AUTOMATIC AIR SPRAY GUN WITH STAINLESS STEEL FLUID INLET
MODEL 95A AND 95AV SPRAY GUN
The Binks Model 95A Automatic Spray Gun is a conventional style air spray gun. It incorporates all stainless steel
fluid inlet, fluid nozzle, and fluid needle for spraying a
wide variety of conventional and waterborne coatings.
Model 95AV incorporates tungsten carbite fluid nozzles
used in ceramic and abrasive coating applications. It is also
pneumatically activated for application with reciprocating,
rotary, spindle machines, and in stationary gun set-ups.
STANDARD SET-UPS AVAILABLE (SEE PG. 9).
OPTIONAL SET-UPS PLEASE ORDER SEPARATELY
(SEE PGS. 8 & 9).
Exceptionally rugged in construction, the Binks Model 95A
and 95AV guns are built to stand up under hard, continuous
use. However, like any other fine precision instrument,
their most efficient operation depends on a knowledge of
their construction, operation, and maintenance.
Properly handled and cared for, these guns will produce
beautiful, uniform finishing results long after other spray
guns have worn out.

GENERAL NOTES
1. Have at least 55-60 P.S.I. air pressure for cylinder’s
operating air. (Maximum 90 PSIG)
2. To reduce overspray and obtain maximum efficiency,
always spray with lowest possible fluid/air pressure
that produces an acceptable spray pattern.
3. The air line from gun to 3-way valve should be as
short as possible for rapid operation.
4. All air used in the gun should be dirt and moisture
free. (This is accomplished by using an oil and water
extractor).
5. Shut off all fluid and air lines to gun if gun is to stand
idle for any length of time. (This is to prevent “build
up” or accumulation of minute leaks in the system
and turning on the gun).

TO CHANGE FROM COMBINED FAN AND ATOMIZING AIR
TO SEPARATE FAN AND ATOMIZING AIR
1. Unscrew end cap (28) and remove material needle
(22) and attached parts (23, 24, 25) (see assembly
drawing page 10).
2. Remove piston assembly (18) by injecting low
pressure air into cylinder air port (A).
!
WARNING
Use of excessive pressure will cause piston to exit gun
body at high velocity, possibly resulting in personal injury
or damage to spray gun components. When removing the
piston, aim back of gun in a safe direction and do not use
excessive air pressure.

SETUP FOR SPRAYING
CONNECTING GUN TO MATERIAL HOSE
un should be connected by a suitable length of 3/8"
G
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"
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),
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.

manual air valve or 3-way solenoid valve to operate
properly.
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 assembly, position nozzle, then, re-tighten air cap assembly.

MAINTENANCE
LUBRICATION
onthly: Remove piston assembly (18) and lubricate the
M
air cylinder chamber and needle valve spring with a
coating of Gunners Mate (47). Also, lubricate side port
control assembly (7) with oil.
CAUTION
!
Never use lubricants containing silicone since these
lubricants can cause finish defects. Binks Gunners Mate
(47) is recommended.
REMOVAL OF PISTON
To remove the piston, first unscrew the end cap (28),
remove 2 springs (26 & 27) and pull out the material
needle (22) and attached parts (23, 24, & 25). Remove
the piston by applying a few pounds of air pressure to
the cylinder air inlet. This air pressure will cause the
piston to pop out.
!
WARNING
Excessive air pressure applied to the piston during
removal may cause the piston to exit at a high velocity,
resulting in personal injury. When removing the piston,
aim back of gun in a safe direction and do not use
excessive pressure.
TO REPLACE NEEDLE SEAL AND GLAND
ADAPTER IN FLUID INLET
Remove end cap (28), springs (26 & 27) and assemble
material needle (22) and attached parts (23, 24, & 25).
roceed to the front of the gun and remove air cap
P
assembly (1) and fluid nozzle (2). Then, using wrench
(44), unscrew head insert (4) and remove fluid inlet
(33 or 34). Unscrew packing nut (39) and remove spring
(38) and seal backup (37). Using a No. 10 x 1-1/4"
coarse thread wood screw (Binks part no. 20-6536) or
small sheet metal screw, remove the needle seal (36)
and gland adapter (35). Replace gland adapter (35) and
needle seal (36). Reinsert seal backup (37), spring (38)
and screw on packing nut (39) a couple of turns so it fits
loosely by hand. Reassemble fluid inlet (34) to gun body
(5) with head insert (4). Tighten head insert using
wrench (44). Reassemble fluid nozzle (2) and air cap
assembly (1). Reinsert material needle (22) and attached
parts (23, 24 & 25), springs (26 & 27) and screw on end
cap (28). Finally, tighten packing nut (39) until it bottoms
out on fluid inlet (34).
In certain states it is now against the law to spray solvents containing Volatile Organic Compounds (VOCs)
into the atmosphere when cleaning a spray gun.
In order to comply with these new air quality laws Binks
recommends one of the following two methods to clean
your spray finishing equipment:
1. Spray solvent through the gun into a closed system.
An enclosed unit, or spray gun cleaning station, condenses solvent vapors back into liquid form which
prevents escape of VOCs into the atmosphere.
2. Place spray gun in a washer type container. This system must totally enclose the spray gun, cups, nozzles,
and other parts during washing, rinsing, and draining
FAULTY SPRAY
A faulty spray may be caused by improper cleaning,
dried materials around the fluid nozzle tip or in the air
cap. Soak these parts in thinners 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 faulty spray.
If either the air cap assembly (1) or fluid nozzle (2) are
damaged, these parts must be replaced before perfect
spray can be obtained.
CLEANING
cycles. This type of unit must be able to flush solvent
through the gun without releasing any VOC vapors
into the atmosphere. Additionally, open containers for
storage or disposal of solvent, or solvent-containing
cloth or paper, used for surface preparation and cleanup may not be used. Containers shall be non-absorbent.
To clean the gun, flush the fluid lines with solvent and
blow air through the air lines to make sure all the air
passages are dry.
Never completely submerge the gun in solvent as this will
dissolve the lubricating oil and dry out the seals.
TROUBLESHOOTING
INTERMITTENT SPRAY
If the spray flutters, it is caused by one of the following
faults:
1. Insufficient material available. Check supply and
replenish if necessary.
2. Loose fluid nozzle (2). Tighten, but without using
undue force.
3. Leakage at gland adapter (35) and needle seal (36).
Tighten packing nut (39) if loose, and replace gland
adapter and needle seal if necessary.
4. Fluid connection insufficiently tight or dirt on cone
faces of connection. Correct as necessary.
5. Leaking cylinder air and/or inadequate pressure.
