Operation

Operation

Step 1: Safe Location

Before starting the portable generator there are two equally important safety concerns regarding carbon monoxide poisoning and fire that must be addressed.

Operation Location to Reduce the Risk of Carbon Monoxide Poisoning

The engine exhaust of all fossil fuel burning equipment, such as a portable generator, contains carbon monoxide, a poisonous gas that will kill you in minutes. You cannot smell it, see it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas.

By law in many jurisdictions it is required to have a carbon monoxide alarm in operating condition in your home. A carbon monoxide alarm is an electronic device that detects hazardous levels of carbon monoxide. When there is a buildup of carbon monoxide, the alarm will alert the occupants by flashing visual indicator light and alarm. Smoke alarms cannot detect carbon monoxide gas.

Carbon Monoxide Alarm(s)

Install carbon monoxide alarm inside your home. Without working carbon monoxide alarms, you will not realize you are getting sick and dying from carbon monoxide poisoning.

DANGER! Engine exhaust contains carbon monoxide, a poisonous gas that will kill you in minutes. You cannot smell it, see it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas.

• Operate portable generator only outdoors, at least ft. (6.1 m) from occupied spaces with exhaust pointed away to reduce the risk of carbon monoxide accumulating.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with battery back-up according to the manufacturer’s instructions. Smoke alarms cannot detect carbon monoxide gas.
• Do not run portable generator inside homes, garages, basements, crawlspaces, sheds, or other partiallyenclosed spaces even if using fans or opening doors and windows for ventilation. Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this product has shut off.

If you start to feel sick, dizzy, weak, or your homes carbon monoxide alarm sounds while using this product, get to fresh air right away. Call emergency services. You may have carbon monoxide poisoning

Operation Location to Reduce the Risk of Fire

WARNING! Exhaust heat/gases could ignite combustibles, structures or damage fuel tank causing a fire, resulting in death or serious injury.

• Portable generator must be at least 5 ft. (1.5 m) from any structure, overhang, trees, shrubs, or vegetation over 12 in. (30.5 cm) in height.
• Do not place portable generator under a deck or other type of structure that may confine airflow. Smoke alarm(s) must be installed and maintained indoors according to the manufacturer’s instructions/ recommendations.
• Carbon monoxide alarms cannot detect smoke.
• Do not place portable generator in manner other than shown.

Step 2: Oil and Fuel

1. Move generator outdoors to a flat, level surface.

2. Clean area around oil fill and remove oil fill cap/ dipstick.

3. Using oil funnel (optional), slowly pour contents of provided oil bottle into oil fill opening to the full mark on dipstick.

NOTICE Pause to permit oil to settle. Wipe dipstick clean each time oil level is checked. DO NOT overfill.

4. Replace and fully tighten oil fill cap/dipstick.

Fuel must meet these requirements:

• Clean, fresh, unleaded fuel with a minimum of 87 octane.

• Gasoline with an ethanol content up to 10% is acceptable.

NOTICE Do not mix oil in fuel or modify engine to run on alternate fuels. Use of unapproved fuels could damage engine and will not be covered under warranty. See High Altitude for 5,000 ft. and above.

WARNING! Fuel and its vapors are extremely flammable which could cause burns or fire resulting in death or serious injury.

• Do not refuel during operation.
• Do not smoke during refueling.
• Turn engine off and let it cool at least 2 minutes before removing fuel cap.
• Fill fuel tank outdoors. Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources. Check fuel lines, tank, cap and fittings frequently for cracks or leaks. Replace if necessary.

1. Slowly remove fuel cap to relieve pressure in tank.

2. Slowly add unleaded fuel to fuel tank. Be careful not to fill above bottom lip. This allows adequate space for fuel expansion.

3. Install fuel cap and let any spilled fuel evaporate before starting engine.

High Altitude

At altitudes over 5,000 ft. (1524 m), a minimum 85 octane fuel is acceptable. To remain emissions compliant, high altitude adjustment is required. Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions.

See an authorized Briggs & Stratton dealer for high altitude adjustment information. Operation of the engine at altitudes below 2,500 ft. (762 m) with the high altitutde kilt is not recommended.

Transporting

When transporting equipment with a vehicle or trailer, turn fuel shutoff valve to off (0) position. Do not tip engine or equipment at an angle which causes fuel to spill.

Step 3: Generator Start Up

Disconnect all electrical loads from the generator. Use the following start instructions:

1. Make sure unit is outdoors on a level surface.

NOTICE Failure to operate the unit on a level surface may cause the unit to shut down.

2. Turn the fuel valve to the on (I) position.

3. Push choke lever to choke position.

4. Set engine switch to on (I) position.

5. Grasp recoil handle and pull slowly until slight resistance is felt. Then pull rapidly to start engine.

6. Slowly move choke lever to run position. If engine falters, move choke lever to half choke position until engine runs smoothly, and then to run position.

NOTICE If engine starts but fails to run, see Low Oil Shutdown in Features and Controls.

Step 4: Connecting Electrical Loads

Using Extension Cords

1. Only use grounded cords marked for outdoor use rated for your loads.

2. Follow cord safety instructions.

3. Install carbon monoxide alarm(s).

4. When operating generator with extension cords, make sure it is located in an open, outdoor area, at least 20 ft. (6.1 m.) from occupied spaces with exhaust pointed away.

5. Extension cords running directly into home, powering indoor items IS NOT RECOMMENDED.

DANGER! Engine exhaust contains carbon monoxide, a poisonous gas that will kill you in minutes. You cannot smell it, see it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas.

• Extension cords running directly into the home increase your risk of carbon monoxide poisoning through openings.
• If an extension cord running directly into the home is used to power indoor items, the operator recognizes that this increases the risk of CO poisoning to people inside the home and assumes that risk.

WARNING! Damaged or overloaded extension cords could overheat, arc, and burn resulting in death or serious injury.

NOTICE For generator output required see Generator Capacity. Connect electrical loads in off position then turn on for operation.

120 Volt AC, 20 Amp, Duplex Receptacles

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.

120 Volt AC, 30 Amp, Travel Trailer Receptacle

Use a NEMA TT–30 plug with this receptacle. Connect a 3–wire travel trailer cord set rated for 125 Volt AC loads at 30 Amps to the plug.

This receptacle powers 120 Volt AC, 60 Hz, single phase travel trailer loads requiring up to 3,500 watts (3.5 kW) of power at 29.1 Amps.

Generator Capacity

To make sure your generator can supply enough running watts and starting watts for the items you will power at the same time, follow these three simple steps:

1. Select the items you will power at the same time. See following list for typical wattages.

* Typical wattages listed are approximate only. Check tool or appliance for actual wattage.

** The momentary electrical current the generator can provide to start electric motors, per Briggs & Stratton standard 628K. It does not represent the power required to continuously run electrical loads. It is the maximum current that can momentarily be supplied when starting a motor, multiplied by the generator’s rated voltage.

2. Total the running watts. This is the amount of power your generator must produce to keep your items running. See following example:

Example

Total running watts = 2125

Highest starting watts = 2100

Total generator watts required = 4225

3. Estimate the starting watts you will need. Because not all motors start at the same time, total starting wattage can be estimated by adding only the item with the highest additional starting watts requirements to the total running watts from step 2.

Power Management

To manage generator power, sequentially add loads as follows:

1. With nothing connected to generator, start the engine outdoors.
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).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.

Never add more loads than the generator capacity. Take special care to consider starting loads in generator capacity.

CO Detection

Carbon Monoxide (CO) Shutdown System

CO Detection automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Detection fault occurs. After shutdown, the CO Detection indicator light will blink for at least five minutes per the chart below.

CO Detection DOES NOT replace carbon monoxide alarms. Install battery-powered carbon monoxide alarm(s) in your home. Don’t run generator in enclosed areas

Blue light will blink for five seconds at the startup of generator to show CO Detection functioning properly.

Step 5: Generator Shutdown

1. Turn off and unplug all electrical loads from generator panel receptacles. Never stop engine with electrical devices plugged in and turned on.
2. Let engine run at no-load for one minute to stabilize internal temperatures of engine and generator.
3. Push engine switch to off (0) position.
4. Move fuel valve to off (0) position.

Maintenance

Maintenance Schedule

Follow the hourly or calendar intervals, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.

1 Service more often under dirty or dusty conditions.

2 See any authorized dealer for service.

General Recommendations

Regular maintenance will improve the performance and extend the life of the generator. See any authorized dealer for service.

The generator’s warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the generator as instructed in this manual.

All service and adjustments should be made at least once each season. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer. Follow requirements in Maintenance Schedule.

Emissions Control

Maintenance, replacement, or repair of the emissions control devices and systems may be performed by any nonroad engine repair establishment or individual. However, to obtain ”no charge” emissions control service, the work must be performed by a factory authorized dealer. See Emissions Warranty.

Cleaning

Daily or before use, look around and underneath the generator for signs of oil or fuel leaks. Clean any accumulated debris. Keep area around muffler free from any debris.

• Use a soft bristle brush to loosen caked on dirt or oil.
• Use a damp cloth to wipe exterior surfaces clean.

NOTICE Improper treatment of generator could damage it and shorten its life. Do not expose generator to excessive moisture, dust, dirt, or corrosive vapors. Do not insert any objects through cooling slots.

Fuel Valve Maintenance

The fuel valve is equipped with a fuel sediment cup, screen, and o-ring that need to be cleaned.

1. Move fuel valve to off (0) position.
2. Remove sediment cup from fuel valve. Remove o-ring and screen from fuel valve.

3. Wash sediment cup, o-ring, and screen in a nonflammable solvent. Dry them thoroughly

4. Place screen and o-ring into fuel valve. Install sediment cup and tighten securely.

5. Move fuel valve to on (I) position, and check for leaks. Replace fuel valve if there is any leakage.

Engine Maintenance

Oil Recommendations

We recommend the use of Briggs & Stratton Warranty Certified oils for best performance. Other high-quality detergent oils are acceptable if classified for service SF or higher. Do not use special additives. See Common Service Parts.

Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.

* Below 4°C (40°F) the use of SAE 30 will result in hard starting.

** Above 27°C (80°F) the use of 10W30 may cause increased oil consumption. Check oil level more frequently.

Checking/Adding Engine Oil

Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil level maintained.

1. Make sure generator is on a level surface.
2. Clean area around oil fill, remove dipsitck and wipe with clean cloth. Replace dipstick. Remove and check oil level.

NOTICE Do not screw in dipstick when checking oil level.

3. Verify oil is at full mark on dipstick. Replace and tighten dipstick.

4. If needed, slowly pour oil into oil fill opening to the full mark on dipstick. Do not overfill.

NOTICE Overfilling with oil could cause the engine to not start, or hard starting.

• Do not overfill.
• If over the full mark on dipstick, drain oil to reduce oil level to full mark on dipstick.

5. Replace and tighten dipstick.

NOTICE Do not attempt to crank or start engine before it has been properly serviced with recommended oil. This could result in an engine failure.

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 areas with soap and water.

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

Changing Engine Oil

If you are using your generator under extremely dirty or dusty conditions, or in extremely hot weather, change the oil more often.

Storage

If storing the unit for more than 30 days, use the following guidelines to prepare it for storage.

Long Term Storage Instructions

1. Clean the generator as outlined in Cleaning.
2. Change engine oil while engine is still warm, drain oil from crankcase. Refill with recommended grade. See Changing Engine Oil.
3. Treat or drain fuel from generator as fuel can become stale when stored over 30 days.

Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use a fuel stabilizer

There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel system before storage.

If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Then run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.

WARNING! Fuel and its vapors are extremely flammable and explosive which could cause burns, fire or explosion resulting in death or serious injury.

• When storing fuel or equipment with fuel in tank, store away from furnaces, stoves, water heaters, clothes dryers or other appliances that have pilot light or other ignition source because they could ignite fuel vapors.
• When draining fuel, turn generator engine off and let it cool at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank. Drain fuel tank outdoors. Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.
• Check fuel lines, tank, cap and fittings frequently for cracks or leaks. Replace if necessary.

4. Store generator in clean, dry area and cover with a suitable protective cover that does not retain moisture.

WARNING! Storage covers could cause a fire resulting in death or serious injury.

• Do not place a storage cover over a hot or running generator. Let equipment cool for a sufficient time before placing the cover on the equipment.
