14. REINSTALL THE VALVE LINER- Push in the brown Valve Liner as far as it will

go. Some resistance is normal, as there is interference between the O-rings on the
Valve Liner and the inside diameter of the hole. Push it in until two or three internal
threads in the hole are visible. These threads allow engagement of the Valve
Retainer Nut which when screwed in, will align the Valve Liner and Spool to their
proper depth.

15. REINSTALL THE 1/16” PLUG- Using the 5/32” Hex Key thread the 1/16” Pipe

plug back in place. Apply a small amount of pipe thread sealant to the threads prior
to insertion. This helps seal the threads and prevent air leaks.

NOTE:

If removing the Pipe Plug(s) or

Air Hose was not necessary,

skip Steps 15 and 16.

16. REINSTALL THE 1/8” PIPE PLUG- Using the 3/16“ Hex Key reinstall the 1/8”

Pipe Plug in the gun.

17. REINSTALL THE VALVE SPOOL- Insert the Valve Spool, with the Valve Spool

Spring in place into the Valve Liner. Screw in the Valve Retainer Nut. Be careful
not to over tighten it, just tighten until it is “snug”.

18. REASSEMBLE THE TRIGGER LEVER- Reinstall the Trigger Lever using the

Screw and Lock Nut. Tighten using the 6” Adjustable Wrench and the 6”Pliers.

NOTE:

Guns configured with the air

supply connected to the rear

of the Gun, as opposed to the

base of the Gun Handle,

require reinstallation of the Air

Hose and Pipe Nipple using a

6” Adjustable Wrench.

19. REINSTALL THE SIDE BLOCKS ON THE GUN BLOCK- Using the 5/32”

Hex Key secure the A and R Side Blocks to the Gun Block with the two socket head
cap screws. Make sure to sufficiently tighten the screws equally to prevent leakage.

20. PERFORM START UP PROCEDURE- See Daily Start Up Procedure on Page 12.
