The left and right spring preloads must be
adjusted to the same setting. Uneven set-

stability.
The spring preload of the sliding frame exten-
sion can be adjusted by turning the adjusting
nuts.
To increase the spring preload, turn the ad-
justing nut in direction (a). To decrease the
spring preload, turn the adjusting nut in direc-
tion (b).
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
