Checking the Needle

The sewing needle must always be straight and sharp for smooth
sewing.

To Check the Needle Correctly:
To check the needle, place the flat side of the needle on a flat
surface. Check the needle from the top and the sides. Throw away
any bent needles.

1 Parallel space
2 Level surface (bobbin cover, glass, etc.)

*

Place a level surface under the needle.

Replacing the Needle

CAUTION

Turn the main power switch to OFF before changing the
needle. If the main power is left on and Start/Stop button
is pressed or foot controller is stepped on, the machine
will start and injury may result.

Use only sewing machine needles for home use. Other
needles may bend or break and cause injury.

Never sew with a bent needle. A bent needle will easily
break and cause injury.

1. Remove the power supply plug from the outlet.

2. Raise the needle bar to its highest position.

3. Lower the presser foot.

4. Remove the needle by loosening the needle clamp screw.

1 Presser foot lever

CAUTION
Do not loosen or tighten the needle clamp screw with a strong
force, otherwise it may be damaged.

5. With the flat side of the needle facing the back, insert the new

needle all the way to the top of the needle stopper (viewing
window) in the needle clamp. Use a screwdriver to securely
tighten the needle clamp screw.

2 Needle stopper
3 Hole for setting needle
4 Flat side of needle

CAUTION

Be sure to push in the needle until it touches the stopper,
and securely tighten the needle clamp screw with a screw-
driver. If the needle is not completely inserted or the needle
clamp screw is loose, the needle may break or the machine
may be damaged.
