3. Betjeningsvejledning
The Thule 526 Lockable Knobs provide a simple and effective way to secure your bicycle to the carrier.
- Stramning af Clamp: Turn the knob clockwise to tighten the frame clamp around the bicycle frame. Ensure the clamp is firm but do not overtighten, as this may damage the bicycle frame or the carrier.
- Locking the Knob: Når clamp is tightened to the desired level, insert the key into the lock cylinder on the knob. Turn the key clockwise to engage the locking mechanism. The knob will then spin freely without tightening or loosening the clamp, preventing unauthorized removal.
- Unlocking the Knob: Insert the key into the lock cylinder and turn it counter-clockwise. This will disengage the locking mechanism, allowing the knob to tighten or loosen the clamp.
- Removing the Bicycle: Turn the knob counter-clockwise to loosen the frame clamp and carefully remove your bicycle.
Always remove the key after locking to prevent loss and ensure security.
4. Vedligeholdelse
Regular maintenance ensures the longevity and proper function of your Thule 526 Lockable Knobs.
- Rensning: Clean the knobs periodically with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners, which can damage the plastic and metal finishes.
- Smøring: If the lock mechanism feels stiff or difficult to turn, apply a small amount of graphite lubricant or a specialized lock lubricant into the keyhole. Do not use oil-based lubricants, as they can attract dirt and cause jamming.
- Inspektion: Regularly inspect the knobs for any signs of wear, cracks, or damage. Ensure the locking mechanism engages smoothly.
- Opbevaring: When not in use for extended periods, store the knobs in a clean, dry place.
