4.2. Instal·lació del sensor
Install the sensors one by one according to the indicated positions (FL, FR, RL, RR) on the side of each sensor. It is recommended to install them in the order of Front Left (FL) → Front Right (FR) → Rear Left (RL) → Rear Right (RR).
- Screw Valve Cap: Remove the original valve cap from the tire valve.
- Screw Anti-theft Nut: Screw the anti-theft nut onto the tire valve stem.
- Install Sensor: Screw the corresponding sensor onto the valve stem. Ensure it is tightened securely.
- Tighten Anti-theft Nut: Use the provided wrench to reverse rotate the anti-theft nut against the sensor, tightening it to prevent theft and ensure a secure fit.
- Comproveu si hi ha fuites: Apply soapy water around the sensor and valve stem to check for any air leaks. Bubbles indicate a leak, requiring further tightening or adjustment.
