Preparations

Pack away after sewing

1. Switch the main switch off.

2. Unplug the cord from the wall socket and then

from the machine.

3. Unplug the foot control cord from the machine.

Wind the cord around the foot control for easy

storage.

4. Place all accessories in the accessory tray. Slide

the tray on to the machine around the free arm.

5. Place the foot control in the space above the

free arm.

6. Put on the hard cover.

Free arm

To use the free arm, slide off the accessory tray.

When attached, a hook keeps the accessory tray

locked to the machine. Remove the tray by sliding

it to the left.

Thread cutter

To use the thread cutter, pull the thread from back

to front as shown (A).

Spool pins

Your machine has two spool pins, a main spool

pin and an auxiliary spool pin. The spool pins

are designed for all types of thread. The main

spool pin is adjustable and can be used both in a

horizontal position (the thread reels off the spool)

and a vertical position (the thread spool rotates).

Use the horizontal position for normal threads and

the vertical position for large spools or specialty

threads.

Horizontal position

Place a spool cap and the thread spool on the spool

pin. Make sure that the thread reels over the top

and slide on a second spool cap.

Use a spool cap slightly larger than the thread

spool. For narrow thread spools, use a smaller

spool cap in front of the spool. For large thread

spools, use a larger spool cap in front of the spool.

The at side of the spool cap should be pressed

rmly against the spool. There should be no space

between the spool cap and the thread spool.

Needle threader

The needle threader allows you to thread the

needle automatically. The needle must be in the up

position to use the built-in needle threader. We also

recommend lowering the presser foot.

1. Use the handle to pull the needle threader all

thewaydown.Thethreaderhook(G)swivels

through the needle eye.

2. Placethethreadfromthebackoverthehook

(H)andunderthethreadhook(G).

3. Let the needle threader gently swing back. The

hook pulls the thread through the needle eye

and forms a loop behind the needle. Pull the

thread loop out behind the needle.

Note: The needle threader is designed to be used for size

70-120 needles. You cannot use the needle threader for

size 60 needles or smaller, a wing needle, twin needle or

triple needle. There are also some optional accessories

that require manual threading of the needle.

Threading for twin needle

Replace the sewing needle with a twin needle.

Make sure that the presser foot is raised and the

needle is in the up position.

Note: Change the needle often. Always use a straight

needle with a sharp point (G).

A damaged needle (H) can cause skipped stitches,

breakage or snapping of the thread. A damaged needle

can also damage the stitch plate.

Do not use asymmetrical twin needles (I), since it may

damage your sewing machine.
