Operation

Starting the Engine

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

1. Make sure unit is on a level surface.

IMPORTANT: Failure to start and operate the unit on a level surface will cause the unit not to start or shut down during operation.

2. Turn fuel valve to “On” position. Fuel valve handle should be vertical (pointing toward ground) for fuel to flow.

3. Push choke lever to “Choke” position.

4. Push engine rocker switch to “On”.

5. Grasp recoil handle and pull slowly until slight resistance is felt. Then pull handle rapidly to overcome compression, prevent kickback, and start engine.

WARNING

Starter cord kickback (rapid retraction) can result in bodily injury. Kickback will pull hand and arm toward engine faster than you can let go.

Broken bones, fractures, bruises, or sprains could result.

• When starting engine, pull cord slowly until resistance is felt and then pull rapidly to avoid kickback.

• NEVER start or stop engine with electrical devices plugged in and turned on.

IMPORTANT: If excessive fuel is present in the air/fuel mixture causing a “flooded” condition, move the choke lever to “Run” ( ) position and pull the handle repeatedly until the engine starts.

6. Move choke lever to “Run” ( ) position a short distance at a time over several seconds in warm weather or minutes in cold weather. Let engine run smoothly before each change. Operate with choke in

“Run” position.

WARNING

Contact with muffler area can result in serious burns.

Exhaust heat / gases can ignite combustibles, structures or damage fuel tank causing a fire.

• DO NOT touch hot parts and AVOID hot exhaust gases.

• Allow equipment to cool before touching.

• Keep at least 5 feet (1.5 m) of clearance on all sides of generator including overhead.

• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and

Public Property require equipment powered by an internal combustion engine to have a spark arrester, maintained in effective working order, complying to USDA Forest service standard 5100-1C or later revision. In the State of California a spark arrester is required under section 4442 of the California

Public resources code. Other states may have similar laws.

NOTE: If the engine starts after 3 pulls but fails to run, or if the unit shuts down during operation, make sure the unit is on a level surface and check for the proper oil level in the crankcase. This unit may be equipped with a low oil protection device.

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 Wattage Reference Guide.

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.

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 its 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.

General Recommendations

Regular maintenance will improve the performance and extend the life of the generator. See an authorized Briggs &

Stratton 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.

Some adjustments will need to be made periodically to properly maintain your generator.

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.

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 in Warranty section.

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 water or other liquids to clean generator.

Liquids can enter engine fuel system, causing poor performance and/or failure to occur. In addition, if liquid enters generator through cooling air slots, some of the liquid will be retained in voids and cracks of the rotor and stator winding insulation. Liquid and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.

Cleaning

Daily or before use, look around and underneath the generator for signs of oil or fuel leaks. Clean accumulated debris from inside and outside the generator. Keep the linkage, spring and other engine controls clean. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed.

Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris:

• Use a damp cloth to wipe exterior surfaces clean.

NOTICE

Improper treatment of generator can 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.

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

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