Frequently Asked Questions - QT07068GNAC Generac
What type of fuel does the Generac QT07068GNAC use?
The generator runs on either natural gas or liquid propane, providing flexible fueling options for your home backup power needs.
How do I start the generator manually?
While designed for automatic operation, you can start it manually by pressing the manual start button on the control panel after ensuring the fuel supply is turned on and the battery is charged.
How often should I change the oil?
Change the oil after the first 25 hours of operation, then every 100 hours or annually, whichever comes first. Use the recommended oil type specified in the manual.
Can I power my entire house with this generator?
This 7,000-watt generator can power essential appliances such as refrigerators, lights, and a sump pump, but not high-draw items like central air conditioning. A licensed electrician can help determine suitable loads.
How does the automatic transfer switch work?
The transfer switch monitors utility power. When it detects an outage, it signals the generator to start and transfers power to your home within seconds. When utility returns, it switches back and shuts down the generator.
What maintenance is required?
Regular maintenance includes oil changes, air filter cleaning, spark plug replacement, battery inspection, and keeping the enclosure clean and free of debris.
What safety features are included?
Safety features include low-oil shutdown to protect the engine, over-crank protection to prevent starting system damage, and ground fault protection to reduce electrical shock risk.
How do I clean the air filter?
Remove the air filter cover, take out the filter, wash it with warm water and mild detergent, let it dry completely, then re-oil it lightly before reinstalling. Replace it if it's torn or damaged.
What should I do if the generator fails to start?
Check the fuel supply, ensure the battery is charged, verify all safety switches are reset, and inspect the spark plug. If it still won't start, consult the troubleshooting section of the manual or contact a Generac service dealer.
Where should I install the generator?
Install it outdoors on a level, non-combustible surface, at least 5 feet from windows, doors, and vents. Ensure proper airflow and clearance for maintenance.
