Where to Find the Best Value
The SiRUBA HSO-747D doesn’t include any of the bells and whistles found on more expensive sergers, although its basic manual features are up to par with others in the same class. In addition to handling a variety of fabrics with ease, it includes an adjustable differential feed, an adjustable presser foot and a free arm option. On the down side, there’s no DVD to accompany the poorly-written instruction manual, but there are several online tutorials you can access for help in threading the machine. Also, the durability of this serger is questionable due to being constructed of low-quality plastic.
In addition to producing 3- and 4-thread narrow and wide overlock stitches, the SiRUBA HSO-747D also offers users rolled and narrow hem stitch options. The standard stitch length can be adjusted to between 1 mm and 5 mm, the narrow stitch length is from 1 mm to 2 mm, and the narrow or picot edging stitch varies between 3 mm and 4 mm. The rolled hem stitch length is also adjustable between 1 mm and 2 mm.
Using either needle, the stitch width on the 3-thread narrow and wide overlock stitch is 4 mm.
Speed: 1,300 stitches per minute
Weight: 15 lbs.
Dimensions: 11.6 inches by 11 inches by 11.6 inches
Adjustable Differential Feed
The differential feed controls the movement of fabric through the stitching process while preventing puckers and pulls in knit and lightweight fabrics. The feed dogs also give you better control over heavy or multiple layers of fabric. The feed can be adjusted between 0.7 mm and 2 mm, which also allows you to create perfectly even gathers.
Unlike several other entry-level sergers, this This model includes a free arm option which allows you better access when putting a professional finish on cuffs, sleeves, and other projects that might be difficult to complete. Removing the support bed instantly converts the machine to a free arm.
Adjustable Presser Foot
For producing the best sewing quality on all fabric types and thicknesses, the presser foot is easily adjusted by loosening or tightening it with the small screwdriver included with purchase. The lift height of the presser foot is 4 mm, which makes it easy to work with thicker fabrics or multiple layers.
Adjustable Thread Tension
The thread tension dials for both needles and the upper and lower loopers are conveniently located on the front of the 747D. Each dial can be easily adjusted to find the perfect tension setting for the type and thickness of the thread and fabric you’re working on.
Non-retractable Thread Cutter
The cutting width can be adjusted by turning a knob to the proper setting between 5.5 mm and 6.5mm from the left needle and between 3.5 mm and 4.5 mm from the right needle. The upper blade is not retractable.
This SiRUBA model includes only a 1-year limited warranty.
SiRUBA included a powerful motor that’s more than capable of handling the top speed of 1,300 stitches per minute. Unlike many other sergers, the freearm on this machine is short and compact, which might mean a tight working area for some users. However, it does produce clean, even stitches on a wide range of fabric types and thicknesses. As with many entry-level sergers, mastering the manual threading process is half the battle. But the affordability might just take the edge off some of that frustration.
