So far I have always split wood with the ax, but had to deal with increasing age thereafter, unfortunately, more and more get along with pain in the shoulder. So had an electric wood splitter ago. I opted for the Zipper ZI-HS5, because he was offered quite favorable. He is almost completely composed of said about 50 kg package is something unwieldy. You just have to attach the front legs and away you go. The first surprise for me is that the unit is on the ground fairly close. I would have expected much higher. So you have to actually go to the operation in a crouch. But is okay because you sure the wood does not have as high lift. To operate you have to push a button and pull a lever. If you let one lot no longer splits the unit - clear, so you do not put your fingers in between. Before the column one should allow the device to run three minutes hot - which is a bit annoying so I start as a compromise with a small wood. With some 50 cm can also be really long pieces of columns, where firewood is much shorter and the carriage all the way to the end goes back again and again and you have to sit and watch the carriage times quite a bit in the deadhead each. Not ideal but also relaxing ;-) 5 tons splitting power sounds only times very much. Unfortunately, the device is already running but not from 4 tons. Still sounds a lot, but creates larger pieces with forks in the middle is no longer so simple. Toll the wheels on one side and on the other side has a sturdy handle the device. So you can easily move through the area. If I were, I would curse lumberjack sure about the device. In my need of some 4-5 cubic meters in just right.
