Usb Port; Free Arm/Removable Accessory Tray; Presser Foot Lever; Thread Knife - Singer SE9150 Instruction Manual

USB Port

Your machine has one USB port for connecting USB devices
such as a memory stick. USB plugs can only be inserted one
way – do not force them into the ports! To remove, carefully
pull the USB device.
Note: You can only access your stored files on the USB in the
embroidery mode.
Note: Your machine can read USB devices that are compatible
with both type 2.0 and 3.0 and has the format FAT32.

Free Arm/Removable Accessory Tray

Store presser feet, bobbins, needles and other accessories in the
accessory tray so that they are easily accessible.
Keep the accessory tray on the machine to provide a larger, flat
work surface.
Use the free arm to facilitate sewing trouser legs and sleeve
hems. To use the free arm, slide off the accessory tray. When
attached, a hook keeps the accessory tray securely attached to
the machine. Remove the tray by sliding it to the left.

Presser Foot Lever

The presser foot lever is located at the right side of the sewing
machine head. The lever is used to raise and lower the presser
foot.
By raising the presser foot lever and then pressing it farther up-
wards, the lift height of the presser foot is increased to an extra
height allowing you to place thick fabric layers under the foot.

Thread Knife

To use the thread knife, pull the thread from back to front as
illustrated. Doing this will leave the thread ends long enough
so that the needle doesn't become unthreaded when you start to
sew again.

Thread Sensor

If the needle thread breaks or bobbin thread is running low, the
machine stops and a pop-up appears on the screen.
If needle thread breaks: Remove the thread completely,
re-thread the machine and touch OK in the pop-up.
