Instruction manual
WARNING! During the use of certain
gasoline tools, some dust containing
chemicals known to cause cancer,
may occur.
Some of these chemicals are: lead from lead based
paints, crystalline silica from bricks and cement and
other masonry products, arsenic and chromium from
chemically treated lumber and other dangerous
products. If dust is present, your risk from these
exposures varies, depending on how often you do this
type of work.
To reduce your exposure to these chemicals, any
time you do pulverulent operations, work in a well
ventilated area and work with approved safety
equipment, such as dust masks that are specially
designed to lter out microscopic particles.
∙If the machine strikes a foreign body, examine the
device for signs of damage and carry out any necessary
repairs before restarting and continuing to work.
∙If the machine starts to vibrate abnormally, switch
off the motor and check for the cause immediately.
Vibration is generally a warning of trouble.
∙Always turn off the machine and wait until the
machine completely stops whenever you leave
the machine, before carrying out maintenance,
before changing accessories, checking, cleaning,
troubleshooting or working on the machine.
∙It is forbidden to move or modify any of the internal
parts of the machine.

OPERATING INSTRUCTIONS
Connections to a building’s electrical system
Connections for standby power to a building’s electrical
system must be made by a qualied electrician. The
connection must isolate the generator power from utility
power, and must comply with all applicable laws and
electrical codes.
WARNING! Improper connections
to a building’s electrical system can
allow electrical current from the
generator to backfeed into the utility
lines. Such backfeed may electrocute
utility company workers or others
who contact the lines during a power
outage. When utility power is restored,
the generator may explode, burn, or
cause res in the building’s electrical
system. Consult the utility company
or a qualied electrician.
In some areas, generators are required by law to be
registered with local utility companies. Check local
regulations for proper registration and use procedures.
Generator ground system
IVT gasoline generators have a system ground that
connects generator frame components to the ground
terminals (5) in the AC output receptacles (1). The

17
EN
Instruction manual
system ground is not connected to the AC neutral wire.
Local regulations, codes or laws may require that the
ground system be connected to the AC neutral wire.
If the generator is tested by a receptacle tester, it will
not show the same ground circuit condition as a home
receptacle.
If local regulations, codes, or laws require the system
ground to be connected to the AC neutral wire, consult a
qualied electrician or electrical inspector.
The ground terminal (5) can be used to ground the
generator or bond the frame of the generator to the
frame of a vehicle, but only if it is required by local law
or electrical code. Before using the ground terminal
consult a qualied electrical inspector for regulations in
your area.
AC applications
Before connecting an appliance or power cord to the
generator:
∙Make sure that it is in good working order. Faulty
appliances or power cords can create a potential for
electrical shock.
∙If an appliance begins to operate abnormally,
becomes sluggish or stops suddenly, turn it off
immediately. Disconnect the appliance and determine
whether the problem is and if the appliance, or if the rated
load capacity of the generator has been exceeded.
∙Make sure that the electrical rating of the tool or
appliance does not exceed that of the generator, Never
exceed the maximum power rating of the generator.
Power levels between rated and maximum may be used
for no more than 5 minutes.
NOTICE: substantial overloading will open the circuit
breaker. Exceeding the time limit for maximum power
operation or slightly overloading the generator may
not switch the circuit breaker OFF, but will shorten
the service life of the generator.
Limit operation requiring maximum power to < 30
minutes.
∙For continuous operation, do not exceed the rated
power.
∙In either case, the total power requirements (W)
of all appliances connected must be considered. Pay
attention to the power factor of your load. Always
calculate the absorption of the load to be applied to the
generator beforehand. For the generator’s power, refer
to the technical data label.
∙For the power of the connected appliances, refer to the
power consumption indicated on their technical data labels.
Appliance and power tool manufacturers usually list rating
information near the model number or serial number.
AC Operation
1. Start the engine.
2. Switch ON the AC circuit breaker (6).
3. Plug in the appliance.
Most motorized appliances require more than their
rated wattage for startup.
Do not exceed the current limit specied for any one
receptacle. If an overloaded circuit causes the AC circuit
breaker to switch OFF, reduce the electrical load on the
circuit, wait a few minutes and then reset the AC circuit
breaker (6).
DC Operation
The DC terminals may ONLY be used for charging 12
volt automotive-type batteries.
Connecting the battery cables:
1. Before connecting charging cable to a battery
that is installed in a vehicle, disconnect the vehicle’s
grounded battery cable.
WARNING! The battery gives off
explosive gases; keep sparks, ames
and cigarettes away. Provide adequate
ventilation when charging or using
batteries.
2. Connect the charging cable plug to the DC output
terminal (4) on the generator.
3. Connect the red clamp to the positive (+) battery
terminal.
4. Connect the black clamp to the negative (-) battery
terminal. Prevent the cable clamps from touching each
other. This will lead to the short circuit and may damage
the battery.
5. Start the generator.
NOTICE: do not start the vehicle while the battery
charging cables are connected and the generator is
running. The vehicle or the generator may be damaged.
Disconnecting the battery cables:
1. Stop the engine.
2. Disconnect the black clamp from the negative (-)
battery terminal.
3. Disconnect the the red clamp from the positive (+)
