5.13 Maintenance
This section describes simple maintenance work that needs to be carried
out on a regular basis. The maintenance work can be carried out by the
operating personnel.
Advanced maintenance work should only be carried out by qualified tech-
nicians. Further maintenance work is described in the  Service Manual.
5.13.1 Cleaning
Lint and thread remnants must be removed at least every 8 operating
hours using a compressed-air pistol or a brush. When sewing very fluffy
material, the machine should be cleaned more frequently.
ATTENTION
Malfunctions due to machine contamination.
Lint and thread remnants can impair the operation of the machine.
Clean the machine at regular intervals as described in the manual.
WARNING
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 enter into the oil pan
