Your new Binks Spray Gun is exceptionally rugged in
construction, and is built to stand up under hard,
continuous use. However, like any other fine preci-
sion instrument, its most efficient operation depends
on a knowiedge of its construction, operation, and
maintenance. Properly handled and cared for, it will
produce beautiful, uniform finishing results long after
other spray guns have worn out.
SPRAY GUN |
1. Immerse only the front end of the gun until solvent
just covers the fluid connection.
2. Use a bristie brush and solvent to wash off
accumulated paint.
3. Do not submerge the entire spray gun in solvent
because:
a. the lubricant in the leather packings will dis-
solve and the packings wili dry out.
b. the lubricant at wear surfaces will dissolve
causing harder operation and faster wear.
¢c. residue from dirty solvent may clog the narrow
alr passages in the gun.
4. Wipe down the outside of the gun with solvent
. dampened rag.
5. Lubricate gun daily. Use a light machine oil on:
a. air valve packing.
b. side port control packing.
¢. trigger pivot point.
Coat the fluid control spring with vaseline.
6. Caution: Never use lubricants containing silicone.
This material may cause finish defects.

General Maintenance
PRECAUTIONARY NOTE
All parts on a spray gun should be screwed in hand
tight at first; this will avoid the possibility of cross
threading the parts. If the parts cannot be turned by
hand easily, make sure you have the correct parís,
unscrew, realign, and try again. NEVER use undue
force in mating parts.

. All nozzles and needles are precision made. They
should be handled with care. —
Except as described in 5., do not make any ai-
terations in the gun. To do so could cause
finishing difficulties.
. To clean nozzles, soak them in solvent io dissolve
any dried material, then blow them clean with air.
. Do not probe any of the holes in the nozzles with
metal instruments. If probing is necessary, use
only a tool that is softer than brass.
. Adjust the fluid needle valve so that when gun is
triggered, air-flow occurs before fluid-flow.

POINTERS ON CLEANING
WHEN USED WITH SIPHON CUP
A compatible thinner or solvent should be siphoned
through gun by inserting tube in open container of
that iiquid. Trigger gun repeatedly to flush passage-
way thoroughly and to clean tip of needie.
WHEN USED WITH PRESSURE TANK
Shut off air supply to tank and release pressure on
tank. Open vent and loosen air nozzle. Hold a piece
of cloth over the air nozzle and squeeze trigger. Air
will back up through fluid nozzle, and force fluid out
of hose into tank. Next, put enough thinner into tank
to wash hose and gun thoroughly. Spray thinner
through the gun until it is clean. Attach fluid hose to el mame! a
air line and blow it out thoroughly to remove all |
traces of materials and to dry it.

Binks oil and water extractor is important.
Achieving a fine spray finish without the use of a
good oil and water extractor is virtually impossible.
A Binks Regulator/Extractor serves a double pur-
pose. It eliminates blistering and spotting by keeping
air free of oil and water, and it gives precise air
pressure control at the gun. |

The oi! and water extractor should not be

The temperature of air is greatly increased during
compression. As the air cools down to room temper-
ature, in the air line, on its way to the spray gun, the
moisture contained in it condenses. Thus, for max-

air in the line is likely to be lowest.
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 drained off. Each low point in an air line
acts as a water trap. Such poinis should be fitted with
an easily accessible drain. See diagram above.

HOW TO USE THE CHART
MATERIAL TO BE SPRAYED
Select the type of fluid you want to spray or a fluid
which has the same characteristics as one of those
listed,
METHOD OF FEEDING MATERIAL TO THE GUN
Fluid Nozzle—Consider the speed of application
and the viscosity of the fluid to be sprayed. Referring
to the Fluid Nozzle Orifice Size Chart, those fluid
nozzles which can be changed within an air nozzie
are indicated.
Air Nozzle—Choice is determined by the type of
fluid to be sprayed and the volume of air available for
the gun.
External Mix Nozzles, which are generally used,
accompiish atomization outside the nozzle. Spray
patterns are adjustable from round to fan with all in-
termediate patterns. (Designated by the letter "E™).
Siphon Type External Mix Nozzles—designated by
the letter “S”, will siphon the material from a cup.
Used generally for refinishing and touch-up work
which does not require large quantities of paint.
Pressure Type External Mix Nozzies—designated
by the tetter “P”, require pressure to feed the mate-
rial to the nozzle. A pressure cup, pressure tank or
pump is necessary. Used for production work and
where large quantities of fluid are handied. This type
of nozzle has a greater range of fluid flow and does
not limit the size of the paint container.
Internal Mix Nozzies mix the air and fluid within the
air nozzle. The spray pattern is determined by the
shape of the nozzle and cannot be changed. Internal
mix nozzles require less air and produce slightly less
fog. Pressure equipment must be used with this type
of nozzie. Recommended for maintenance spraying
of heavy materials where a fine finish is not required.
{Designated by the letter 1”).
Volume of Air (CFM required)
The cubic feet per minute (CFM) listed at 30, 50 and
70 PSI is the actual air used by the air nozzle.
increase of pressure subsequently increases vol-
ume of air required by air nozzle, or vice versa.
Assume that a compressor will produce 3-5 CFM
per horsepower.
Note: The greater the air consumption, the faster the fluid may
be applied or the finer a given amount of fluid can be atomized.

SETUP FOR SPRAYING
CONNECTING GUN TO AIR HOSE
Guns should be connected by a suitable length of
5/16" diameter air hose fitted with a connector and a
1/4" NPS(f) nut at gun end.
CONNECTING GUN TO PRESSURE CUPS
See the instructions supplied with the pressure cup.
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 al gun end. 1/4" diameter
nose Is recommended for use with low viscosity
materials. (Fiuid hoses of different composition are
avaliabie for special fiuids.)
OPERATING THE 7 B/C SPRAY GUN
CONTROLLING THE MATERIAL FLOW
When used with a siphon cup an increase in air
pressure will increase the rate of flow. When fed
from a pressure supply an increase in the material
pressure will increase the rate of flow. Correct fluid
nozzle size ensures correct material fiow rate,
CONTROLLING THE FAN SPRAY
The fan spray is controlied by means of the Side
Fort control. Turning this control clockwise until it is
closed will give a round spray; turning it counter-
clockwise will widen the spray into a fan shape. The
fan spray can be turned anywhere through 360° by
positioning the Air Nozzle relative to the gun. To
effect this—loosen retainer ring, position nozzle
then tighten retainer ring.
