1. There may be the cases where the feed amount of the operation panel and the actual sewing
pitch are different from each other in case of the use in the state other than the standard
delivery or material used. Compensate the pitch in accordance with the sewing product.
2. Be aware that interference between the throat plate and feed dog can occur depending on
the gauge used. Be sure to check the clearance in the gauge to be used. (The clearance
must be 0.5 mm or more.)

When you have changed the stitch length, feed dog height or feed timing, run the sewing
machine at a low speed to make sure that the gauge does not interfere with the changed part.
