The lower fixed blade is made of a special long lasting steel and
does not require frequent replacement.
If necessary, contact your nearest Baby Lock retailer for
replacement of this blade.
The upper moving blade is made of a softer steel material and will
require replacement. A spare blade is provided with the machine
for replacement, if necessary. The spare blade is located in the
thread spool stand accessory compartment.
If for some reason your machine does not cut or perform as it
should, please take your machine to your nearest Baby Lock
retailer. It is possible that the result of poor cutting may indicate
other problems.
To replace the upper moving blade, follow below instructions.
1. For safety reasons, unplug main power cord.
2. Open front cover and cutting blade cover. (fig. A)
Remove presser foot.
3. Turn handwheel so upper moving blade is in its highest
position.

6. Insert screw and hold moving blade in its highest position while
tightening the screw.

moving blade is in its lowest position. Loosen the screw so that
the moving blade can be lowered to 1mm overlap of the top of
the fixed blade. (fig. C)
Tighten the screw.

presser foot.
