Important: Turn dial slowly and evenly. Do not turn back to regain alignment if you rotate past number. If an error is made, re-dial entire combination. Do not count turns. Count how many times each number is aligned with the opening index (at the 12 o’clock position). Always view the dial and ring straight on, not at an angle.

CAUTION: The dial should not be pushed in until the combination has been dialed and the dial returned to zero at the opening index.

Use the following procedures to open a lock set on combination 50-25-50:

1: Turn dial left, past 50 three times stopping on the fourth time you come to it.
2: Turn dial right, past 25 two times stopping on the third time you come to it.
3: Turn dial left, past 50 once stopping on the second time you come to it.
4: Turn dial right stopping at “0.”
5: Hold the dial with “0” aligned with the opening index, push the dial in firmly, then release it to activate the lever assembly.
6: Turn the dial to the right until it stops. The bolt is now fully retracted.
