CAUTION
WARNING
IMPORTANT
To verify that the lever handle has been correctly attached
to the housing:
10. Remove key (N)
11. Insert a small flat screwdriver (tool T, page 18) into the
hole on the underside of the lever handle (H) and push
inthe lever catch (F) see fig 10A.
12. Pull on the lever handle (H).
You should not be able to remove the lever handle (H). If
it comes off of the housing, you did not assemble the lock
correctly. Return to steps 2, 3, 4 & 5 and make sure that
the lever (H) looks like Fig. 10 and repeat this verification
process. (Step 6)
