MAINTENANCE
Always exercise extreme care when using any solvent or thinner. Never clean gun near fire, flame, or any source of heat or sparks.
Properly dispose of used cleaning materials.
DO NOT soak entire spray gun in solvent or thinner for a long period of time as this will destroy lubricants and possibly make
motion uneven. NEVER use lye or caustic alkaline solution for cleaning. Such solu- tions will attack aluminum alloy parts of gun.
It is important that spray gun be cleaned after daily use. Cleaning is accomplished by spraying appropriate solvent or thinner through system. Wipe exterior of spray gun with solvent soaked cloth or use cleaning brush(s) provided to remove any accumulated material.
Cleaning
(a)Empty material from gravity feed cup and replace with a suitable solvent.
(b)Operate trigger until all material traces have disappeared and gun is thoroughly clean.
(c)Clean air cap with brush.
IMPORTANT: Make certain air cap and fluid nozzle are kept clean at all times. If necessary, remove these two components and soak them in solvent. DO NOT use hard objects to clean clogged holes. The smallest amount of damage may cause irregular spray pattern.
NOTE: If fluid nozzle is to be removed for thorough cleaning, squeeze trigger to prevent dam-
age of fluid needle tip when unscrewing nozzle.
Lubrication
Lubrication procedures must be observed after thoroughly cleaning the gun to ensure effective, high quality performance of spray gun.
1.Lubricate working points with straight mineral oil, or castor oil.
2.Periodically, place a few drops of oil on tapered sections of fluid nozzle to ensure easy operation of air cap. When spraying water base materials, coat fluid nozzle inside and outside with straight mineral oil after each use.
3.Outer diameter of needle sleeve of fluid needle assembly must be lubricated occasionally with straight mineral oil.
Change or Replace nozzle set
When changing nozzle set, make sure the complete nozzle set is exchanged. A set includes an air cap, fluid nozzle, and fluid needle. NOTE: Assemble fluid nozzle before putting in fluid needle.
