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, dry cloth to remove dust and grime. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish or internal mechanisms.
• Lubrication: If the dials become stiff or difficult to turn, 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 dirt and dust.
• Storage: Store the lock in a dry environment when not in use to prevent corrosion, especially if exposed to moisture during travel.
• Avoid Force: Never force the shackle or the dials. If you encounter resistance, recheck your combination or apply lubrication.

Troubleshooting

If you encounter issues with your Master Lock 4688D, refer to the following common problems and solutions:

• Lock Will Not Open with Correct Combination:
  • Ensure each number in your combination is perfectly aligned with the indicator marks.
  • Try rotating the dials slightly past your combination and then back to ensure proper alignment.
  • Verify that the combination has not been accidentally reset. If unsure, try the factory preset (0-0-0) or any other combination you might have set.
  • Apply a small amount of lubricant to the dials and shackle mechanism, then try again.
• Shackle is Stiff or Difficult to Insert/Remove:
  • Ensure the combination is correctly set before attempting to open or close the lock.
  • Check for any obstructions or debris in the shackle holes or around the shackle itself.
  • Apply a graphite or silicone-based lubricant to the shackle and its entry points.
• Forgot Combination:
  • Unfortunately, if you have forgotten your combination and did not record it, there is no master reset code for user-set combination locks. The lock will need to be replaced.
  • For future reference, always record your combination in a secure, memorable location.
