IMPORTANT
The most efficient atomization air pressure is the lowest
air pressure that will properly atomize the paint. This will
minimize the overspray, deposit more paint on the surface
and eliminate paint wastage.
If a faster coverage is necessary, first increase fluid pres-
sure and then adjust atomization air pressure. If a slower
coverage is more desirable, first reduce the fluid pressure
and then adjust atomization air pressure. Always attempt
to maintain the lowest pressures for maximum efficiency.
For ease of removing cup cover and to prevent leakage,
always thoroughly grease the threads on cup.
CLEANING
1. Open air release valve on pressure cup cover.
2. Reduce pressure in cup until gauge reads zero, (turn
knob counter-clockwise).
3. Loosen cup cover and set fluid tube on angle in cup.
4. Loosen air nozzle two turns, place cloth over nozzle
and pull the trigger to force paint into cup.
5. Remove cover and clean cup and cover thoroughly.
6. With approximately 1/4 to 1/2 cup of clean solvent, attach
cover and set fluid pressure at approximately 10 PSI.
7. Close air adjusting valve at spray gun.
8. Trigger gun and allow solvent to flow into a container
until it flows clear.
9. Remove solvent, then clean air nozzle. If any dirt
appears in orifice, clean with tooth pick; wire will
damage nozzle. Blow nozzle and cup dry. Replace
nozzle and cover loosely.
Internal Mix Air Nozzle Application
OPERATION
The internal mix air nozzle accomplishes atomization by
mixing the air and fluid within the air nozzle.
1. Close air adjusting valve by turning clockwise.
2. Set air pressure at oil and water extractor (transformer)
to approximately 45 PSI.
3. Open air adjusting valve and allow air to enter the gun.
4. Set fluid pressure at 20 lbs. and adjust higher or lower
until desired atomization is effected. Air pressure
should be alternately adjusted.
CAUTION
If the cup is accidentally tipped over or held at too great an
angle, fluid will load up the underside of cup cover, and leak
into regulator. In the event this happens, clean immediately!
!
NOTE
The steps are the same as with the external mix nozzles,
except the air and fluid pressure settings are different.
NOTE
Never allow solvent to remain in cup; solvent vapors tend
to reduce service life of gasket. Separate storage of cup
and cover recommended.
