WARNING
Generator exhaust contains carbon monoxide, a
poisonous gas that can kill you.
You CANNOT smell or see this gas.
• Use the generator outdoors, away from open windows, vents, or
doors that could allow the carbon monoxide gas to come indoors.
Keep the generator at least 1 meter (3 feet) away from any structure
or building during use.
• NEVER use a generator indoors, including in homes, garages,
basements, crawl spaces, and other enclosed or partially-enclosed
areas, even with ventilation. Opening doors and windows or using
fans will not prevent carbon monoxide build-up in the home.
• NEVER use a generator in enclosed or partially-enclosed spaces.
Generators can produce high levels of carbon monoxide very quickly.
When you use a portable generator, remember that you cannot smell
or see carbon monoxide. Even if you can’t smell exhaust fumes, you
may still be exposed to carbon monoxide.
• NEVER operate the generator in an explosive atmosphere, near
combustible materials or where ventilation is not sufficient to carry
away exhaust fumes. Exhaust fumes can cause serious injury or death.
• If you start to feel sick, dizzy, or weak while using a generator, get
to fresh air RIGHT AWAY. DO NOT DELAY. The carbon monoxide
from generators can rapidly lead to full incapacitation and death.
• If you experience serious symptoms, get medical attention
immediately. Inform medical staff that carbon monoxide poisoning
is suspected. If you experienced symptoms while indoors, have
someone call the fire department to determine when it is safe to
re-enter the building.
SAFETY

WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or death.
When Adding or Draining Fuel
• Observe all safety regulations for the safe handling of fuel. Handle
fuel in safety containers. If the container does not have a spout, use
a funnel.
• Do not overfill the fuel tank. Leave room for the fuel to expand.
• Do not refill fuel tank while the engine is running. Before refueling the
generator, turn it off and let it cool down. Gasoline spilled on hot
engine parts could ignite.
• Fill the tank only on an area of bare ground. While fueling the tank,
keep heat, sparks and open flame away. Carefully clean up any spilled
fuel before starting engine.
• Always fill fuel tank in an area with plenty of ventilation to avoid
inhaling dangerous fumes.
• NEVER store fuel for your generator in the home. Gasoline, propane,
kerosene, and other flammable liquids should be stored outside of
living areas in properly-labeled, non-glass safety containers. Do not
store them near a fuel-burning appliance, such as a natural gas water
heater in a garage. If the fuel is spilled or the container is not sealed
properly, invisible vapors from the fuel can travel along the ground and
can be ignited by the appliance’s pilot light or by arcing from electric
switches in the appliance.
SAFETY

WARNING
The GFCI may not function unless the generator is properly
grounded. Follow the correct procedure specified in the section
labeled GROUNDING INSTRUCTIONS.
Ground Fault Circuit Interrupter Protection
These generators are equipped with a GFCI (Ground Fault Circuit
Interrupters) 120V duplex receptacles for protection against the hazards
of electrical shock from defective attachments such as, tools, cords,
and cables.
A GFCI is a device that interrupts electricity from either the utility or
generator by means of a special type of circuit breaker that determines if a
current flow to the ground occurs.
A GFCI can be used only with generators that have the neutral wire
internally bonded to the frame, and the frame properly grounded to the
earth. A GFCI will not work on generators that do not have the neutral
wire bonded to the frame, or on generators which have not been properly
grounded. All of our generators have internally bonded ground wires.
THERE IS A PERMANENT CONDUCTOR BETWEEN THE
GENERATOR (STATOR WINDING) AND THE FRAME.
SAFETY

10
DANGER
Improper grounding can result in a risk of electrocution.
Check with a qualified electrician for your local
requirements if you are in doubt as to whether the unit is
properly grounded.
This generator is equipped with a grounding terminal for added
protection. Using the ground path from the generator to an
external ground source as instructed in the section labeled “Grounding
Instructions” in the Preparation section of this manual can be
necessary. Please consult a qualified electrician for local regulations.
The generator is a potential source of electrical shock if not kept dry.
Keep the generator dry and do not use in rain or wet conditions. To
protect from moisture, operate it on a dry surface under an open,
canopy-like structure. Dry your hands if wet before touching the
generator.
Plug appliances directly into the generator. Or, use a heavy duty,
outdoor-rated extension cord that is rated (in watts or amps) at least
equal to the sum of the connected appliance loads. Check that the
entire cord is free of cuts or tears and that the plug has all three
prongs,especially a grounding pin.
NEVER try to power the house wiring by plugging the generator into
a wall outlet, a practice known as “back feeding”. This is an extremely
dangerous practice that presents an electrocution risk to utility workers
and neighbors served by the same utility transformer. It also bypasses
some of the built-in household circuit protection devices.
If you must connect the generator to the house wiring to power
appliances, have a qualified electrician install the appropriate
equipment in accordance with local electrical codes.
This product has been designed with internal grounding or floating bonded
neutral. If it should malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of electric shock.
SAFETY

11
• Do not enclose the generator or cover it. The generator 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 a level area is recommended.
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
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 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. 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.
• DO NOT smoke while charging a 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 charging a battery.
Important Safety Instructions
WARNING
To reduce the risk of injury, read this operator’s manual
completely before using.

precautions should always be followed.
SAFETY

12
• The 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.
• Keep children and all bystanders at a safe distance from work area.
• 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.
NOTE: Make sure maintenance and repair of the generator are performed
by properly trained personnel only.

Grounding Instructions
The ground terminal on the frame can be used to connect the generator
to a suitable ground source. The ground path should be made with #8 size
wire. Connect the grounding wire securely to the ground terminal. Connect
the other end of the wire securely to a suitable ground source.
A metal underground water pipe in direct contact with the earth for at
least 10 feet can be used as a grounding source. If a pipe is unavailable,
an 8 foot length of pipe or rod may be used as the ground source. The
pipe should be 3/4” diameter or larger and the outer surface must be
noncorrosive. If a steel or iron rod is used it should be at least 5/8”
diameter and if a nonferrous rod is used it should be at least 1/2” diameter
and be listed as material for grounding. Drive the rod or pipe to a depth of
8’. If a rock bottom is encountered less than 4’ down, bury the rod or pipe
in a trench. All electrical tools and appliances operated from this generator
must be properly grounded by use of a third wire or be “Double Insulated”.
It is recommended to:
1. Use electrical devices with 3 prong power cords.
2. Use an extension cord with a 3 hole receptacle and a 3 prong plug at
the opposite ends to ensure continuity of the ground protection from
the generator to appliance.
We strongly recommend that all applicable regulations relating to
grounding specifications be checked and followed.
DANGER
Improper connection of the equipment grounding
conductor can result in a risk of electrocution.
Check with a qualified electrician if you are in doubt as to whether the
unit is properly grounded for your local regulations.
