To remove and install the 5-in-1 sensor wind cups:
- To remove old or broken wind cups from the sensor, secure fingers between the wind cups. Then, pull the base of wind cup assembly away from the sensor while securing the sensor with your free hand. TIP: Hold the sensor close to your body to maximize pulling strength. Caution: Broken edges of wind cup may be sharp.
- Line up the mounting hole on the replacement wind cups with the spindle on the sensor. TIP: Place one drop of light machine oil or spray lubricant on the spindle to ensure the anemometer will spin freely.
- Attach the wind cups by inserting the spindle onto the sensor. Apply pressure to ensure the wind cups are properly secured on the sensor.
