Setup: Setting Your Combination
Your KryptoLok Combo U-Lock comes with a factory preset combination, usually 0000. To set your personalized 4-digit combination:
- Ensure the lock is open and the shackle is removed from the crossbar.
- Rotate the combination dials to the current opening combination (factory default is 0000).
- Locate the reset button or lever on the side or bottom of the lock body. Use a pen or small pointed object to press and hold the reset button, or slide the lever to the 'SET' position.
- While holding the reset button/lever, set your desired new 4-digit combination by rotating the dials. Make sure the numbers are aligned with the indicator marks.
- Release the reset button/return the lever to its original position. Your new combination is now set.
- Important: Test your new combination several times before locking your bike. Write down your combination and store it in a safe, memorable place, or register it with the Combo Safe Program.

Operating Instructions: Securing Your Bicycle
To effectively secure your bicycle, follow these steps:
- Choose a secure, immovable object to lock your bike to, such as a dedicated bike rack, sturdy pole, or railing.
- Position your bike close to the object.
- Enter your 4-digit combination to unlock the U-lock and remove the shackle from the crossbar.
- Pass the shackle through the frame of your bicycle and around the immovable object. If possible, also include one of your wheels (preferably the front wheel) within the shackle.
- Reinsert both ends of the shackle firmly into the crossbar until you hear a click, ensuring both sides are fully engaged.
- Scramble the combination dials to secure the lock.
- Gently tug on the lock and bike to confirm it is securely fastened and cannot be easily removed.

Mounting the FlexFrame-U Bracket
The included FlexFrame-U bracket allows for convenient transport of your U-lock on your bicycle frame:
- Identify a suitable location on your bike frame (e.g., seat tube, down tube) that does not interfere with pedaling or other components.
- Attach the bracket to the frame using the provided straps or bolts, ensuring it is tight and stable.
- Slide the U-lock into the bracket until it clicks securely into place.
- Ensure the lock is firmly held and does not rattle or obstruct your ride.

Maintenance
Proper maintenance will extend the life and functionality of your U-lock:
- Keep Clean: Regularly wipe down the lock body and shackle to remove dirt and grime.
- Lubrication: Periodically apply a small amount of graphite-based lubricant to the locking mechanism and combination dials to ensure smooth operation. Avoid oil-based lubricants as they can attract dirt.
- Dust Cover: Always use the rotating dust cover to protect the combination dials from environmental elements like dust, water, and debris.
- Vinyl Coating: The protective vinyl coating helps prevent scratches to your bike. Inspect it periodically for damage and avoid sharp objects that could cut or tear it.
