How do you thread an imperial machine?

To thread an imperial machine, first, ensure that the machine is powered off and the needle is in its highest position. Begin by placing the spool of thread on the spool pin and guiding the thread through the tension discs, ensuring it sits properly. Next, thread the take-up lever and follow the threading path down to the needle, making sure to thread it from front to back. Finally, pull a few inches of thread through the needle and check that everything is secure before turning the machine on.
