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.

Application and Power Requirements
This generator is designed to operate single-phase, 50 Hz appliances
running at 230 VAC.
CAUTION: Do not exceed the power output of the generator. Damage
to tools or generator will occur. See Technical Data.
Check the nameplate or label provided on tools and appliances to
make sure their power requirements are met by the power output of the
generator. If the wattage is not given for a particular tool or appliance,
contact the tool manufacturer for wattage requirements.
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 determine power
requirements for different types of equipment. Check with your nearest
Wacker dealer, or contact the manufacturer or dealer of the tool or
appliance, if you have questions regarding power requirements.
CAUTION: DO NOT exceed the rated current limit of any receptacle.
CAUTION: If a tool or appliance does not reach full speed within a few
seconds after it is 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:
VOLTS x AMPS = WATTS

Indoor Installation
DANGER
4.3
G 3.3A
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.
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 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 generator, and using only electrical cables in good condition,
must be observed. See Operating Safety.
Outdoor Installation
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 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.

G 3.3A
Generator Derating
All generators are subject to derating for altitude and temperature.
Internal combustion engines, unless modified, run less efficiently at
higher altitudes due to the lack 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 the 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.

Use of Extension Cords
WARNING
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 cord with a larger cross section will reduce the voltage
loss.
CAUTION: Operating equipment at low voltage can cause it to
overheat.
Use the table as a guide for selecting proper cable size.
Use only tough rubber-sheathed cable in accordance with IEC 245-4.
Damaged cords can cause electrical shock. Electric shock can cause
serious injury or death. DO NOT use worn, bare, or frayed cords.
Replace damaged cords immediately.
