Setup
- Unpack Contents: Carefully remove the Kryptoflex 1018 lock and its two keys from the packaging.
- Identify Components: Familiarize yourself with the cable, the lock head, the keyhole, and the sliding weather guards.
- Test Keys: Insert one of the keys into the lock cylinder and turn it to ensure smooth operation. The key should turn easily to allow the cable end to be inserted or removed.
Operating Instructions
To Lock Your Bicycle:
- Position Bicycle: Place your bicycle next to a secure, fixed object such as a bike rack, lamppost, or sturdy fence.
- Route Cable: Thread the flexible cable through the frame of your bicycle and around the fixed object. For added security, also route the cable through one or both wheels if possible.
- Insert Cable End: Take the free end of the cable and firmly push it into the opening on the lock head until you hear a distinct "click." This indicates the lock is engaged.
- Verify Lock: Gently pull on the cable to ensure it is securely fastened and cannot be pulled out of the lock head without the key.
To Unlock Your Bicycle:
- Insert Key: Slide open the weather guard covering the keyhole. Insert one of the provided keys fully into the lock cylinder.
- Turn Key: Turn the key clockwise (or counter-clockwise, depending on the lock's orientation) until the cable end is released.
- Remove Cable: Pull the cable end out of the lock head.
- Remove Key: Turn the key back to its original position and remove it from the lock. The weather guard should automatically close.
Maintenance
- Lubrication: Periodically apply a small amount of graphite-based lubricant or a specialized lock lubricant into the key cylinder. Avoid oil-based lubricants as they can attract dirt.
- Cleaning: Keep the lock head and cable clean from dirt and debris. Use a soft cloth to wipe down the exterior. If the lock mechanism feels stiff, a blast of compressed air can help clear out dust.
- Weather Guards: Ensure the dual sliding weather guards are functioning correctly to protect the cylinder from the elements. If they become stiff, a light application of silicone spray can help.
- Storage: When not in use, store the lock in a dry environment to prevent corrosion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Key does not insert or turn smoothly. | Debris in cylinder, lack of lubrication, bent key. | Clean keyhole with compressed air. Apply graphite lubricant. Do not force a bent key; use the spare. |
