Adjustment Procedures
Adjusting of the pedal in accordance with the pedal type setting
Attach or remove setscrew 1 in accorance with the setting of
memory switch level 2 K01
™ 2-pedal and 1-pedal (without intermediate position) / Attach
setscrew 1.
™ 1-pedal (with intermediate position) / Remove setscrew 1.
Adjusting the pedal stroke
Pass the pedal connecting rod through hole B in the center.
When the rod is passed through hole A which is far from the
center, the whole pedal stroke is increased, and when it is passed
through hole C which is near the center, the stroke is decreased.
Fine adjustment of the pedal stroke
The pedal stroke can be finely adjusted by changing the position
of the detecting plate of the sensor.
Detecting plate 2 ........ The play at the start of depressing the
pedal can be adjusted in case of using 1-
pedal type. When detecting plate 2 is
lowered, the play is decreased, and when
it is raised, the play is increased.
Detecting plate 3 ........ Starting in case of using 2-pedal and 1-
pedal (without intermediate position) types
and lowering the presser in case of 1-
pedal (with intermediate position) type can
be adjusted. When detecting plate 3 is
raised, timing is advanced and when it is
lowered, timing is retarded.
Detecting plate 4 ........ S t a r t i n g t i m i n g o f 1 - p e d a l ( w i t h
intermediate position) type can be
adjusted. When detecting plate 4 is
raised, timing is advanced, and when it is
lowered, timing is retarded.
