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 solutions 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
• Empty material from gravity feed cup and replace with a suitable solvent.
• Operate trigger until all material traces have disappeared and gun is thoroughly
clean.
• Remove Air Cap and clean with the provided cleaning brush.
IMPORTANT:
Make certain air cap and fluid nozzle are kept clean at all times.
If necessary, remove these two components (internal fluid nozzle can be removed
using the provided wrench) 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 damage of fluid needle tip when
unscrewing nozzle.
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.
