2. Setting Your Personal Combination
- Open the lock using the factory-set combination (0-0-0-0-5).
- Locate the reset button or lever on the lock head. This is usually a small button or a rotating piece on the side or bottom of the lock.
- Using a pen or a small pointed object, press and hold the reset button/lever.
- While holding the reset button/lever, set your desired 5-digit combination by rotating the dials.
- Release the reset button/lever. Your new combination is now set.
- Zvakakosha: Write down your new combination and store it in a safe place. Do not store it with your bicycle.

Operating Instruction
1. Securing Your Bicycle
For maximum security, follow these guidelines when locking your bicycle:
- Choose a Stationary Object: Always lock your bicycle to an immovable object that cannot be easily cut or lifted over, such as a dedicated bike rack, a sturdy pole, or a railing.
- Lock the Frame and Wheels: Prioritize locking the most valuable parts of your bicycle. Ideally, secure both the frame and at least one wheel (preferably the rear wheel) to the stationary object. The 120 cm length of the Kryptolok 912 chain provides flexibility for this.
- Create a Snug Fit: Minimize any slack in the chain to prevent thieves from using leverage to break the lock. The tighter the fit, the harder it is to tamper ne.
- Kuonekwa: Lock your bike in a well-lit, high-traffic area to deter potential thieves.

Maintenance
Regular maintenance will extend the life and functionality of your lock.
- Lubrication: Periodically apply a small amount of lubricant (e.g., silicone-based spray) to the combination dials and the locking mechanism to ensure smooth operation. This is especially important in dusty or wet environments.
- Kuchenesa: Keep the lock head and chain free from dirt and debris. Wipe down the protective nylon sleeve with a damp jira sezvinodiwa.
- Chengetedza Sleeve: The durable nylon sleeve protects your bike's paint finish from scratches and helps prevent the chain from getting dirty or rusty. Ensure it remains intact.
