The LH-3500A Series has made further progress. This is the cutting-edge model 2-needle sewing machine which comes with substantially enhanced mechanisms such as the direct-drive mechanism, semi-dry head, new thread tension control mechanism and improved oiling system.
The location of the oil tank has been changed to the inside of the sewing machine through our re-investigation of the lubricating method. As a result, space is secured under the bed surface to facilitate changeover of the feed method between the "needle feed" and "bottom feed" and changeover of the feed timing (re-placement of the timing belt).
All models of the LH-3500A Series are provided with a semi-dry head to eliminate staining with oil from the frame (the needle bar part).
For the process of sewing light-weight materials or the like, puckering has to be prevented. In this case, the feed method can be changed over to the bottom feed through an easy adjustment and change of the gauge. In comparison with the needle feed, the bottom feed works to prevent puckering and enables sewing with a lower thread tension.
The presser foot can be lifted by a minute amount by adjusting the eccentric pin located in the presser lifter lever section.
When sewing shaggy and elastic fabrics, the load applied to the material is reduced by slightly lifting the presser foot. Materials are handled more easily and are finished without sacrificing the inherent texture of the material.
Our direct-acting thread trimmer mechanism, which spreads thread without fail, has been further improved. The thread trimmer trims the needle thread and bobbin thread without fail even when thick thread is used. In addition, the thread trimmer's bobbin thread retaining force has been increased.
The oil dropped from the hook and its surrounding sections into the under-cover is filtered to remove dirt and dust and is then returned to the oil tank. This method saves the effort of oiling and reduces oil consumption.
The oil dropped from the hook and its surrounding sections into the under-cover is not returned to the oil tank, but only clean oil is supplied to the hook at all times.
★The oiling method can be changed over as desired.

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.
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.

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.
