10 DETACH/ATTACH OF TRIBRACH
The instrument is easily detached or attached to the tribrach, with a tribrach locking lever loosened or
tightened for this purpose.
● Detachment
1) Loosen the tribrach locking lever, by revolving it 180° or 200g in the counterclockwise direction
(which will point the triangle mark upwards).
2) Grip the carrying handle firmly with one hand while holding the tribrach with the other. Then lift the
instrument straight upwards and off.
● Attachment
1) Hold the instrument by the carrying handle, with one hand, and carefully lower it on top of the
tribrach while, at the same time, coinciding the alignment piece with the tribrach alignment groove
on the instrument and tribrach respectively.
2) When fully seated, revolve the tribrach locking lever 180° or 200g clockwise ( which will point the
triangle mark downwards again).
● Locking the Tribrach Locking Lever
The tribrach locking lever can be locked, to prevent it be accidentally removed, especially if the upper
instrument section is not being detached very often. Simply tighten the securing screw on the locking
lever with the accessory screwdriver, found in the case.
