Holding the collar of the micrometer (11) turn the dial counter-clockwise until the number 5 can be seen
on the midsection.

Using soft tip pliers grab the midsection section of the micrometer and turn clockwise to snug it onto the
upper air body (10).

Use a 1/16” Allen key to assemble the set screw (16) into the upper air body (1
0) securing the micrometer
(11) in place.
