If the Pop Valve Assembly still does not operate properly, the Pop Valve Assembly must be checked as follows:
1. Place the End Plug Pin hole in the Tube over a pin held in a vise; then using snap lock pliers, remove the knurled Barrel Retainer 300-46.
This permits removal of the Barrel and Pop Valve Assembly.
2. Lock the Barrel and Pop Valve Assembly in a vise on the flat: remove Valve Cap 300-5 using snap lock pliers.
3. Remove Valve Spring 300-8, Valve 300-6 with Quad Ring 300-37 and Valve Sleeve 300-7. Replace any defective parts. Pop Valve and
Quad Ring should work easily in Valve Sleeve 300-7 and Valve Sleeve should not bind in Valve Cap 300-5.
To reassemble valve, place Valve Sleeve and Pop Valve in the Valve Cap. Hold the Pop Valve firmly and blow into the three holes in the
Valve Cap to insure that the air does not bypass.
Reassemble the gun as follows:
1. Degrease the threads on the Valve Body 300-4 and the Valve Cap 300-5, apply Loctite Grade C to the threads on the Valve Body and
screw the Valve Cap tightly to the Valve Body. (Note: Valve Sleeve 300-7, Pop Valve 300-6 with Quad Ring 300-37 and Valve Spring 300-
8 must be assembled to the Valve Cap prior to this assembly).
2. Degrease threads on Tube 300-3 and Barrel Retainer 300-46. Apply Loctite Grade C to the threads on the Tube. Assemble Barrel and
Valve Assembly to the Tube, screw on Barrel Retainer but do not tighten. Place End Plug Pin hole in Tube over pin held in vise with the
solid side of the Tube up. Line up BB hole in the Valve Body with the pin hole in the top of the Tube and tighten the knurled Barrel
Retainer with snap lock pliers. (Note: It may be necessary to use an open end wrench to maintain alignment of holes when tightening the
Barrel Retainer}.
3. Reassemble Hammer Sleeve Assembly 300-47 to Tube. (Use care in this assembly to avoid damaging the Teflon Ring).
4. Assemble Plunger Spring 300-23 and End Plug 300-22. Press against a hard surface and insert End Plug Pin 300-24 so that it extends an
equal distance from either side of the Tube.
5. Assemble Tube and Barrel Assembly to L. H. Frame, insert BB Retaining Ball 105-39 and Ball Spring 350-17.
6. Reassemble Sear Spring 140-27.
7. Assemble R. H. Frame 300-2 and four Frame Screws 300-54.
