DANGER
Carbon Monoxide
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.

3500W Propane Generator
Carbon Monoxide
When this tool is running, ensure that the area is well ventilated. Never run the
engine in an enclosed area. Run the engine in an open area or with an exhaust
evacuation system in an enclosed area.
WARNING! THE EXHAUST CONTAINS POISONOUS CARBON MONOXIDE
GAS THAT CAN CAUSE LOSS OF CONSCIOUSNESS AND MAY LEAD TO
DEATH.
Fuel and Oil
This product requires oil and fuel. Attempting to start the engine without oil will ruin
the engine and void the warranty. Work in well ventilated area. Keep cigarettes,
flames or sparks away from the work area or where fuel is stored.
WARNING! PROPANE IS EXTREMELY FLAMMABLE AND IS EXPLOSIVE
UNDER CERTAIN CONDITIONS. KEEP OUT OF REACH OF CHILDREN.
• Propane fuel and fumes are flammable and potentially explosive. Use proper fuel storage and
handling procedures. Always have multiple ABC class fire extinguishers nearby.
• Keep the generator and surrounding area clean at all times.
• Fuel or oil spills must be cleaned up immediately. Dispose of fluids and cleaning materials as per
any local, state, or federal codes and regulations. Store oily rags in a covered metal container.
• Never store fuel or other flammable materials near the generator.
General Precautions
WARNING! FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN
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.

General Precautions (cont’d)
Fuel 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® IS NOT RESPONSIBLE
FOR ANY DIRECT OR INDIRECT DAMAGE CAUSED BY FAILURE TO USE AN
APPROVED LINE CONDITIONER.

3500W Propane Generator
General Precautions (cont’d)
Work Area
• Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust. Generators create sparks which may ignite the dust 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 properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug 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 the plug in any way. Double insulation 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 increased risk 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 electric shock.
• Do not abuse the power cord. Keep power cords away from heat, oil, sharp edges, or moving
parts. Replace damaged power cords immediately. 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 electric shock.

Owner’s Manual
General Precautions (cont’d)
Electrical Safety (cont’d)
• All connections and conduits from the generator to the load must only be installed by trained and
licensed electricians, and in compliance with all relevant local, state, and federal electrical
codes and standards, and other regulations where applicable.
• The generator must be earth-grounded for fixed installations in accordance with all relevant
electrical codes and standards before operation.
• Do not attempt to connect or disconnect load connections while standing in water, or on wet or
soggy ground.
• Do not touch electrically energized parts of the generator and interconnecting cables or
conductors with any part of the body, or with any non-insulated conductive object.
• Connect the generator only to a load or electrical system (120 volt) that is compatible with the
electrical characteristics and rated capacities of the generator.
• Before servicing equipment powered by the generator, disconnect the equipment from its power
input.
• Keep all electrical equipment clean and dry. Replace any wiring where the insulation is cracked,
cut abraded or otherwise degraded. Replace terminals that are worn, discolored, or corroded.
Keep terminals clean and tight.
• Insulate all connections and disconnected wires.
• Guard against electric shock. Prevent body contact with grounded surfaces such as pipes,
radiators, ranges, and refrigerator enclosures.
Personal Safety
• Stay alert. Watch what you are doing, and use common sense when operating a generator. Do
not use generator while tired or under the influence of drugs, alcohol, or medication. A moment
of inattention while operating generators may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in
moving parts.
