CHAPTER 4

MAINTENANCE

This chapter provides information that is needed in basic

maintenance of the product.

Periodic Maintenance

Testing Proper Operation

It is recommended to check the ball bearings of the

anemometer and the vane every year. If the cup wheel or the

vane is not rotating smoothly or it creates detectable noise,

the bearings must be replaced.

Replacing Consumables

Only a trained technician should replace the bearings.

If your sensor includes the alignment sleeve and the factory

alignment has not been altered, you can simply remove and

remount the sensor to its place with the plastic collar

without realigning.
