2. Fully close the damper while turning the dust
cap or piston rod slowly CCW until it is felt
that the cams of the adjusting nut engage in
the recesses of the foot valve assembly
(Figure 26).
NOTE
In figure 23, if there is an indentation (B) in the
dust cap (C) and the cover shows two holes
(A), the damper is fitted with a bump rubber
(D). If so, fully extend the damper and insert a
round bar or screwdriver through the holes.
Push the bump rubber down and remove.
Remove the split plastic collar (E) (if fitted)
from the piston rod.
3. The damper may have already been
adjusted. Therefore check whether the
damper is adjusted or not by keeping it
closed and gently turning further CCW,
counting at the same time the half-turns until
a stop is felt. Stop turning and do not force.
4. While keeping the damper closed, make two
CW half-turns. In case of prior adjustment,
add the number of half-turns previously
counted. The total range is about five half-
turns. Pull the damper out vertically without
turning for at least 3/8” (1cm) to disengage
the adjusting mechanism. The dust cap or
piston rod may now be turned freely.
5. The damper can now be refitted in the
vehicle.

panel hinge cover.
