MODEL BL9
MECHANICAL ADJUSTMENT
MOTOR BELT TENSION
To check:
1.Too tight or too loose motor belt tension may create belt noise and also too tight motor belt
tension can cause the machine to run slow and will overload the motor.
Too loose motor belt tension may cause jumping of the belt teeth on the motor pulley.
2.The correct motor belt tension is that the deflection of motor belt is about 7mm (0.28") - 9mm
(0.36") when pushing the motor belt by finger at about 300 grams load.
Adjustment procedure:
1.
Remove the belt cover (See page 4).
2.
Loosen the screws (A) and (B).
3.
Move the motor up or down to adjust the deflection about 7mm (0.28") -9mm (0.36").
4.
Tighten the screws (A) and (B).
