BERNINA B 325

• Universal is listed as 130/705 H in sizes 60-100; other rows specify their own system suffixes and size ranges.

The OEM overview centers on the 130/705 H household-needle family, with system variants and sizes selected by material and use.

• Keep the manual's stated size ranges: 70-90 for jersey/stretch and 90-100 for leather.

Use the listed needle variant for the material: ball-point variants for jersey/stretch and LL or LR cutting-point variants for leather and plastic film.

• Raise the needle, switch power off and lower the presser foot before removal.

Insert the needle fully with the flat side facing the back, then tighten the clamp screw.

• Follow the OEM slot and spring routing shown in the manual.

Insert the bobbin with its thread running clockwise; after routing the thread through the slot and under the spring, the bobbin must still turn clockwise.
