Janome Four-DLB Serger Review

The Janome Four-DLB serger is a well-built, efficient machine for a basic compact serger.

This serger may lack some of the bells and whistles seen on other Janome machines, but it makes neat, even stitches, and isn’t too difficult to thread.

The looper cover’s color-coded guide and instructive owner’s handbook are both straightforward.


  • The Janome Four-DLB is very simple to thread and operates for a manual machine.
  • This feature makes thread tension adjustments a breeze.
  • The serger makes very little noise or vibration when used, which is unusual for a lightweight serger.


  • Because of its small weight, this model struggles with heavier materials or several layers.
  • The workspace to the right of the needles is quite tiny, which might make control difficult.

Stitch Options

The Four-DLB has 3-thread rolling and thin hemstitches, a flatlock stitch, and a beautiful picot edging stitch in addition to normal and wide 3- and 4-thread overlock stitches.

The stitch length may be changed between 1 and 4 mm.


  • Speed: 1,300 stitches per minute
  • Threads: 3-4
  • Color-Coded: Yes
  • Light: Bulb
  • Weight: 14.3 lbs.
  • Dimensions: 15.5 inches by 14.5 inches by 12.75 inches

Built-in Dual-Purpose Needle Plate

The Four-unique DLB’s needle plate lets you rapidly convert from a straight stitch to a rolled hem stitch by just turning a switch on the machine’s side.

When you change the setting to the ‘R’ position, you’ll be able to produce excellent rolling or thin hem stitches almost immediately.

Adjustable Differential Feed

Adjustable Differential Feed  You have total control over how easily the finest or heaviest materials slide under the needles by selecting the appropriate feed dog setting.

This function also aids in the creation of wonderfully uniform gathers and flawless flat stitches. The feed ratio may be adjusted between 0.5 and 2.25 millimeters.

Foot Pressure Adjustable Presser

This fantastic feature combines with the differential feed to offer you complete control over any cloth you’re working with.

You may guarantee that all of the stitches are tight, smooth, and even by changing the pressure, the presser foot gives to the cloth. Even the most delicate textiles will be within your control.

Retractable Upper Knife

When working on a job that doesn’t require fabric cutting, retracting the upper cutting blade comes in useful.

Turn the release knob toward you while pushing it to the right to disengage the upper knife, then lock it into the ‘down’ position.


The Janome Four-DLB comes with a 25-year mechanical parts guarantee, a 5-year electrical component warranty, and a 1-year labor warranty.

The Verdict

The Janome Four-DLB is a very simple beginner serger that performs exactly what it says on the box. While significantly more expensive than sergers in the same class, it stitches at a peak pace of 1,300 per minute.

It generates crisp, uniform stitches every time and cuts the cloth neatly. The tension knobs and the differential feed and presser foot pressure are simple to adjust.

If you’re searching for a decent novice serger, keep in mind that you’ll be investing in Janome quality by purchasing this machine.
