DURKOPP ADLER 550-532 Instruction Manual page 78

Maintenance
Lint and thread remnants should be removed after every 8 hours
of operation using a compressed air gun or a brush. When sewing
very fluffy material, the machine should be cleaned more frequently.
A clean sewing machine provides protection from faults.
Points that need to be cleaned particularly thoroughly:
• Area under the throat plate (1)
• Area around the hook (2)
• Bobbin housing and interior
• Thread cutter
• Area around the needle
