Ease any tight balance hole bushings with key
easing pliers.
Lift up the Key back 1 – 2mm and release. It
should fall down slowly by its own weight, without
sticking. For best results, key should fall more
slowly in dry conditions, and a little faster during
humid conditions.
If the key sticks then ease the balance hole. This
process must be done carefully until the key moves
with the desired ease, but is not too loose.
*Do not ease the front and back of the balance rail.
Only ease the sides of the hole by turning the
easing tool inside the key so that the flat surfaces
face front to back, then apply pressure to the hole.
*If the balance hole is loose on the pin, apply a few
drops of alcohol and water (Isopropyl 70%) to the
hole then set aside. Once it is dry, re-fit it to the
pin.
