Machine Maintenance; Storage; Servicing; Cleaning The Upper Cutter Area - Husqvarna Viking Amber Air S 400 User Manual

MACHINE MAINTENANCE

An overlock requires more frequent maintenance than a conventional sewing machine for two reasons:
• A lot of lint is produced when the cutters are cutting the fabric.
• An overlock runs at a very high speed and needs to be oiled frequently to lubricate the internal working parts.

Storage

When the machine is not in use, be sure to keep it unplugged. Store the machine, so it is not exposed to direct sunlight or humidity.

Servicing

If you have any questions regarding service and/or operation, contact our Customer Care department.

Cleaning the Upper Cutter Area

move any lint.

teeth.
