SunStar HC Series - Adjusting Driver Belt Tension; Y-Axis Timing Belt

6-11-1) Specification of Drive Belt Tension Adjuster
6-11-2) Y-Axis Timing Belt
6-11) ADJUSTING DRIVER BELT TENSION
① Push the X frame plate to the driven pulley ([Fig.6-22]) and check the drive belt tension on the Y-axis. Use the
sound wave tension gauge.
② Tension on the Y-axis belt should measure as below on the sound wave measurer when you pluck the middle of
the belt between the end of the X frame connecting plate and the drive pulley with your finger.
③ Input data for the sound wave tension measurer:
① Model: U-305 Series Sound Wave Belt Tension Gauge - Standard
② Manufacturer: UNITTA
④ To adjust the tension on the Y-axis timing belt, unfasten the tension base screws. Turn the bolts to adjust the
tension. Turn clockwise to increase and counterclockwise to decrease the tension.
[CAUTION]
1. Drive belt tension can be adjusted only by trained SWF engineers.
2. Make sure to turn OFF the machine during the adjustment.
