Knitting machines come in all sizes and shapes, from automated with complex, electronic components to a straightforward, nonmechanical unit. One trait they all have in common is the row of hook style needles that sometimes break or become loose. The process of changing needles may vary slightly based on the set-up of the knitting machine. For precise instructions to replace the needles, you should refer to the user's guide that came with your knitting machine.
Face the machine and look on the right side to locate the retaining bars. The retaining bar is a thin metal rod with a hook on the end. You will see one on both the front and back beds of the machine. Insert a small tool, like a dental pick or flathead screwdriver, into the hook and slide the retaining bar out. Remove the bar on both beds.
Put on a pair of protective eye goggles. Grasp the needle with a wire cutter or needle-nose pliers. You must cut off the latch hook from the needle. Grab the needle behind the hook and squeeze until the latch breaks off.
Pull the needle forward until it stops.
Remove the needle by pulling backwards, out of the needle channel, toward the machine until the needle stops, and then lift upward.
Take the new needle out of the package. Check the needle to ensure the latch is open.
Insert the needle, reversing the steps for removing it. Place the needle at the top of the machine, the hook facing toward you. Push forward and down until the needle is secure.
Slide the retention bars back into place.
