-As shown in the above photos use the small knife, or shape instrument, to pry off the small round black cover located in the middle of the right fine focus knob.  Use the 7/32 or 5.5mm driver wrench to remove the nut that is located in the center of the fine focus knob.  It will be necessary to hold the left fine focus knob when removing this nut to keep the fine focus shaft from turning.  ​+As shown in the above photos use the small knife, or sharp instrument, to pry off the small round black cover located in the middle of the right fine focus knob.  Use the 7/32 or 5.5mm driver wrench to remove the nut that is located in the center of the fine focus knob.  It will be necessary to hold the left fine focus knob when removing this nut to keep the fine focus shaft from turning.  ​
  
 After the nut is removed remove the right fine focus knob by unscrewing it, counter clock wise, from the fine focus shaft.

-Please refer to the above photographs. Locate the ASI Drive assembly, if the unit has shipped with the knob and cover attached use the 1/​16” ​Allen wrench to remove the knob and cover as shown. ​ Loosen all of the adjustment screws, but do not remove them.  They should be loosened just enough so that the drive moves freely in all axis along the base plate. ​ Remove the clamp assembly from the left hand side of the base plate by removing the two screws that secure it.  Set the clamp and the screws aside as they will be used in the next step. +Please refer to the above photographs.

-Facing the front of the microscope hold the motor assembly in your right hand and slide the drive plate under the microscope. Align the hollow end of the drive shaft bearing so that it will slide over the drive shaft / gear assembly that you secured to the microscope’s fine focus shaft in step #1. Slide the drive in so that the drive gear mates with the encoder gear.  Push the drive completely onto the microscope so that the edge of the black base plate is against the side of the microscope. ​ Once the drive is completely pushed onto the microscope reattach the base clamp that you remove in step #2, and use the 5/​64” ​Allen Wrench to tighten the set screw in the base clamp assembly. ​ This will cause the silver press bar to squeeze against the side of the microscope and hold the drive assembly securely in place. ​ After the base plate has been secured insure that the gears are properly aligned and that nothing is binding or rubbing.  ​+Facing the front of the microscope hold the motor assembly in your right hand and slide the drive plate under the microscope.

-Turn the left fine focus knob and insure that there is no one spot with in the 360 degrees of rotation where any drag is felt. If you feel any drag,  slightly move the drive along the horizontal ( y axis ) and vertical ( z axis ) to a point where no drag is felt.  Since the drive is usually self aligning little or no movement in the x and y axis is required. ​ Use the 3mm and 7/64” Allen wrenches to tighten the adjustment screws, that were loosened in step # 2, at a point where no drag is felt. Recheck for minimum drag on the fine focus shaft by turning the right fine focus shaft. Repeat alignment procedure if necessary.+Turn the left fine focus knob and insure that there is no one spot with in the 360 degrees of rotation where any drag is felt.
