6.1 Cleaning the machine
Lint and thread remnants should be removed after every
eight hours of operation using a compressed-air pistol or a brush.
When sewing very fluffy material, the machine should be cleaned
more frequently.
Risk of injury from flying particles.
Turn off the power switch before cleaning.
Flying particles can get in the eyes, causing injury.
Hold the compressed-air pistol so that particles do
not fly toward persons.
Make sure no particles fly into the oil pan.
