MECHANICAL ADJUSTMENT
MOTOR BELT TENSION
TO CHECK:
1. IF THE MOTOR BELT TENSION IS TOO TIGHT OR TOO LOOSE, IT MAY CAUSE THE BELT TO MAKE
NOISE.
A TOO TIGHT MOTOR BELT TENSION CAN CAUSE THE MACHINE TO RUN SLOWLY AND WILL
OVERLOAD THE MOTOR; A TOO LOOSE MOTOR BELT TENSION, MAY CAUSE THE BELT TEETH
TO JUMP OVER THE PULLEY.
2. THE CORRECT MOTOR BELT TENSION IS ACHIEVED WHEN THE BELT IS PUSHED IN ABOUT 7 MM
(0.28") - 9 MM (0.36") UNDER A PRESSURE OF ABOUT 300 GRAMS.
ADJUSTMENT PROCEDURE:
1. REMOVE THE BELT COVER (SEE PAGE 9).
2. LOOSEN THE SETSCREWS (A) AND (B).
3. MOVE THE MOTOR UP OR DOWN TO ADJUST THE DEFLECTION TO ABOUT 7 MM (0.28") - 9MM
(0.36").
4. TIGHTEN THE SETSCREWS (A) AND (B).
