L-3   Resetting and Recovery of Current Combination

To reset the code gears (a), each one of the 5 “L” shaped 
legs (b) of the unlocking slide (c) must engage snugly 
with the corresponding code gear pocket (d) next to it.

 Position the chamber in one hand, as 
shown. Hold chamber by the top screw tab 
(e) and bottom screw tab (f). 
Rotate the reset cam (g) back toward you 
with your finger, towards the key stems (h) 
as far as it will go and then release.  Now 
look at the code gears (a) and the unlocking slide (c). Note 
that some or all 5 of the code gear pockets (d) are rotated 
away from the “L” shaped legs (b) as if out of alignment. 
Typically each code gear pocket will be at a slightly differ-
ent distance compared to the other.

   Note: Sometimes two different gear pockets are away from alignment by 

exactly the same distance – this indicates that the current combination uses 
two different number buttons (example, 2 and 4) depressed at the same 
time as part of the combination.

 Using a small flat blade screw driver or your thumbnail, depress the 
key stem which corresponds to the gear pocket which has been rotated 
the 

farthest away

 (out of alignment) from the “L” shaped leg. When 

depressed, the key stem(s) should stay down and the corresponding gear 
pocket(s) should move closer to its corresponding “L” leg, closer to align-
ment. Record the key stem number. This is the 

first

 number of your com-

bination.

 Continue by pressing the key stem that corresponds to the gear pocket 
that was the 

next furthest away

 (do not include gear pockets that have 

already been rotated). Record each key stem number that is depressed. 
Continue this procedure until all five gear pockets are aligned with their 
corresponding “L” shaped legs on the unlocking slide. The combination is 
the recorded numbers, in the order recorded.

   Note: If you depress the wrong key stem by mistake, rotate the reset cam  

back toward you, (toward the key stems and release). This resets the code 
gears and you must repeat the above procedure, L-3.
