Jump to the sectionProduct Overview
The Husqvarna 1055GN is a 5500-watt portable generator designed to provide reliable electrical power for compatible lighting, appliances, tools, and motor loads. It features a single-cylinder engine and a revolving field AC generator. This unit is intended for outdoor use only and requires final assembly before initial operation.
Safety Information
Danger: Using a generator indoors can kill you in minutes. Generator exhaust contains carbon monoxide, a colorless, odorless, poisonous gas. Always operate the generator outdoors, far away from windows, doors, and vents. Never run the engine in an enclosed area, including garages or RV compartments.
Warning: The generator produces hazardous voltage. Failure to isolate the generator from the power utility can result in death or injury to utility workers due to backfeed. Always use approved transfer equipment for backup power applications. Additionally, fuel and its vapors are extremely flammable; never refuel while the engine is hot or running.
Assembly and Setup
The generator requires the installation of the wheel kit and support legs before use. Ensure the unit is placed on a level surface. Before starting, add the provided engine oil and fill the tank with fresh, unleaded gasoline. Do not overfill the fuel tank to allow for expansion.
Operation
To start the engine, ensure the fuel valve is in the ON position, set the choke to CHOKE, and turn the rocker switch to ON. Pull the recoil starter handle slowly until resistance is felt, then pull rapidly. Once started, gradually move the choke lever to the RUN position. To stop the engine, turn off and unplug all electrical loads, let the engine stabilize at no-load, turn the rocker switch to OFF, and move the fuel valve to the OFF position.
Maintenance
Regular maintenance is essential for performance and longevity. Change the engine oil after the first 5 hours and every 50 hours thereafter. Service the air cleaner every 25 hours, and inspect the spark plug and spark arrester every 100 hours. Always keep the generator clean and free of debris, especially around cooling air slots.
Troubleshooting
If the generator fails to produce power, check the circuit breakers. If the engine runs poorly or fails to start, verify the fuel level, check the air cleaner, and ensure the spark plug wire is connected. For persistent issues, contact an authorized service dealer.

Common problems
Engine is running, but no AC output is available.
Reset the circuit breaker or check for a faulty connected device.
Engine runs well at no-load but bogs down when loads are connected.
Check for a short circuit in the load or ensure the generator is not overloaded.
Engine will not start or runs rough.
Check if the rocker switch is ON, fuel valve is open, air cleaner is clean, or if the spark plug needs replacement.
Engine shuts down during operation.
Check fuel level and ensure the unit is on a level surface to prevent low-oil protection shutdown.
Engine lacks power.
Reduce the electrical load or replace a dirty air filter.
