 +
 +  - Removing the left fine focus knob
 +  - Installing the baseplate.
 +  - Installing and aligning the motor drive assembly.
 +  - Installing the motor drive cover plate and fine focus knob.
 +

 +
 +===== Part 2 - Installing the Baseplate =====
 +

 +
 +[{{ ::​lv300_z_06.jpg?​300 |Figure 5: Center plate under focus knob}}]
 +
 +Locate the base plate, and if the Z-drive is attached to it as shown in figure 4, use the 7/64” Allen wrench to remove the horizontal adjustment screw that secures it to the base plate. Lift the front of the microscope up and slide the baseplate under the microscope so that the unit is centered under the left focus knob as shown in figure 5.
 +
 +===== Part-3 - Installing and Aligning the Motor Drive =====
 +
 +a) Locate the ASI fine focus motor drive and loosen the two vertical adjustment screws that secure the drive to the adjustment bar. (See figure 6 for location of the two vertical adjustment screws.) Using the 7/​64"​hex wrench, loosen the screws just enough so that the drive can slide easily in the groove in the adjustment bar.

Loosen the screw that is on the drive side of the flex coupler. Align the drive shaft on the ASI drive with the flex coupler, and slide the motor drive shaft into the flex coupler as shown in figure 7. Seat the tab on the adjustment bar into the tab on the base plate as shown. Use the Allen wrench to tighten the flex coupler as shown in figure 8. Install, but do not completely tighten, the vertical adjustment screw (figure 4) to hold the drive in place. Please Note: the baseplate may need to be moved to properly align the adjustment bar.
 +
 +c) Slide the motor drive up and down, forward and backward slightly while turning the left fine focus knob until it is in the position where minimum drag is felt on the right focus knob. Secure the motor drive into position by tightening the horizontal and vertical adjustment screws (Figures 4 & 6).
