Jack Alignment, Height
Align jack
Align the back of the jack (nearest the hammers) to
the back of the wood core of the knuckle by turning
the jack screw in or out. When checking the
alignment, be careful of your eye angle to make
sure the jacks are aligned correctly.
Repetition Lever height
The top of the jack should be placed slightly lower
than the repetition lever (0.1 mm to 0.2mm).
When turning the regulating screw, depress the
repetition lever to avoid damaging the felt button
and pad.
To check repetition lever setting:
To check the repetition lever height, with the
hammer in the “rest” position gently and slowly
press down the jack heel. The hammer should
barely move. If it drops but doesn’t return when
the jack is released, then the repetition lever is too
low. If the hammer does not move when the jack
heel is pressed, then the repetition lever is too high.
