Introdución
This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your GENMAX GM2200i portable inverter generator. Please read this manual thoroughly before operating the generator.
The GENMAX GM2200i is powered by a 79.7cc 4-stroke OHV gas engine, producing 2200 starting watts and 1800 running watts of clean power (less than 3% THD). Its inverter technology makes it safe for sensitive electronics. Weighing only 41.8 pounds, its lightweight and compact design with a sturdy handle ensures easy portability. The generator operates at a low noise level of 58 dBA and features an Economy Mode for maximum fuel efficiency, offering up to 6 hours of run time at 50% load on a 1-gallon gas tank. It includes a CO Detect shutdown sensor for carbon monoxide poisoning prevention.
Configuración
Before initial use, ensure the generator is properly prepared for operation. This involves adding engine oil and fuel.
1. Engade aceite de motor
The generator requires 5W-30 engine oil. Locate the oil fill cap on the side of the engine. Remove the cap and carefully pour the recommended amount of oil into the engine. Do not overfill. Refer to the owner's manual for exact oil capacity and detailed instructions.
2. Engadir combustible
Use unleaded gasoline with an octane rating of 87 or higher. The fuel tank capacity is 1 gallon. Open the fuel cap and carefully fill the tank. Ensure the fuel cap is securely tightened after filling. Do not use oil/gas mixture.
