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 
(se

Figure  28

).    Do  not  use  a  solvent  here,  otherwise 

the  solvent  may  run  into  the  revolving  turret 
mechanism and foul the grease within.   

 

Figure 28 

 Remove any grease squeeze-out 

Apply Grease to the Center-Pivot Bore 

Apply a small amount of grease (item S2 o

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

).

 Place bearing ball into the center-pivot bore 

Apply Grease to Top of the Center-Pivot Ball 

Apply a small amount of grease (item S2 o

Appendix 1

onto  the  top  of  the 

¼”  bearing 

ball  in  the  center-pivot 

bore (see 

Figure 31

). 

 

Figure 31 

 Apply grease to the top of the bearing ball 

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  (se

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.
