Maintenance
Simple sewing machine maintenance operations are described below.
Cleaning the machine
surface
If the surface of the machine is dirty, lightly soak a
cloth in neutral detergent, squeeze it out firmly, and
then wipe the surface of the machine. After cleaning
it once with a wet cloth, wipe it again with a dry
cloth.
Cleaning the race

Sewing performance will suffer if lint and dust

periodically.

the power cord from the electrical outlet.
