Page 23: Chapter 4 Maintenance
Chapter 4 ________________________________________________ Maintenance 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. - Page 24 User's Guide ________________________________________________________ To replace the ball bearings, do the following (the numbers refer to Figure 12 on page 23): Anemometer bearings: Loosen the hubnut (14) with fingers or a 10 mm tool and remove the cup wheel (13). Remove the ball bearing assembly (12) by unscrewing it counterclockwise (with a 10 mm tool).
