￿-￿-￿. Setting the knife length

Set parameter number 02 to the knife length that matches the cutter being used. (Refer to "5-4-2. Checking the length of knife".)

Be sure to change the knife length setting if the knife is replaced with a knife of a different length.

The stitch length will be automatically determined by the value for the length of the knife which has been set. Therefore, if the knife length is not set correctly, problems may occur, such as the bar tacking stitches being cut by the knife.
