Replace belt if width is 3 mm (1/8”) less than a new one (refer to TECHNICAL
DATA 09).
2. Check distance between pulleys and/or drive belt deflection.
a.Distance is too small between pulleys or deflection is too high (drive belt engagement

Adjust distance between pulleys and/or drive belt deflection according to specifications
(refer to TECHNICAL DATA 09).
3. Check driven pulley sliding half play.
a.Jammed sliding half.
Replace.
4. Check spring tension of driven pulley sliding half.
