NOTE
NOTE
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 nee-
dle 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.

7. Check the spacing between the back of the spring
retainer and the handle. It should be about 1/8-inch.
If not, check for one or more of the following:
• Gasket has been left out
• Loose retaining nut
• Loose fluid nozzle
• Improper adjustment of the trigger adjustment nut
and spring retainer
8. Secure the trigger with the two (2) shoulder screws.
†
The needle shaft travel MUST be checked. The
air valve stem must be engaged and moved back
slightly before the trigger engages the trigger ad-
justment nut. If this does not occur then the trigger
adjustment nut and/or the trigger set screw must be
adjusted. The 11/16-inch dimension is only a start-
ing place for trigger adjustment and can be altered to
obtain proper triggering sequence.
