9. Install and tighten the left-hand index mounting screw (for indexes with either
mounting screw slots or holes). Use one 8 - 32 x 3/16-inch screw for this step (use an
original mounting screw if it is the correct size and not corroded. Use the correct size
replacement screw, if required).
10. Tighten the right-hand index mounting screw.
Note To verify correct installation of the index to the ERT module housing, spin
wriggler clockwise, then counter-
clockwise (not more than one complete rotation).
Wriggler should spin freely with little or no resistance.
11. Slide the ERT cover (1) over the index and backplate (2).
Next, program the ERT module.
