IMPORTANT SAFETY INSTRUCTIONS FOR USING GENERATORS

READ ALL OF THE WARNINGS AND OPERATING INSTRUCTIONS IN THIS MANUAL BEFORE OPERATING

OR MAINTAINING THIS GENERATOR:

WARNING: Read and understand all instructions. Familiarity and proper training are required for the

safe operation of generators. A generator operated improperly or by untrained personnel

can be dangerous. Become familiar with all of the generator's controls, output receptacles

and connections. Know how to stop generator in case of emergency. Failure to follow all

instructions listed below may result in electrical shock, property damage, and/or serious

personal injury or death. Do not operate the generator unless it is fully assembled.

WARNING: CARBON MONOXIDE HAZARDS

Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing

exhaust can cause loss of consciousness and may lead to death. If you run the generator

in an area that is conﬁned, or even partially enclosed the air you breathe could contain a

dangerous amount of exhaust gas. To keep exhaust from building up, provide adequate

ventilation. Do not operate the generator in a room, cave, or tunnel unless professionally

installed exhaust hoses are used.

SAFETY

IMPORTANT SAFETY INFORMATION

Read and understand all of the safety precautions, warnings and operating instructions in the Instruction Manual

before operating or maintaining this generator.

Most accidents that result from generator operation and maintenance are caused by the failure to observe basic

safety rules or precautions. An accident can often be avoided by recognizing a potentially hazardous situation

before it occurs, and by observing appropriate safety procedures.

Basic safety precautions are outlined in the ‘‘SAFETY’’ section of this Instruction Manual and in the sections, which

contain the operation and maintenance instructions.

Hazards that must be avoided to prevent bodily injury or machine damage are identiﬁed by WARNINGS on the

generator and in this Instruction Manual.

NEVER use this generator in a manner that has not been speciﬁcally recommended by HITACHI

MEANINGS OF SIGNAL WORDS

English

WARNING: ELECTRIC SHOCK HAZARDS

The generator produces enough electrical power to cause serious shock or electrocution if

misused. Using a generator or an electrical device in wet conditions — near water, on wet

grass, in damp areas, in rain or snow — could result in electrocution. Keep the generator

dry at all times.

This generator is not designed to be stored outdoors unprotected from the weather.

Moisture or ice can cause a malfunction or short in electrical components, which could

result in electrocution.

Check all electrical components on the control panel before each use. 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

11 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.

Never use generator for applications other than those speciﬁed in the Instruction Manual.

3. ALWAYS KEEP WORK AREA CLEAN.

Avoid injuries by not cluttering the work areas.

8. Do not place inﬂammables near the generator.

Be careful not to place fuel, matches, gunpowder, oily cloths, straw, trash, or any other inﬂammables near the

generator.

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.

14. Do not operate the generator under the following condition: rainwater, seawater and salty breezes.

If the generator is used under the above condition, it may break and the operator may suffer severe electric

shock.

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 better.

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

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

all-temperature use. Other viscosities shown in Fig.23 may be used when the

average temperature in your area is within the indicated range.

CHECKING THE OIL

Remove the oil maintenance cover and oil ﬁller cap and inspect if the engine oil

is at the upper level (standard level) on the oil level gauge.

If the level is low, supply new oil to the standard level.

NOTE: ● Tighten the oil ﬁller cap securely.

● Be sure to wipe off spilled engine oil.

● Use API classiﬁcation class SE or better SAE 5W or 5W-30 oil at cold

temperatures.

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

Remove the fuel tank cap and inspect the fuel level. If the fuel evel is low, supply

fuel so that the ﬁlling limit position (red level) is not exceeded. Refuel carefully to

avoid spilling fuel.

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.

●When disconnecting the cable from the battery,

disconnect the cable ﬁrst. On contrary, connect the

cable ﬁrst when connecting. If the order is wrong, a

short-circuit may be caused.

1. Remove the cables and tubes from the battery.

2. Measure the speciﬁc gravity of the battery electrolyte and determine the

charging time.

● Remove the electrolyte supply caps of the battery and check the

electrolyte level. If the level is low, supply distilled water to the upper limit.

● Measure the speciﬁc gravity of the battery electrolyte and determine the

charging time in the table on the right.

The speciﬁc gravity of a fully charged electrolyte is 1.26 to 1.28. The

charging time varies according to the type of the battery and discharge

conditions. Check every hour.

3. Connect the charging cable between the DC terminals and battery terminals.

CAUTION: ●Use the special charging cable (option) for connection

with the battery.

●Do not make a mistake in the and polarities when

connecting the charging cable. Wrong connection may

cause a short circuit or failure of the generator or battery.

4. Adjust the output selection switch of the generator to 950VA and start the

engine to start charging.

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:

Cause Remedy

● There is no fuel.

● The fuel pipe is clogged.

● The fuel strainer is clogged.

● The carburetor is clogged.

● The spark plug is dirty.

● The electrode gap of the spark plug

is incorrect.

● The engine oil is insufﬁcient.

● l Supply fuel.

● Clean the fuel pipe.

● Change the fuel strainer.

● Clean the carburetor.

● Clean the spark plug and dry it.

● Adjust the electrode gap to the

correct state.

● Supply engine oil.

Cause Remedy

● The AC or DC protector is turned

off.

● Turn on the AC and DC protectors.

● The total power consumption of

the connected electric appliances

exceeds the operating range of the

generator.

● Use only electric appliances so

that the power consumption is

contained in the operating range of

the generator.

● There is poor contact between the

plug and outlet.

● Securely insert the plug of the

electric appliance into the outlet.

• 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 20 hours of use. Thereafter change oil every 100

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.
