Left needle will not catch in chain









Brother 1034d is not chaining. The upper looper is not passing far enough left to catch the left needle. Makes a "crunchy" sounds some times too.

Needle was inserted completely all the way up?

Make sure you thread in the correct order for your machine (see Threading Your Serger)

First re-thread the machine starting with the upper looper(3), then lower looper(4), then the needles(2,1).

If that doesn't fix it, it may be a matter of loosening the needle tension.

Lastly slowly turn the handwheel and see where the loopers cross.

The upper looper should come in just behind the scarf of the lower looper without any contact on the forward motion. Otherwise Your needlebar height could be off.

Timing a serger is a very precise process and making adjustments could throw it out even further. See TIMING FIX here

Replace needle with a new one.


Turn main power and light switch to the OFF position.


Turn the hand wheel so that the mark on the hand wheel is aligned to the line on the machine.


Loosen the needle set screw with turning the included hexagonal driver to the left direction. And then remove the needles.


Hold the needle with its flat side away from you and insert it up as far as it will go.


NOTE: If the needles have been inserted correctly, the right needle should be set slightly lower than the left one.

Check that the needles are correctly installed. Install needles correctly

Hold the needle with its flat side away from you and insert it up as far as it will go.


Tighten the needle set screw securely with turning the included hexagonal driver toward the right direction.

Thread tension too tight. Adjust the thread tension.


Serging is possible at position '4' for most circumstances.

If the stitch quality is insufficient, select a different tension setting.

Incorrect needle being used. Install correct needle.

This machine uses a standard home sewing machine needle.

The recommended needle is SCHMETZ 130/705H

size#80 or #90
