1. Set the parallel angle of the fan and the motor pulley as shown in the table and figure 1 below.
2. Set the tension of the per one belt when the flexion load is within the range as shown in the figure 1 and table
2 below at the proper flexion. (A = 0.016
×
C mm)
3. Adjust the suitable tension after the belt sit properly across the pulley (after more 24-28 hours working).
When the new belt is used, adjust the suitable tension about the 1.3 times of the maximum value of the flexion
load.
4. Readjust the belt every 2,000 hours after the first adjustment.
Exchange the belt when the belt’s surroundings length has expanded by 2% including the first expansion of
the belt. (about 1%) (about 8,000 hours converted working time)
