Jack A4E-Q
Heavy Duty, Computerized, Direct Drive, Drop Feed, Single Needle Lockstitch Machine

Price: $1,125.00

(You can always remove it later.)

Featuring an all new chassis design that provides increased rigidity, reducing vibrations at higher speeds. The A4E also features a variable stitch function, giving you some decorative stitches within the control panel with the push of a button. The improved thread trimmer reduces the thread tail left after sewing. The all new control panel gives you all the same automatic functions such as adjusting sewing speed, thread trimming and back-tacking, but now allows you to control stitch length via push of a button and eliminates the external adjustment knob.


Work Smarter

The Jack A4 was designed to improve operator efficiency and reduce fatigue. Built on the same all steel chassis as the rest of the Jack lineup and driven by the coaxial direct drive AC servo motor, the A4 is full of features not found on competitively priced machines.


Simplified Control

The Jack A4 control panel is simple and intuitive. From the control panel the user can adjust sewing speed, set needle position (up/down), turn on/off auto thread trimmer function, set automatic foot lifter operation, turn on/off electronic thread tension, set bartacking function or even program segmented sewing allowing the operator to repeat simple sewing tasks like sewing labels or pockets.


User Friendly

The Jack A4 comes standard with integrated adjustable LED lighting, a half/full stitch button and a reverse button that can be used instead of the reverse lever. The presser foot can be raised by hand or automatically by foot pedal. On top of the machine is an integrated bobbin winder, allowing you to wind bobbins while continuously sewing.


Direct Drive

No complicated motors or belts to deal with; the Jack A4 comes equipped with an integrated AC servo motor. The servo motor is mated to the machine head by a proprietary coaxial shaft that reduces vibration and noise; this allows the user to perform consistent seams at any speed.


Automatic Foot Lifter

The Jack A4 features an automatic foot lifter with a variety of settings. The foot lifter can be set to automatically lift with the optical fabric sensor or simply by slightly depressing the foot pedal backwards. There are several settings that can be adjusted by the push of a button depending on the needs of the sewing operation.


Automatic Thread Trimmer

The Jack A4 features an automatic thread trimmer function. The thread trimmer function can be tuned on or off depending on the sewing operation with just a simple push of a button. Once turned on, fully depress the foot pedal backwards to cut the thread.


Modern Design

The Jack Sewing Machine Co. LTD, lineup of machines have all undergone design updates improving not only functionality but aesthetics. In addition to the redesigned machine head, the heavy duty table and stand have all undergone updates as well. Each machine ships as a complete set.
