To Replace The Gland Seal:
1. Remove the material flow adjustment screw, spring and needle from the back of the gun.
2. Using the opened end of a 7/16" combination wrench, remove the gland nut.
3. Being careful not to damage the threads of the gland nut chamber, remove the gland seal using a hardened
needle or pick.
4. Replace the gland seal and re-install the gland nut.
5. Re-install the needle, spring and material flow adjustment screw.
Tighten the gland nut as much as possible without restricting the free movement of the trigger. If the gun continues to
spray after the trigger is released, the gland nut is too tight. If material leaks out between the gland nut and the
needle directly in front of the trigger, the gland nut is too loose. Adjust accordingly.
