Clean Breather Plug
Remove and clean breather plug with compatible sol-
vent. See materials of construction info in Technical
Data, page 55. The breather plug is part of the solenoid
manifold assembly (30). See FIG. 19. Use N-Methylpyr-
rolidone (NMP), Dynasolve CU-6, Dzolv, or an equiva-
lent to soften cured material. Applying a light coat of
lubricant will make future cleaning easier. Torque
breather plug to 30-40 in-lb (3.89-4.82 N•m).
Clean Fluid Manifold

vent and brush whenever removed from gun. See

exposed, to seal out moisture. See FIG.20.
