1) Push the wind cups onto the
smaller of the two stainless steel shafts at the end of the
arm.
2) Slide the wind cups up as far as possible.
3) Use the Allen wrench provided to tighten the set screw on the
side of the wind cups. When you let go of the wind cups, they
should drop slightly
4) Spin the wind cups. If they do not spin freely, loosen the set
screw and lower the cups slightly. Repeat until the wind cups spin
freely.
Note: DO NOT attempt to lubricate the wind cup
shaft and bearings or the wind vane shaft. Natural or synthetic
lubricants affect the normal operation of the anemometer by
reducing the components’ efficiency. They may also attract insects
which can interfere with moving parts.
