Firstly, you should make sure that you use the correct equipment. That means wearing safety goggles to protect your eyes from flying wood splinters, protective shoes (boots with toe caps, for example), and no loose clothing. Only one person should use the kinetic log splitter at a time. If the machine starts to work before everyone is ready, it can be hazardous. You should also ensure that nobody is standing too close to you as you use the log splitter. You should make sure the log splitter is placed onto study, even ground, and you should block the wheels from moving using wood or something similar - basically, you want to ensure that the recoil doesn't cause the log splitter to lurch forwards. Another thing to do is make sure you read the instruction manual thoroughly before you begin. This way, you'll know exactly what to do to use it safely.
