with the connected devices turned ON.
  • Start the engine and let it stabilize before connecting any electrical loads. Disconnect all electrical loads before shutting down the generator.
  • Do Not insert any object through cooling slots of the engine.You could damage the unit or injure yourself.
  • Never operate the generator: in rain; in any enclosed compartment; when connected electrical devices overheat; 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

Generac-5500-Portable-Generator-fig- \(1\)

The National Electrical Code requires that the frame and external electrically conductive parts of this generator be properly connected to an approved earth ground. Local electrical codes may also require proper grounding of the unit. For that purpose, a GROUNDING WING NUT is provided on the generator end (Figure 1).

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. Be careful to keep the grounding wire attached after connecting the stranded copper wire. However, local codes may vary widely. Consult with a local electrician for grounding requirements in your area.

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.Your generator requires some assembly and is ready for use after it has been properly serviced with the recommended oil and fuel. If you have any problems with the assembly of your generator, please call the generator helpline at 1-800-270-1408.

REMOVE GENERATOR FROM CARTON

  • Set the carton on a rigid flat surface with “This Side Up” arrows pointing upward.
  • Carefully open the top flaps of the shipping carton.
  • Cut carton corners from top to bottom at end of carton near wheels. Lay that side of carton down flat.
  • Remove all packing material, carton fillers, etc.
  • Roll the generator out of the shipping carton.

BEFORE STARTING THE ENGINE
Secure Handle Secure the handle using the following steps:

  • Loosen knobs of the handle.
  • Raise the handle.
  • Insert handle pins, if equipped (P/N B4135).
  • Hand tighten knobs.

To fill your engine with oil

  • Place generator on a level surface.
  • Use a long neck funnel OR remove the fuel tank as described in “Fuel Tank”, when adding or changing oil.
  • Follow the oil grade recommendations and oil fill instructions given in the engine owner’s manual.

NOTE
The generator’s revolving field rides on a prelubricated and sealed ball bearing that requires no additional lubrication for the life of the bearing.

Add Gasoline

WARNING!
Never fill fuel tank indoors. Never fill fuel tank when engine is running or hot.Allow unit to cool for two minutes before refueling. Do Not light a cigarette or smoke when filling the fuel tank.

WARNING!
Do Not overfill the fuel tank. See decal on tank.

  • Use fresh, clean regular UNLEADED gasoline. Do Not use premium gasoline. Do Not mix oil with gasoline. Never use engine or carburetor cleaner products in the fuel tank.
  • Clean area around fuel fill and remove fuel cap/gauge.
  • Slowly add gasoline to fuel tank.Allow about 1.5″ of tank space for fuel expansion (Figure 2).
  • Figure 2 — Typical Fuel Expansion Space
  • Install fuel cap and permit any spilled gasoline to evaporate.

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. Be sure to review “Storage” on page 11.
Fuel Tank

As is common with all plastic fuel containers, the removable fuel tank supplied with this generator may swell or expand due to build-up of fuel vapors when the vent knob is closed.This tank is designed and has been tested to safely withstand pressure-buildup.The ‘ballooning’ condition is relieved by turning the vent knob fully counterclockwise or loosening and retightening the fuel cap/gauge.When installing the tank on your generator, relieve tank pressure before tightening the four large plastic wing nuts.
IMPORTANT: The vent knob should be closed whenever you move the generator or transport the fuel tank.

ASSEMBLY

  1. Turn the vent knob fully clockwise on the fuel gauge to close it (Figure 3).
  2. Turn the fuel shut off valve to the “Off” position (Figure 4).
  3. Disconnect the quick connect on the fuel line by pushing on the metal tab and twisting apart (Figure 5).
  4. Release the metal tab. Some fuel that is left in the line will spill out.
  5. Remove the four large plastic wing nuts holding the tank onto the frame by turning them counterclockwise (Figure 6).
  6. Lift off the fuel tank by grasping the handle (provided on the tank) with one hand and putting the other hand in the finger pocket (Figure 7). Lift the tank straight up.
  7. IMPORTANT: The fuel tank MUST be filled with it lying flat, not slanted or standing upright (Figure 8). Do Not let the fuel valve and quick connect come in contact with any dirt.Generac 5500 Portable Generator Owner’s Manual Featured Image: No file chosen Update Post Add MediaVisualText Paragraph P Close dialog Add media Actions Upload filesMedia Library Filter mediaFilter by type Uploaded to this post Filter by date All dates Search Media list Showing 12 of 12 media items UPLOADING 12 / 20 – Generac-5500-Portable-Generator-fig- \(9\).JPG ATTACHMENT DETAILS Generac-5500-Portable-Generator-fig-8.jpg October 27, 2023 30 KB 568 by 230 pixels Edit Image Delete permanently Alt Text Learn how to describe the purpose of the image\(opens in a new tab\).

Connecting Electrical Loads

  • Let engine stabilize and warm up for a few minutes after starting.
  • Plug in and turn on the desired 120 and/or 240 Volt AC, single phase, 60 Hz electrical loads.
  • Do Not connect 240 Volt loads to the 120 Volt receptacles.
  • Do Not connect 3–phase loads to the generator.
  • Do Not connect 50 Hz loads to the generator.
  • DO NOT OVERLOAD THE GENERATOR. See“Don’t Overload the Generator” on page 9. Stopping the Engine
  • Unplug all electrical loads from generator panel receptacles. Never start or stop engine with electrical devices plugged in and turned on.
  • Let engine run at no–load for 30 seconds to stabilize the internal temperatures of engine and alternator.
  • Move rocker switch to “Off”.
  • Close the fuel shut–off valve.

RECEPTACLES
The control panel is equipped with a flip-up panel to keep the outlets clean and protected. 120 Volt AC, 20 Amp, Duplex

Receptacle
Each receptacle (Figure 11) is protected against overload by a push–to–reset circuit breaker. Use each receptacle to operate 120 Volt AC, single–phase, 60 Hz electrical loads requiring up to 2,400 watts (2.4 kW)at 20 Amps of current. Use cord sets that are rated for 125 Volt AC loads at 20 Amps (or greater). 120/240 Volt AC, 30 Amp, Locking Receptacle Use a NEMA L14–30 plug with this receptacle. Connect a
4–wire cord set rated for 250 Volt AC loads at 30 Amps (or greater) (Figure 12).You can use the same 4–wire cord if you plan to run a 120 Volt load

This receptacle powers 120/240 Volt AC, 60 Hz, single phase loads requiring up to 3,600 watts of power at 30 Amps for 120 Volts; 5,500 watts of power (5.5 kW) at 22.9 Amps for 240 Volts.The outlet is protected by a push–to–reset circuit breaker.

CAUTION! Although this outlet is rated for 120/240 Volt 30 Amp (up to 7,200 watts), the generator is only rated for 5,500 watts. Powering loads that exceed the wattage/amperage capacity of the generator can damage it or cause serious injuries. 240 Volt loads powered through this outlet should not exceed 22.9 Amps of current draw.

DON’T OVERLOAD YOUR GENERATOR
Capacity
You must make sure your generator can supply enough rated (running) and surge (starting) watts for the items you will power at the same time. Follow these simple steps:

  1. Select the items you will power at the same time.
  2. Total the rated (running) watts of these items.This isthe amount of power your generator must produce to keep your items running. See Figure 13.
  3. Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator.
  4. Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.

Surge Watts

  • Total Rated (Running) Watts = 3075
  • Highest Additional Surge Watts = 1800
  • Total Generator Output Required = 4875

Power Management
To prolong the life of your generator and attached devices, it is important to take care when adding electrical loads to your generator.There should be nothing connected to the generator outlets before starting it’s engine.The correct and safe way to manage generator power is to sequentially add loads as follows:

  1. With nothing connected to the generator, start the engine as described in this manual.
  2. Plug in and turn on the first load, preferably the largest load you have.
  3. Permit the generator output to stabilize (engine runs smoothly and attached device operates properly Plug in and turn on the next load.
  4. Again, permit the generator to stabilize.
  5. Repeat steps 4 and 5 for each additional load. Never add more loads than the generator capacity.Take special care to consider surge loads in generator capacity, as described above.
  6. Wattages listed are approximate only. Check tool or appliance for actual wattage.

GENERAL MAINTENANCE RECOMMENDATIONS
The Owner/Operator is responsible for making sure that all periodic maintenance tasks are completed on a timely basis; that all discrepancies are corrected; and that the unit is kept clean and properly stored. Never operate a damaged or defective generator. Engine Maintenance See engine owner’s manual for instructions.
CAUTION! Avoid prolonged or repeated skin contact with used motor oil. Used motor oil has been shown to cause skin cancer in certain laboratory animals.Thoroughly wash exposed areaswith soap and water.

KEEP OUT OF REACH OF CHILDREN. DON’T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.

Generator Maintenance
Generator maintenance consists of keeping the unit clean and dry. Operate and store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air slots in the generator must not become clogged with snow, leaves or any other foreign material.
NOTE: Do Not use a garden hose to clean generator. Water can enter engine fuel system and cause problems. In addition, if water enters generator through cooling air slots, some of the water will be retained in voids and cracks of the rotor and stator winding insulation.Water and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.

To Clean the Generator

  • Use a damp cloth to wipe exterior surfaces clean.
  • A soft bristle brush may be used to loosen caked on dirt or oil.
  • A vacuum cleaner may be used to pick up loose dirt and debris.
  • Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and opening on generator.These openings must be kept clean and unobstructed.

STORAGE

The generator should be started at least once every seven days and allowed to run at least 30 minutes. If this cannot be done and you must store the unit for more than 30 days, use the following guidelines to prepare it for storage.

Generator Storage

  • Clean the generator as outlined in “To Clean the Generator.”
  • Check that cooling air slots and openings on generator are open and unobstructed.

CAUTION! Storage covers can be flammable. Do Not place a storage cover over a hot generator. Let the unit cool for a sufficient time before placing the cover on the unit.

Engine Storage
See engine owner’s manual for instructions. Other Storage Tips

  • Always store unit with fuel shut off valve in the “Off” position (Figure 4, earlier).
  • To prevent gum from forming in fuel system or on essential carburetor parts, empty entire contents of both supplied fuel stabilizer containers into fuel tank and fill with fresh gasoline.
  • Run the unit for several minutes to circulate the additive through the carburetor.The unit and fuel can then be stored for up to 24 months.
  • Additional fuel stabilizer can be purchased locally.
  • Fuel tank may swell in storage if vent is closed.When storing generator with fuel in the tank, make sure the vent knob is turned fully counter-clockwise.
  • Store unit in clean and dry area.
