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 knowledge
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.
TYPES OF INSTALLATION
SIPHON FEED CUP HOOKUP
Air pressure for atomization is regulated at
extractor. The amount of fluid is adjusted by
fluid control screw on gun, viscosity of paint,
and air pressure (see figure 1).

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 purpose. It eliminates blistering and spotting by keeping air free of oil and water, and it gives precise air
pressure control at the gun.
Binks recommends using Model HFRL-508 Oil and
Water Extractor / Regulator. See your local distributor
for other models.
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.
Coating will
be light at
this point
WRONG
To reduce overspray and obtain maximum efficiency, always
spray with the lowest possible atomizing air pressure.
Coating will
be heavy
at this point
Only 34 PSI at gun inlet
25 feet of 1/4” I.D. hose causes a drop of
26 PSI between the air supply and the gun.
(NOT RECOMMENDED)
48 PSI at gun inlet
25 feet of 5/16” I.D. hose causes a drop of
12 PSI between the air supply and the gun.
For this reason Binks recommends the use
of 5/16” hose.

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.

Spray width
adjustment
Fluid
control
screw
The spray pattern of
the Binks gun is variable
from round to flat with
all patterns in between.
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.
Spray width adjustment: Turn clockwise 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.
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.
FAULTY PATTERNS AND HOW TO CORRECT THEM
PATTERNCAUSECORRECTION
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.
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.
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.
4
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 machine oil
on packing, replace nut
and tighten with fingers

only. In aggravated cases,
replace packing.

Binks MODELS 2001, 2001V AND 2001SS SPRAY GUNS – POINTERS ON CLEANING
When used with a cup, thinner or suitable
solvent should be siphoned through gun
by inserting tube in open container of
that liquid. Move trigger constantly to
thoroughly flush passageway and to clean
tip of needle.
➧
Thinner
CLEANING GUN USED WITH
PRESSURE TANK
Shut off the air supply to the tank and
release the pressure on the tank. Open
vent and loosen air nozzle. Hold a piece
of cloth, wadded in the hand over the air
nozzle and pull the trigger, the air will
back up through the fluid nozzle, and
force the fluid out of the hose into the
tank. Next put enough thinner into the
tank to wash the hose and gun thoroughly and spray this through the gun until it
is clean. Then blow out the fluid hose to
dry it and remove all traces of materials
by attaching it to the air line.
THINNER
Keep thinner level below packing.
It is extremely poor practice to place an
entire gun in thinner. When this is done,
the solvent dissolves the oil in the
leather packing and causes the gun to
spit. It is good practice to place the nozzle and fluid connection in thinner.
Vessel used should be shallow enough to
prevent thinner from reaching packing.
LUBRICATION
Daily oil fluid needle packing, air valve
packing, and trigger bearing screw.
Occasionally coat needle valve spring
with petroleum jelly. OIL ALL WORKING PARTS EVERY DAY.
CONTROLLING THE FAN SPRAY: The
fan spray for an external mix nozzle setup is easily controlled by means of the
side port control (28). Turning this control to the right, or clockwise, until it is
closed will give a round spray; turning it
to the left, or counter-clockwise, will
widen the spray into a fan shape of any
width desired. The direction of the fan
spray, either horizontal or vertical, is
obtained by turning the air nozzle to the
desired position, then tightening the
retainer ring.
CONTROLLING THE FLUID
If a fluid pressure tank is used, the
amount of fluid can be controlled by regulating the pressure on the tank. The
amount of fluid can also be controlled
by means of the fluid control screw (42).
Turning this screw to the right, or clockwise, reduces the amount of fluid; to the
left, or counter-clockwise, increases the
amount of fluid.
FAULTY SPRAY
A faulty spray is caused by improper
cleaning or dried material around the
fluid nozzle tip or in the air nozzle. Soak
these parts in a solvent that will soften
the dried material and remove with a
brush or cloth.
CAUTION
!
Never use metal instruments to clean
the air or fluid nozzles. These parts
are carefully machined and any damage to them will cause a faulty spray.
If either the air nozzle or fluid nozzle is
damaged, the part must be replaced
before a perfect spray can be obtained.
TO REPLACE THE FLUID PACKING:
Remove the fluid control screw (42),
spring (39) and needle. Then remove the
fluid packing nut (12) and take out the
old packings with a small stiff wire.
Replace with new packings (11) oiled
lightly and assemble in reverse order. To
set packing, insert needle, tighten nut
until the needle begins to be too stiff for
the spring to move the needle. Then
loosen nut 1/2 to 3/4 turn.
CORRECTING AIR LEAK
THROUGH GUN
Air leaking through the gun is caused by
the valve stem assembly (6), not seating
properly against the valve body (8).
Remove the valve body (8) and valve
stem assembly (6). Thoroughly clean
parts and inspect for damage. Replace
worn or damaged parts and assemble in
reverse order.
CORRECTING AIR LEAK AROUND
AIR VALVE STEM
Air leaking around the air valve stem (6)
may be caused by worn packings (9) or
damaged air valve stem (6). Remove
trigger (3), packing nut (10) and packings (9). Clean extended portion of air
valve stem (6) and inspect for damage; if
stem is damaged, replace same as above,
insert new packings and assemble in
reverse order.
Keep thinner

Binks MODELS 2001, 2001V AND 2001SS SPRAY GUNS – 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 pack-
ings 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.
CAUTION
!
Never use lubricants contaning silicone. This material may cause finish
defects.
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.
AIR NOZZLE, FLUID NOZZLE,
FLUID 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.
A. 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.
B. 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 nozzle 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, accomplish atomization outside the nozzle. Spray patterns are adjustable from round to fan
with all intermediate patterns.
(Designated by the letter “E”).
NOZZLE SELECTION
(See chart on page 7)
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 Nozzles,
designated by the letter “P”, require
pressure to feed the material to the
nozzle. A pressure cup, pressure tank
or pump is necessary. Used for production work and where large quantities of fluid are handled. This type of
nozzle has a greater range of fluid
flow and does not limit the size of
the paint container.
—Internal Mix Nozzles 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 nozzle.
Recommended for maintenance
spraying of heavy materials where a
fine finish is not required.
(Designated by the letter “I”).
C. 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 volume 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.
All air nozzles shown in combination with these (+) fluid nozzles can also be used in combination with any other fluid nozzle marked (+)
*See text Section B, page 6, for type code. ★All standard needles listed are stainless steel.
■ Replaces 54-3347 Side Port Control when using internal mix nozzles.
✔ Also available: Heavy Duty Spring 54-1372, not furnished. Please order separately.
