Below you will find a picture of my Barco plus copies of the manuals I received with it. Feel free to copy any of the manuals. (If you have found this page useful I would appreciate hearing from you)

A fine tool from the past
Many years ago I worked at a local cemetery. One day while cleaning out an old storage building I found a Barco gasoline powered jackhammer. I was told that the cemetery used it in the late 40's to jackhammer through frost and for tamping dirt and sod. I really didn't know much about it but it did look interesting. It was going to the scrap yard so I asked if I could purchase it. To my surprise they gave it to me along with the manuals. It didn't take long to get it running. I have used the Barco on a few occasions and find it really does work and is quite simple to operate. Just fill the gas tank with the proper fuel/oil mix, connect the ignition to a 6 volt battery, turn on the fuel, push the rod at the top down and release and hang on!

How it works:
The Barco consists of a piston, cylinder and ignition system. There is no crank shaft, connecting rod or valves yet it is a gasoline engine. The principle behind the Barco is quite simple. When the spark plug fires it drives the piston to the bottom of the cylinder. During it's travel down the piston draws in fresh fuel/air and expels the exhaust. At the bottom the piston hits the anvil and a heavy spring. This spring pushes the piston back to the top, compressing the fuel/air mix. The spark plug fires and the process repeats.

These pictures are of a Barco Pegson Rammer BR451 that was rescued from a scrap pile. The man who found it contacted Barco and was told that the division that made these rammers had been bought out by the "Stihl" Company. If anyone has any information about this machine please email me
