Two-handed operation is an absolute must. This means that you have to operate one button or lever with each hand. This sounds awkward at first, but it is actually for safety. This guarantees that you don't have a free hand with which you can accidentally reach into the device and bruise yourself.
Another indispensable feature is an electrical start-up safety device. This prevents the machine from starting unintentionally when the current flows again after an interruption in the circuit.
Other important safety features are the following:
Safety emergency switch: when pressed, the log splitter stops immediately.
Hose covers: These prevent oil from leaking from the hydraulic lines.
Overload valve: It reduces the pressure when the splitting wedge hits material that is too hard, thus protecting the motor from damage.
