Setup: Setting Your Combination

Your Master Lock 4688D comes preset to open at 0-0-0. Follow these steps to set your personalized combination:

1. Open the lock by rotating the dials to 0-0-0 and pulling up the shackle.
2. Rotate the shackle 90 degrees counter-clockwise from its open position.
3. Press the shackle down firmly into the lock body. While holding it down, rotate the shackle another 90 degrees counter-clockwise (total 180 degrees from open position).
4. Set your desired 3-digit combination by rotating the dials. Choose a memorable number.
5. Lift the shackle to its open position. The shackle will spring up.
6. Rotate the shackle back to its original open position (90 degrees clockwise).
7. Push the shackle down to lock it. Your new combination is now set.

Important: Write down your new combination and store it in a safe, memorable place. Master Lock does not retain combinations.

Operating Your Lock

To Lock:

1. Ensure the shackle is in the open position.
2. Pass the shackle through the zipper pulls or securing points on your luggage.
3. Push the shackle down into the lock body until it clicks securely.
4. Scramble the dials to a random number to secure the lock.

To Unlock:

1. Rotate the dials to your personal 3-digit combination.
2. Pull up on the shackle to release it from the lock body.

The TSA (Transportation Security Administration) can open your lock using a special key without damaging it, then relock it after inspection. This feature is indicated by the red diamond logo on the lock.

Maintenance

To ensure the longevity and smooth operation of your Master Lock 4688D, follow these simple maintenance guidelines:

• Cleaning: Wipe the lock body and shackle with a soft, damp cloth to remove dirt and grime. Avoid abrasive cleaners or solvents.
• Lubrication: If the dials become stiff, apply a small amount of graphite lubricant or a silicone-based spray lubricant to the moving parts. Do not use oil-based lubricants as they can attract dust and dirt.
• Storage: Store the lock in a dry environment when not in use to prevent corrosion.

Troubleshooting

• Lock will not open with combination:
  • Ensure the dials are precisely aligned with your set combination.
  • Verify you are using the correct combination. If you forgot it, unfortunately, Master Lock does not store user combinations, and there is no master key for consumer locks.
  • Try slightly wiggling the shackle while entering the combination.
• Shackle is stiff or difficult to operate:
  • Apply a small amount of graphite or silicone-based lubricant to the shackle mechanism and dials.
  • Check for any debris obstructing the shackle's movement.
• Dials are hard to turn:
  • Clean the dials with a soft cloth.
  • Apply a small amount of graphite lubricant to the dials.
