Section 16: Adjusting the Needle Height with Cylinder
Height Gauge QM40131
BabyLock.com
Tools required: Flat screwdriver, #3 x 150 mm in
length, needle-height cylinder tool.
The Cylinder Height Gauge is used to set needle
bar height first, before the hook has been installed
during production of the machine or when the hook
or needle bar have been removed for some reason
during servicing of the machine .
 NOTE: If loop lift is out of adjustment then
needle bar height will also appear to be out of
adjustment when checked by eye.
 NOTE: The hook must be removed to use the
needle height with the cylinder height gauge
so loop lift and needle distance will then need
to be reset .
 NOTE: The Needle Height Cylinder Tool (part
number QM40131 REV.C) fits all Baby lock
machines to date (January 2018).
This adjustment can be completed with the front
frame cover on or off.
Check: When the machine timing is correct the
needle height should look like the first picture on this
page when the hook point reaches the far edge of the
needle. If not, you may wish to set needle bar height
with the cylinder height gauge.
• Remove the needle plate, stop finger, and
hook assembly.
• Turn the handwheel to bring the needle to its
highest position.
• Slide the cylinder height gauge onto the hook shaft
with the flat up. You may have to tap it onto the
shaft a few times to get the air out of the gauge.
