Compression damping
ECA24350
Do not turn the adjuster forcibly beyond its
adjusting range.
1. Adjust:
• Compression damping
a. Turn the adjuster “1” in the direction of “a”
or “b” to make an adjustment.
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.
