Steel Scorpion Coaster

General Tips

• Orientation of parts - Be sure to check and re-check orientation of blue and gray connectors. If you are unclear of the orientation on one page, go to next page to see what hooks into the pieces in question - this will help you place them correctly.
• Track pieces - Connectors should attach to the track pieces with a firm snap. This will happen each time if you are sure to have each track piece oriented as the page clearly shows before attaching the connectors. If your track pieces keep popping off after you have attached them to the main structure, it is likely you have not "snapped" the connectors onto the correct side of the track.
• Chain – Be sure that your chain is threaded through the track pieces in the proper spots at the top and bottom gears.  Chain that is not threaded properly may be too tight and break or bind (you will hear the motor clicking), or be too loose and not pick up the car properly.  Your chain may also occasionally get caught on the black Chain Guides. When this happens the chain will stop moving and you will hear the motor clicking. Simply re-position the Chain between the Guides to stop the problem. Also, be sure to count and make sure you have the appropriate number of chain links put together. You may actually get a piece or two more included in the bag than what is called for in the instructions!
• Car – If your car is slipping or getting stuck at the “elbow” along the chain, try moving the third chain guide (counting down from the number “31” on page 27) to the track bar (cross piece) just below the joint where the two tracks meet.  This should smooth out the ride of the car as it goes up the hill.
