Equipment), are certified to operate on regular unleaded gasoline, and may include the following
emission control systems: (EM) Engine Modifications and (TWC) Three-Way Catalyst (if so
equipped).
GENERAL SAFETY PROCEDURES
Please familiarize yourself with the following safety symbols and words:
The safety alert symbol ,/k is used with one of the safety words (DANGER, CAUTION, or
WARNING) to alert user to hazards. Please pay attention to these hazard notices both in this manual
and on the generator.
DANGER: Indicates a hazard that will result in serious injury or death if instructions are not followed.
WARNING: Indicates a strong possibility of causing serious injury or death if instructions are not
followed.
CAUTION: Indicates a possibility of personal injury or equipment damage if instructions are not
followed.
If you have any questions regarding the hazard and safety notices listed in this manual or on
the product, please call (800) 232-1195 M-F 8-5CT before using the generator.
AtLDANGER: POISONOUS GAS. Generators give off carbon monoxide, a
poisonous gas that can kill you quickly. You CANNOT smell it, see it, or taste it.
• ONLY run generator outdoors and away from air intakes, open windows,
and garages.
• Never use inside homes, garages, or sheds, EVEN IF you run a fan or open
doors and windows.
If you start to feel sick, dizzy, or weak while using the generator, shut it off and get
to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide
poisoning.
Ak WARNING: The exhaust from this product contains chemicals known to the
State of California to cause cancer, birth defects, or other reproductive harm.
A WARNING: Battery gives off explosive hydrogen gas
• Keep battery away from spark, flame, or cigarette.
• Do not connect or disconnect battery while generator is running.
• Service or use battery only in well ventilated areas.
aX WARNING: This generator may emit highly flammable and explosive gasoline
vapors, which can cause severe burns or even death. A nearby open flame can lead
to explosion even if not directly in contact with gas.
• Do not operate near open flame.
• Do not smoke near generator.
• Always operate on a firm, level surface.
• Always turn generator off before refueling. Allow generator to cool for at
least 2 minutes before removing fuel cap. Loosen cap slowly to relieve
pressure in tank.
• Do not overfill gas tank. Gas may expand during operation. Do not fill to
the top of the tank.
• Always check for spilled gas before operating.
• Empty gasoline tank before storing or transporting the generator.
• Before transporting, turn fuel valve to off and disconnect spark plug.
Ak WARNING: This generator produces powerful voltage, which can result in
electrocution.
• ALWAYS ground the generator before using it (see the "Ground the
Generator" portion of the "PREPARING THE GENERATOR FOR USE"
section).
• Generator should only be plugged into electrical devices, either directly or
with an extension cord. NEVER connect to a building electrical system
without a qualified electrician. Such connections must comply with local
electrical laws and codes. Failure to comply can create a backfeed, which
may result in serious injury or death to utility workers.
• Use a ground fault circuit interrupter (GFCI) in highly conductive areas
such as metal decking or steel work. GFCIs are available in-line with some
extension cords.
• Do not use in rainy or wet conditions.
• Do not touch bare wires or receptacles (outlets).
• Do not allow children or non-qualified persons to operate.
aX WARNING: Never connect a generator directly to any existing electrical
building circuit. The generator can backfeed into power lines and electrocute
nearby electrical repair workers.
aX WARNING: Battery contains sulfuric acid. Battery acid is poisonous. Tilting
the generator with the battery installed can cause battery acid to spill.
• Wear protective clothing and eyewear when servicing battery.
• Keep out of reach of children.
• Do not tilt generator with battery installed.
• If battery acid gets on your skin, wash with water immediately.
• If battery acid gets in your eyes, flush with water for at least 15 minutes and
call a doctor immediately.
• If battery acid is swallowed, drink a large amount of water or milk. Then
drink milk of magnesia or vegetable oil. Call a doctor immediately
aX WARNING: This generator produces heat when running. Temperatures near
exhaust can exceed 150 ° F (65 ° C).
• Do not touch hot surfaces. Pay attention to warning labels on the generator
denoting hot parts of the machine.
• Allow generator to cool several minutes after use before touching engine or
areas which heat during use.
CAUTION: Misuse of this generator can damage it or shorten its life.
• Use generator only for its intended purposes.
• Operate only on dry, level surfaces.
• Allow generator to run for several minutes before connecting electrical devices.
• Shut off and disconnect any malfunctioning devices from generator.
• Do not exceed the Wattage capacity of the generator by plugging in more
electrical devices than the unit can handle.
• Do not turn on electrical devices until after they are connected to the generator.
• Turn off all connected electrical devices before stopping the generator.
