Use the Hook Gage supplied with the machine to set the proper length on the Hook. The Hook should extend the distance of the gage from the tip of the Hook to the Hook Carrier.
This gage is a starting point; different thread or fabric may make it necessary for you to increase or decrease the length of the Hook. The Hook should be level in the Carrier.
The Latch should not be point up or down when open. You can adjust the Latch to be down if the Hook is striking the Needle.
