Maintenance

The Master Lock 630D is designed for low maintenance. To ensure smooth operation and prolong the life of your padlock:

• Keep the dials clean and free from dirt or debris.
• Periodically apply a small amount of silicone lubricant to the shackle mechanism if it becomes stiff. Avoid oil-based lubricants as they can attract dirt.
• Store the lock in a dry environment when not in use to prevent corrosion.

Troubleshooting

Lock Will Not Open with Correct Combination

If the lock does not open after entering the correct combination, try the following:

• Ensure each number on the dials is perfectly aligned with the indicator line. Sometimes a slight misalignment can prevent opening.
• Gently jiggle the shackle while entering the combination.
• Double-check that you are using the correct combination. If you recently reset it, ensure you are using the new code.
• If the lock has been exposed to extreme conditions (e.g., dirt, moisture), clean the dials and shackle area thoroughly and apply a lubricant.

Shackle is Stiff or Difficult to Move

• Apply a silicone-based lubricant to the shackle where it enters the lock body.
• Ensure the combination is correctly set to 0-0-0 (or your current combination) before attempting to open or reset.
