Maintenance
WARNING :
Please refer to the safety instructions.
Changing the upper knife
The upper knife (moving knife) is made from special hardened ma-
terial.
Replace the upper knife only when the knife blade tip is damaged.
For a replacement, contact your local dealer.
Changing the lower knife
Main switch off “O”. Disconnect machine from electri-
city supply.
Turn handwheel towards you until needles are fully raised. Match
the matching up marks on hand wheel and side cover. Raise the
upper knife.
Loosen the setscrew on the lower knife retaining plate. Remove the
lower knife.
Fit the replacement knife (from accessory bag) in the groove so that
the sharp edge is in line with the stitch plate. Re-tighten the set-
screw.
Cleaning and lubricating
Main switch off “O”. Disconnect machine from electricity
supply.
During sewing, dust and fluff collect in and on the machine. This
should be removed regularly. Your overlock machine requires very
little lubrication. Now and then, lubricate only the points illustrated.
Please refer to safety instructions.
