Care of Sewing Machine

How to Clean and Oil the Sewing Machine
Cleaning and oiling your sewing machine is basic maintenance that bits of lint, thread,

dust and even fabric can get stuck in your machine. These make work harder and can even
jam your sewing machine. Clean your machine to fix these help the machine to last longer
and perform more smoothly. If you sew regularly, problems and use sewing machine oil to
help the moving parts function smoothly. You should clean and oil your machine after
finishing any large project as well as any time you suspect it is having a problem.

INSTRUCTIONS:
1. Prepare the needed tools and supplies in cleaning the
sewing machine. Remove the needle if there is any.
This will prevent the cleaner from pricking fingers during
the cleaning process.

Face Plate (presser bar, needle bar, thread take
up lever, lifter).

• Unscrew face plate and keep it in the drawer while
cleaning.
6

• Brush dust away then put a little amount of oil while rotating the balance wheel
to inner parts can be accessed.

• Put back the Face Plate in place.

UPPER TENSION ( DISC SPRING AND DIAL )

• Remove outer bolt , tension dial , discs and disc
spring.

• Lay each part in your front table following its
disassembling for easier assembling.

• Brush dust and wipe with absorbent cloth with oil.
• Assemble by following the laid parts in your table.

LOWER MECHANISM ( ROTARY OSCILLATING HOOK )

• Remove bobbin case.
• Fasten sides of oscillating hook.
• Remove dust with lint brush.
• Put a little amount of machine oil on moving parts.
• Return spare parts in place.

OTHER MINOR PARTS

• Remove entangled threads between head and balance wheel.
• Brush accumulated dust in the treadle joints connecting the band wheel.
• Clean gummy dust on the band wheel.
• After all parts were dusted, lubricate all joints and oil slots with good quality oil.
• Wipe off all surplus oil then put a piece of absorbent cloth under the presser foot for

dripping oil.

Note : When the machine has thoroughly cleaned and oiled, run it slowly for several
minutes to allow the oil to work on its moving parts. Place a scrap of fabric under the presser
foot and lower the needle to absorb excess oil.
