2.2. Ring cotters
In connection with the Vi rigging system, ring cotters are used for
the following items to prevent the respective item from slackening
and/or loosening:
–
Fixing bolt of the TOP and SUB cabinet's Rear links.
– Fixing bolt of the frame's Rear links and cable picks.
Function of the ring cotter
By default, the ring cotters are "locked" to prevent them from
loosening.
For modification reasons such as altering the position of the frame's
Splay link or exchanging a shackle, it may be necessary to
temporarily remove the cotter and reattach it afterwards.
For this purpose proceed as follows:
1. Unlock
Unlock the ring cotter by pushing up the front wire loop over
the straight wire shaft.
2. Release and remove
Push down the rear wire loop until the ring cotter snaps over
the edge of the bolt and remove the ring cotter.
3. Refit and lock
Refit the ring cotter by pushing the straight wire shaft through
the hole and pressing the front wire loop underneath the
straight wire shaft.
