AIR INDEX
Descriptive Term Applicable to Emissions Durability Period
Moderate - 50 hours (engine from 0 to 80 cc)
125 hours (engine greater than 80 cc)
Intermediate - 125 hours (engine from 0 to 80 cc)
250 hours (engine greater than 80 cc)
Extended - 300 hours (engine from 0 to 80 cc)

WARNING :
The engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.
To show compliance with California emission regulations, a hangtag has been provided
displaying the Air Index level and durability period of this engine.
The Air Index level defines how clean an engine’s exhaust is over a period of time. A bar
graph scaled from “0” (most clean) to “10” (least clean) is used to show an engine’s Air Index
level. A lower Air Index level represents cleaner exhaust from an engine.
The period of time (in hours) that the Air Index level is measured is known as the durability
period. Depending on the size of the engine, a selection of time periods can be used to
measure the Air Index level (see below).
Notice : This hangtag must remain on this engine or piece of equipment, and only be
removed by the ultimate purchaser before operation.
Notice : FEDERAL EMISSION COMPONENT DEFECT WARRANTY and CALIFORNIA EMISSION CONTROL
WARRANTY are applicable to only those engines/ generators complied with EPA (Environmental
Protection Agency) and CARB (California Air Resources Board) emission regulations in the U.S.A.
Notice : To the engines/generators exported to and used in the countries other than the U.S.A., warranty service
shall be performed by the distributor in each country in accordance with the standard engine/generator
warranty policy as applicable.
(California Proposition 65)

1. SAFETY PRECAUTIONS
−1−
ENGLISH
Please make sure you review each precaution carefully.
Do not operate the generator near gasoline or gaseous fuel because of the
potential danger of explosion or fire.
Do not fill the fuel tank with fuel while the engine is running. Do not smoke or
use open flame near the fuel tank. Be careful not to spill fuel during refueling.
If fuel is spilt, wipe it off and let dry before starting the engine.
WARNING
WARNING
Do not place in flammables near the generator.
Be careful not to place fuel, matches, gunpowder, oily cloths, straw, trash, or any other in flammables
near the generator.
WARNING
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.
If generator has been covered to protect it from the weather during non use, be sure to remove it and
keep it well away from the area during generator use.
WARNING
1m
1m
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.
WARNING
Pay attention to the wiring or extension cords 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, generator burnout, or electric shock hazard.
Replace damaged or worn cords immediately.
WARNING
Do not operate the generator inside a room, cave, tunnel, or other
insufficiently ventilated area.
Always operate it in a well-ventilated area, otherwise the engine may
become overheated, and the poisonous carbon monoxide gas, an
odorless, colorless, poison gas, contained in the exhaust gas will
endanger human lives.
Operate generator only outdoors and far from open windows, doors,
ventilation intakes and other openings.
Keep the generator at least 1 meter (3 feet) away , including overhead,
from any structure or building use.
EG781AEceGU683710.1.251:36PMページ1

−2−
Do not contact the generator to a commercial power line. Connection to a commercial
power line may short circuit the generator and ruin it or cause electric shock hazard.
Use the transfer switch for connecting to domestic circuit.
WARNING
Engine becomes extremely hot during and for some time after operation.
Keep combustible materials well away from generator area.
Be very careful not to touch any parts of the hot engine especially the muffler area
or serious burns may result.
WARNING
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
Do not operate in rain, in wet or damp conditions, or with wet hands.
The operator may suffer severe electric shock if the generator is wet due to rain or snow.
WARNING
Keep children and all bystanders at a safe distance from work areas.
WARNING
If wet, wipe and dry it well before starting. Do not pour water directly over the generator, nor wash it
with water.
WARNING
Be extremely careful that all necessary electrical grounding procedures are followed during each and
every use. Failure to do so can be fatal.
WARNING
It is absolutely essential that you know the safe and proper use of the power tool or appliance that
you intend to use. All operators must read, understand and follow the tool/appliance owners manual.
Tool and appliance applications and limitations must be understood. Follow all directions given on
labels and warnings. Keep all instruction manuals and literature in a safe place for future reference.
WARNING
Use only "LISTED" extension cords.
When a tool or appliance is used outdoors, use only extension cords marked "For Outdoor Use".
Extension cords, when not in use should be stored in a dry and well ventilated area.
WARNING
Always switch off generator's AC circuit breaker and disconnect tools or appliances when not in use,
before servicing, adjusting, or installing accessories and attachments.
WARNING
CAUTION
Make sure the engine is stopped before starting any maintenance, servicing or repair.
Make sure maintenance and repair of the generator set are performed by properly trained personnel only.

CHECK ENGINE OIL
Before checking or refilling oil, be sure
generator is located on stable and level
surface with engine stopped.
■Remove oil filler cap and check the
engine oil level.
■If oil level is below the lower level line,
refill with suitable oil (see table) to
upper level line. Do not screw in the
oil filler cap when checking oil level.
■Change oil if contaminated.
(See "How-To" Maintenance.)
Recommended engine oil :
Use 4-stroke automotive detergent oil
of API service class SE or higher grade
(SG, SH or SJ is recommended). SAE
10W-30 or 10W-40 is recommended
for general, all-temperature use. If
single viscosity oil is used, select the
appropriate viscosity for the average

GROUNDING THE
GENERATOR
■To ground the generator to the earth,
connect the grounding lug of the
generator to the grounding spike
driven into the earth or to the
conductor which has been already
grounded to the earth.
■If such grounding conductor or
grounding electrode is unavailable,
connect the grounding lug of the
generator to the grounding terminal of
the using electric tool or appliance.
Grounding spike
Death, personal injury and/or property damage may occur unless
instructions are followed carefully.
■Use battery of recommended capacity.
■Turn the starter switch to the "STOP" position when mounting or
dismounting battery. When mounting battery, connect the positive (+)
cable first and then the negative (
- ) cable to the battery. Be careful not to
short battery cables. When dismounting battery, disconnect negative (
- )
cable first.
RED CABLE : To positive (+) terminal
BLACK CABLE : To negative (
- ) terminal
■Should the connection be made in incorrect manner, the generator will
be broken.
