For ordinary sewing, the extension plate will make your work easier.
Carefully place the extension plate on the free arm, levelling the plate with the
free arm, inserting pins on plate into corresponding holes on base of arm.

BASIC INFORMATION
Section 2
needle, thread and fabric chart
fhe needle and thread you choose depends upon the fabric you are stitching.

stiff fabrics.

Use only style 15x1 (European equivalent 705) on this machine. This style or
system is the most commonly used on household sewing machines.
• Always use same type and size of thread in both needle and bobbin.
• Always use a sharp needle. A blunt point can cause skipped stitches or snag
the fabric. Chemical finishes and man-made fibers blunt the needle faster.
• Never use a bent needle.
• If your machine is skipping stitches, replace the needle before looking for
trouble elsewhere.
Special Needles with blue shaft or ballpoint are particularly designed to sew knits and stretch fabrics. Such special needles can prevent sewing from skipping stitches and damaging stretch fabrics. Available in size 9, 11, 14 and 16.
