Unlocking a Master Lock depends on the type of lock (combination or keyed). Let's focus on unlocking a combination Master Lock based on the provided reference.
Here's a breakdown of how to open a typical combination Master Lock, especially if it's new:
- Enter the Combination: If you have a factory-new Master Lock, the default combination is usually 0-0-0-0. Dial the combination by aligning each number with the mark on the lock body.
- Pull the Shackle: Once the correct combination is entered, pull the shackle (the U-shaped metal bar) upwards to open the lock.
However, if you are trying to set a new combination (or unlock a lock after a new combination has been set, and you know the correct combination) the steps are as follows, according to the reference material:
- Turn the Shackle 90° (Position 1): After entering the known combination and pulling up the shackle, rotate the shackle 90 degrees to the first designated position. The reference refers to this position as "position 1."
- Push the Shackle Down (Click): Push the shackle down into the lock body until you hear or feel a click. This step is critical for setting or maintaining the combination.
- Turn the Shackle 90° (Position 2): Turn the shackle another 90 degrees to the second designated position, referred to as "position 2" in the reference.
Troubleshooting:
- Check the Combination: Double-check that you are entering the correct combination. Ensure that each number is aligned precisely with the indicator mark.
- Smooth Dialing: Make sure the dials turn smoothly. If they feel stuck or tight, try applying a small amount of lubricant (like graphite powder) to the dials.
- Shackle Movement: Ensure the shackle moves freely. If it is stiff, try gently wiggling it while pulling upwards.
