Equipment Description

Read this manual carefully and become familiar with your generator. Know its

applications, its limitations and any hazards involved.

The generator is an engine–driven, revolving field, alternating current (AC) generator. It was designed to supply electrical power for operating compatible electrical lighting, appliances, tools and motor loads. The generator’s revolving field is driven at about 3,600 rpm by a singlecylinder engine. The generator is operated on liquefied propane (LP) gas. It can operate on natural gas (NG) fuel only after conversion by a licensed professional gaseous fuel technician.

This generator incorporates GFCI (Ground Fault Circuit Interrupter) outlet protection and has its neutral bonded to grounding fastener to comply to OSHA inspections on job sites.

This generator will not function when connected to a 2 pole transfer switch since its service disconnect also has a neutral bonded to ground. When both the generator and the home or building’s service disconnect contains a neutral bonded to ground, the generator’s GFCI will open and no outlets will function.

A switching neutral transfer switch MUST be used if the generator is connected to a building’s electrical system.

This product is intended for residential use as an allweather temporary source of electric power. It is capable of supplying power to loads such as heating, refrigeration systems, and communication systems. This product does not qualify for emergency standby as defined by NFPA 70 (NEC). DO NOT use this generator for anything other than it’s intended purpose.

Every effort has been made to ensure that the information in this manual is both accurate and current. However, the manufacturer reserves the right to change, alter or otherwise improve the generator and this documentation at any time without prior notice.

• DO NOT remove the neutral bond.

• Removing the neutral bond could result in death, bodily injury and/or property damage.

GFCI will not function if neutral bond removed

DANGER

• See “Don’t Overload Generator”.

• Start generator and let engine stabilize before connecting electrical loads.

• Connect electrical loads in OFF position, then turn ON for operation.

• Turn electrical loads OFF and disconnect from generator before stopping generator.

Exceeding generators wattage/amperage capacity can damage generator and/or electrical devices connected to it.

CAUTION

• Use generator only for intended uses.

• If you have questions about intended use, ask dealer or contact Briggs and Stratton.

• Operate generator only on level surfaces.

• Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation.

• The access door and roof must be installed whenever the unit is running.

• DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.

• DO NOT start engine with air cleaner or air cleaner cover removed.

• DO NOT insert any objects through cooling slots.

• DO NOT use the generator or any of its parts as a step. Stepping on the unit can cause stress and break parts. This may result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, etc..

• If connected devices overheat, turn them off and disconnect them from generator.

• Shut off generator if:

-electrical output is lost;

-equipment sparks, smokes, or emits flames;

-unit vibrates excessively.

Improper treatment of generator can damage it and shorten its life.

CAUTION

• FOR RESIDENTIAL USE ONLY. DO NOT use this generator for anything other than its intended purpose.

• DO NOT tamper with governed speed. Generator supplies correct rated frequency and voltage when running at governed speed.

• DO NOT modify generator in any way.

Excessively high operating speeds increase risk of injury and damage to generator.

Excessively low speeds impose a heavy load.

CAUTION

When adjusting or making repairs to your generator:

• Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.

When testing for engine spark:

• Use approved spark plug tester.

• DO NOT check for spark with spark plug removed.

Unintentional sparking can result in fire or electric shock.

WARNING

Ground Fault Protection

The generator’s receptacles are equipped with Ground Fault Circuit Interrupter (GFCI) protection. This GFCI device meets applicable federal, state and local codes.

The GFCI protects against electrical shock that may be caused if your body becomes a path in which electricity travels to reach the ground. This could happen if you touch a “Live” appliance or wire, or are touching plumbing or other materials that connect to the ground.

When protected by a GFCI device, one may still feel a shock, but the GFCI should cut current off quickly enough so that a person in normal health should not suffer any serious electrical injury.

Connections

to a Building’s Electrical

System

Connections from this generator to a building’s electrical system must be made through a switching neutral transfer switch installed by a qualified electrician. The connection must isolate the generator power from utility power, and must comply with all applicable laws and electrical codes.

IMPORTANT: A switching neutral transfer switch MUST

be used when switching between utility and generator power.

Don’t Overload 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 is the 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. 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.

Example:

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).

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 surge loads in generator capacity, as described above.

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

Maintenance Schedule

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

General Recommendations

Regular maintenance will improve the performance and extend the life of the generator. See any authorized Briggs & Stratton dealer for service. Never operate a damaged or defective generator. To receive full value from the warranty, the operator must maintain the generator as instructed in this section.

All service and adjustments should be made at least once each season. Follow the requirements in the “Maintenance Schedule” chart above.

NOTE: Once a year you should clean or replace the spark plug and replace the air filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.

NOTE: The alternator assembly rotates on a prelubricated and sealed ball bearing that requires no additional lubrication for the life of the bearing.

Emissions Control

Maintenance, replacement or repair of the emissions control devices and systems may be performed by any non-road engine repair establishment or individual. See “Emissions Control System Warranty”.

Maintenance

Maintenance consists of keeping the unit clean. Operate the unit in an environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air louvers on the enclosure must not become clogged with snow, leaves, or any other foreign material. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed.

Check the cleanliness of the unit frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior/interior surface.

NOTE: DO NOT use direct spray from a garden hose to clean generator. Water can enter the engine and generator and cause problems.

Clean Debris

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt or oil.

• Use a vacuum cleaner to pick up loose dirt and debris.

1 Change oil sooner when operating under dirty or dusty conditions. 2 Replace more often under dirty or dusty conditions. 3 Check yearly only. 4 Clean more often under dirty or dusty conditions. 5 Replace every five years.

Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris. Use the same instructions given above for the engine.

Oil

Oil Recommendations NOTE: When adding oil to the engine crankcase, use

only high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. DO NOT use special additives.

1. Choose a viscosity according to the following table:

*Check oil level frequently at higher temperatures.

NOTE: Synthetic oil meeting ILSAC GF-2, API certification mark and API service symbol with “SJ/CF ENERGY CONSERVING” or higher, is an acceptable oil at all temperatures. Use of synthetic oil does not alter required oil change intervals.

SAE 30: 40 °F and higher (5 °C and higher) is good for all purpose use above 40°F, use below 40°F will cause hard starting.

10W-30: 0 to 100 °F (-18 to 38 °C) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80°F (27°C) or higher.

Synthetic 5W-30: -20 to 120 °F (-30 to 40 °C) provides the best protection at all temperatures as well as improved starting with less oil consumption.

5W-30: 40 °F and below (5 °C and below) is recommended for winter use, and works best in cold conditions.

Checking and Adding 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 unit is on a level surface.

2. Remove roof (see Removable Roof and Battery Access section).

3. Remove oil fill cap/dipstick and wipe clean with cloth.

4. Verify oil level is at the FULL mark on dipstick (Figure 14).

* Natural gas rating will depend on specific fuel but typical derating of generator is between

10 to 20% off the LP gas rating. The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002-05). Given both the wide array of products on which our engines are placed, and the variety of environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece of power equipment (actual “on-site” power). This difference is due to a variety of factors including, but not limited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to reduce friction and clean out of combustion chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values derived using the foregoing codes.

Emissions Control System Warranty Statement

(Owner’s Defect Warranty Rights and Obligations)

California, United States and Canada Emissions Control Defects Warranty Statement

The California Air Resources Board (CARB), U.S. EPA and B&S are pleased to explain the Emissions Control System Warranty on your small off–road engine (SORE). In California, new small off–road engines model year 2006 and later must be designed, built and equipped to meet the State’s stringent anti–smog standards. Elsewhere in the United States, new non–road, spark–ignition engines certified for model year 1997 and later must meet similar standards set forth by the U.S. EPA. B&S must warrant the emissions control system on your engine for the periods of time listed below, provided there has been no abuse, neglect or improper maintenance of your small off–road engine.

Your emissions control system includes parts such as the carburetor, air cleaner, ignition system, fuel line, muffler and catalytic converter. Also included may be connectors and other emissions related assemblies.

Where a warrantable condition exists, B&S will repair your small off–road engine at no cost to you including diagnosis, parts and labor.

Briggs & Stratton Emissions Control Defects Warranty Coverage

Small off–road engines are warranted relative to emissions control parts defects for a period of two years, subject to provisions set forth below. If any covered part on your engine is defective, the part will be repaired or replaced by B&S.

Owner’s Warranty Responsibilities

As the small off–road engine owner, you are responsible for the performance of the required maintenance listed in your Operating and Maintenance Instructions. B&S recommends that you retain all your receipts covering maintenance on your small off–road engine, but B&S cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the small off–road engine owner, you should however be aware that B&S may deny you warranty coverage if your small off–road engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.

You are responsible for presenting your small off–road engine to an Authorized B&S Service Dealer as soon as a problem exists. The undisputed warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you should contact a B&S Service Representative at 1–414–259–5262.

The emissions warranty is a defects warranty. Defects are judged on normal engine performance. The warranty is not related to an in–use emissions test.
