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 TIGHT, 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 FRONT COVER. (SEE PAGE 9)
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).
