DANGER
CARBON MONOXIDE
Using a generator indoors CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide (CO). This is a poison you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
• NEVER use a generator inside homes, garages, crawlspaces, or other partly enclosed areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply enough fresh air.
• ONLY use a generator outside and far away from windows, doors, and vents. These openings can pull in generator exhaust.
Even when you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-backup CO alarm in the home.
If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh air RIGHT AWAY. See a doctor. You could have carbon monoxide poison.

Determining Power Requirements
This generator is designed to operate single-phase, 60 Hz appliances running at 120 VAC or 240 VAC. Check the nameplate or label provided on tools and appliances to make sure their power requirements match the power output of the generator.
Some appliances and tools require a surge of current when starting.
This means that the amount of power needed to initially start the equipment is larger than the power required to keep it running. The generator must be capable of supplying this “surge” current. Other types of appliances require more power than is actually stated on their nameplate.
The information in “Approximate Starting Power Requirements” is offered only as a general guideline to help you in determining power requirements for different types of equipment. Check with your nearest
Wacker Dealer, or contact the manufacturer or dealer of the tool or appliance, with questions regarding its power requirements.
CAUTION: If a tool or appliance does not reach full speed within a few seconds when switched on, turn it off immediately to avoid damage.
Approximate Starting Power Requirements
• Incandescent lights and appliances such as irons and hot plates, which use a resistive-type heating element, require the same wattage to start and run as is stated on their nameplates.
• Fluorescent and mercury lamps require 1.2–2 times their stated wattage to start.
• Electrical motors and many types of electrical tools often require a large starting current. The amount of starting current depends on the type of motor and its use.
• Most electrical tools require 1.2–3 times their stated wattage for starting.
• Loads such as submersible pumps and air compressors require a very large force to start. They need as much as 3–5 times the wattage stated on the nameplate in order to start.
If the wattage is not given for a particular tool or appliance, it can be calculated by multiplying its voltage and amperage requirements:
Single Phase: VOLTS x AMPS = WATTS
Three Phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS wc_tx000152gb.fm

G/GS 5.6A
4.2
Outdoor Installation
Operation
Place the generator in an area where it will not be exposed to rain, snow, or direct sunlight. Make sure it is positioned on firm, level ground, so it will not slide or shift. Position the engine exhaust away from areas where people may be present.
If operating the generator inside a tunnel or deep trench, make sure there is adequate ventilation. Precautions similar to those required when operating indoors may be necessary.
The surrounding area must be free from water and moisture. All components must be protected from excessive moisture.
4.3
Indoor Installation
If the generator must be installed indoors, adequate ventilation or exhaust hoses must be provided. When venting exhaust fumes, make sure the exhaust piping is large enough to prevent excessive back pressure to the engine. Back pressure reduces engine efficiency and may cause the engine to overheat.
DANGER
Exhaust gas from the engine contains poisonous carbon monoxide gas; exposure to carbon monoxide can cause loss of consciousness and may lead to death. Never run the generator indoors or in an enclosed area unless adequate ventilation, through such items as exhaust hoses or fans, is provided.
When installed indoors, steps to prevent fire and explosion such as providing a good, earthen ground, removing all flammable materials near the generator, and using only electrical cables in good condition, must be observed. See Operating Safety.

G/GS 5.6A
4.6
Generator Derating
Operation
All generators are subject to derating for altitude and temperature.
Internal combustion engines, unless modified, run less efficiently at higher altitudes due to the reduction of air pressure. This translates into a lack of power and thus reduction in generator output.
Temperature affects both engine and generator performance. As temperature increases, an engine will run less efficiently and more resistance will be found in electrical components. Therefore, as the temperature increases, the output of the generator decreases. Altitude also affects the cooling capacity of air—the higher the altitude the less dense the air is and thus the lower its ability to transfer heat.
For every increase in altitude of 500 m (1650 ft.) above 1000 m (3300 ft.), the output of the generator will be reduced by 3%. For every increase of 5° C (9° F) in ambient temperature above 40° C (104° F), the output of the generator will be reduced by 3%. Use the tables shown for altitude and temperature deration factors. It may be necessary to consider both altitude and ambient temperature deration factors to determine true generator output.

When a long extension cord is used to connect an appliance or tool to the generator, a voltage loss occurs—the longer the cord, the greater the voltage loss. This results in less voltage being supplied to the appliance or tool and increases the amount of current draw or reduces performance. A heavier cord with a larger wire size will reduce the voltage loss.
WARNING
Damaged extension cords can cause electrical shock, resulting in serious injury or death. DO NOT use worn, bare, or frayed cords.
Replace damaged cords immediately.

Operation
See Graphic: wc_gr000545
The two 120V, 20 Amp receptacles (f) are protected by a ground fault circuit interrupt (GFI). The GFI shuts off the power to the receptacle when a ground fault occurs in the generator or to a piece of equipment attached to the generator.
The GFI should be tested for proper operation every time the generator is used.
To test GFI:
Start generator. Turn auto idle "OFF". Push TEST button (h) on receptacle in. The RESET button (g) will pop out. Power is now off at the receptacles. If the RESET button does not pop out, the GFI is not working. Do not run generator until the problem can be corrected. To restore power to receptacles, push the RESET button in.
If the RESET button pops out during operation, stop the generator and check generator and equipment for defects.

Operation
4.13 Engine Auto Idle
G/GS 5.6A
See Graphic: wc_gr000545
The auto idle switch (b) automatically reduces engine speed approximately 7 seconds after all appliances or tools attached to the generator have been turned off. The engine automatically returns to full speed when a tool or appliance is turned back on.
To turn the auto idle feature on, push the auto idle switch to “AUTO”.
The AUTO setting is recommended while the generator is running to minimize fuel consumption. To avoid extended engine warm-up periods, keep switch set to “OFF” when starting the engine and until the engine reaches operating temperature.
4.14 Engine Speed
Generators require a fixed engine speed to maintain the correct voltage. Engine speed is controlled by a governor which automatically adjusts to varying loads on the engine to maintain a constant speed.
See Technical Data. There is no throttle control. Use the Auto Idle switch on the generator to control engine speed.

4.15 Voltage Selection
Operation
See Graphic: wc_gr000546
The voltage selector switch (a) allows the generator to operate in either single (120V) or dual voltage (120/240V) mode.
In single voltage mode only the 120V twist-lock and duplex receptacles are powered. The full rated power of the generator is shared between the three receptacles.
In dual voltage mode both the 120V and 240V receptacles are powered; however, only half the rated power (23 amps) is available at the 120V duplex receptacles and the other half at the 120V twist-lock receptacle. Full power is available at the 240V twist-lock receptacle.
CAUTION: NEVER switch the voltage selector switch with the main breaker on! This can cause arcing and can damage the generator.
Turn all tools and appliances off and place main breaker in the “OFF” position (open) (O) before changing voltage switch position.
