1. SAFETY PRECAUTIONS  
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.  
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.  
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  
3 feet  
the exhaust gases will endanger  
human lives. Keep the generator at  
least 3 feet (1 meter) away from any  
structure or building during use.  
(
)
3 feet 1m  
(
)
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.  
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.  
1-  
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.  
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.  
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.  
If wet, wipe and dry it well before starting. Do not pour water directly over the  
generator, nor wash it with water.  
Be extremely careful that all necessary electrical grounding procedures are  
followed during each and every use. Failure to do so can be fatal.  
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.  
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.  
2-  
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.  
Keep children and all bystanders at a safe distance from work areas.  
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.  
Notes on installation  
1. Select a place which allows you to maintain and inspect the generator, which is  
not exposed to contamination caused by exhaust gas.  
If you are planning to install the generator without its wheels attached, consider  
the work efficiency in terms of an oil change.  
2. In ground connection, be sure to use the designated ground terminal.  
(A grounding cable is not included in the set of accessories.)  
3. During use, be sure not to disconnect the battery.  
4. While the power is on, do not unplug the unit or disconnect cables from the  
terminals.

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 9,000 watt generator can power a 3,200 to 7,000  
watt electrical tool.)  
Loads such as submersible pumps, air conditioners 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 1,800 to 3,100 watt pump.)  
If the power consumption of electrical appliances exceeds the operating range  
or if there is short circuit or other problems in the appliances, the AC breaker  
could trip "OFF" or the rotation of the generator could be abnormally reduced.  
In this case, stop the generator to see if the power consumption of the  
appliances is too large and if there is a problem in the appliances.  
The frequency (the number of the generators rotation) was adjusted before the  
time of shipment. Changing the frequency could result in the generators  
breakdown, so refrain from changing it.  
21-  
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.

NOTE :  
The above wattage chart is general guide only. Refer to your specific  
appliance for correct wattage.  
When you use two or more alternating current outlets at a time, be careful that  
the sum of the appliances' power consumption does not exceed the value  
specified in the above chart.  
VOLTAGE DROP IN ELECTRIC EXTENSION CORDS  
When a long electric extension cord is used to connect an appliance or tool with  
the generator, a certain amount of voltage drop occurs in the extension cord which  
lessens the effective voltage available to the appliance or tool.  
The chart below has been prepared to illustrate the approximate voltage loss when  
an extension cord of 300 feet (approx. 100 meters) is used to connect an  
appliance or tool to the generator.
