Log Splitter: http://www.cnsuperpower.com/product/log-splitter/
Cnsuperpower offers an open-center, single-spool valve specifically designed for gas Forest King Log Splitter.

The main reason that you might need to adjust the speed of your splitter is to help the wedge break through harder timbers. In these cases, a faster speed will cut through the timber in far less swings and without blunting the wedge.

For gas-powered electric log splitters, the adjustments can be a little more complicated, but not much. They still utilize hydraulic pressure to split wood—up to 25 tons or more of force. Unlike manual log splitters, however, there is no lever or foot pedal to pump. The hydraulic force operates electrically under gas power. Because far greater horsepower can be applied, a greater amount of force is available to split wood. Electric models can be freestanding or cnsuperpower log splitters that are mountable to your cnsuperpower for easy mobility and greater pressure.

Rather than adjust the splitting wedge, which on a gas powered cnsuperpower is fixed, adjustments made to electric hydraulic models requires a change in pressure. On the inlet side of the hydraulic jack there should a cap, under which you will find a slotted screw. This screw, when turned, increases or decreases the pressure exerted upon the jack, providing more or less force. Check with the specific manufacturer’s recommendation, but a common technique is to turn the screw all the way clockwise to test what the motor will take. It may kill the engine, but it won’t do any damage. You are simply testing it out. Turn the screw back to find a happy medium to resume with the right pressure.

Adjustments can be made to both manual and cnsuperpower electric log splitters. For manual models, it is a matter of adjusting the position of the wedge, whereas for gas powered splitters, the pressure of the hydraulic jack must be adjusted. In both cases they are routine operations that allow you to adapt your work according to the size and density of the wood.
