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 precision instrument, its most
efficient operation depends on a knowl edge
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.

Binks MODEL 7™ SPRAY GUN
GUN HANDLING
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.
NOTE
To reduce overspray and obtain maximum efficiency, always
spray with the lowest possible atomizing air pressure.

SIPHON SPRAYING
Set atomization pressure at approximately 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.

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 pattern width and repeat adjustment of
spray.
Keeping fluid control screw in open position will reduce fluid needle wear.
NOTE
To reduce overspray and obtain
maximum efficiency, always spray
with the lowest possible atomizing
air pressure.

FAULTY PATTERNS AND HOW TO CORRECT THEM
PATTERN CAUSE CORRECTION
Dried material in side-port
“A” restricts passage of air.
Greater flow of air from
cleaner side-port “B” forces
fan pattern in direction of
clogged side.
Dried material around the
outside of the fluid nozzle tip
at position “C” restricts the
passage of atomizing air at
one point through the center
opening of air nozzle and
results in pattern shown.
This pattern can also be caused
by a loose air nozzle.
A split spray or one that is heavy on each
end of a fan pattern and weak in the middle is usually caused by:
(1) Too high an atomization air pressure
(2) Attempting to get too wide a spray pat-
tern with thin material.
(1) Dried out packing around material nee-
dle valve permits air to get into fluid
passageway. This results in spitting.
(2) Dirt between fluid nozzle seat and
body or loosely installed fluid nozzle
will make gun spit.
(3) A loose or defective swivel nut on
siphon cup or material hose can cause
spitting.
Dissolve material in side-ports with thinner,
then blow gun clean. Do not poke into
openings with metal instruments.
Remove air nozzle and wipe off fluid tip
using rag wet with thinner. Tighten air
nozzle.
Reducing air pressure will correct cause (1).
To correct cause (2), open material control
to full position by turning to left. At the
same time, turn spray width adjustment to
right. This will reduce width of spray, but
will correct split spray pattern.
E
F
To correct cause (2), remove fluid nozzle (F),
clean back of nozzle and nozzle seat in gun
body using rag wet with thinner, replace
nozzle and draw up tightly against body.
To correct cause (3), tighten or replace
swivel nut.
To correct cause (1) back
up knurled nut (E), place
two drops of gun lube on
packing, replace nut and
tighten with fingers only.
G
In aggravated cases,
replace packing.

Binks MODEL 7™ SPRAY GUN GENERAL MAINTENANCE
SPRAY GUN
1. Immerse only the
front end of the gun
until solvent just
covers the fluid
connection.
2. Use a bristle 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 dissolve and the
packings will 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 air
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. fluid needle packing.
b. air valve packing.
c. side port control packing.
d. trigger pivot point.
Coat the fluid control spring with vaseline.
Never use lubricants containing silicone since these lubricants
can cause finish defects.
Keep thinner
level below
packing
CAUTION
!
AIR NOZZLE, FLUID NOZZLE, NEEDLE
1. All nozzles and needles are precision made. They should be
handled with care.
2. Do not make any alterations in the gun. To do so could cause
finishing difficulties.
3. To clean nozzles, soak them in solvent to dissolve any dried
material, then blow them clean with air.
4. 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.
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 can not be turned by hand easily, make
sure you have the correct parts, unscrew, realign, and try
again. NEVER use undue force in mating parts.
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 liquid.
Trigger gun repeatedly to flush
passageway thoroughly and to clean
tip of needle.
When local codes prohibit spraying of
thinner or solvent, use a gun washer to
Thinner
➧
clean spray guns.
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 air line and blow it out
thoroughly to remove all traces of
materials and to dry it.

The Clean Air™ filter should not be mounted on or
near the air compressor.
The temperature of air is greatly increased during compression. As the
air cools down to room temperature, in the air line, on its way to the
spray gun, the moisture contained in it condenses. Thus, for maximum
effectiveness, the oil and water extractor should be mounted at some
point in the air supply system where the temperature of the compressed air in the line is likely to be lowest.
AIR PRESSURE
Air pressure at the gun is important.
Atomizing pressure must be set to allow for the drop in air pressure
between the regulator and the spray gun.
Only 44 PSI
25 feet of 1/4” I.D. hose causes a drop of 16 PSI
between the air supply and the gun.
Only 55 PSI
25 feet of 5/16” I.D. hose has a drop of only 5 PSI.
For this reason we recommend the use of 5/16” hose.

Oil and

Drain
25 FEET OR MORE
Air lines must be properly drained.
Pitch all air lines away from the compressor so that condensed moisture
can be drained off. Each low point in an air line acts as a water trap. Such
points should be fitted with an easily accessible drain. See diagram above.
A DeVilbiss Clean Air™ filter is important.
A Clean Air™ filter serves a double purpose. It
eliminates blistering and spotting by keeping air
free from oil and water... and its precision air
regulator makes possible perfect air pressure
control at the gun.
The best spray gun in the world will not operate
efficiently without a good compressor and a
Clean Air™ filter. Model HFRL-508 is recommended.
If you are attempting to get a fine finish without the use of a Clean Air™
filter you will not succeed.
