Final assembly is shown in Figure 6.

The plate and U-Bolts are not yet needed at this stage but doing this now may help avoid damaging wind
vane and wind speed cups later on. Handling of the sensor package with wind vane and speed cups
installed to install these bolts is more difficult and more likely to lead to damage.
2. Install wind speed cups
Push the wind speed cup assembly onto the shaft on the top side of the sensor package, as shown in
Figure 7 on the left side. Tighten the set screw, with a Philips screwdriver (size PH0), as shown on the right
side. Make sure the cup assembly can rotate freely. There should be no noticeable friction when it is
turning.

3. Install wind vane
Push the wind vane onto the shaft on the opposite side of the wind cups, until it goes no further, as shown
on the left side in Figure 8. Next, tighten the set screw, with a Philips screwdriver (size PH0), as shown on
the right side, until the wind vane cannot be removed from the axle. Make sure the wind vane can rotate
