2. Adjust initial spring length.
a. Make sure that the brew-lever is in resting (upper) position.
b. Insert one special tool on one side of the adjustment ring (see arrow in
), the
other tool on the opposite side.
c. To increase pressure turn the adjustment ring down (clockwise as seen from above) while
exerting even momentum on both special tools.
d. Check the maximum water pressure of the group again (see above).
Caution!
Over-shortening of the spring will lead to serious damage to the lever mechanism.
When the spring gets shortened too much, the individual coils will touch each other and it
may be difficult, if not impossible, to get the brew-lever into locking position. When you
encounter more than usual resistance before the brew-lever locks, turn the adjustment
disk a little upwards until locking is easy again. Then adjust the other group(s) by
decreasing its (their) initial spring force.
e. Adjust initial length again if not yet satisfactory.
