From the Assembly Guide: "The two parts of the steering column are clamped together using the locking clamp, make sure the cut out faces the column, refer to Fig 29. Insert the grub screw loosely into the clamp. Secure the two halves of the clamp using two bolts , plain washers and spring washers. Torque to 14 Nm. Tighten the grub screw with an Allen key to eliminate any free play in the steering. Lock the grub screw into place using locknut." Jonathan
