Operating Precautions

⚠️WARNING! TO PREVENT SERIOUS INJURY, DEATH, AND GENERATOR AND/OR EQUIPMENT DAMAGE FROM ELECTRIC SHOCK AND FIRE:

1. Never use generators indoors, including garages, basements, crawl spaces, and sheds. Opening doors/windows or using fans will NOT prevent carbon monoxide buildup.
2. Keep generators outdoors and far from open doors, windows, and vents to avoid toxic carbon monoxide levels indoors.
3. If you feel sick, dizzy, or weak while using generators, get to fresh air immediately. Carbon monoxide can quickly lead to incapacitation and death.
4. Keep children and pets away from the Parallel Kit, especially while it is operating.
5. Do not exceed the maximum power rating of the generators. Ensure the total electrical rating of connected tools/appliances does not exceed the generator's capacity. Check that startup surge is within the generator's limit.
6. Avoid substantial overloading, which trips the circuit breaker. Slight overloading may not trip the breaker but can lead to premature generator failure.
7. Do not attempt to connect or disconnect load connections while standing in water or on wet/soggy ground.
8. Do not touch electrically energized parts of generators, interconnecting cables, or conductors with any part of the body or any non-insulated conductive object.
9. Insulate all connections and disconnected wires.
10. Guard against electric shock. Prevent body contact with grounded surfaces like pipes, radiators, ranges, and refrigerators.
11. Only connect two identical Inverter Generators together using the Parallel Kit.
12. Connect the Parallel Kit only to terminals marked "Parallel Outlets" on the generator's front panel.
13. Do not remove or connect the Parallel Kit while generators are running.
14. Do not attach a Parallel Kit to only one generator.
15. Do not attach any load to any other outlet on a generator that has a Parallel Kit attached.
16. Wear safety goggles during use.
17. People with pacemakers should consult their physician before use. Electromagnetic fields near a pacemaker could cause interference or failure. Caution is necessary near the engine's magneto or recoil starter.
18. Accessories suitable for one piece of equipment may be hazardous when used on another.
19. Stay alert, watch what you are doing, and use common sense. Do not use while tired or under the influence of drugs, alcohol, or medication.
20. Dress properly. Do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts. Loose items can be caught in moving parts.
21. Use equipment and accessories in accordance with these instructions and for their intended purpose, considering working conditions. Using equipment for unintended operations could result in a hazardous situation.
22. WARNING: This product contains or, when used, produces a chemical known to the State of California to cause cancer and birth defects or other reproductive harm (California Health & Safety Code § 25249.5, et seq.).
23. Before use, check for misalignment or binding of moving parts, breakage of parts, or any other condition affecting operation. If damaged, have the equipment serviced before use. Many accidents are caused by poorly maintained equipment.
24. Use the correct equipment for the application. Do not modify the equipment or use it for a purpose for which it is not intended.

Service Precautions

1. Before service, maintenance, or cleaning, unplug the Parallel Kit from both generators.
2. Keep all electrical equipment clean and dry. Replace any wiring with cracked, cut, or degraded insulation. Replace worn, discolored, or corroded terminals. Keep terminals clean and tight.
3. Do not alter or adjust any sealed part of the equipment or its engine. Only a qualified service technician may adjust parts affecting governed engine speed.
4. Wear safety goggles during service.
5. Maintain labels and nameplates on the equipment, as they carry important information.
6. Have equipment serviced by a qualified repair person using only identical replacement parts to ensure safety. Do not attempt service procedures not explained in this manual or if uncertain about your ability to perform them safely.
7. Store equipment out of the reach of children.
