9 Installation of Mechanical Override Models
7 Installation of Mechanical Override Models
5. Attaching the Lever Handle to the Lock (with the key
as shown in Fig. 6 & Fig. 7)
7. Fit the lever handle (H) onto the drive tube (E) see page
34. It should rest approximately 1/16" from the body of the
housing. If not, wiggle and jiggle key (N) to align cylinder
(J) with override shaft (L)(See Fig. 8)
If it can’t be pushed that close to the housing, the lever catch
(F) is probably not pushed in. Push it in. (see fig 2 page 35)
If the lever catch (F) is stuck, the override shaft (L) is in the
wrong position. (see fig 2 page 35) The two small indents
(M) on the cross of the override shaft (L) must be vertically
aligned as in fig 2 page 35

8. Press the lever (H) firmly against the housing while turning
the key (N) counterclockwise (this applies to both right-

position. (Fig. 9)

If it is not possible to turn the key (N) counter-clockwise to
complete this step, the spring washer (D, see page 34) may
be too tense: (Not for lever feel)
Hit the lever carefully with a rubber mallet to loosen the
spring washer (D). (you may
want to cover the lever handle
(H) with a cloth or other material to protect the finish of
the metal)
9. Remove the key (N). The lock will look as shown in Fig.10.

Gently check the rotation of the lever handle (H). It should
easily rotate approximately 45º.
Troubleshooting:
Right-handed Lock: Turn the lever handle (H) clockwise
without forcing it. If it stops at approximately 15º,
it was not assembled correctly as shown in step 4
(Fig. 6 & 7). Do not try to force it to turn. Release the
lever handle (H). Insert the small screwdriver (T, page
34) into the small hole on the underside of the lever
handle (H) and push in the lever catch (F) see page 35.
Re-do steps 2, 3, 4 & 5.
Left-handed Lock: Turn the lever handle (H) counter-clockwise
without forcing. The drive hub (B) (Fig.12 page 38) should not
rotate when the lever handle (H) is turned. If it does, it was not
assembled correctly as shown in step 4 (Fig. 6 & 7). Release
the lever handle (H). Insert the small screwdriver (T, page
34) into the small hole on the underside of the lever handle
(H) and push in the lever catch (F). Re-do steps 2, 3, 4 & 5.
