You can equip this card to non-Machine-Type monsters on your opponent's side of field to prevent them from attacking; it is not usually advised to equip this on your own Monster Cards, despite occasional strategic benefit from this.
Using "DNA Surgery" and declaring any Type other than Machine will allow you to "paralyze" Machine-Type monsters.
This card can be useful in a Deck revolving around "Power Tool Dragon". It can be used defensively by equipping it to an opponent's monster. At the same time, it can still be equipped to "Power Tool Dragon", which grants it an extra invincibility but since it is immune to the setback, it can still attack.
