Revision 3
While holding the stationary base in one hand, quickly
spin the revolving turret multiple times in both
directions with the other hand, to drive out any excess
grease from beneath the threaded retaining ring. Use
dry cotton swabs to remove any grease squeeze-out
(see
Figure 28 ). Do not use a solvent here, otherwise
the solvent may run into the revolving turret
mechanism and foul the grease within.

Apply Grease to the Center-Pivot Bore
Apply a small amount of grease (item S2 of Appendix 1 )
into the center-pivot bore of the stationary base for the
¼” bearing ball (see Figure 29 ).

Reinstall the Center-Pivot Bearing Ball
Now that the center-pivot bore has been greased,
reinstall the
¼” bearing ball into the freshly greased
center-pivot bore. The grease will hold the center-pivot
bearing ball in the proper position during subsequent
reinstallation of the pivot-adjustment screw (see
Figure
30 ).

Apply Grease to Top of the Center-Pivot Ball
Apply a small amount of grease (item S2 of Appendix 1 )
onto the top of the ¼” bearing ball in the center-pivot
bore (see Figure 31 ).

Reinstall the Pivot-Adjustment Screw
Use a suitable slotted screwdriver to reinstall the pivot-
adjustment screw into the threaded bore in the center
of the stationary base (see
Figure 32 ). Carefully snug
the adjustment screw just to the point where a slight bit
of resistance is felt. Test the feel of the revolving turret.
If the motion feels rough, back the screw off a bit until it
feels smooth. Leave the screw in this position.
