Build the relay lever
Install the largest pivot pin and tighten to 28 Nm. Fit the ball stud with the supplied locknut at 8 Nm. Snap on the rectangular friction piece and lubricate it with synthetic grease. Grease the primary lever’s slot.

Choose cable posts
Select posts that fit the cable ends without play. Loosely fit the posts to both levers with their locknuts. Begin with approximately the original post-to-pivot distances; leave these nuts loose for subsequent adjustment.

Fit the weights
Choose the inertia weights and corresponding screw length. Screws must not protrude beneath the primary lever. Tighten the 4 mm hex screws to 2 Nm. Very short relay-lever positions can prevent use of all three weights because of cable interference.
