Setup

The Master Lock 1530DCM padlock comes with a pre-set, non-resettable 3-digit combination. This combination is typically found on a sticker on the back of the lock or on the packaging. Keep this combination in a safe and memorable place.

Identifying Your Combination

1. Locate the Combination: Check the packaging or a sticker on the back of your padlock for the factory-set 3-digit combination.
2. Record Your Combination: Write down your combination and store it securely. Do not store it inside the locker or item you are securing.

Operating Instructions

Opening the Padlock

1. Clear the Dial: Turn the dial three or more full turns to the right (clockwise) to clear any previous numbers.
2. First Number: Stop at the first number of your combination.
3. Second Number: Turn the dial to the left (counter-clockwise), passing the first number once, and then stop at the second number of your combination on the second pass.
4. Third Number: Turn the dial to the right (clockwise) and stop directly at the third number of your combination.
5. Open Shackle: Pull up on the shackle to open the lock. If it does not open, repeat the steps, ensuring precision with each number.

Closing the Padlock

1. Insert Shackle: Push the shackle firmly into the lock body until it clicks into place.
2. Scramble Dial: Turn the dial several times to scramble the numbers. This secures the lock and prevents unauthorized access.

Maintenance

Regular maintenance helps ensure the longevity and smooth operation of your Master Lock 1530DCM padlock.

• Cleaning: Wipe the lock body and shackle with a soft, dry cloth to remove dust and grime. Avoid harsh chemicals or abrasive cleaners.
• Lubrication: If the dial becomes stiff or difficult to turn, apply a small amount of graphite lubricant or a silicone-based spray lubricant into the shackle holes and around the dial mechanism. Do not use oil-based lubricants as they can attract dirt.
• Storage: Store the padlock in a dry environment when not in use to prevent rust and corrosion, especially if exposed to moisture.

Troubleshooting

Lock Will Not Open

• Incorrect Combination: Double-check that you are using the correct 3-digit combination. Refer to where you recorded it.
• Dialing Procedure: Ensure you are following the opening procedure precisely:
  • Turn right three full turns, stop at the first number.
  • Turn left past the first number once, stop at the second number on the second pass.
  • Turn right, stop directly at the third number.
• Over-Dialing: If you turn past a number, you must restart the entire opening sequence from the beginning.
• Stuck Shackle: Apply slight upward pressure on the shackle while entering the last number, then pull firmly.

Dial is Stiff or Hard to Turn

• Lubrication: Apply a small amount of graphite or silicone-based lubricant as described in the Maintenance section.
