To access the light bulb, use the button-hole foot to lift up the insert on the arm cover. Remove the cover. Hold the edge guide slightly tilted and push it into the opening in the head of the sewing machine. Press down on the lamp housing to hold it still. Push up on the bulb and turn it counter-clockwise. Once the bulb is loose, pull it down and out of the lamp housing. To replace the bulb, continue to hold the lamp housing. Push the new bulb into the housing and rotate it clockwise. Release the lamp housing and then use the button-hole foot to replace the cover.
