  • 1/3 lighter than clutch motors
  • With a flick of the switch you can reverse motor rotation
  • No parts to wear out or adjust

Thanks to the speed control feature, most users find the machine easier to use. Both beginner and advanced sewers find this feature helpful when stitching projects that require high-speed and precise stitching.

Machine Warranty Protection

Besides any applicable warranties provided by the Original Manufacturer, Jacksew offers a standalone 90-day limited warranty on defects in materials and workmanship.

  • This warranty covers all the machine parts and labor but any shipping costs must be covered by the customer

  • Only applies under normal sewing conditions as prescribed for the machine

  • Consumable items are not covered (needles, bobbins, bobbin cases, springs, oil, and belts)

  • This warranty does not cover improper use or abuse under heavy use of machines

  • This warranty does not cover flood, fire, or other acts of nature

If there are any warranty issues that arise, we ask that you contact us immediately and let us know the details. In most cases, we can guide you with getting your machine in good sewing condition via phone, text or video chat.

If you need any parts that need to be replaced, we stock the majority of parts for immediate shipment. Some parts not in stock may have to be ordered from the manufacturer and may take 1 to 2 weeks for arrival.

If there is a critical issue that needs to be addressed and is out of scope of minor adjustments or repairs, we will ask you to send us the machine to our shop so we can have it repaired and have it back to good sewing condition. In most cases, we will only need the machine head shipped to us. Shipping charges - both inbound and outbound - are the responsibility of the customer.

Warranty issues do not arise frequently because of our commitment to assemble, test and verify each machine we ship out to our customers. We will never send you a machine directly from the manufacturer in boxes without knowing that the machine will be ready to operate upon arrival.

DISCLAIMER: DUE TO THE HEAVY WEIGHT AND SHIPPING METHODS USED FOR INDUSTRIAL MACHINES THEY MAY EXPERIENCE MARRING AND SCRATCHES DURING SHIPPING. THIS WILL NOT AFFECT THE OPERATION OF THE MACHINE.

ANY DAMAGE OCCURRING DURING SHIPPING MUST BE CLAIMED TO THE FREIGHT CARRIER IMMEDIATELY. UPON REQUEST, JACKSEW WILL PROVIDE ASSISTANCE IN FILING A CLAIM ON YOUR BEHALF DURING SUCH AN EVENT. PLEASE NOTIFY US WITHIN 5 BUSINESS DAYS.
