5.3.1 Install Wind Vane

Reference Figure 2. (a) Locate and align the flat key on the wind vane shaft to the flat key on the wind vane and push

the vane on to the shaft. (b) tighten the set screw with a precision screw driver and make sure the wind vane spins

freely.

Note: You may need to back out the set screw first before sliding the vane onto the shaft.

Note: The wind vane shaft does not spin as freely as the wind cups. This is by design. The dampening prevents

the wind vane from spinning with the slightest breeze, which will result in variable wind all of the time. The added

resistance allows the wind vane to change direction with 2 – 3 mph, providing a much better wind direction tracking.
