Never turn an adjusting mechanism beyond
the minimum and maximum settings.

NOTE:
_
Although the total number of clicks of a damping
force adjusting mechanism may not exactly match
the above specifications due to small differences
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 adjust-
ing mechanism and to modify the specifications as
necessary.
