GENERATOR SAFETY WARNINGS
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.
NEVER use a generator inside homes, garages, crawl spaces, or other partially 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. ONLY 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: RISK OF EXPLOSION. HIGH FLAMMABLE: This generator may emit highly flam-
mable 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.
• 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 fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow
for expansion.
• Always check for spilled fuel before operating.
• Empty fuel tank before storing or transporting the generator.
• Before transporting, turn fuel valve to OFF and disconnect spark plug wire.
WARNING: If this generator is used as a supply for a BUILDING’S WIRING SYSTEM, the generator
MUST be installed by a qualified electrician and connected to a transfer switch as a separately derived
system in accordance with all applicable laws and electrical codes and the National Electrical Code,
NFPA 70. The generator shall be connected to a transfer switch that switches all conductors excluding the equipment grounding conductor. The frame of the generator shall be connected to an approved
grounding electrode.
California Proposition 65 WARNING: This product contains chemicals and produces exhaust
known to the State of California to cause cancer, birth defects and other reproductive harm.

GENERATOR SAFETY WARNINGS
WARNING: Do not let comfort or familiarity with the product replace strict adherence to product
safety rules. Failure to follow the safety instructions may result in serious personal injury.
OPERATING ENVIRONMENT SAFETY
1. Using a generator indoors can kill you in minutes. Only use a generator outside and far away from windows, doors and vents.
2. Do not operate near open flame or flammable materials. 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 it isn’t directly in contact with gasoline.
3. Do not smoke near the generator.
4. Do not use the generator in rainy or wet conditions; doing so significantly increases the risk of electrical
shock.
5. Always operate the generator on a dry, firm, level surface.
6. Do not allow children or non-qualified persons to operate the generator.
GENERATOR PREPARATION SAFETY
1. Always ground the generator before using it to maximize safety (see the “GROUNDING THE GENERATOR”
portion of the “GENERATOR PREPARATION” section on page 11).
2. Do not overfill fuel tank, as gasoline may expand during operation. Do not fill to the very top of the tank.
Leave room for gasoline expansion. Always check for spilled fuel before operating.
3. If any part of the generator or electrical device is broken, damaged, or defective, make sure it is repaired
or replaced before operation. Service should only be performed by a qualified technician. Do not use receptacles or cords that show signs of damage, such as broken or cracked insulation.
4. Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or steel
work. Extension cords with in-line GFCIs are recommended for these operations to maximize safety.
5. NEVER connect the generator to a building’s 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.
NOTE: For 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 of the components, possibly leading to a generator failure.

GENERATOR SAFETY WARNINGS
GENERATOR OPERATION SAFETY
1. Only use the generator for its intended purposes. Modifying or using the generator for operations for
which it was not designed may cause hazards and personal injury.
2. Do not touch bare wires or receptacles (outlets).
3. Do not exceed the wattage capacity of the generator by plugging in more electrical devices than the unit
can handle.
4. Allow generator to run for several minutes before connecting electrical devices.
5. Do not turn ON electrical devices until after they are connected to the generator.
6. Generators vibrate in normal use. During and after the use of the generator, inspect both the generator as
well as extension and power supply cords for damage resulting from vibration.
7. Do not touch HOT PARTS. This generator produces heat when running. Temperatures near exhaust can
exceed 150º F (65º C). Allow generator to cool down after use before touching engine or areas of the generator that become hot during use.
8. Turn off all connected electrical devices before stopping the generator.
9. 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.
10. Turn the engine switch to “OFF” position when the engine is not running.
11. Empty fuel tank before storing or transporting the generator. Do not store generator or gasoline near
furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions. Store the
generator and fuel away from sparks, open flames, pilot lights, heat and other sources of ignition.
TO MAXIMIZE THE LIFESPAN OF YOUR GENERATOR:
We recommend running your generator at least once a month for 15 to 30 minutes. Start the generator
according to the instructions and plug a small load in to make sure the outlet is producing electricity.
If you do not run it often, it will greatly shorten the lifespan and performance of the generator.
CAUTION: Misuse of this generator can damage it or shorten its lifespan.

HIGH ALTITUDE OPERATION ABOVE 3000 FEET
The fuel system on this generator may be affected by operation at high altitudes. Proper operation can be
ensured by installing an altitude kit. The kit can be ordered from wenproducts.com by searching the part
number 56105-HA. Use jet nozzle #68 for altitudes between 3000 to 6000 feet; use jet nozzle #65 for altitudes between 6000 to 8000 feet. At elevations above 8000 feet, the engine may experience a decrease in
performance, even with the proper altitude kit.
Operating this generator without said kit may increase the engine’s emissions and decrease both fuel
economy and performance. The kit should be installed by a qualified mechanic. Refer to the instructions
included with your altitude kit for more information about installation.
CAUTION: Be sure to UNINSTALL the high altitude kit when operating at altitudes below 3000 feet. Engines
with the high-altitude kit installed operated at lower altitudes could cause severe engine damage and affect
emissions compliance.
WARNING: To prevent serious injury from fire, follow the kit installation procedures in a well-ven-
tilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it
to cool before proceeding. Do not smoke near the generator. Warranty will be void if adjustments are not
made for high altitude use.
