Firman P03603 4550/3650 Packaging And First Impressions

As we heard ample positive reviews about this product, we decided to give it a try. We ordered it online and received it within the estimated date. The product has a warranty of 3 years.

When it arrived, it was well packed in a thick carton box that was tightly sealed. When we opened the box, we saw that the generator was surrounded by foam. This would avoid any damage during shipping. The generator looks exactly like the picture and will not disappoint you at all.

Everything that one needs to start the generator is already inside the carton box. It is lightweight, and we were able to lift it easily. It comes along with a funnel and a quart of oil during delivery. We had also been provided with an elaborate manual on setting up and using the generator. There was also a handy remote to operate the generator. To get started, all we needed to do was get gas.

It took us nearly one hour to get the generator running. We just had to install the wheel kit, the handle, and attach the batteries. We then added oil using the quart and put in some gas. Pressed the start button on the remote, and the generator was functioning in no time!

Properties Of The Firman P03603 4550/3650 Generator

We mostly keep generators outside our houses. The most helpful feature of this generator is that it can be automatically switched on and off from yards away.

So, if you need to switch it on in the night, you do not need to go all the way to do it. But if you are not comfortable with using the remote, you also have the option of operating it through the button or the drawstring.

The never-flat tires of the wheel kit and the high folding handle make it suitable for moving. This is the reason why these generators are perfect for camping, where there might be difficult terrain.

You can easily monitor your operating hours and volts through the digital display. A low oil indicator shows whenever the generator needs more oil. This makes it easier for the customer to refill it as you don’t have to keep checking the oil level.

The engine shuts off as soon as there is a shortage of oil. This is a protective measure to ensure the equipment can operate efficiently.

The circuit break mechanism of the generator prevents overload during a fault and ensures the safe functioning of the equipment. It also has a receptacle for the 30A RV cord in case you want to use it. This would help you fulfill your power needs better.

The noises created by generators are a nuisance, especially when someone is trying to sleep. The Firman P03603 4550 is specially designed to ensure that the customer has a noiseless experience. The P03603 is Canada Emissions certified and is safe for the environment.
