Using this turntable clamp is easy. First, place your record on the turntable. Then, position the clamp over the spindle and use the metal screw knob to tighten it. This will apply pressure to flatten the record. When using it, keep in mind that it won't fix warped records. For maintenance, you can use a soft, dry cloth to wipe the clamp occasionally. Store it in a dry place to prevent any damage to the POM polymer body.
