1. SAFETY PRECAUTIONS

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.

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.

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.

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 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.

WARNING

SGX7500usGU7064.indd1

2010/07/2214:04:37

ENGLISHFRANÇAISEESPAÑOL

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.
