DISPOSE OF BACK DOOR STAY ASSEMBLY
Secure the back door stay assembly horizontally in a vise with the piston-rod pulled out.
Wear safety glasses. Use a metal saw to slowly cut a groove between A and B shown in the illustration to release the gas.
Note
Although the gas inside the back door stay assembly is colorless, odorless, and harmless, metal debris may scatter. Therefore, cover the back door stay assembly with a piece of cloth or other material.
