Introduction
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.
Setup
Before initial use, ensure the generator is properly prepared for operation. This involves adding engine oil and fuel.
1. Add Engine Oil
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. Add Fuel
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.

- Turn the fuel cap vent lever to the 'ON' position.
- Turn the multi-switch to the 'CHOKE' position.
- Pull the recoil starter handle firmly until the engine starts.
- Once the engine starts, slowly move the multi-switch to the 'RUN' position.
2. Power Panel Overview
- Indicator Lights: Includes output, overload, low oil, and CO warning lights.
- Eco Mode Switch: Activates Economy Mode for improved fuel efficiency.
- AC Outlets: Two 120V/20A outlets and one 120V/30A outlet.
- USB Ports: DC 5V 1A/2.1A for charging mobile devices.
- Parallel Connection: Allows two compatible generators to be connected for increased power output.
- AC Breaker: Protects against overload.
- Reset Button: Used to reset the generator after an overload or CO Detect shutdown.
3. Eco-Mode Feature
The Eco Mode switch, when activated, adjusts the engine speed to match the load, reducing fuel consumption and noise levels. For optimal efficiency, engage Eco Mode when running light loads.

Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator. Always refer to the full owner's manual for a complete maintenance schedule.
1. Engine Oil Change
It is recommended to change the engine oil after the first 20 hours of use, or the first month, whichever comes first. Subsequent oil changes should follow the schedule in your manual.
2. Spark Plug Inspection
Regularly inspect the spark plug for wear and proper gap. Replace with the specified spark plug type as needed. Access to the spark plug is typically via a removable panel.
3. Air Filter Cleaning
Check and clean the air filter periodically. A dirty air filter can reduce engine performance and fuel efficiency.
4. Spark Arrester Maintenance
The generator is US Forestry approved and includes a spark arrester. Ensure the spark arrester is clean and free of carbon buildup to maintain proper operation and prevent fire hazards.
Troubleshooting
If your generator experiences issues, consult the following common troubleshooting tips. For complex problems, contact customer support.
- Generator Not Starting: Check fuel level, oil level, spark plug, and ensure the multi-switch is in the correct starting position.
- No Power Output: Check if the AC breaker has tripped. Press the reset button if necessary. Ensure the generator is not overloaded.
- CO Detect Shutdown: If the CO warning light illuminates and the generator shuts down, move the generator to an open, outdoor area with fresh air. Do not run the generator in enclosed spaces. Allow it to cool before attempting to restart.
- Low Oil Alarm: If the low oil indicator light is on, check and add engine oil to the recommended level.
- Overload Alarm: If the overload indicator light is on, disconnect some appliances to reduce the load, then press the reset button.
