Care and Maintenance
Simple sewing machine maintenance operations are described below.
Restrictions on oiling
In order to prevent damaging this machine, it must
not be oiled by the user.
This machine was manufactured with the necessary
amount of oil applied to ensure correct operation,
making periodic oiling unnecessary.
If problems occur, such as difficulty turning the
handwheel or an unusual noise, immediately stop
using the machine, and contact your authorized
dealer or the nearest authorized service center.
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.
