Light bulbs are available at your authorized PFAFF® dealer. Change the light bulbs as described below. 3W Turn off the main switch. 1 Place the light bulb remover with the deep 5W hole, marked OUT, around the bulb. Do not turn the bulb, just pull it out to remove it. 2 When inserting a new light bulb place the remover with the shallow hole, marked IN, around the new bulb. Insert the new bulb by pushing it up. Cleaning the machine To keep your sewing machine operating well, clean it often. No lubrication (oiling) is needed. Wipe the exterior surface of your machine with a soft cloth to remove any dust or lint built up. Wipe the graphic display with a clean, soft and damp cloth.

Place the screwdriver under the stitch plate as shown on the picture, and gently turn the screwdriver to pop off the stitch plate.
