Take a 6cm strip of masking tape and cover each of the interlock PCB contacts in the left and right lid handle.
Use a pencil or whiteboard marker to mark the top of each of the interlock pins.
Close the lid and press down on each handle.
The pins will leave a small mark on the masking tape.
Compare the marks on your masking tape to the conditions below.
If your marks are the same as image above (skewed to the right), apply pressure to your Emblaser2 chassis as shown in the image below.
If your marks are the same as image above (skewed to the left), apply pressure to your Emblaser2 chassis as shown in the image below.
