Check engine oil level. Oil shall not be mixed with
gasoline, however, adequate oil supply is necessary for
the lubrication of the engine. Refer to the engine manual
for the oil type and quantity specications.
THE UNIT IS SHIPPED WITHOUT OIL IN THE ENGINE.
It is strongly recommended the use of a ground fault
interrupter (GFI). Ground fault circuit breakers can
signicantly reduce the possibility of injury if a short circuit
occurs. To install a GFI, the neutral wire of the welder/
generator must be internally grounded to the frame of
the welder/generator, and the frame must be properly
grounded.
OPERATION OF THE EARTH INTERRUPTER WILL
NOT BE EFFECTIVE IF THE WELDER/GENERATOR
IS NOT PROPERLY CONNECTED TO EARTH.
REFER TO THE SECTION TITLED GROUNDING FOR
APPROPRIATE STEPS TO GROUND YOUR WELDER/
GENERATOR
When installing a GFI, be sure to comply with all national
and local regulations. If you are not sure about the
regulations or procedures, obtain assistance from a
qualied electrician.
LUBRICATION
Do not attempt to start this engine without lling the
crankcase with the amount and type of suitable oil. (Use
SAE 10W-30). Your unit has been shipped from the
factory without oil in the crankcase. Operating the unit
without oil can ruin the engine.
Fill the engine with oil according to the engine manual.
In this engine, the plastic cap on the casing contains a
bayonet with marks of full and empty.

THE LOW OIL LEVEL SENSOR
This unit is equipped with an oil low level sensor. Initially, if
the oil level is lower than the required, sensor will activate
a protective device to stop the engine. (See the attached
engine manual for more information).
If unit shuts off and the oil level is within specifications,
check that the unit is not positioned at an angle that forces
oil to vary its level. Place it on an even surface to correct
this problem. If the engine does not start, oil level could
be not sufficient to deactivate low oil level switch. Make
sure that the oil plug mark is at correct level.
FUEL
Fill the tank with unleaded gasoline for cars, clean, fresh.
You can use regular grade gasoline provided than it is
high octane rating (at least 90 octane). We recommend
that you always use a gasoline additive. A gasoline
additive will minimize the formation of fuel gum deposits
during storage. Gasoline additive can be added to the
gasoline in the tank or added to the fuel or gasoline in a
storage container.
Fuel and engine smoke are flammable, and potentially
explosive. Use an appropriate procedure to store and
handle fuel. Always maintain ABC fire extinguishers on
hand.
CAUTION
Do not overfill the tank. Maintain a maximum
level of fuel to 1/4 inch below the top of the
fuel tank. This will allow expansion in hot
weather, thus avoiding spillage.

HOW TO DETERMINE THE POWER
VOLTAGE REQUIREMENT
All engine exhaust contains carbon monoxide,
a deadly gas. Breathing carbon monoxide can
cause headache, dizziness, nausea, confusion
and eventually death. Carbon monoxide is deadly,
odorless and invisible gas, and it can be present even
though you cannot see or smell it. Deadly levels of carbon
monoxide can be accumulated quickly, and you may lose
ability to save yourself. Also, deadly levels of carbon
monoxide can be stored for hours or days in closed or
poorly ventilated areas. If you experience any symptoms
of poisoning, get fresh air and seek for medical help. To
prevent serious injury or death by carbon monoxide:
NEVER operate engine indoors. Although the case of
having ventilating fans, windows or open doors, carbon
monoxide can quickly reach dangerous levels.
NEVER turn on engines in areas poorly ventilated or
partially closed. Areas such as warehouses, garages,
basements, homes, rooms, etc.
NEVER turn on engines when the engine exhaust gases
may go into buildings through openings such as windows
or doors.
In order to prevent overloading and possible damage to
your generator, it is necessary to know the total power
of the connected load. To determine which tools and/or
appliances your generator will run, follow the steps below:
Determine if you want to operate a device or multiple
devices simultaneously.
Verify start and function power of the apparatuses to
be connected to the generator by checking the power
required in the product label or have help using the values
of table 1 or by calculations (multiply amps x volts).
Summarize all the start and function powers. If label gives
only the voltage and amperage, multiply volts x amp =
watts. 1kW = 1,000 watts.
During starting the motor-driven appliances or tools
require more power than what is specified on its
nameplate. Note: Consider 2 ½ - 4 times the power
marked on the nameplate for start.
The welder/generator’s rated watts shall match or exceed
the number of watts required by all the apparatuses you
want to be supplied by the generator.
The continuous generator power decreases according to
the temperature and altitude of the place where you are
using the equipment. Use the power correction table and
multiply the rated power indicated in the specicatrion
shhet by the correction factor.
Always connect the bigger load rst, and then add the
other apparatuses one by one.
You must use a conditioner (regulator) line when one
or more of the following solid state equipment will be
connected to the generator:
• Control for garage door openers.
• Kitchen appliances with digital displays.
• Televisions.
• Stereo.
• Personal computers.
• Quartz watches.
• Photocopy machines.
• Telephone equipment

Refer to the nameplate on the welder/generator for the power
and amperage ratings.
Note: The required power can be calculated by multiplying the
volts and the amperes. The resulting number is the power in
watts.
Always switch off and remove the electric load before turn on or
off the welder/generator engine.
Refer to the table for minimum sizes of extension cord in
accordance with the needs of loads.
When the load increases you must use an extension cord of
bigger size. Use of inappropriateAWG size extensions can cause
serious problems with voltage, resulting in a loss of energy and
damage of the tools.
The smaller the AWG number is, the higher the conductor
amperage. A 14 AWG conductor, for example, can carry out a
current higher than that corresponding to a 16 AWG one.
When there are connected multiple extensions it must checked
that each extension is of the minimum recommended cable size.
If an extension is used with outputs for more than one apparatus
sum the amperes of the nameplate of each one of the devices
to determine the minimum extension cord size.
The extensions for 120 V outputs shall be 3-wire ones, where the
green wire is the ground wire, the white or gray lead is connected
to the neutral of generator, and the black wire is the hot wire.
Extensions for 125/250 outputs shall be 4-wire ones, where the
green wire is the ground wire, the white or gray lead is connected
to the neutral of generator, and black and red wires are the hot
wires.
If not load real watts are known, table 1 can be used as
a general guide.
Remember that apparatuses which generate heat during
operation such as heaters, incandescent lamps, motors
and hair dryers, require a power higher than devices that
generate little heat during operation such as uorescent
lamps, radios and clocks.
Power cords and extension cords may require additional
power depending of the cord length . Keep cords of
the smaller possible length. See tables 3 and 4 for
the recommended extension cords size and length
depending on the amperage or wattage.
The circuit protection is provided by two OPS (thermal
breaker) that opens when the welder/generator load
exceeds its maximum capacity or a short circuit occurs.
If the OPS is activated, use the following procedure to
correct the problem:
a. turn off and unplug all electrical load.
b. try to determine the cause of the electrical problem -
overload or short circuit.
c. do not use any device that has a short circuit. Avoid
overloading the welder/generator
d. press the OPS button to reset it.
A REPEATED OPERATION OF THE OVERLOAD
PROTECTOR INDICATES A PROBLEM AND
CAN CAUSE DAMAGE TO THE PRODUCT OR
ELECTRICAL DEVICES. DO NOT OPERATE THE
