Maintaining the machine
An overlock machine requires more maintenance than a regular sewing
machine. There are two main reasons for this:
1. Trimming the fabric edges produces a lot more fabric dust.
2. And overlock machine runs at very high speeds and therefore requires
regular oiling to ensure the moving parts remain moving.
Cleaning the machine
ATTENTION! Always unplug
from the socket before cleaning
the machine.
Regularly remove dust and lint
from the looper and knife area.
Use a dry brush to do so.
Note: a lint brush is sold separately.
Oiling the machine
ATTENTION! Always unplug
from the socket before oiling the
machine.
Regularly oil the lubricating points
indicated in the illustration.
Note: only use sewing machine
oil. Using other oils can damage
the machine.
Replacing the
lower knife
ATTENTION! Always unplug
from the socket before replacing
the lower knife.
The lower knife should be replaced
as soon as it becomes dull.
The lower knife can be replaced
with the help of these instructions.
If you do have difficulties, please
contacted your authorised
SINGER retailer.
Verify the power plug is unplugged.
Open the looper cover and bring
the upper knife (1) to the rest
position.
Loosen the retaining screw (2)
and remove the lower knife (3).
Insert a new lower knife into the
notch of the lower blade holder.
Tighten the retaining screw (2).
Return the upper knife (1) into the
operating position.
