OPERATION AND CHANGING INSTRUCTIONS
MODEL CDL-3/CDL-3M, UL GROUP 2, GROUP 2M COMBINATION LOCK

TO OPEN:

Your lock may be set on a factory shipping combination, or it may be set on a true, three
number combination. To open a lock set on a factory shipping combination on 50, turn
the dial LEFT until "50" aligns with the OPENING INDEX the fourth [4] time. Now turn the
dial RIGHT until it comes to a complete stop. The dial should stop at about "86" indicating
the lock lock bolt has been retracted.
If your lock is set on a true, three-number combination, for example, 50-20-30, follow these steps to
open:
1. Turn the dial LEFT until the first number of the combination 50 aligns with the OPENING INDEX the
fourth time.
2. Turn the dial RIGHT until the second number of the combination 20 aligns with the OPENING
INDEX the third time.
3. Turn the dial LEFT until the third number of the combination 30 aligns with the OPENING INDEX the second time.
4. Turn the dial RIGHT until it comes to a complete stop.
If the dial does not stop, carefully repeat the entire opening procedure. Remember to dial exactly to number of the
combination with which you are working. Dialing even a small amount past a number you meant to stop on will cause
the lock to remain locked. This is part of the lock's mechanism security.
Note: The dial should stop between 80 and 100 depending on where the dial was splined at the factory indicating the
lock bolt has been retracted.
To RELOCK the combination lock, turn the dial FOUR complete revolutions to any NON-COMBINATION NUMBER.

CHANGE THE LOCK COMBINATION:

You will need the Yellow Zinc Color Change key [Part# CHKY-2030-000] in the figure to the right to access the lock
to change the combination.
To Change the combination, please first open the lock, with bolt fully retracted
(Refer to the [To Open] Section above)
If your lock is set on the factory shipping combination on 50:
Turn the dial LEFT until the number "50" aligns with the CHANGING INDEX the
fourth time. Go directly to the step titled "INSERT THE CHANGING TOOL".
If your lock is set on a time, three-number combination:
1. Turn the dial LEFT until the first number of the combination aligns with the
CHANGING INDEX the fourth time.
2. Turn the dial RIGHT until the second number of the combination aligns with the
CHANGING INDEX the third time.
3. Turn the dial LEFT until the third number of the combination aligns with the
CHANGING INDEX the second time.

INSERT THE CHANGING TOOL:

The profile of both the change key and the opening in the lock's cover allow the
change key insertion only when aligned correctly. It may be necessary to wiggle the
change key slightly in order to insert it to the point where the change key wing is
entirely inside the lock case and the key has fully engaged the lock case.
attempt to turn the change key until the wing is completely inserted and bottoms out
in the lock case. Once this is accomplished, rotate the key approximately ninety
degrees COUNTERCLOCKWISE (the only direction in which it will turn). A definite
release of tension inside the lock will be felt (SEE FIGURE AT RIGHT).
