    Threading the Bobbin Case. With a few cm of thread hanging loose, place the bobbin in the bobbin case. Slide the thread through the slit in the side of the bobbin case. Run the thread under the tension plate to the notch in the top centre of the bobbin case.
  • Page 11 Adjusting The Stitch. The Strongarm Sewing machine stitches both straight and zig zag, with stitches up to 6mm long and zig zag up to 4 mm wide. To adjust stitch length, lift the stitch length lever up and down. All the way up is 6mm. ½ the way up is 0mm and reverse is all the way down.
  • Page 12 The goal of setting tension is to have the knot made by each stitch lie in the middle of the fabric and be no more visible on one side of the fabric than the other. Tension can be set on the tension dial, as well as on a small screw on the bobbin. It is rare to need to adjust the bobbin tension.
  • Page 13 Adjusting Walking Foot Pressure. Heavier fabric requires more foot pressure. This is applied by turning the knob on the top of the machine above the foot and next to the foot lift lever. Insufficient foot pressure is a common cause of dropped stitches when sewing thick fabric. Foot pressure knob Changing Direction.

  • Page 17: Troubleshooting

    Troubleshooting What do I check when the thread breaks? Make sure the machine is threaded correctly. Check the thread section of this manual to make sure you’re using the right thread. For reliable sewing, use bonded polyester or bonded nylon. Check for defective needle/needles (bent or blunt).
  • Page 18 Why does the thread pull out of the needle when I start to sew? Make sure you have at least 10 cm of thread behind the needle when you start stitching. How can I avoid oil stain on the material? Using a piece of paper towel, clean around the needle and presser bar as often as needed.
  • Page 19 To oil the machine, remove the top and side covers and oil all moving parts especially the metal bearings. Also tip the machine back from its cover and oil the bearings underneath. Be careful tipping the machine back- the Strongarm is heavy and it’s best to have the help of a second person.
  • Page 20 The Strongarm 2000U-33 is a robust machine, but occasionally a broken needle or a thread jam can knock the machine out of timing. Retiming a Strongarm sewing machine is a simple business, and can be performed by machine owners.
  • Page 21 Re-setting the Needle Bar Height If the needle on your Strongarm sewing machine hits a hard object such as a grommet or zip, or if you run into impenetrable fabric such as the reinforced ends of heavy sails, the needle bar may slip to prevent damage to the machine’s gears.
  • Page 22 If the distance is out, then loosen the set screw on the drive collar using a small, high quality screwdriver, set the bar to 16mm, then tighten the set screw firmly. Make sure you don’t rotate the needle bar as you adjust it. distance should be 16-17mm Remember the needle must be in its lowest position when you check the height.
  • Page 23 Left-Right Timing Measurement and Adjustment. If you’ve eliminated every possible cause of dropped stitches, you’ve changed the needle, you’ve made sure the needle is inserted and threaded correctly, that you’re using the correct needle and thread and that the cap spring doesn’t have any burrs, then it’s worth checking the left-right and rotational timing.
  • Page 24 Rotational Timing Measurement and Adjustment. If the machine is still not sewing properly, check the rotational timing. Set the machine to straight stitch, with the needle in the centre position. Place the machine on its back. Remove the bobbin retaining ring. Now turn the balance wheel until the needle is in its absolute lowest position.
