  • Do not use the sewing machine if there is visible or audible damage.
  • While in operation, always keep your eye on the sewing area and do not touch any moving parts such as the thread uptake, handwheel, v belt, bobbin winder, motor, etc.
  • Keep hands away from the needle when you turn on the machine and while it is in operation
  • Turn off the machine when leaving the sewing table
  • Turn off the machine when replacing the needle or presser foot
  • Turn off the machine when threading or cleaning the machine.
  • Do not attempt to sew over pins! If you are using pins, they must be removed before they reach the presser foot.


  • Make sure the oil pan is filled with oil.
  • Insert a bobbin.
  • The grove on the needle should be facing the inside of the machine.
  • Thread the machine. The needle should be threaded from left to right (or outside to inside).
  • Adjust the stitch length and presser foot pressure if necessary.
  • Adjust the height of the knee lift if necessary


Once you’ve inserted a bobbin, the machine is threaded and you’ve adjusted the settings for your project, turn on the machine.

Use the knee lift to raise the presser foot, then insert your fabric under it.

Gently press on the foot pedal. The machine goes much faster than a home sewing machine. Depending on your project, you may want to reverse a couple stitches at the beginning and end to secure the stitches.


  • Pay attention to what you are doing as you sew.
  • Don’t let pins go under the presser foot; this is especially dangerous given the speed of the machine.
  • Make sure that the stitches are forming and that you haven’t run out of bobbin thread or that your needle came unthreaded.
  • Keep an eye out for needles breaking.
  • If the machine makes a significant amount of noise or any weird noises, stop using it and report it in the slack channel.

Shutdown & Cleanup

  • Power off the machine.
  • Put the cover on the machine.
  • Please discard all thread and any other scraps.
  • If there are thread and cuttings on the floor vacuum them up.
  • Empty the trash when it gets full.




The Kingmax has needles, bobbins, a bobbin case, and screwdrivers. The extra needles, bobbins and screwdrivers are stored in the drawer of the sewing table. The bobbin case should be left inserted in the machine under the table.


Industrial sewing machines can handle everything from lightweight fabrics to heavy fabrics, multiple layers of fabric, and thick materials like leather or vinyl. Make sure to use industrial needles and industrial thread.
