Store The Fluid Cartridge; Clean Gun Surface; Clean Air Cap; Lubrication - Graco Fusion A Series Instructions Manual

Store the Fluid Cartridge

If a usable fluid cartridge has been exposed to chemical
and removed from the gun, store the cartridge in a
moisture-free environment.
1. Rinse off any residual chemical with a compatible
solvent.
2. Submerge the cartridge in an acceptable storage
liquid. See Acceptable Cartridge Storage
Liquids, page 39.
To prevent cured material on sealing surfaces and
passages, store cartridges in a moisture-free
environment. Exposure to air can result in cured
material. Cured material can obstruct passages and
damage seals.
Air o-rings on cartridge are not chemically resistant.
Soaking cartridge in solvent will cause o-rings to
swell.

Clean Gun Surface

Keep gun clean with accessory gun cover.
Applying a light coat of lubricant will make cleaning
easier.
Wipe off outside of gun with compatible solvent.
Use N Methyl Pyrrolidone (NMP), Dynaloy
Dynasolve CU-6, SB Versaflex-brand Dzolv
equivalent to soften cured material.

Clean Air Cap

Soak air cap in compatible solvent. Clean holes with #58
(0.042) drill bit.

Lubrication

Liberally lubricate all o-rings, seals, and threads.
Lubricate threads and outside of lock ring (11). See
Lubricant for Gun Rebuild, page 43 to order lubricant.
