Now that the four M2.6X25 pan-head screws and the

Remove Lock Ring for the Pivot-Adjustment Screw

The slotted lock ring for the pivot-adjustment screw

(see

Figure

12) can be difficult to remove unless the

proper tool is used. Do not attempt to remove the

slotted lock ring and pivot-adjustment screw unless you

have access to such a tool, since the slot in the lock ring

will likely be damaged if you use an improper tool,

making removal of the lock ring much more difficult

suitable tool for this task can be easily made by filing or

grinding a relief notch for the pivot-adjustment screw in

the center of the blade of a large slotted screwdriver, as

shown in

Figure

13. Note that if you decide to make

such a tool, be sure that the tip of the screwdriver you

select has a blade width matching the outer diameter of

the slotted lock ring, and that the thickness of the blade

is such that it will seat fully into the slot of the slotted

lock ring.

Figure 13 – Screwdriver modified to remove slotted lock ring

Before attempting to loosen the slotted lock ring, the

revolving turret must first be locked in position relative

to the stationary base, in order to allow for sufficient

torque to be applied to the slotted lock ring to loosen

Don't even think about using a pair of needle-nose pliers to loosen the

slotted lock ring. It will end badly if you do. Don't ask me how I know this.
