Using this mangle press is quite straightforward. First, make sure the press is placed on a stable and flat surface. You can then feed your items between the rollers and turn the handle to press them. When using, don't force overly thick or hard objects through the rollers to avoid damage. As for maintenance, regularly clean the cast - iron parts with a dry cloth to prevent rust. If you notice any looseness in the handle or rollers, tighten the relevant screws gently. Store it in a dry place when not in use to keep it in good condition.
