While holding Smaug's lower jaw in the highest position possible (as "closed" as possible), firmly press the
servo horn completely back onto the servo motor hub (figure E5).
IMPORTANT: DO NOT
allow the motor hub/
shaft to turn AT ALL as you reinstall the servo horn! Using the #2 Phillips screwdriver, install the retaining screw,
through the center of the servo horn, into the end of the servo motor hub. Tighten the screw until snug - DO NOT
OVERTIGHTEN!
7)
After reattaching the sculpture pieces and reinstalling the Smaug assembly in your game, use the Smaug
Mouth Test (figure E6) in the diagnostics menu to complete the jaw calibration process. For additional informa-
tion on running the Smaug Mouth Test and making jaw limit adjustments, see page B-21 of this manual.
WARNING:
NEVER attempt to move Smaug's jaw up or down when power is applied to the assembly (i.e., anytime the game is
powered ON); these actions can result in serious damage to the jaw crank link, servo horn or servo motor.
