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:
During Generator Use
If circuit breaker trips during use, it usually indicates faulty electrical equipment or cords. However, test the circuit breaker as follows;
NOTICE If circuit breaker tests correctly:
Use battery float charger jack to keep the starting battery charged and ready for use. Battery charging should be done ina dry location, such as inside a garage.
NOTICE See Battery Maintenance for additional information.
NOTICE Always unplug the battery float charger before starting the generator.
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 will cause the unit not to start or shut down during operation.
2. Turn the fuel valve (A) to the “On” position.
3. Push engine rocker switch to on position (1).
4. Push choke lever (B) to “Choke” position.
5A. For electric starting, push and hold the start switch in “Start” position until generator starts. To prolong the life of starter components, DO NOT hold start switch in “Start” position for more than 5 seconds, and pause for at least 1 minute between starting attempts.
NOTICE If battery is discharged, use manual starting instructions.
5B. For manual starting, grasp recoil handle and pull slowly until slight resistance is felt. Then pull rapidly one time only to start engine.
6. Move choke lever to “Half” choke position, and pull recoil handle twice or push and hold the start switch in the “Start” position as described in step 5A.

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. If so, oil must be at proper level for engine to start.
If engine oil pressure drops below a preset level, an oil switch will stop the engine. Check oil level with dipstick.
If oil level is hetween ADD and FULL mark on dipstick:
If oil level is helow ADD mark on dipstick:
Your generator has the capability of recharging a discharged 12 Volt automotive or utility style storage battery.
To recharge 12 Volt batteries, proceed as follows:
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.
Follow the hourly or calendar intervals, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.
First 5 Hours
Every 8 Hours or Daily
Every 25 Hours or Yearly
Every 50 Hours or Yearly
Every 100 Hours or Yearly
Every 250 Hours or Yearly
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.
Some adjustments will need to be made periodically to properly maintain your generator.
All service and adjustments should be made at least once gach season. Follow the requirements in the Maintenance Schedule chart above.
NOTICE 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 he performed hy any non-road engine repair establishment or individual.
However, to obtain “no charge” emissions control service, the work must be performed by a factory authorized dealer. See the Emissions Warranty.
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.
NOTICE 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. Keep the area around and behind the muffler free from any combustible debris. 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 could damage it and shorten its life.
Other than float charging, described elsewhere, no maintenance is required for the starting battery. Keep the battery and terminals clean and dry.
NOTICE Battery charging should be performed in a dry location, such as inside a garage.
The fuel valve is equipped with a fuel sediment cup, screen, retaining ring and o-ring that need to be cleaned.
1. Move fuel valve to “Off” position.
2. Remove sediment cup (A) from fuel valve. Remove o-ring (B), retaining ring (C) and screen (D) from fuel valve.
3. Wash sediment cup, o-ring, retaining ring, and screen in a nonflammable solvent. Dry them thoroughly.
4. Place screen, retaining ring, and o-ring into fuel valve. Install sediment cup and tighten securely.
5. Move fuel valve to “On” position, and check for leaks. Replace o-ring if there is any leakage.
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, SG, SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.
Checking Oil Level
Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil level maintained.
Adding Engine Oil
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.
KEEP OUT OF REACH OF CHILDREN. DON'T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.
Change the oil while the engine is still warm from running, as follows:
1. Make sure unit is on a level surface.
2. Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.
3. Clean area around oil drain plug (A). The oil drain plug is located at base of engine, under recoil.
4. Remove oil drain plug and drain oil completely into a suitable container.
5. Reinstall oil drain plug and tighten securely. Remove oil cap/dipstick.
6. Slowly pour recommended oil (about 28 oz.) into oil fill opening. Pause to permit oil to settle. Fill to “Full” mark on dipstick.
7. Wipe dipstick clean each time oil level is checked. DO NOT overfill.
8. Reinstall cil cap/dipstick. Tighten cap securely.
9. Wipe up any spilled oil.
Service Air Cleaner
Your engine will not run properly and may be damaged if you run it with a dirty air cleaner. Clean or replace more often if operating under dusty or dirty conditions.
To service the air cleaner, follow these steps:
1. Loosen screws (B) and remove air cleaner cover (CG).
2. Carefully remove foam pre-filter (D) and paper filter (E).
3. Wipe clean inside of base (F) and cover thoroughly.
4. Clean or replace the foam pre-filter. To clean, wash pre- filter in a solution of household detergent and warm water, then rinse thoroughly. Squeeze dry in a clean cloth.
5. Clean paper filter by tapping it gently on a solid surface. If the paper filter is too dirty, replace it with a new one. Dispose of the old filter properly.
6. Insert the foam pre-filter into the air cleaner cover, then the paper filter.
7. Assemble air cleaner cover onto base and tighten screws.
Service Spark Plug
Changing the spark plug will help your engine to start easier and run better.
Inspect the muffler for cracks, corrosion, or other damage. Remove the spark arrester, if equipped, and inspect for damage or carbon blockage. If replacement parts are required, make sure to use only original equipment replacement parts.
Clean and inspect the spark arrester as follows:
1. To remove muffler heat shield (A) from muffler (B), remove four screws that connect guard to muffler bracket.
2. Remove four screws that attach spark arrester screen (CG).
3. Inspect screen and obtain a replacement if torn, perforated or otherwise damaged. DO NOT use a defective screen. If screen is not damaged, clean it with commercial solvent.
4. Reattach screen and muffler guard.
Clean Cooling System
Over time debris may accumulate in cylinder cooling fins and cannot be observed without partial engine disassembly. For this reason, we recommend you have an authorized service dealer clean the cooling system (D) per recommended intervals (see Maintenance Schedule in the Maintenance section). Equally important is to keep top of engine free from debris. Also see Cleaning.
Regular valve clearance check and adjustment will improve performance and extend engine life. This procedure cannot be done without partial engine disassembly and the use of special tools. For this reason we recommend that you have an authorized Service Dealer check and adjust valve clearance at recommended intervals (see Maintenance Schedule in the Maintenance section).
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped with a non-adjustable idle mixture valve. Top speed has been set at the factory. If adjustment is required, see an authorized service dealer.
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
Long Term Storage Instructions
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 Briggs &Stratton® Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs & Stratton genuine service parts are sold.
For engines equipped with a FRESH START® fuel cap, use Briggs & Stratton FRESH START® available in a drip concentrate cartridge.
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. 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.
While engine is still warm, drain oil from crankcase. Refill with recommended grade. See Changing Engine Oil in Engine Maintenance.
