ManualMore Details

Brands like Predator can’t risk their reputation. So, they include a lot of safety features such as –

  • Low oil indicator
  • Circuit breakers
  • Low fuel shutoff
  • There is a fuel cutoff so that you can bleed the carburetor dry. It helps to prevent clogging.

Along with the generator, you will have the following tools and accessories in the package –

  • Screwdriver
  • Spark plug wrench
  • Extended oil funnel
  • Wheel kit
  • The wheel is very smooth and made with high-quality rubber. This rubber also grants you better friction with any hard surface.

Features of Predator 4000 Watt Generator


There is a 212cc engine producing 6.5 horsepower. This is an air-cooled OHV engine. So you won’t have to buy any additional coolant for the machine. The OHV type engine gives you a higher low-end torque in a small space.

On a 50% load, it will provide you with a runtime of 10 hours. Although you will only have a recoil start, it is very smooth and will start in just one pull.

The air filter has a very secure location and is equipped with a thick foam cover. Although the oil tank has a gauge, its positioning is terrible. Manufacturers recommend 10W-30 engine oil unless you are in the extreme cold where you have to use a 5W-30.

Outlet Configuration

All of the GFCI outlets on the generator are UL listed. They also come with their respective circuit breakers. Here are all the AC outlets you will have in the configuration –

  • Four 120-volt three-prong duplex outlets rated at 20 amps
  • A 240-volt four-prong outlet rated at 30 amps

The maximum output from the AC outlets will be 26 amps in total. And, each of those outlets will give you a maximum of 13 amps. So, if you want to draw the maximum power, you will have to use at least two outlets. However, you can’t use both stories of the duplex configuration at once.

A separate section for the DC outlet also houses its breaker. It is a 12-volt outlet rated at 8.3 amps, which is pretty decent for a generator pushing 12-volts out.


It primarily runs on gasoline. Although a 10% ethanol blend will not be a problem, don’t use E85 in this. You will need 87+ octane unleaded gasoline for the machine.

Moreover, you don’t have the burden of mixing different oils for the generator. However, manufacturers recommend checking the oil every eight hours. There is a gauge on the top of the tank to check the fuel.

The fuel tank is threaded with a chain. Under the cap, you will see a filter that separates debris from the fuel.

Power Generation

As it is written in the name, it has a 4000 surge wattage. But you will have a running or continuous wattage of 3200. And remember that there is no eco-mode. So, it is always on and always running.

It has a wattage estimate chart which we find very useful because you can’t exceed more than 26 amps in total. You need to be careful about that.


Unexpectedly, this is not very noisy. We were hoping a much louder noise when we first saw it to fire up. But it was even below 65 decibels from 20 feet, along with all the traffic near the generator.


It has a full metal body with a steel roll cage. The stand and wheels also have a firm grip on the ground. So, it is not going to shake much, increasing the longevity of the product.


All those heavy built materials drive the weight high. When dry, it is about 100 pounds. With fuel, it is going to be around 128 pounds. But as we have said before, you will have a wheel kit to move it around.

The Features You Shouldn’t Expect

Here are some features that you shouldn’t be expecting from a generator of its price. So if you are searching the best generators available in the market then have a visit to top rated 4000 watt generator.

No Eco-Mode

You won’t be able to change the RPM. It gives you constant power.

Dual Fuel

It only uses gasoline. So, you can’t switch to any other fuel.

Limitations in Maximum Power Output of Outlets

The AC outlets push out a maximum power of 13 amps each while the total power output capability of the generator is 26 amps. So, you can use only two outlets at maximum power simultaneously. Use all the receptacles at ones as long as you don’t go over 26 amps.

Note that even a high power air conditioner can require 16-18 amps. So, you may wanna use the power chart before getting the generator connected.

Inconvenient Placing of Oil Filling Position

Although I like the fact that oil will not drip on any part of the generator. It is located in a place that will make refilling way harder.
