SEVERE INJURY OR DEATH.
CAUTION: FAILURE TO FOLLOW THESE INSTRUCTIONS CAN ALSO
RESULT IN DAMAGE TO THE TOOL AND/OR THE ITEM YOU ARE WORKING
ON.
DANGER
CARBON MONOXIDE
Using a generator indoors WILL KILL YOU IN MINUTES.
Generator exhaust contains high levels of carbon monoxide (CO), a poisonous 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, 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.
· ONLY use a generator outdoors and far away from open windows, doors, and vents. These
openings can pull in generator exhaust.
Even when 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 could have carbon monoxide poisoning.
• Keepthegenerator and surrounding area clean at alltimes.

General Precautions (cont’d)
Gasoline and Oil (cont’d)
• Do not smoke, or allow sparks, flames or other sources of ignition around the engine and fuel
tank. Fuel vapors are explosive.
• Keep grounded conductive objects, such as tools, away from exposed, live electrical parts and
connections to avoid sparking or arcing. These events could ignite fumes or vapors.
• Do not refill the fuel tank while the engine is running or while the engine is still hot. Do not
operate the generator with known leaks in the fuel system
• Excessive buildup of unburned fuel gases in the exhaust system can create a potentially
explosive condition. This buildup can occur after repeated failed start attempts, valve testing, or
hot engine shutdown. If this occurs, open exhaust system drain plugs, if equipped, and allow the
gases to dissipate before attempting to restart the generator.
• Use only engine manufacturer recommended fuel and oil.
Hot Components
WARNING! ENGINE AND EXHAUST SYSTEM PARTS BECOME VERY
HOT AND REMAIN HOT FOR SOME TIME AFTER THE ENGINE IS RUN. WEAR
INSULATED GLOVES OR WAIT UNTIL THE ENGINE AND EXHAUST SYSTEM
HAVE COOLED BEFORE HANDLING THESE PARTS.
Power Output
This generator is not designed to power sensitive electronic equipment (including computers
and medical devices) without the addition of an approved line conditioner, which is sold separately.
CAUTION: ATTEMPTING TO POWER SENSITIVE ELECTRONIC EQUIPMENT
WITHOUT THE USE OF AN APPROVED LINE CONDITIONER MAY CAUSE
DAMAGE TO THE EQUIPMENT. GENTRON/UPC IS NOT RESPONSIBLE
FOR ANY DIRECT OR INDIRECT DAMAGE CAUSED BY FAILURE TO USE AN
APPROVED LINE CONDITIONER.

General Precautions (cont’d)
Work Area
• Keep your work area clean and welllit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases,ordust.Generators create sparkswhich may ignite thedust or fumes.
• Keep bystanders, children, and visitors away while operating a generator. Provide barriers or
shields as needed.
Electrical Safety
• Grounded tools must be plugged into an outlet properlyinstalledand
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify theplug in any way. Do not use any adapter
plugs.
• Grounding provides a low-resistance path to carry electricity away from the
user in the event of an electrical malfunction.
• Double insulated tools are equipped with a polarized plug where one blade is wider than the
other. This plug fits in a polarized outlet only one way. If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet.
Do not change theplug in any way. Doubleinsulation eliminates the need for the three-wire
grounded power cord and grounded power supply system.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators.
There is an increasedrisk of electric shock if your body is grounded.
• Do not expose generator to rain or wet conditions. Water entering a generator will increase the
risk of electricshock.
• Do not abuse the power cord. Keep power cords away from heat, oil, sharp edges, or moving
parts. Replace damaged power cordsimmediately. Damaged power cords increase the risk of
electric shock.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”.
These extension cords are rated for outdoor use, and reduce the risk of electricshock.
