Oiling/Lubrication
Trimming
The trimming button is used to trim the top and bobbin thread if you need to move to another needle
or if you want to stop your machine during embroidery and remove your hoop.
Trimming is also useful when rethreading a needle because it automatically inserts the thread from
the needle’s eye into the presser foot. This helps speed up the threading process.
You can press the trimming button during embroidery mode or setup mode as long as the machine
isn’t running. Press the key in order to trim the top or bobbin thread and then press “Yes.” The machine
will now trim on the selected needle.
Some embroidery machine issues can be linked to the lack of routine care, therefore proper maintenance
is essential to prolong the life and functionality of your machine. It is necessary to oil your machine
to ensure it operates smoothly. Lubricate your machine with sewing machine oil, which can be found
in most sewing and embroidery supply stores, and white lithium grease, which can be found in many
hardware stores. Before using any other product, please ask a certied technician to conrm the
product is safe for your machine.
EVERY FOUR HOURS:
1. Remove the bobbin case and apply two to three drops of sewing machine oil on the race of the rotary
hook, where the two sections of the hook meet. See Figure 97.
2. Remove the bobbin case and clean the hook assembly area with a soft brush, air compressor with a
moisture lter or approved canned compressed gas product, such as Dust Off. See Figure 98.
