CAUSE
Paint droplets too large.
Paint droplets drying too fast to prop-
erly flow out of gun.
Cold weather spraying.
~~~ ~ ~~
Moisture condensation is trapped
in
the lacquer when spraying
in
hot, hu-
mid conditions.
Silicone contamination from lubri-
cants, grease, polish, or waxes on the
surface being sprayed.
Applying too much paint per pass for
the
drying
conditions.
Sprayed surface drying before solven
gas can be released.
SOLUTION
Maintain proper spraying distance:
see page
12.
Keep the turbine air filters clean to
allow
full
air flow. See page
13.
Do
not use an air hose that is to0
long to provide sufficient atomiza-
tion pressure.
reduce the fluid or use a smaller
air cap.
If droplets are still too large,
Keep
the
object being sprayed out of
direct sunlight. When spraying in
warmer temperatures, use a slower
evaporating solvent or a retarder.
Keep the fluid and the object being
sprayed as close
to
room temperature
as possible. When sprayed on a cold
surface, most paints will become too
thick to flow properly.
Allow the turbine to warm up a few
minutes before spraying.
Store the lacquer
off
concrete
floors, at room temperature.
Apply lighter coats and ailow for
proper drying time.
Use a slower evaporating solvent
or retarder.
Do
not spray
in
windy conditions.
Clean all parts with a cleaning solvent:
wipe with. Replace rags as needed. If
use a solvent rag and a clean rag to
