WARNING :

The engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.

AIR INDEX

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).

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)

500 hours (engine greater than 80 cc)

1000 hours (225 cc and greater)

Notice : This hangtag must remain on this engine or piece of equipment, and only be
removed by the ultimate purchaser before operation.

Notice : There is permanent conductor between the generator (Stator Winding) and the frame.
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
warranty policy as applicable.

SAFETY PRECAUTIONS

Please make sure you review each precaution carefully.

DANGER

Do not operate the generator indoors, in a garage, carport, basement or other
confi ned space. Opening a garage door does not provide suffi cient ventilation to
prevent injury or death.

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 window, doors, ventilation
intakes and other openings.
Keep the generator at least 1 meter (3 feet) away, including overhead, from any
structure of building use.

WARNING

Do not operate the generator near gasoline or gaseous fuel because of the potential danger of
explosion or fi re.
Do not fi ll the fuel tank with fuel while the engine is running. Do not smoke or use open fl ame near
the fuel tank. Be careful not to spill fuel
during refueling. If fuel is spilled, wipe it off and let dry before starting the engine.

WARNING

Do not place fl ammables near the generator.
Be careful not to place fuel, matches, gunpowder, oily cloths, straw, trash, or any other
fl ammables 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.

ENGLISHFRANÇAISEESPAÑOL

WARNING

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 fi re, generator
burnout or electric shock hazard. Replace damaged or worn cords immediately.

WARNING

Do not operate in rain, 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

If wet, wipe and dry it well before starting, Do not pour water directly over the generator, nor wash it with water.

SGX3500-7500OMceGU7719.indd2 2014/08/2311:11:04

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

Do not connect 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

ENGLISHFRANÇAISEESPAÑOL

connecting to domestic circuit.

WARNING

No smoking while handling the battery. The battery emits fl ammable hydrogen gas, which can explode if
exposed to electric arcing or open fl ame. Keep the area well-ventilated and keep open fl anges/sparks
away when handling the battery.

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
muffl er area or serious burns may result.

WARNING

Keep children and all bystander at a safe distance from work areas.

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 appliance when not in use, before servicing,
adjusting, or installing accessories and attachments.

WARNING

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.

WARNING

Do not allow drunk driving.

WARNING

Do not use the generator as electric power for medical appliance.

CAUTION

Warning labels are affi xed to our engines with regard to particularly serious dangers.
