Building Help --> BIG BALL FACTORY

Every once in a while, your red and yellow Balls may fly off the ramp instead of completing the loop. All you need to do is slightly shift the ramp section in towards the Big Ball Factory. It will not look like much of a movement, however, it may make a significant difference in controlling the Balls on the ramp.

The Ball pick-ups hooked to the Chain require one empty Chain Link in between the light gray Connector and the orange Connector. Without the one empty Chain Link, the Ball pick-up will not be able to carry the Balls to the top of the model.

To keep your Chain from coming apart as it rounds the red Gears, pay close attention to the picture on the right side of page 19 in the instructions. When the Chain runs along the outside of the Factory, hooks on each Chain Link should be pointed toward the floor with the open side of the hook pointing out, away from the Big Ball Factory.

If you notice that your Big Ball Factory Chain, built with 126 links, becomes too long (as it may over time), you can substitute one Gold Splicer ("T" shaped clip) for a Chain Link. Remember, gold Splicers are equal to 1/2 of a chain link. This will prevent your chain from dragging.
