TIP ~~~~~~~~~~~~~~~
Although the total number of tu rns of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
turns always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of turns of
each damping force adjusting mechanism and
to modify the specifications as necessary.
