REMOVE VALVE RETAINER NUT- Using the 6” Adjustable Wrench, remove
the Valve Retainer Nut. This is the hex shaped nut that surrounds the brass Valve
Spool and holds it in place.
6.
REMOVE THE VALVE SPOOL- Using the 6” Pliers take hold of the end of the
Valve Spool and remove it from the gun. A spring will come out with it. Make sure
not to loose this spring as it belongs in the hole at the end of the Spool.
7.
REPLACE THE O-RINGS- If necessary, replace the O-Rings on the Valve Spool
after applying a thin coat of Lubriplate Grease to them.
8.
REMOVE THE VALVE LINER- Attempt to pull the Valve Liner out of the gun
handle through the trigger hole. If successful, proceed to Step 11. If unsuccessful,
proceed to Step 9.
NOTE:
Follow Steps 9 through 16 to
replace the O-rings on the
Valve Liner. If they do not
need replacing go to Step 18.
9.
REMOVE THE REAR INTERNAL 1/16” PIPE PLUG- Deeper in the hole from
which the 1/8” Pipe Plug (or Air Hose) was removed, locate the 1/16” Pipe Plug.
Remove this Plug using the 5/32” Hex Key.
10. REMOVE THE SPRING SEAT- Looking into the hole from which both Plugs
were removed the brass surface of the Spring Seat can be seen. Using the Pin Punch
of ¼” diameter or less, and the Ball Peen Hammer, gently tap the Spring Seat until
both it and the Valve Liner are pushed out the opposite end of the hole.
11. REMOVE & REPLACE THE O-RINGS- Remove and replace the four O-Rings
on the Valve Liner. Apply a light coat of Lubriplate Grease to the O-Rings.
12. CLEAN THE VALVE HOLE AND REMOVE ANY DEBRIS- After insuring
hole is free of any debris apply a thin coat of Lubriplate to the inside of the hole.
13. REINSTALL THE SPRING SEAT- Slide the brass Spring Seat back into the Gun
Handle Air Valve hole tapered end first until it bottoms out in the hole.
