pension, turn the adjusting nut in
direction (b).
● To make the adjustment, use
the special wrench and exten-
sion bar included in the addi-
tional tool kit, which was
handed out separately at the

● The spring preload setting is
determined by measuring dis-
tance A, shown in the illustra-
tion. The shorter distance A is,
the higher the spring preload;
the longer distance A is, the
lower the spring preload. With
each complete turn of the ad-
justing nut, distance A is
changed by 2.0 mm (0.08 in).
