MAINTENANCE:
Requirements of the A-JU- Automatic Spray Gun have
been reduced to a minimum. The leather packing washers
should be lubricated once a month with a light oil. Old
Packing Washers cause leakage of Air or Fluid. PTFE
Packings are self-lubricating.
CLEANING:
Flush clean solvent through the Fluid passages of the
Spray Gun and Wipe off the outside with clean solvent.
Never leave the entire Spray Gun immersed in solvent.
Dirty Aircaps and Tips should be cleaned by soaking in
solvent and blown clean with air.
NOTE: Never use wire or sharp instruments to clean Fan
Ports as permanent damage to the Air Ports will
result in destroying uniformity of the fan pattern!
MATERIAL & NEEDLE SETTING:
Material should be mixed to consistency recommended by
manufacturer and should always be strained through a lint
free cloth or fine mesh strainer before using.
Item U-3060 Piston Assembly has a needle chuck which
locks the needle in position. The single groove on the
shank of the needle indicates location at which to lock the
piston. Lock piston slightly below mark for use with very
light fluids and slightly above mark (nearer blunt end) for
heavier materials.
