Important: Turn dial slowly and evenly. Do not turn back to regain alignment if you rotate past the 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, (the mark at the 12 o'clock position).

To Open: (Refer to Figure A)

• Step 1: Turn dial left, aligning first number with the opening index the fourth time it comes to the opening index.
• Step 2: Turn dial right, aligning second number with the opening index the third time it comes to the opening index.
• Step 3: Turn dial left, aligning third number with the opening index the second time it comes to the opening index.
• Step 4: Turn dial right until dial comes to a complete stop.
• Step 5: To relock and secure the combination lock, turn the dial to the left at least four complete revolutions.

Changing Instructions for 6600/6700 series three number combination lock

Important: You must have the correct change key. Do not set the third number of the combination between 0 and 20 on a lock using a dial spindle splined at 50. Do not set the third number of the combination between 90 and 99 or 0 and 10 on a lock using a dial spindle splined at 41. Do not set adjacent numbers of the combination within five numbers of each other. Do not use strictly ascending (ex. 22-45-83) or descending (ex. 83-45-22) number sequences. Do not use combination numbers that will be easy for someone to guess. Do not use combination numbers that all end in 0 or 5. Do not remove lock cover. If an error is made, re-dial the entire combination.

To Change: (Refer to Figure B)

• Step 1: Using the existing combination on the opening index, unlock combination lock, and open safe door. Re-lock lock with safe door open.
• Step 2: Dial the existing combination again, using the changing index, (the mark at the 11 o'clock position). Keep the third number aligned on the changing index.
• Step 3: (Refer to Figure C) Insert change key into key hole on the lock's cover. Change key must be completely inserted.
• Step 4: Rotate key left (counterclockwise) 90 degrees.
• S tep 5: Enter a new three number combination using the changing index, dialing as follows:
• Turn dial left until the first new number aligns with the changing index the fourth time.
• Turn dial right until the second new number aligns with the changing index the third time.
• Turn dial left until the third new number aligns with the changing index the second time.
• Turn the dial right ten numbers.
• Step 6: Hold the dial steady, and rotate change key right 90 degrees until it stops. Remove change key.
• Step 7: Using the opening index, check new combination at least three times.

After changing the opening code, the lock should be opened and locked several times with the safe door open.

Important: Do not select codes such as birthdays or other predictable data which could give a correlation between the user and the opening code.
