Adjust the Tightness of the LockJaw (The Adjustment Bolt)

The LockJaw is exceptionally stiff and stable, but will require period

inspection and adjustment to ensure that it is properly tensioned.

Adjust the LockJaw according to the following instructions.

Version A

Tools Needed: 6 mm Allen key

NOTE: Only turn the adjustment bolt in small increments (e.g. a 1/8

turn) each time otherwise you might over tighten or over loosen it.

Do not over tighten the adjustment bolt. Over tightening the

adjustment bolt will cause damage to the meshing mechanism, which

will eventually affect the functionality of the LockJaw and your safety.

Do not over loosen the adjustment bolt. If it is too loose, the

LockJaw hinge will not close tightly, which will result in a loose joint.

To tighten the adjustment bolt,

turn it as indicated by the arrow

(clockwise when looking at the bolt

head-on)

Adjust the Adjustment Bolt while the frame is closed.

To check the correct tightness of the LockJaw close and open the OC

bolt. When the OC bolt closes with a “click” at the end, the tightness is

just right.

Once you have achieved the correct tightness, close the LockJaw

by turning the OC bolt 180º counter-clockwise.

First open the OC Bolt

(turn 180º counter-clockwise)

But DO NOT open the frame

To loosen the adjustment bolt,

turn it as indicated by the arrow

(counter-clockwise when looking at

the bolt head-on)
