SunStar SWF/C-UK1504 - 11-12) Adjusting Drive Belt Tension; 11-12-1) Y-Axis Timing Belt

11-11
11-12) ADJUSTING DRIVE BELT TENSION
11-12-1) Y-Axis Timing Belt
① Push the X frame plate to the driven pulley ([Fig.11-21]) 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 X-Y link bracket and the drive pulley with your finger.
③ Input data for the sound wave tension measurer:
④ Unfasten the tension base screws. Turn the bolts to adjust the tension. Turn clockwise to increase and
counterclockwise to decrease the tension.
[CAUTION]
