1. SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
WARNING
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
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 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 contained in the exhaust gases will endanger human lives.
Keep the generator at least 1 meter (3 feet) away from any structure or
1m
building during use.
1m
If the generator must be used indoors, the area must be well-ventilated and
extreme caution must be taken regarding the discharge of exhaust gases.
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
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.
－ 1－
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
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
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
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
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
Keep children and all bystanders 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 appliances when not in use,
before servicing, adjusting, or installing accessories and attachments.

6. WATTAGE INFORMATION
Some appliances need a "surge" of energy when starting.
This means that the amount of electrical power needed to start the appliance may exceed
the amount needed to maintain its use.
Electrical appliances and tools normally come with a label indicating voltage, cycles / Hz,
amperage (amps) and electrical power needed to run the appliance or tool.
Check with your nearest dealer or service center with questions regarding power surge of
certain appliances or power tools.
■
Electrical loads such as incandescent lamps and hot plates require the same wattage
to start as is needed to maintain use.
■
Loads such as fluorescent lamps require 1.2 to 2 times the indicated wattage during
start-up.
■
Loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.
■
Electrical motors require a large starting current. Power requirements depend on the
type of motor and its use. Once enough "surge" is attained to start the motor,
the appliance will require only 50% to 30% of the wattage to continue running.
■
Most electrical tools require 1.2 to 3 times their wattage for running under load during
use. For example, a 5,000 watt generator can power a 1800 to 4000 watt electrical
tool.
■
Loads such as submersible pumps and air compressors require a very large force to
start. They need 3 to 5 times the normal running wattage in order to start.
For example, a 5,000 watt generator would only be able to drive a 1,000 to 1,700 watt
pump.
NOTE :
The following wattage chart is general guide only. Refer to your specific appliance for
correct wattage.
To determine the total wattage required to run a particular electrical appliance or tool,
multiply the voltage figure of the appliance/tool by the amperage (amps) figure of same.
The voltage and amperage (amps) information can be found on a name plate which is
normally attached to electrical appliances and tools.

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS
When a long electric extension cord is used to connect an appliance or tool to the
generator, a certain amount of voltage drop or loss occurs in the extension cord
which reduces the effective voltage available for the appliance or tool.
The chart below has been prepared to illustrate the approximate voltage loss when
an extension cord of 100 meters is used to connect an appliance or tool to the
generator.
