Instructions to Thread a White Speedylock Serger

By James Andrews ; Updated September 15, 2017
Sergers sew fabric faster than standard sewing machines.

Also known as overlockers, sergers sew fabric and clothes faster than normal sewing machines while at the same time generating perfect seams. Ideal for industrial production, sergers like the White 1600 Speedylock can be threaded quickly with the help of a chart located inside the front cover. Threading must be carried out in the following sequence: upper looper, lower looper, right needle, left needle. You should use tweezers to help you complete this task.

Front Cover

Open the free arm and front cover so that you can see the useful threading chart inside. Slowly turn the hand wheel toward you until the upper and lower loopers arrive at the easiest threading position.

Looper Eyes

Pass the thread through the two looper eyes and along the correct threading guide path. Ensure the thread sits between the two disks located inside the serger's numbered tension dials.

Presser Foot

Pull out the thread end around 4 inches (10 cm) from the looper eyes. Raise the presser foot and position the threads under the foot before lowering it back into place.

Hand Wheel

Rotate the serger's hand wheel toward you so that the right and left needles are fully raised.


Pass the right and left needle threads and ensure the thread sits between the two disks inside the tension dials. Guide the thread through the eyes of both needles.

Presser Foot

Pull around 4 inches of spare thread (10 cm) from the eyes of the needles. Raise the presser foot and place the threads under the foot before lowering the foot back into place.
