Oiling And Care; Cleaning A Thread Jam - Strongarm Walking Foot Sewing machine User Manual

Oiling and Care

Your Strongarm 2000-U33 comes pre-oiled and ready to sew. The Strongarm is a precision
tool, and the metal bearings will be "tight" straight from the factory. As the machine wears in,
you'll notice your Strongarm becomes quieter and the flywheel easier to turn by hand.
Oil your machine regularly for long service life. Oil once a week if used heavily. Use only
sewing machine oil, and never use WD-40 or other lubricants.
To oil the machine, remove the top and side covers and oil all moving parts especially the
metal bearings. Also tip the machine back from its cover and oil the bearings underneath. Be
careful tipping the machine back- the Strongarm is heavy and it's best to have the help of a
second person.

Cleaning a Thread Jam

To clean a thread jam, you'll need to disassemble the bobbin system. First, turn the balance
wheel until the needle is at its highest point. Tilt the machine back and remove the bobbin case
and bobbin. Turn the two small black levers (A and B) down and remove the bobbin retaining
ring (C). Grab the hook (D) by its axle and remove.
Then you can remove any snagged thread using tweezers or your fingers. Use a small brush
or compressed air to clean away any lint or dirt.
