Motor Belt Tension - Janome DE 5024 Servicing Manual

MECHANICAL ADJUSTMENT

MOTOR BELT TENSION

TO CHECK:
1. If the motor belt tension is too tight or too loose, it may cause belt noise.
Also, a too tight belt tension can cause the machine to run slow and will overload the
motor.
Too loose motor belt tension, however, may cause the belt teeth on the motor pulley to
jump.
2. The correct motor belt tension is achieved when the belt pushes in about 7mm - 9mm
under a pressure of about 300 grams.
ADJUSTMENT PROCEDURE:
1. Remove the belt cover (See page 5).
2. Loosen set screws (A) and (B).
3. Move the motor up or down to adjust the deflection to about 7mm - 9mm.
4. Tighten set screws (A) and (B).
5. Attach the belt cover.
