The core of jointer consists of a round cutter head with many carbide inserts. The cutter head is driven by an electric motor. The table is made from multiple pieces to control the material being fed into the machine. The front table can be adjusted up and down to control the amount of material that is exposed to the cutter head. The lower the table the more material per pass will be removed. There are a few other things to keep in mind regarding your material as well. Make sure the material you are cutting is free of all foreign objects. Do not cut materials that may have nails or screws as they will damage the blade and may cause injury to you. Also, if the material contains a loose knot it can break free and create a safety hazard.
If your material looks good, the next step is to set up the jointer itself. When setting up the jointer table, make sure not to remove more than 1/16" of material. This limits the amount of cutter engagement and will help prevent a kickback. You will also want to hook up the adjacent dust collector to the end of the machine, make sure it is plugged in, and turned on. The dust collector must be used with the jointer to help keep the dust out of the air. As you make a cut, it is imperative that you keep the wood firmly against the fencea and tabe. Therefore, you should double check to see if you are reading the right measurement on the fence, especially because the fence can be moved to either side of the blade which is why there are two distance indicators, only one of which is correct for each set up. Make sure to ask the supervisor about the available jigs because they can be helpful for specialty cuts. Once the supervisor has demonstrated the use of a jig feel free to use it in the future but do not play around with jigs you are unfamiliar with.
After the saw is set up you are ready to cut. Turn on the saw and slowly push the material through, making sure to keep your hands away from the blade. Do not stop pushing the material until after the cut is finished unless there is an emergency, in which case, carefully use one hand or your hip to bump the off switch. Also not let go of your work piece during the cut or it will be forced back towards you.
