Key Features

• Security Level 9: Offers good protection for bikes with a medium risk of theft.
• Hardened Steel Chain: 8 mm thick square chain made of specially hardened steel for enhanced resistance.
• 4-Digit Combination: Individually adjustable number combination for keyless convenience.
• Durable Number Rollers: 2-component number rollers ensure permanent legibility, preventing wear.
• Protective Textile Cover: Soft textile sleeve protects bicycle paintwork from scratches.
• Anti-Twist Protection: Prevents chain links from separating from the lock body.

Setup

Your ABUS 8808C chain lock comes with a factory-set combination, typically 0-0-0-0. It is highly recommended to change this to a personal, memorable combination immediately after unboxing.

Setting the Combination

1. Ensure the lock is open and set to the current combination (factory default is 0-0-0-0).
2. Locate the reset mechanism. This is usually a small button or a rotatable part on the lock body, often requiring a small tool (like a pen tip) to press or turn. Refer to the diagram below for its exact location.
3. With the lock open and the current combination set, activate the reset mechanism. For a button, press and hold it. For a rotatable part, turn it 90 degrees clockwise or counter-clockwise as indicated.
4. While holding the reset mechanism (or with it in the reset position), set your desired new 4-digit combination by rotating the number rollers. Choose a combination that is easy for you to remember but difficult for others to guess.
5. Release the reset mechanism (or turn it back to its original position). Your new combination is now set.
6. Important: Scramble the numbers immediately after setting your new combination to ensure it is correctly saved. Test the new combination to open the lock before securing your bicycle.

Operating the Lock

Once your combination is set, operating the ABUS 8808C is straightforward.

Opening the Lock

1. Slide the protective cover away from the number rollers to expose them.
2. Align the number rollers to your personal 4-digit combination. Ensure each number is precisely centered in the viewing window.
3. Pull the shackle or locking mechanism away from the chain link to open the lock.

Closing the Lock

1. Pass the chain through the frame of your bicycle and around a fixed object (e.g., a bike rack, lamppost).
2. Insert the locking mechanism back into the designated opening on the chain link until it clicks securely into place.
3. Scramble the number rollers immediately after closing the lock to secure it.
4. Slide the protective cover back over the number rollers to shield them from elements.

Maintenance

Proper maintenance will extend the life and ensure the smooth operation of your ABUS 8808C chain lock.

• Cleaning: Periodically wipe down the lock body and chain with a damp cloth to remove dirt and grime. Avoid harsh chemicals that could damage the textile cover or plastic components.
• Lubrication: If the number rollers become stiff or difficult to turn, apply a small amount of silicone-based lubricant or graphite powder to the mechanism. Avoid oil-based lubricants as they can attract dirt.
• Protective Cover: Always ensure the sliding cover is closed over the number rollers when the lock is not in use to protect them from dust, moisture, and wear.
• Storage: Store the lock in a dry environment when not in use to prevent rust and corrosion.

Troubleshooting

• Lock will not open with combination:
  • Ensure the numbers are perfectly aligned in the viewing window.
  • Double-check that you are using the correct combination. If you have recently changed it, try both the old and new combinations.
  • Apply a small amount of lubricant to the number rollers and try again.
• Number rollers are stiff or hard to turn:
  • Clean any visible dirt or debris from around the rollers.
  • Apply a silicone-based lubricant or graphite powder to the rollers.
• Lock mechanism feels sticky:
  • This could be due to dirt or lack of lubrication. Clean the mechanism and apply a suitable lubricant.
• Forgotten Combination:
  • Unfortunately, if the combination is forgotten and the lock is closed, there is no master key or backdoor to open it. You may need to contact a professional locksmith or consider replacing the lock.
