Regulating belt of tension

Refer to the following figure, loose 2 bolts, and move the electric motor to adjust belt tension. These
two bolts are used for precision adjustment.

Belt tension is measured by belt tension indicator


Calculate the deflection, deflection (L) = A/64.
Notes: L=A/64

Measure the belt deflection force, the force should be between the values shown in the
following lists.

The belt which is too tight or too loose may generate noise and be harmful to the unit.
