Knowledge base 165: Fitting Aperio H100 Handleset - Spindle alignment
Occasionally you can have a problem fitting the spindle into the H100 handleset.
Please check that the spindle lock is correctly aligned as shown below -
The bottom of the recess where the spindle fits should be
shaped to match the end of the spindle with the chamfers at the top
If the section at the bottom is not correctly aligned, e.g.
Use a small screwdriver to rotate
the end section to the correct alignment, then insert the spindle until it
clicks and locks in place.
