24. Replacing needles
This machine is equipped with type 2022 needles (for domestic and over-
locking machines)
NOTICE!
Risk of damage!
Bent or blunt needles can cause damage to the machine and material.
Switch off the machine.
Replace the defective needle.
Turn the handwheel (38) towards you until the needles (19) are in the
highest position.
Loosen the clamp screws from the needles using the supplied small
screwdriver from the accessory compartment and remove the needles:
upper screw for the left needle and lower screw for the right needle.
Push the new needles into the needle holder with the flat side facing to
the back. When doing so, ensure that they are pushed in as far as possi-
ble.
Tighten the needle clamp screw again.
Once the needles have been inserted correctly, the left needle is posi-
tioned slightly higher than the right. If the needles have not been inserted
correctly, occasional stitches will be missed.
