Riverwalkers Gear Review - The Predator 4000 Generator from Harbor Freight Tools

If the grid goes down for more than a few hours, you could wind up suffering a bigger loss than your lights or TV. That fridge or freezer full of food items can be a total loss if you don’t have a means of auxiliary power to protect your food investment. If the power stays off for an extended period of time, you will probably need a portable generator to prevent a catastrophic loss.

The Predator 4000 generator from Harbor Freight Tools has received a lot of very positive reviews from numerous individuals. This made the Harbor Freight 4000 peak/3200 running watts-6.5 hp (212cc) gas generator #69676 an excellent choice for a survival gear review. 

Here is a list of the Predator 4000 generator main features:

212cc 6.5 HP air-cooled OHV gas engine

10 hours run-time @ 50% capacity

Low oil indicator and low oil shutdown

Heavy duty 1" steel roll cage

UL listed circuit breakers

Recoil start

Four 120 volt, 20 amp grounded receptacles

One 240 volt, 30 amp grounded receptacle

One 12 volt DC cigarette lighter port

First Impressions

1.) The generator unit I received arrived in a very timely fashion in only 7 days. The shipping time was estimated at 7 to 10 days. This was within the time frame specified.

2.) Straight out of the box I was very impressed by the fit and finish of the Predator 4000 Generator. A check for sharp edges, loose bolts or missing parts turned up negative. The paint job was excellent and exhibited no major flaws or defects.

3,) It also came with a small tool kit (Philips head screwdriver, spark plug wrench and an open end wrench), an Instruction Manual and a Quick Start Guide.

Straight out of the box this unit gets a solid 5 star rating.

Operational and Maintenance Features

One of the most important things about a piece of equipment is its ease of operation and the ability to perform routine maintenance in an easy and simple manner. The Predator 4000 Generator comes out very “user friendly” in this regard with only one exception.

1.) The Fuel Tank - The top-mounted fuel tank with a capacity of four gallons makes refueling an easy task. It includes a tank vent, top-mounted fuel gauge, a debris strainer and a large fuel cap with a retention chain. The large opening on the fuel tank made fueling the generator a very quick and simple process. 

2.) The Control Panel - The On/Off switch, the outlet receptacles, circuit breakers and low oil warning light are all located in a panel on the front side of the unit. This keeps everything together and makes it easy to access and check.

3.) The Spark Plug, Air Filter and Carburetor - The spark plug is easy to access and can be cleaned or changed easily with the spark plug wrench supplied in the tool kit that came with the unit. The air filter on this generator (foam) was easy to access without additional tools, very simple to clean (soap and water) and then re-install. The carburetor also included a drain plug to assist with long term storage. This makes the maintenance of these items a simple task without any extra hassle. 

4.) Oil Fill and Drain - This is the exception when it comes to operation and maintenance of this generator. Access to the oil fill plug is somewhat of a hassle. You will need a funnel with a long “flexible” spout or an oil squirt can (my choice) to add oil to the unit. Draining the oil also requires the unit to be tilted. This is something that could be easily corrected with the addition of an oil drain plug to the engine.

Overall, I would rate the operation and maintenance of this generator 4 out of 5 stars. While the majority of operation and maintenance is a simple task, the process of filling and changing the oil is simply not as “user friendly” as it could be for what will most likely be a fairly frequent task.

The Load Test

After filling the generator with the required amount of oil (approximately 3/4 quart or .6 liter) and adding approximately 2 1/2 gallons (half a tank by the fuel gauge) of treated fuel with a stabilizer additive, it was time to pull the handle and crank this new generator up. 

1.) Light Load - The unit cranked on the third pull and the engine smoothed out very quickly in less than a minute. It was allowed to operate about 15 minutes without a load. It was then shut down and re-started. It cranked on the first pull and was allowed to run about 5 minutes before a light load was applied.

A small lamp was hooked up to the init and worked well with no noticeable increase in the load on the generator. All power outlets on the unit were then checked and found to be functioning properly. The generator was run with this light load for approximately 45 minutes.

An LP14-30 cord was then connected and a light load used to check the four prong outlet on the generator. This was also found to be operating correctly.

2.) Heavy Load - A heavy load was not placed on the unit because the unit requires a break-in time of about 3 hours and was only operated about 2 hours during this initial use. 

Here is an update with the results of a heavy load test and the installation of a wheel kit:

Final Impressions

1.) The Predator 4000 Generator is a very “user friendly” piece of equipment and all features worked properly.

2.) Its cost is relatively inexpensive and can be found on sale frequently which makes it an even better buy. The fit and finish of this generator was also excellent straight out of the box.

3.) Most of the operation and maintenance chores on this generator are easy to accomplish. The only exception is the oil fill and drain issues noted previously.

4.) The generator unit is heavy (128 pounds). Unless you are planning a more permanent installation, you will probably need to order the wheel kit that is available for this generator. This will make moving it to various locations an easier task.

5.) You also need to add a torpedo level to the tool kit. This will allow you to check the level of the unit. Units that are not level can cause problems with the low oil shutdown feature or affect how efficiently fuel feeds from the gas tank.

6.) Make sure to read the Owner's Manual and Instructions prior to operating this unit.

The Predator 4000 Generator makes an excellent and very affordable addition to your preparedness gear.
