MECHANICAL ADJUSTMENT
MOTOR BELT TENSION
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 7 mm (0.28”) - 9 mm (0.36”) WHEN PUSHING THE MOTOR BELT BY FINGER AT
ABOUT 300 g LOAD.
TO ADJUST
1. REMOVE THE BELT COVER.
2. LOOSEN THE SCREWS (A) AND (B).
3. MOVE THE MOTOR UP OR DOWN TO ADJUST THE DEFELECTION ABOUT 7 mm (0.28”) -
9 mm (0.36”).
4. TIGTEN THE SCREWS (A) AND (B).
