Machine maintenance
Cleaning the machine
Turn off the electrical power
Remove the waste container and open the
looper cover and swivel plate. Disengage the
upper blade (see page 30) and remove the
presser foot and the needle plate.
Use the accessory brush provided to remove
any waste thread from the upper and lower
blades, the differential feed and the looper area.
Cleaning the rubber feet
Clean the rubber feet from time to time with
alcohol. This ensures good stability.
Lubricating the machine
Turn off the electrical power
Move the upper looper into its highest position.
Lubricate the points shown above with recom-
mended sewing machine oil every time you clean
the machine. Use only one or two drops. All other
parts are manufactured from special materials and
do not require any lubrication.
