fresh wax strengthens the thread
and causes it to stick in place. The
stronger the thread, the less breakage
in the operation of the machine. wax
will also lubricate your thread for
smoother operation. wax is especially
recommended for threads made of
natural fibers.
Liquid thread Wax
• Mix your wax thoroughly to ensure good results.
• Before sewing, clean your machine, oil rollers and
gummed up mechanisms. pull out and cut off both upper
and lower threads that have hardened.
• Only use enough liquid wax in your machine wax pot to
cover your thread (approximately half full) or enough for a
days use. Anything in excess may thicken before it can be
used.

removing the Bobbin
• Release the cover latch and open bobbin door
• Remove the bobbin cover (UL-291)
• Remove the bobbin (UL-290)
threading the Bobbin
• Insure that the bobbin spring (UL-292) has been placed in the
shuttle with the prongs of the spring bent facing the bobbin (to
the operator's right).
• Put the bobbin into the shuttle. The thread should flow off
the bobbin easily, from the top and the bobbin in a clockwise
rotation.
• Place the bobbin cover (UL-291) over the bobbin and close
the bobbin door. Make sure that a length of thread is pulled
out of the bobbin door between the spring and the door latch.
Winding the Bobbin
• For natural threads, leave the label up on the spool of thread
• Put the thread through the extended wire of the bobbin winder and then through
the small wire hook. come over the top of the thread disk twice for better
tension adjustment.
• Slide the threader (UL-531), through the wax pot and grab the thread and pull it
through the wax pot. The nuts on the wax pot will turn and adjust how much wax
to be applied on the thread.
• Fill the bobbin with equal tension (DO NOT wind the bobbin either very tight or
very loose, but with firm, even tension). Bobbins that are wound, either, very
tight or very loose, or in the same bobbin, tight and loose, will cause the stitch
length to vary all over the place; and this is the cause of the problem.
• Start off by winding the thread over the top of the bobbin a couple of times by
hand. Again the thread, coming out of the wax pot, should feed over the bobbin.
The bobbin will spin in a counter clockwise motion. Do not overfill the bobbin.
leave a small open area so that the thread is not unraveling off of the bobbin.

• Do not neglect to renew wax frequently, or your thread
may become unreliable and break. The fresher your wax,
the better your machine will work.
• It is best to wind your bobbins as you use them, as a fresh
bobbin will do better work than an old one.
• Be careful to have strippers in wax pot tight enough to
clean off all surplus wax
• Adjust Strippers as necessary and clean out the Wax Pot
occasionally
LAx Wax - Water Based Wax
• If LAX Wax Thread Lubricator is used, it is possible to thin
or clean the lube with water.
hot Wax
• If hot wax is desired the machine must be requested with
special ordered heated wax pots
thread Lubricant
• When sewing with synthetic threads, Lily White Oil or
Silicone lubricant can be used.
