OPERATING INSTRUCTIONS FOR MECHANICAL LOCKS:
TO UNLOCK ON A SAMPLE COMBINATION OF 50 - 25 – 50
1. Turn the dial counterclockwise, stopping when 50 is aligned with the opening index the fourth time.
2. Turn the dial clockwise, stopping when 25 is aligned with the opening index the third time.
3. Turn the dial counterclockwise, stopping when 50 is aligned with the opening index the second time.
4. Turn the dial clockwise, stopping when 0 is aligned with the opening index the first time.
5. When 0 is aligned with the opening index, push the dial in firmly, then release it to activate the lever assembly.
6. Turn the dial farther clockwise until it comes to a positive stop near 85, indicating that the lock bolt has retracted. If the combination has been correctly dialed, the safe or cabinet may be opened.
This procedure can be used with any three number combination, substituting selected numbers for the numbers 50 - 25 - 50.
CAUTION: The dial should not be pushed in at 0 until all three numbers have been dialed and 0 is aligned with the opening index.
