carried out by the operating personnel. Additional maintenance
work may only be performed by specially trained and qualified
technicians. The additional maintenance work is described in the

6.1 Cleaning the machine
Lint and thread remnants must be removed after every 8 hours of
operation, using a compressed-air pistol or a brush. When sewing
very fluffy materials the machine must be cleaned more often.
WARNING
Risk of injury from flying particles.
Turn off the power switch before cleaning.
Swirled up dirt particles can get into the eyes and
cause injury.
Hold the compressed-air pistol so that particles do
not fly toward persons.
Make sure no particles fly into the oil pan.
ATTENTION
Malfunctions can occur due to a dirty machine.
Lint and thread remnants can impair the operation of the
machine.
Clean the machine at regular intervals according to the
instructions in the manual.
