5. USING THE SEWING MACHINE (OPERATION PANEL: BASIC OPERATION) 5-4-2. Setting the length of the hole Set parameter number 02 to the length of the hole that matches the cutter being used. Be sure to change the setting for the length of the hole if the cutter is replaced with a cutter of a different length. The stitch length will be automatically determined by the value for the length of the hole which has been set. Therefore, if the length is not set correctly, problems may occur, such as the bar tacking areas being cut by the cutter. 5-4-3. Buttonhole sewing size A. Length of the hole (Parameter No.02) B.

Parameter number 04 (Cutter X space) does not become larger. If the sewing area is 4.0 mm and parameter number 08 (Zigzag width) is set to 1.8 mm, the cutter X space that can be entered will be limited to 4.0 - (1.8 + 1.8) = 0.4 mm. 4802M Parameter number 29 (Eyelet buttonhole radius) does not become larger or smaller. If the sewing area is 4.0 mm and parameter number 04 (Cutter X space) is set to 0.2 mm and parameter number 08 (Zigzag width) is set to 1.5 mm, the eyelet buttonhole radius that can be entered will be a minimum of (1.5 + 1.5 + 0.2) ÷ 2 = 1.6 mm, and a maximum of 4.0 ÷ 2 = 2.0 mm. 4803M (Continued on next page) 41 HE-800B
