4 Combination Safe Lock Instructions (6631, 6643, 6651, 6731)

OPENING THE LOCK

The opening index is located at the top of the dial ring.  Dial numbers to this mark when you want to open the lock.  The changing index is located at approximately 11 o’clock
on the dial ring. Dial numbers to this mark when preparing to insert the change key and when actually setting a new combination.  This lock is a precision mechanism, so extreme care must be used to align the combination numbers with the index.  Turn the dial smoothly and steadily. If, after turning the correct number of revolutions, any number of the combination is turned beyond the index when you meant to stop on it, the entire series of combination numbers must be re-dialed. Do not attempt to turn the dial back to regain proper alignment with a “missed” number.  Each time a selected number is aligned with the opening index, a revolution is counted.

To unlock a true 4 number combination

1. Starting anywhere, turn the dial right (clockwise), stopping when the first combination number comes to the opening index the FIFTH time.
2. Turn the dial left (counterclockwise), stopping when the second number comes to the opening index the FOURTH time.
3. Turn the dial right, stopping when the third number comes to the opening index the THIRD time.
4. Turn the dial left, stopping when the fourth number comes to the opening index the SECOND time.
5. Turn the dial slowly to the right until it comes to a positive stop, indicating the bolt has retracted.
