a. Turn the adjuster “1” in the direction of “a”
or “b” to make an adjustment.
TIP
Although the total number of clicks of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
clicks always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of clicks of
each damping force adjusting mechanism and
to modify the specifications as necessary.
Compression damping (for fast compres-
sion damping)
NOTICE

Do not turn the adjuster forcibly beyond its
adjusting range.

Compression damping (for fast compression
damping)
a. Turn the adjuster “1” in the direction of “a”
or “b” to make an adjustment.
TIP
To obtain a precise adjustment, it is advisable to
check the actual total number of turns of the
damping force adjusting mechanism. This ad-
justment range may not exactly match the spec-
ifications listed due to small differences in
production.
