1.
REMOVE THE SCREEN SCREW ASSEMBLY- Using the 3/8” x 5/16” Open End
Wrench, unthread the Screen Screw from the Gun Block. Remove the Screen Screw
retainer, the small ring-like part at the bottom of the screen, before removing the
screen. Remove the Retainer by hand. Now, slide off the Screen. If there are solid
particles attached to the Screen, attempt to soak the screen in Gun Cleaning Solvent.
However, if the screen is especially dirty and clogged, it is better to replace it.
2.
CLEAN THE SCREEN SCREW CAVITY- Inspect the cavity, if any particles are
visible remove them with a combination of the Clean Out Drills mentioned above and
Cleaning Solvent.

3.
REPLACE THE SCREEN SCREW- Using the 3/8” x 5/16” Open End Wrench,
replace the Screen Screw. Make sure the screw is tight to insure the integrity of this
metal to metal seal.
4.
CLEAN THE GUN- Clean the gun after cleaning the Cavities and Screens. See the
Cleaning Procedure section of this manual. In this case, flush the gun with the
module removed. This insures that all particles are expelled from the gun block and
prevents blockage of the module ports.
