4. Maintenance

4.1 Cleaning the Wind Vane

Heavy contamination or obstruction in the vane, such as bird droppings or ice, deteriorates the

accuracy of the wind vane. Clean the vane if it is contaminated or there is an obstruction.

4.2 Testing Wind Vane Operation

The sensor holds its accuracy in all conditions for 1 year. If the rains are mostly casual and

moderate, and the atmospheric corrosion is typical, the sensor accuracy remains for 2 years.

Check the ball bearings and rotate the sensor shaft once a year.

1. Remove the vane assembly.

2. Make sure that the shaft spins smoothly and that there is no noise.

4.3 Replacing Consumables

Only a trained technician may replace the bearings.
