Operator Safety

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.

Ground Fault Protection

This unit is equipped with a Ground Fault Circuit Interrupter (GFCI). This device meets applicable federal, state and local codes.

The GFCI protects against electrical shock that may be caused if your body becomes a path which electricity travels to reach 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, 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.

Test GFCI Circuit Breaker

Test your GFCI circuit breaker every month, as follows:

1. While generator is running, push white “Test” button.

The circuit breaker should trip (handle will move to approximate center position), which will disconnect power to outlets.

NOTICE

If circuit breaker does not trip:

• DO NOT use generator.

• Call a Briggs & Stratton Power Products service center.

2. If handle moves to center, reset circuit breaker by

firmly moving handle to “Off” (down) position, then to “On” (up) position.

NOTICE

If circuit breaker does not reset properly:

• DO NOT use generator.

• Call a Briggs & Stratton Power Products service center.

During Generator Use

If circuit breaker trips during use, it usually indicates faulty electrical equipment or cords. However, test the circuit breaker as follows;

1. Disconnect loads, reset and test circuit breaker as described earlier. Let generator run without any loads for 1 minute.

NOTICE

If circuit breaker trips in the 1 minute period:

• DO NOT use generator.

• Call a Briggs & Stratton Power Products service center.

2. If circuit breaker tests correctly, the electrical equipment or extension cords may be faulty. Replace faulty electrical equipment and cords before further use.

NOTICE

If circuit breaker tests correctly:

• Have qualified personnel check all electrical equipment and cords for any defects.

• Replace electrical equipment and cords or take to a qualified repair center.

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.

NOTICE Failure to start and operate the unit on a level surface could cause the unit not to start or shut down during operation.

2. Turn the fuel valve (A) to the “On” position.

3. Make sure idle control switch is in “Off” position.

4. Start engine according to instructions given in the engine operator’s manual.

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

Connecting Electrical Loads

1. Let engine stabilize and warm up for a few minutes after starting.

2. Plug in and turn on the desired 120 and/or 240 Volt AC, single phase, 60 Hz electrical loads.

NOTICE

• DO NOT connect 240 Volt loads to the 120 Volt duplex 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 Generator.

NOTICE

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

• DO NOT exceed the generator’s wattage/amperage capacity. See Don’t Overload Generator in the Operation section.

• 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.

WARNING Starter cord kickback (rapid retraction) will

pull hand and arm toward engine faster than you can let go which could cause broken bones, fractures, bruises, or sprains resulting in

serious injury.

• 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.

WARNING Exhaust heat/gases could ignite

combustibles, structures or damage fuel tank causing a fire, resulting in death,

serious injury and/or property damage. Contact with muffler area could cause burns resulting in serious injury.

• 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.

Contact the original equipment manufacturer, retailer, or dealer to obtain a spark arrester designed for the exhaust system installed on this engine.

• Replacement parts must be the same and installed in the same position as the original parts.

Stopping the Engine

1. Turn OFF and unplug all electrical loads from generator

panel receptacles. NEVER start or stop engine with electrical devices plugged in and turned ON.

2. Move idle control switch to “Off” position.

3. Let engine run at no-load for several minutes to stabilize internal temperatures of engine and generator.

4. Turn engine off according to instructions given in the engine operator’s manual.

5. Move fuel valve to “Off” position.

Operating Automatic Idle Control

This feature is designed to greatly improve fuel economy. When this switch is turned ON, the engine will only run at its normal high governed engine speed when electrical loads are connected. When electrical loads are removed, the engine will run at a reduced speed.

With the switch off, the engine will run at the normal high engine speed. Always have the switch off when starting and

stopping the engine.

Charging a Battery

Your generator has the capability of recharging a discharged 12 Volt automotive or utility style storage battery.

• DO NOT use the unit to charge any 6 Volt batteries.

• DO NOT use the unit to crank an engine having a discharged battery.

To recharge 12 Volt batteries, proceed as follows:

1. Check fluid level in all battery cells. If necessary, add ONLY distilled water to cover separators in battery cells. DO NOT use tap water.

2. If battery is equipped with vent caps, make sure they are installed and are tight.

3. If necessary, clean battery terminals.

4. Connect battery charge cable connector plug to panel receptacle identified by the words “12V 10A D.C.”

5. Connect battery charge cable clamp with red handle to the positive (+) battery terminal.

6. Connect battery charge cable clamp with black handle to the negative (–) battery terminal.

7. Start engine. Let engine run while battery recharges.

8. When battery has charged, shut down engine.

NOTICE Use an automotive hydrometer to test battery state of charge and condition. Follow the hydrometer manufacturer’s instructions carefully. Generally, a battery is considered to be at 100% state of charge when specific gravity of its fluid (as measured by hydrometer) is 1.260 or higher.

• DO NOT allow any open flame, spark, heat, or lit cigarette during and for several minutes after charging a battery.

• Wear protective goggles, rubber apron, and rubber gloves.

• DO NOT continue to charge a battery that becomes hot or is fully charged.

• DO NOT leave battery unattended.

WARNING Battery posts, terminals and related

accessories contain lead and lead compounds - chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
