facing the same direction as the player's face.

1.
Loosen the bell screws. Firmly holding on
to the bell on both sides, rotate the bell
slowly while inserting the bell into the bell
joint on the main body. After the bell is po-
sitioned, tighten the three bell screws so that
each screw applies the same amount of
pressure against the bell.
* During rests, make sure that the bell
screws are tightened firmly.
Never loosen the screws on the copper
bracing holding the main coils together.
Doing so may cause the coils to separate
resulting in injury. Also, regularly check
that the attachment screws on the main
tubing are tightened firmly.
