Predator 8750 Generator Inverter Details

The Predator 8750 Generator Inverter boasts several advanced features for user safety and operational convenience. A critical safety component is the Carbon Monoxide (CO) Shutoff sensor, which provides an additional layer of protection. A flashing red light indicates dangerous CO levels, triggering an automatic generator shutdown and requiring immediate evacuation and ventilation of the area. A flashing yellow light signals a sensor malfunction, necessitating service before further use.

This generator includes both manual recoil start and a convenient electric start feature, powered by a pre-installed 12V, 1.6Ah Lithium Iron Phosphate (LiFEPO4) battery. For easy mobility, a wheel kit with sturdy wheels and feet is included and requires assembly. The integrated handle can be locked in either a raised or lowered position, enhancing portability and storage. Users must remove shipping brackets from the engine and frame before adding oil or gasoline to prevent warranty voiding.

The control panel features a digital display that cycles through various operational metrics, including voltage (U + reading), frequency (F + reading), current session runtime, and total accumulated runtime. This display also provides blinking maintenance reminders (P050, P100, P150, etc.) every 50 hours, which can be cleared by pressing and holding the Mode Button. This proactive alert system helps ensure timely upkeep and prolongs the generator's lifespan.

For electrical protection, the generator is equipped with Ground Fault Circuit Interrupter (GFCI) receptacles, which must be tested before each use to confirm functionality. Circuit breakers also safeguard the generator from overloading, automatically cutting electricity output if tripped. In case of an overload, users must unplug all loads, reset the breaker, and re-attach devices gradually, ensuring even distribution across outlets for optimal performance.

High-altitude operation above 3000 feet requires specific carburetor adjustments, typically involving the replacement of the main jet with an appropriate altitude kit. This adjustment, ideally performed by a qualified mechanic, prevents engine damage and ensures efficient operation. The generator mandates the use of 87+ octane unleaded gasoline treated with a fuel stabilizer, strictly advising against fuels containing more than 10% ethanol (E10) to maintain engine health and warranty validity.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Predator 8750 Generator Inverter, and we answer them below.


Can I use the Predator 8750 Generator Inverter indoors?
No, never use the generator indoors, including garages or sheds. Generator exhaust contains carbon monoxide, a poisonous gas you cannot see or smell. Always use it OUTSIDE and far away from windows, doors, and vents.

What does a flashing red light on the Carbon Monoxide sensor indicate?
A flashing red light signifies that dangerous levels of carbon monoxide gas have accumulated, and the generator will shut off. You must leave the area immediately until it has aired out and move the generator to a well-ventilated outdoor area before resuming operation.

What type of fuel is recommended for this generator?
Use 87+ octane unleaded gasoline that has been treated with a fuel stabilizer additive. Do not use gasoline containing more than 10% ethanol (E10) or E85 ethanol, as this can damage the engine.

How often should I change the engine oil?
Change the engine oil after the initial 25-hour break-in period. Subsequently, under normal operating conditions, change the oil monthly or every 20 hours of use.

What should I do if a circuit breaker trips on the generator?
If a circuit breaker trips, unplug all loads from the generator. Turn the tripped circuit breaker to the ON position and gradually re-attach loads. Ensure you do not exceed the generator's maximum power rating.

How do I properly ground the Predator 8750 Generator Inverter?
The generator must be earth-grounded before operation. Connect a #6 AWG grounding wire (not included) from the Grounding Terminal on the Control Panel to an earth-driven copper or brass grounding rod (not included), driven at least 24 inches deep into the earth.

What information is displayed on the digital panel?
The digital display cycles through voltage (U + reading), frequency (F + reading), current session runtime, and total accumulated runtime. It also shows blinking maintenance reminders (e.g., P050) every 50 hours.

What is the break-in period for the engine and why is it important?
The break-in period is approximately 25 hours of use. During this time, do not exceed 75% of the generator's rated capacity. Breaking in the engine ensures proper equipment and engine operation and requires an oil change afterward.

How do I prepare the generator for storage if it won't be used for a long time?
For storage longer than 20 days, clean the engine, treat the fuel with a stabilizer or drain the fuel tank and carburetor, change the engine oil, and pour one tablespoon of engine oil into the cylinder through the spark plug hole. Store it in a dry, level, well-ventilated area away from ignition sources.

Can I use the electric start feature immediately after purchase?
The electric start requires the installation of the included 12V, 1.6Ah Lithium Iron Phosphate (LiFEPO4) battery. Ensure the battery is properly connected to the engine before attempting to use the electric start feature.

How do I handle high altitude operation for my generator?
At altitudes above 3000 ft, the carburetor may need adjustment by a qualified mechanic through an altitude kit installation to maintain efficient fuel-air ratio and prevent engine damage. Operating without the proper kit can increase emissions and decrease performance.

What should I connect first to the generator to avoid damage?
Always connect the items that require the most wattage first. Then connect "inductive" loads, followed by any lights, and finally, voltage-sensitive appliances (such as TVs) plugged into a UL® Listed voltage surge protector.
