5. Operating the Coaster
Once assembled, the K'NEX Amazin' 8 Coaster features a motorized chain lift that propels the coaster car through its twists and turns. The motor requires 2 "AA" batteries (not included). Insert the batteries into the designated battery compartment on the motorized lift according to the polarity markings.
To operate, place the coaster car at the base of the chain lift and activate the motor. The chain will carry the car to the top, releasing it to travel down the track. Ensure the track is clear of obstructions for smooth operation.
