Exchanging springs
Gently turn the adjustment knob for the pre-
load on the adjustment unit (9) clockwise as
far as it will go.This causes the spring to relax.
Place a matching spanner or an adjustable
wrench on the two parallel surfaces of the
pre-load adjustment unit.Then remove the
entire unit by turning it anti-clockwise.
Carefully remove the springs with one finger
or the head of a spoke from the fork.
Alternately put your bicycle upside down and
catch the springs when they fall down.
Exchange the springs, lightly grease all parts
and assemble the fork again in reverse order.
After having finished the assembly please check
if the fork works properly by compressing it
several times manually.

Lubricating the fork / Dismounting
In order to lubricate the fork have your bicy-
cle mechanic dismount it completely.
First remove the pre-load adjustment unit and
springs as described under "Exchanging
springs".
If your spring has an adjustable damping (M
EKS
Carbon AC) turn the knob clockwise as far as
it will go so that the fork does not decom-
presses again.
Undo and remove the screw M6 on the lower
part of the leg (18).To prevent the push rod
(14) from turning too press the fork together
entirely and hold the push-rod with a long
Allen key SW5.
At the suspension fork M
EKS Carbon All per-
form the same work on the second spring
strut. Now you can pull the upper part of the
fork out of the lower part.
At the suspension fork M
EKS Carbon AC re-
move the screw on the lower part of the leg
(19). Usually the damping cartridge (3) does
not turn. However, when you have difficulties
in removing the screw you can fix the cartrid-
ge in the upper leg with a screw driver and
thus prevent it from turning too. For this pur-
pose, undo the entire damper adjustment unit
by placing a wrench on the cap (8). Caution:
Never disassemble the adjustment unit (4, 5, 6,
7, 8)!
Clean all parts with a cloth. Grease the bus-
hings, legs, springs and threads thoroughly and
assemble the fork again.
After you have relaxed the pre-load unit of the spring you can
turn off the entire unit.
