  Verify the attachment of the lever handle 
Very 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, see page 12) into the  
hole on the underside of the lever handle (H) and push in 
the 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)

  Adjust the lever feel
If applicable, to reduce  the lever play, using the 5/64 allen key 
(P1), tighten the set screw (O1) while pushing the lever against 
the front housing. Make sure the lever rotates properly after 
tighting  the set screw (O1) See fig 10B.

 Test the movement of the lever handle 
(remove the key (N) in cylinder (J))
13. Turn the handle (H) clockwise (for a right-handed lock) or 
counter-clockwise (for a left-handed lock)
14. Release the handle (H) slowly. It should return freely to its 
horizontal position. (Fig.11)

   Test the mechanical override function 
(Complete all tests in Section 4, pages 14 & 
15 after lock is assembled on the door) 
* This test can only be performed when the lock 
  is not affixed to the door.
!
16. Without using the key (N), turn the lever handle (H) clock-
wise (for Right-handed locks) or counter-clockwise (for Left-
handed locks). The inside drive hub (B) should not rotate when 
the handle (H) turns. (Fig. 12)

17. With the lever handle (H) in the horizontal position, insert 
the key (N) into the cylinder (J) and turn it clockwise until it 
stops. (This applies to both Right and Left-handed locks, see 
Fig.13)

18. Let go of the key (N), and again turn the lever handle (H) 
clockwise (for Right-handed locks) or counter-clockwise (for 
Left-handed locks). Now the inside drive hub (B) should rotate 
in the same direction as the lever handle (H) when it is turned.
