Put the small arms near the spring and insert
the upper vices in the first coil available (see
fig. 3).
After having found the right position of the
spring on the bracket and after having ad-
justed the upper vices, block the adjustable
arms (fig.4) locking the screws behind the
case with the key supplied.
Compress the spring using the foot control le-
ver only to release the pressure that the spring
it-self exert on the cap.
Do not compress the spring completely (see
fig.5).
Remove the blocking cap form the shock
absorber unscrewing the nut. Discharge the
compression of the spring and replace the old
shaft with the new one.
Assembling
For assembling make the contrary operations
of the disassembling. Put the new spring in the
same position where the old one was. Press
the foot control lever in order to make the
spring stuck to the blocking cap.
Block the cap to the shaft of the shock absor-
ber screwing the proper nut.
Now the shock absorber is mounted, use the
foot control lever to release completely the
spring, then move the arms on the outside and
remove the shock absorber now reassembled
thanks to the machine GO 312.
