Using the Crankcase robot toy is easy. First, if you want to convert it from robot to off - road vehicle mode, just follow the 14 - step process. When in vehicle mode, you can remove the front grill to get the large blaster accessory. The Energon blaster can be attached to the figure in both modes for more fun. When you get the toy, make sure to scan the code on the package right away to see the character tech specs. As for maintenance, keep the toy away from sharp objects to avoid scratches. Don't expose it to extreme heat or cold as it may damage the material. If it gets dirty, you can use a soft, dry cloth to clean it. Remember, other Legacy figures are sold separately, so if you want to collect more, check the availability.
