the hexagon is 11/16 inch from the rear surface of the
barrel packing chamber (refer to Figure 19).

Attaching Barrel to Handle
1. If the barrel retaining nut has been removed, it will have
to be reinstalled before the barrel can be attached to
the handle.
2. Place the retaining nut over the rear of the barrel and
slide it as far forward as possible.
3. Spread the retaining ring and place it onto the barrel.
Starting at one end, lift the retaining ring over the captive
ridge and spiral into place.
4. Place the large hole of the gasket over the needle shaft
and onto the base of the barrel packing chamber.
5. While holding the barrel with the air nozzle pointing
downward, install the needle shaft spring into the spring
retainer. Align the rear end of the barrel assembly with
the matting area of the handle assembly, and the needle
shaft spring with the spring recess in the handle. Slide
the barrel into the handle cavity until it is seated against
the gasket. Ensure the needle shaft spring seats properly
into the handle recess.
6. While holding the barrel in place, screw the retaining
nut onto the handle by hand and then tighten using the
special multi-purpose wrench.
† Torque the retaining ring to 8-10 lbs•ft or after
hand tightening, torque an additional 1/6 to 1/8 turn
using the special multi-purpose wrench.
