Measuring depression depth with belt tension tester
Note:
The frequency measurement procedure is the preferred one because it provides more exact results.
1.
Remove protective cover.
2.
Set belt tension tester onto the drive belt in the middle between the belt pulleys (arrowed).
3.
Using pushbutton, press vertically on top side of drive belt exerting even pressure until spring engages
noticeably.
4.
Do not exert any more pressure as displayed value will otherwise be falsified.
5.
Remove tension tester without changing the position of the display arm.
6.
Read off measured value at the intersection of display arm and “KG” scale. Refer to table below for
specified value.
7.
If the measured values deviate from the specified values, adjust drive belt tension (→ Page 108)
8.
Install protective cover.
