guide with the firing poppet shaft, slide the valve body

o-rings on the valve body
(See fiGure 18L),
making sure not to block the gas ports on the valve

assembly has now been fully assembled.
Take the bolt system and insert it into the back of the

key, screw the bolt system into the Etha body.
The bolt system has now been lubricated and
assembled.
