[Model 8077](https://resources.sargentandgreenleaf.com/migration/knowledge/padlocks?hsLang=en#model-8077) # How do I open my 8077 padlock? ## When opening, precisely align the numbers of the combination and the index while viewing directly from the front. Viewing from either side while dialing the combination will automatically introduce alignment errors. **All new 8077 locks are shipped from the factory set to a single combination number of 25**: 1\. Turn the dial left (counterclockwise) four complete revolutions. On the fourth revolution, align the number 25 on the dial with the padlock’s opening index. 2\. Turn the dial right (clockwise) to align zero with the padlock’s opening index. 3\. Pull sharply on the shackle to open the lock. **Note:** If the lock fails to open at this factory setting, dial ½ number lower or higher to compensate for possible variation of the factory setting. For instance, you should try dialing to 24½ or 25½. **Once the padlock is set to a true three number combination:** 1\. Turn the dial left (counterclockwise) until the first number of the combination aligns with the opening index the fourth time. 2\. Turn the dial right (clockwise) until the second number of the combination aligns with the opening index the third time. 3\. Turn the dial left (counterclockwise) until the third number of the combination aligns with the opening index the second time. 4\. Turn the dial (clockwise) right until zero is aligned with the opening index the first time. 5\. Pull sharply on the shackle to open the lock. **To Lock:** After closing the shackle, the dial must be turned at least five complete revolutions in either direction to ensure it is fully locked.
