2. Safety Information
Operating a generator safely is paramount. Always follow these guidelines to prevent serious injury or death.
Carbon Monoxide (CO) Safety
Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operating a generator indoors or in partially enclosed spaces can lead to fatal carbon monoxide poisoning.
- ALWAYS operate the generator outdoors in an open area, away from windows, doors, and vents.
- Ensure exhaust fumes are directed away from occupied buildings.
- Install battery-operated carbon monoxide alarms in your home or any enclosed space where the generator's exhaust could potentially enter.

Your FIRMAN T12071 generator is equipped with CO Alert technology. This system automatically shuts down the engine if unsafe levels of carbon monoxide are detected around the generator or if a CO Alert system fault occurs. Refer to the CO Indicator Light section for more details.

General Safety Precautions
- Keep children and pets away from the generator.
- Do not operate the generator in wet conditions or expose it to rain.
- Ensure proper grounding of the generator.
- Never refuel a hot or running engine. Allow the generator to cool down before adding fuel.
- Store fuel in approved containers in a well-ventilated area, away from ignition sources.
- Use appropriate extension cords rated for outdoor use and the generator's power output.

4. Operating Instructions
Follow these steps for safe and efficient operation of your FIRMAN T12071 generator.
Pre-Start Checks
- Ensure the generator is on a level surface outdoors, away from any structures.
- Check engine oil level.
- Verify sufficient fuel (gasoline, propane, or natural gas).
- Ensure all electrical loads are disconnected from the generator outlets.
Starting the Generator (Electric Start)
- Select the desired fuel source using the fuel selector switch.
- Turn the fuel valve to the 'ON' position.
- If starting on gasoline, ensure the choke is set appropriately for cold or warm starts.
- Press and hold the electric start button until the engine starts.
- Once started, slowly return the choke to the 'RUN' position (if used).

Shutting Down the Generator
- Disconnect all electrical loads from the generator outlets.
- Allow the generator to run for a few minutes without load to cool down.
- Turn the fuel valve to the 'OFF' position.
- Allow the engine to run until it runs out of fuel (if using gasoline) or until it stops (if using propane/natural gas). This helps prevent fuel-related issues during storage.
- Turn the engine switch to the 'OFF' position.
5. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your generator.
Maintenance Schedule
- Before Each Use: Check engine oil level, inspect air filter, check fuel level, inspect for loose fasteners or damage.
- First 20 Hours / First Month: Change engine oil.
- Every 50 Hours / Every 3 Months: Clean air filter, check spark plug, check valve clearance (professional service recommended).
- Every 100 Hours / Every 6 Months: Change engine oil, replace spark plug, inspect fuel filter.
- Every 300 Hours / Annually: Replace air filter, inspect fuel lines, clean combustion chamber (professional service recommended).
Storage
For extended storage, prepare your generator to prevent issues:
- Drain the fuel tank and carburetor (if using gasoline) or run until fuel is depleted.
- Change the engine oil.
- Remove the spark plug and pour a small amount of engine oil into the cylinder. Rotate the engine a few times to distribute the oil, then reinstall the spark plug.
- Clean the exterior of the generator.
- Store in a clean, dry, well-ventilated area.
