13. OPTIONAL PARTS



CAUTION

Installation of optional parts should only be carried

out by a qualified technician.



Turn off the power switch and disconnect the power

cord before installing any optional parts, otherwise

the machine will operate if the treadle is pressed by

mistake, which could result in injury.

If any safety devices have been removed, be

absolutely sure to re-install them to their original

positions and check that they operate correctly

before using the machine.

Never touch the knife on the face plate when

opening the thread takeup guard cover, otherwise

injury may result.

When removing the needle plate, auxiliary needle

plate and knife unit, use a screwdriver that matches

the size of the screw heads.

If a screwdriver with a size that does not match is

used, it may damage the screw heads and cause

personal injury or damage to the sewing articles.
