ManualMore Details

Making a mistake with generators can cost you a lot. That’s why manufacturers included the following features to make it safer –

  • Low oil alert
  • Oil sensor
  • Automatic low oil shutdown system
  • UL listed breakers
  • These features make sure that the generator retains its value over the years. There is also a well-crafted user manual that shows you how to start and operate the machine. You will also have a chart that shows you the power requirements for your electronics. Follow that to prevent any voltage imbalance.

Here are the tools and accessories that come with the generator –

  • Spark plug wrench
  • Funnel
  • Regular wrench
  • Screwdriver
  • Battery mount
  • All of these are high-quality tools. They should be accompanying the generator throughout its lifetime.


Engine and Power Output

There is a 420cc air-cooled OHV engine powering this machine. It is a 13 horsepower engine. With this machine, the generator can give you a surge wattage of 8750 and a continuous wattage of 7000.

Fuel and Oil

It primarily uses gasoline. To be specific, it uses 87+ unleaded octane. There is a 6-gallon tank that will keep the generator running for 12 hours at 50% load. For temperatures over zero degree Celsius you can use 10W-30 type oil, and for freezing temperatures, you need to use 5W-30.

The cap firmly locks in place. There is a filter under the cap which catches large debris. However, the generator lacks a filter for small sediments that form in old gasoline.

Outlet Configuration

To distribute the power, the generator has the following receptacles –

  • Four duplex 120 volt AC outlets rated at 20 amps
  • A 120 volt three-prong AC twist-lock outlet rated at 20 amps
  • A 120/240 volt four-prong RV twist-lock outlet rated at 30 amps
  • A 12 volt DC outlet

All of these outlets are GFCI receptacles. Moreover, they each have a UL listed push button breaker. So, one push of this button will get the power back on if it ever gets overloaded.


It is an all-steel model. Manufacturers call it the steel roll cage design. This design gives you maximum protection from physical hits. The shock-absorbing engine mounts also help to decrease the stress on the structure. There is also a high-quality air filter that is insulated with thick foam.

Benefits of 8750 Watt Generator

The features were great. But here we list some of the positives of the generator that is unique to its kind.


Although the unit is huge, it is relatively easy to move it around. It has a convenient mobility kit with a lockable handle. The handle is ergonomically designed to assist you in pulling the generator. There is also a foam cover on the handle, which prevents fatigue. However, the mobility kit has to be bought separately.

Electric Start

You will have a separate place for the battery that is needed to power the electric start mechanism. But the battery doesn’t come with the generator. If you get the battery, you will have the electric start feature enabled in the generator.

Adjustment of Valve Lash

As it has an OHV engine, you can open the overhead cam to adjust the valve lash. You won’t be able to do this with other types of engines.


Other generators producing this kind of power are incredibly loud. From 7 meters, this generator has a noise measurement of 76 decibels, which is great for 7000 continuous watts of energy.

Altitude Kit

Some generators can’t function properly above a certain altitude. If you are living in a high altitude region, this could be a big problem for you. But there is an altitude adjustment kit that comes with the generator, making the machine useful in a variety of heights.

Low Maintenance

Compared to other brands, Predator generators always need minimum maintenance. You just have to keep it clean. Make sure that your gasoline is fresh and don’t leave unused gas in the machine as it will clog up the system.

Shock Absorbers

Almost all users miss this feature that the engine is mounted on four legs, which are designed to absorb a lot of rattling from the engine. This increases the longevity of the machine and also reduces the noise.


Like all other Predator generators, this one is also certified by the EPA and CARB. Yes, you can get it in California and all the other states.

Drawbacks of This Generator

Here are some of the drawbacks of the product. However, they have their remedies.


It weighs over 230 pounds. Even unpacking it is a hard nut to crack. You might need a hand truck and a trolley to move it around before setting up the mobility kit.

No Room for Fuel Filter in the Fuel Line

Although there are a fuel sediment bowl and a filter under the fuel tank cap, you will not have any fuel filter for smaller sediments. You can’t even install your own filter because the fuel line is very small. So, make sure that your fuel is always fresh.
