When the needle bar stroke is altered, it is absolutely necessary to readjust the
needle height! With a 36 mm needle bar stroke, the maximum speed must be
limited to 3800 spm.
● Via the hand wheel, turn crank 1 until the screws 2 can be accessed from the side
opening of the housing.
● Turn eccentric 3 (screws 2) as far as possible toward "+" (= large needle bar stroke) or
toward "-" (= small needle bar stroke).
● Adjust needle height (see chapter 11.05.02 Preadjusting the needle height and/or
chapter 11.05.14 Needle rise, hook-to-needle clearance, needle height and bobbin
case position finger).
11.05.21 Modifying the needle bar stroke
The needle bar stroke is preset in the factory according to requirement. The
needle bar stroke can be modified later if specific operating conditions make it
necessary to do so.
