mECHANICAL ADJUSTmENT
mOTOR BELT TENSION
TO CHECk:
1. If the motor belt tension is too tight or too loose, it can cause a belt noise: if the tension is too toight, it can
cause the machine to run slowly and the motor to overload; if the tension is too loose; it can cause the belt
teeth on the motor pulley to jump.
2. The correct motor belt tension is when the deflection of motor belt is about 7mm (0.28”) - 9mm (0.36”).
(When pushing the motor belt by finger with a 300 gram load.)
ADJUSTmENT PROCEDURE:
1. Remove the rear cover. (See page 6)
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).
