Chicago Generator 800 Watts Complete Review for Best Usage

The Chicago Generator 800 Watts is a great choice for those who need a reliable generator. It has many benefits that make it a great option for those who are looking for a generator. 

  1. It is very easy to use. You just have to pull the recoil starter and start using it.
  2. It is very affordable. This means that you can save money by buying this generator instead of another more expensive one. 
  3. The Chicago Generator 800 Watts is made with quality materials. This means that it will last longer and be more reliable than other generators. The most problematic part of this machine is the recoil kick it often gets worse.

I often use this portable generator for outdoor needs or camping, but along with its benefits, there is some issue also just as it produces too much noise that I can’t hear my friend talking to me.

The main problem is the starting of this generator, the most problematic process I have ever faced. Because I can hardly start it in less than 3 kicks.

Chicago 66619 Use Guide

The first thing you’ll want to do is understand your power requirement. You can use the generator to power your small home or office.

Once you’ve decided on your power needs, it’s time to start assembling the machine. Once it’s assembled, all you have to do is turn it on and start generating electricity!

To avoid severe harm from unintentional starting: Before beginning any inspection, repair, or cleaning procedures, switch the engine’s switch to the “OFF” position, wait for the engine to cool, and then disconnect the spark plug wire.

Always use gasoline and unleaded 2-cycle oil, don’t run the generator without a mixture. Running the engine with the wrong mixture or without mixing will result in irreparable engine damage. In my experience never filling the fuel tank to the top always allow some space for vibration overflow.  

After each start-up, let the engine run without any load for about three minutes to warm up and stabilize, and then plug the AC electric cord of 120 V appliances in the generator. 

Always check the fuel level and don’t allow the generator to completely out of fuel during the running of appliances.

Never put more than 800 watts of load on the generator, and if the AC circuit break turns it off, before operating again reduce the load, and reset the generator with the reset button.

Before shutting off the generator unplug the power cord to remove all electric load, and allow the generator to run for three minutes without load.
