    228CFX - PianoCD - iQ Step 1: Disassemble the Piano A. Remove the music desk and the fallboard. On many pianos, the fallboard can be easily removed by lifting it upward and outward. On others, it is attached to cheek blocks at the ends of the keyboard. These blocks must be removed first, usually by loosening the long screws beneath the keybed.

    If a straight edge of appropriate length is not available, span the marks with • masking tape, tacky side towards the felt. This will cause the tape to adhere to the felt, thereby providing a straight edge for cutting. Figure 3 PianoDisc Installation Guide...

  • Page 14: Step 4: Keyframe Bedding

    228CFX - PianoCD - iQ Step 4: Keyframe bedding A. Before cutting the keyframe, determine if the material removed will change the keyframe bedding. In some pianos the keyframe has a raised edge on the material to be removed. There may also be keybed recessed areas. The material removed from the keyframe and keybed could change the keyframe bedding and cause many adjustments to be affected.

    228CFX - PianoCD - iQ Step 12: Reinforce the keybed Note: If the keybed is sectioned (as in some Steinways) or if the keybed is less than 1 1/2” (38 mm) thick, we strongly recommend reinforcing the keybed after cutting the slot. In weaker keybeds, this will greatly improve the stability of the action regulation.

    The only correct remedy is to add cardboard shims to the bottom of the key rest felt. Step 32: Action regulation procedure The PianoDisc system will perform optimally when the piano action is operating at the manufacturer’s specifications. The following items represent a typical regulation checklist.

  • Page 56: Step 33: Action Installation

    228CFX - PianoCD - iQ Step 33: Action installation The design of the PianoDisc spring loaded solenoids requires the keys to be depressed, or the action to be lifted as the action is moved into position. This is necessary to ensure that the action clears the rubber tips of the plungers, thereby preventing damage to the plunger stems.
