1. Compression damping force adjusting bolt
(for fast compression damping)
2. Compression damping force adjusting bolt
(for slow compression damping)
Compression damping force (for fast
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).
INSTRUMENT AND CONTROL FUNCTIONS
Compression damping setting (for
fast compression damping):
Minimum (soft):
4 turn(s) in direction (b)*
Standard:
3 turn(s) in direction (b)*
Maximum (hard):
0 turn(s) in direction (b)*
* With the adjusting bolt fully turned
in direction (a)
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).
Compression damping setting (for
slow compression damping):
Minimum (soft):
20 click(s) in direction (b)*
Standard:
9 click(s) in direction (b)*
Maximum (hard):
1 click(s) in direction (b)*
* With the adjusting bolt fully turned
in direction (a)
3-34
TIP
To 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.
WARNING
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.
 Do not tamper with or attempt
to open the cylinder assembly.
 Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.
 Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
