Remove Lock Ring for Pivot-Adjustment Screw
The slotted lock ring for the pivot-adjustment screw
(see
Figure 8 ) can be difficult to remove unless the
proper tool is used. Do not attempt to remove the
slotted lock ring from the 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

.
A 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 9 . 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.

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 this. Don’t ask me
how I know this.
