Compression damping force (for slow
compression damping)To increase the compression damping
force and thereby harden the com-
pression damping, turn the adjusting
bolt in direction (a). To decrease the
compression damping force and there-
by soften the compression damping,
turn the adjusting bolt in direction (b).
TIPTo obtain a precise adjustment, it is
advisable to check the actual total
number of clicks or turns of each
damping force adjusting mechanism. This adjustment range may not exactly
match the specifications listed due to
small differences in production.
