Do not connect this generator to any building’s electrical system unless a licensed

electrician has installed an isolation switch. Failure to do so can result in property damage

or death.

WARNING: FIRE & BURN HAZARDS

The exhaust system gets hot enough to ignite some materials. Keep generator at least 1

(one) meter away from buildings and other equipment during or immediately after

operation.

Never enclose generator in any structure. Keep all flammable materials away from the

generator.

The muffler becomes very hot during operation and remains hot for some time after the

engine stops. Do not touch the muffler while the engine is running or hot.

Allow the engine and the muffler to cool before storing. See storing instructions on page 9

of this manual.

Gasoline is highly flammable and poisonous. Always stop the engine and allow the muffler

to cool before refueling. Never refuel while smoking or in the vicinity of an open flame or

sparks. Never smoke near the generator.

Always check for spilled fuel or fuel leaks. Make sure that any spilled fuel has been wiped

up before starting the generator. When operating or transporting the generator, be sure

that it is kept upright. If the unit tilts, fuel may leak from the carburetor or fuel tank.

1. NEVER TOUCH MOVING PARTS.

Never place your hands, fingers or other body parts near the generator's moving parts.

Never insert your fingers or other objects into the housing's ventilator. Such an action invites the danger of

injuries or electric shocks.

2. NEVER USE GENERATOR FOR APPLICATIONS OTHER THAN THOSE SPECIFIED.

9. Do not enclose the generator nor cover it with a box.

The generator has a built-in forced air cooling system, and may become overheated if it is enclosed.

10.Operate the generator on a level surface.

It is not necessary to prepare a special foundation for the generator. However, the generator will vibrate on an

irregular surface, so choose a level place without surface irregularities. If the generator is tilted or moved

during operation, fuel may spill and/or the generator may tip over, causing a hazardous situation.

Proper lubrication cannot be expected if the generator is operated on a steep incline or slope. In such a case,

piston seizure may occur even if the oil is above the upper level.

11.Pay attention to the wiring from the generator to the connected device.

If the wire is under the generator or in contact with a vibrating part, it may break and possibly cause a fire or

generator burnout.

12.Do not operate in rain or with wet hands.

The operator may suffer severe electric shock if the generator is wet due to rain or snow.

If wet, wipe and dry it well before starting.

Do not pour water directly over the generator, not wash it with water.

13.No smoking while handling the battery.

The battery emits flammable hydrogen gas, which can explode if exposed to electric arcing or open flame.

Keep the area well-ventilated and keep open flames/sparks away when handling the battery.

WARNING: HITACHI electronic controlled products should not be used with portable generators.

Irregular generator power could cause these products to fail.

Regarding other manufacturer's products, please contact the manufacturer to see if it is

safe to use the electronic controlled products with portable generators.

PREPARATION BEFORE OPERATION

Before starting the generator, check the oil and fuel levels. Be sure that the air cleaner is functioning. Follow the

guidelines below when adding oil and fuel.

Fig. 5

English

NOTE: There is no oil in the engine crankcase when the generator is shipped. You must add oil before

starting the engine. Check the oil level before each use with the generator on a level surface and

the engine stopped.

Engine oil is a major factor affecting engine performance and service life. Non-

detergent and 2-stroke oils will damage the engine and are not recommended.

Use 4-stroke motor oil that meets or exceeds the requirements for API service

classification SE or Higher.

Always check the API SERVICE label on the oil container to be sure it includes

the letters SE or Higher. SAE 10W- 30 or 10W-40 is recommended for general,

all-temperature use. Other viscosities shown in Fig.6 may be used when the

average temperature in your area is within the indicated range.

CHECKING THE OIL

1. Remove the oil filler cap and wipe the dipstick clean.

2. Check the oil level by inserting the dipstick into the filler neck without screwing

it in.

3. If the test shows no oil markings, the oil is low.

4. If the level is low, add the recommended oil to the upper mark on the dipstick.

OIL CAPACITY

NOTE: If the oil level is too low, the oil alert system will shutdown

the engine and prevent engine from restarting.

FUEL

WARNING: Gasoline is flammable and its vapor is explosive. To prevent fire or explosion, follow the

guidelines below:

• Keep fuel out of the reach of children.

• Refuel the generator in well-ventilated area. Do not refuel while engine is running or hot. Disconnect all

electrical loads and shut off the engine before refueling.

• Do not overfill the fuel tank. Always allow room for fuel vapors to expand. If you overfill the tank, fuel

can overflow onto the hot engine. This can cause fire or explosion. After refueling, tightly close the fuel

tank cap.

• Do not spill fuel. Fuel or fuel vapor may ignite. If fuel spills, make sure that the area is dry before

starting the engine.

• Never smoke in the refueling area. Never allow open flames or sparks in area.

• Store fuel in an approved container. Store fuel in a well ventilated area free of open flames or sparks.

FUEL TANK CAPACITY

Check the fuel gauge located on the top of the generator near

the fuel tank and refill the tank if the fuel level is low. Refuel

carefully to avoid spilling fuel. Do not fill above the shoulder of

the fuel strainer.

Use unleaded gasoline with a pump octane rating of 86 or

higher.

The engine is certified to operate on unleaded gasoline.

Unleaded gasoline produces fewer engine and spark plug

deposits and extends exhaust system life. Never use stale or

contaminated gasoline. Avoid getting dirt or water in the fuel

tank.

Always keep the fuel strainer in place while refueling.

MAINTENANCE

IMPORTANCE OF MAINTENANCE

Good maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce air

pollution.

WARNING: Improper maintenance or failure to correct a problem before operation can cause

malfunction, serious injury, or death. Always follow the inspection and maintenance

recommendation and schedules in this user’s manual.

The following pages include a maintenance schedule, routine inspection procedures, and

simple maintenance procedures using basic hand tools, to help you properly care for your

generator. If you are not comfortable with any maintenance procedure, have the generator

serviced by a professional technician.

Maintenance, replacement, or repair of the emission control devices and system may be

performed by any engine repair establishment or individual, using parts that are “certified”

to EU standards.

MAINTENANCE SAFETY

WARNING: Always follow the procedures and precautions in the owner’s manual. Failure to

properly follow maintenance instructions and precautions can lead to serious injury or

death.

SAFETY PRECAUTIONS

CAUTION: Make sure that the engine is off before you begin any maintenance or repairs.

This will eliminate several potential hazards, including:

English

• Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you

operate the engine.

• Burns from hot parts. Let the engine and exhaust system cool before you touch it to prevent burns.

• Injury from moving parts. Wear appropriate clothing, tie back long hair, and stay alert around the

generator to prevent injury from moving parts.

Read the instructions before you begin, and make sure you have the tools and skills required.

Your authorized service center knows your generator best and is fully equipped to do maintenance and repair.

To ensure the best quality and reliability, use only new genuine parts or their equivalents for repair or replacement.

CAUTION: To reduce the possibility of fire or explosion, be careful when working around gasoline.

Use only a nonflammable solvent, not gasoline, to clean parts. Keep smoking, sparks, and

flames away from all fuel-related parts.

MAINTENANCE SCHEDULE

NOTE: Initial oil change should performed after first 25 hours of use. Thereafter change oil every 50 hours.

Before changing oil, check for a suitable way to dispose of the old oil. Do not pour it down into

sewage drains, onto garden soil or into open streams, Your local zoning environmental regulations

will give you more detailed instructions on proper disposal.

Items marked with a 䡬 required advanced skill and tools, so they should be done by the authorized

HITACHI Service Center.

ENGINE OIL CHANGE

Change engine oil every 50 hours.

(for a new engine, change oil after 25 hours.)

1. Drain oil by removing the oil drain plug and the oil filler cap while the engine

is warm.

2. Reinstall the oil drain plug and fill the engine with oil unit it reaches the upper

level on the oil filler cap.

● Use fresh and high quality lubricating oil to the specified quantity.

If contaminated or deteriorated oil is used or the quantity of the engine oil

is not sufficient, the engine damage will result and its life will be greatly

shortened.

OIL

Wash your hands with soap and water after handling used oil.

Please dispose of used motor oil and containers in a manner that will not harm the natural environment. We

suggest you take it in a sealed container to your local service station or recycling center for reclamation. Do not

throw it in the trash, pour it on the ground or down the drain.

NOTE: Never operate the generator without oil cap tightly secured. Failure to do so could cause oil to spill

out of the engine.

AIR FILTER

Adirty air cleaner will restrict airflow to the carburetor. To prevent carburetor malfunction, service the air filter

regularly. Service more frequently when operating the generator in extremely dusty areas.

NOTE: Never run the generator without the air cleaner. Rapid engine wear will result.

1. Take out the air cleaner, clean it well in kerosene and dry it.

2. After wetting the element by clean engine oil, squeeze it tight by hand.

3. Lastly, put the element in the case and install it securely.

SPARK PLUG SERVICE

To service the spark plug, use plug wrench (standard accessory). Use

recommended spark plugs.

RECOMMENDED PLUG AND ELECTRODE CLEARANCE

To ensure proper engine operation, the spark plug must be properly gapped and

free of deposits.

CAUTION: If the engine has been running, the muffler will be very hot.

Be careful not to touch the muffler. Be sure to allow the

engine to cool before you touch the spark plug.

1. Remove the spark plug cap.

2. Clean any dirt from around the spark plug base.

3. Use a spark plug wrench to remove the spark plug.

4. Visually inspect the spark plug. Replace it if the insulator is cracked or

chipped.

Clean the spark plug with a wire brush if you plan to reuse it.

5. Measure the plug gap with the feeler gauge. Correct as necessary by carefully bending the side electrode

(Fig.29).

6. Check that the spark plug washer is in good condition. If it is not, thread the spark plug in by hand to prevent

cross threading.

7. After the spark plug is seated, tighten with a spark plug wrench to compress the washer. If you are installing a

new spark plug, tighten the spark plug 1/2 turn after it seats to compress the washer. If you are reinstalling a

used spark plug, tighten 1/8–1/4 turn after the spark plug seats to compress the washer.

NOTE: The spark plug must be securely tightened. An improperly tightened spark plug can become very

hot and could damage the engine. Never use spark plugs which have an improper heat range. Use

only the recommended spark plugs or equivalent.

drain the fuel completely.

3. Change engine oil.

4. Check for loose bolts and screws, tighten them if necessary.

5. Clean generator thoroughly with oiled cloth. Spray with preservative if

available.

NEVER USE WATER TO CLEAN GENERATOR!

6. Pull starter handle until resistance is felt, leaving handle in that position.

7. Store generator in a well ventilated, low humidity area.
