Spray width
adjustment
Spray width adjustment: Turn clock-
wise for round, counterclockwise for fan.
Fluid control screw: Turn clockwise to
decrease flow, counterclockwise to
increase flow.
As width of spray is increased, more
material must be allowed to pass through
the gun to obtain the same coverage on
the increased area.
The first requirement for a good resultant finish is
the proper handling of the gun. The gun should be
held perpendicular to the surface being covered and
moved parallel with it. The stroke should be started
before the trigger is pulled and the trigger should
be released before the stroke is ended. This gives
accurate control of the gun and material.
The distance between gun and surface should be 6
to 12 inches depending on material and atomizing
pressure. The material deposited should always be
even and wet. Lap each stroke over the preceding
stroke to obtain a uniform finish.
It is extremely poor practice to mount the oil and
water extractor on or even near the compressor unit.
The temperature of the air is greatly increased as it
passes through the compressor and this compressed
air must be cooled before the moisture in it will
condense. If the air from the compressor is still
warm when it passes through the oil and water
extractor, moisture will not be effectively removed,
but will remain in suspension. Then, when the air
cools in the hose beyond the extractor, the moisture
will condense into drops of water and cause trouble.
Air lines must be properly drained
Pitch all air lines back towards the compressor so
that condensed moisture will flow back into the air
receiver where it can be removed by opening a
drain. Every low point on an air line acts as a water
trap. Such points should be fitted with an easily
accessible drain. See diagram.

SIPHON SPRAYING
Set atomization pressure at approximate-
ly 50 PSI for lacquer and 60 PSI for
enamel. Test spray. If the spray is too
fine, reduce the air pressure or open fluid
control screw. If the spray is too coarse,
close the fluid control screw. Adjust the
pattern width and repeat adjustment of
spray if necessary.

The spray pattern of
the Binks gun is variable
from round to flat with
all patterns in between.
PRESSURE SPRAYING
After selecting correct size fluid orifice,
set fluid pressure for desired flow. Open
atomization air and test spray. If spray is
too fine, reduce air pressure. If spray is
too coarse, raise air pressure. Adjust pat-
tern width and repeat adjustment of spray.
Keeping fluid control screw in open posi-
tion will reduce fluid needle wear.

NOTE
To reduce overspray and obtain maximum efficiency, always
spray with the lowest possible atomizing air pressure.
In normal operation, the wings on
the nozzle are horizontal as
illustrated here. This provides
a vertical fan shaped pattern which
gives maximum
coverage as the
gun is moved
back and forth
parallel to the
surface being
finished.
Coating should be even
and wet when spraying
