SETUP FOR SPRAYING
CONNECTING GUN TO MATERIAL HOSE
Gun should be connected by a suitable length of 3/8"
diameter material hose fitted with a connector with a 3/8"
NPS(f) nut at gun end. 1/4" diameter hose is recommended
for use with low viscosity materials. (Fluid hoses of
different composition are available for special fluids. See
Binks hose catalog for hose selection.)
CONNECTING GUN TO ATOMIZING AIR
Gun should be connected by a suitable length of 5/16"
or 3/8" diameter air hose fitted with a connector and a
1/4" NPS(f) nut at gun end.
CONNECTING GUN TO CYLINDER AIR
Gun should be connected with 3/16" I.D. or 1/8" I.D.
air hose of shortest length possible with 1/4" NPS(f)
connector. Cylinder air must be connected to a 3-way
manual air valve or 3-way solenoid valve to operate
properly.
OPERATING THE MODEL 95A AUTOMATIC SPRAY GUN
CONTROLLING THE MATERIAL FLOW
When fed from a pressure supply, an increase in the
material pressure will increase the rate of flow. Correct
fluid nozzle size insures correct material flow rate. If
necessary, fluid flow can also be adjusted by adjusting
the amount of needle travel. This is done by loosening
lock nut (29) and adjusting control knob (30) until the
correct needle travel is achieved.
ADJUSTING AIR AND FLUID TIMING
A 1/16" gap between the air piston assembly (18) and
needle body (24) should be maintained (see figure 1).
This will create needle motion that will allow adequate
air flow before the fluid starts flowing. The gap may be
adjusted by partially removing the material needle (22),
screwing the needle (22) either in or out of the needle
body (24) and locking it back into the gun while being
sure to check the clearance between the air valve piston
(18) and the needle body (24).
ADJUSTING THE SPRAY PATTERN
The width of the spray pattern is controlled by the side
port control assembly (7). (See page 10). Turning this
control clockwise until it is closed will give a round
spray, turning it counterclockwise will widen the spray
into a fan shape. The fan spray can be turned anywhere
through 360
°
by positioning the air cap assembly (1)
relative to the gun. To effect this, loosen air cap assem-
bly, position nozzle, then, re-tighten air cap assembly.
