GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the
product, please call [phone] M-F 8-5 CST before using the generator.
DANGER: CARBON MONOXIDE. Using a generator indoors CAN KILL
YOU IN MINUTES.
Generator exhaust contains carbon monoxide (CO). This is a poison gas 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.
xNEVER 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.
xONLY use a generator outside and far away from windows, doors, and vents. These
openings can pull in generator exhaust.
Even if 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 may have carbon monoxide poisoning.
WARNING: The exhaust from this product contains chemicals known to the
State of California to cause cancer, birth defects, or other reproductive harm.
WARNING: This generator may emit highly
flammable and explosive gasoline vapors, which can
cause severe burns or even death, if ignited. A nearby open flame can lead to
explosion even if not directly in contact with gasoline.
xDo not operate near open flame.
xDo not smoke near generator.
xAlways operate on a firm, level surface.
xAlways 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.
xDo not overfill fuel tank. Gasoline may expand during operation. Do not fill to the
top of the tank. Allow for expansion.
xAlways check for spilled fuel before operating.
xEmpty fuel tank before storing or transporting the generator.
xBefore transporting, turn fuel valve to off and disconnect spark plug cap.

WARNING: This generator produces powerful voltage, which can
result in electrocution.
xALWAYS ground the generator before using it (see the “Ground the Generator”
portion of the “GENERATOR PREPARATION” section).
xGenerator 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 back-feed, which may result in serious injury or death
to utility workers.
xUse 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.
xDo not use in rainy conditions.
xDo not touch bare wires or receptacles (outlets).
xDo not allow children or non-qualified persons to operate.
WARNING: This generator produces heat when running. Temperatures
near exhaust can exceed 150º F (65º C).
xDo not touch hot surfaces. Pay attention to warning labels on the generator identifying
hot parts of the machine.
xAllow generator to cool down after use before touching engine or areas of the generator
that become hot during use.
CAUTION: Misuse of this generator can damage it or shorten its life.
xUse generator only for its intended purposes.
xOperate only on dry, level surfaces.
xAllow generator to run for several minutes before connecting electrical devices.
xShut off and disconnect any malfunctioning devices from generator.
xDo not exceed the wattage capacity of the generator by plugging in more electrical devices
than the unit can handle.
xDo not turn on electrical devices until after they are connected to the generator.
xTurn off all connected electrical devices before stopping the generator.
xTurn engine switch to “off” position when the engine is not running.

IMPORTANT SAFETY INSTRUCTIONS
xSAVE THESE INSTRUCTIONS – This manual contains important instructions for WEN
Power 9000E generator that should be followed during installation and maintenance of the
generator.
xGenerators vibrate in normal use. During and after the use of the generator, inspect the
generator as well as extension and power supply cords connected to it for damage resulting
from vibration. Have damaged items repaired or replaced as necessary. Do not use plugs or
cords that show signs of damage such as broken or cracked insulation or damaged blades.
xFor power outages, permanently installed stationary generators are better suited for
providing backup power to the home. Even a properly connected portable generator can
become overloaded. This may result in overheating or stressing the generator components,
possibly leading to a generator failure.
xWARNING: When this generator is used to supply a building wiring system:
Generator must be installed by a qualified electrician and connected to a transfer switch as
a separately derived system in accordance with the National Electrical Code, NFPA 70.
The generator shall be connected to a transfer switch that switches all conductors other than
the equipment grounding conductor. The frame of the generator shall be connected to an
approved grounding electrode.
In addition to the previous safety notices, please become familiar with the safety and hazard
markings on the generator.
