For multiple gun installation, a fluid manifold may be used.
Fluid adjustments are made using the fluid control screw on
each gun. However, when precise fluid control is necessary,
a fluid regulator for each gun must be used.
1. Provide 50-60 PSI (minimum) air pressure for gun cylinder
operation.
2. Air line from gun to 3-way valve should be as short as
possible for maximum speed of operation.
3. Recommended hose sizes are 3/8" for fluid and 1/4" for air.

WARNING
!
In this part sheet, the words WARNING, CAUTION and NOTE are used to emphasize important safety information as follows:
CAUTION
Hazards or unsafe practices which could
result in minor personal injury, product
or property damage.
!
WARNING
Hazards or unsafe practices which could
result in severe personal injury, death
or substantial property damage.
!
NOTE
Important installation, operation or
maintenance information.
Read the following warnings before using this equipment.
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO
THE OPERATOR OF THE EQUIPMENT.
FOR FURTHER SAFETY INFORMATION REGARDING BINKS AND DEVILBISS EQUIPMENT,
SEE THE GENERAL EQUIPMENT SAFETY BOOKLET (77-5300).
READ THE MANUAL
Before operating finishing equipment, read and
understand all safety, operation and maintenance
information provided in the operation manual.
AUTOMATIC EQUIPMENT
Automatic equipment may start suddenly without
warning.
INSPECT THE EQUIPMENT DAILY
Inspect the equipment for worn or broken parts
on a daily basis. Do not operate the equipment
if you are uncertain about its condition.
NEVER MODIFY THE EQUIPMENT
Do not modify the equipment unless the
manufacturer provides written approval.
KNOW WHERE AND HOW TO SHUT OFF THE
EQUIPMENT IN CASE OF AN EMERGENCY
PRESSURE RELIEF PROCEDURE
Always follow the pressure relief procedure in the
equipment instruction manual.
NOISE HAZARD
You may be injured by loud noise. Hearing
protection may be required when using this
equipment.
STATIC CHARGE
Fluid may develop a static charge that must be
dissipated through proper grounding of the
equipment, objects to be sprayed and all other
electrically conductive objects in the dispensing
area. Improper grounding or sparks can cause a
hazardous condition and result in fire, explosion
or electric shock and other serious injury.
FIRE AND EXPLOSION HAZARD
Never use 1,1,1-trichloroethane, methylene
chloride, other halogenated hydrocarbon solvents
or fluids containing such solvents in equipment
with aluminum wetted parts. Such use could
result in a serious chemical reaction, with the
possibility of explosion. Consult your fluid
suppliers to ensure that the fluids being used are
compatible with aluminum parts.
WEAR SAFETY GLASSES
Failure to wear safety glasses with side shields
could result in serious eye injury or blindness.
DE-ENERGIZE, DISCONNECT AND LOCK OUT ALL
POWER SOURCES DURING MAINTENANCE
Failure to De-energize, disconnect and lock out
all power supplies before performing equipment
maintenance could cause serious injury or death.
OPERATOR TRAINING
All personnel must be trained before operating
finishing equipment.
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equip ment to
rupture, malfunction, or start unexpectedly and
result in serious injury.
KEEP EQUIPMENT GUARDS IN PLACE
Do not operate the equipment if the safety
devices have been removed.
PROJECTILE HAZARD
You may be injured by venting liquids or gases
that are released under pressure, or flying debris.
PINCH POINT HAZARD
Moving parts can crush and cut. Pinch points are
basically any areas where there are moving parts.

Binks Model 21 (BRASS BODY) AUTOMATIC SPRAY GUN
INTERNAL MIX HEAVY MATERIAL NOZZLES (OPTIONAL)
HOOK-UP
1. Air pressure of 50-60 PSI minimum required for cylin-
der operation.
2. For rapid operation, the air line between three-way
valve and the cylinder operating air connection should
be as short as possible.
3. All air supplied to the gun should be dirt and moisture-
free. An oil and water extractor mounted in the air
supply line is recommended.
4. If the gun is to stand idle for any length of time, shut
off. This will prevent small leaks throughout the
system from turning on the gun.
FAN SPRAY ADJUSTMENTS
The fan spray is easily controlled by means of the side
port control stem, (22). Turning this control to the right,
or clockwise, will give a round spray pattern. Turning it
to the left, or counter-clockwise, will widen the spray into
a fan shape of any desired width. Orientation of the fan
spray either horizontally or vertically (or to any position
in between) is obtained by loosening the retainer ring,
rotating the air nozzle to the desired position, and then
tightening the retainer ring.
FLUID FLOW ADJUSTMENTS
For best results, the fluid control screw (18) should be set
at the open position and the flow of the fluid controlled
by regulating the fluid pressure in the pressure tank. If
the conditions under which the gun is being used require
the fluid to be controlled at the gun, it may be accom-
plished by loosening locknut (19) and turning screw (18)
to the right (clockwise) to decrease the flow of fluid or
the left (counter-clockwise) to increase the flow of fluid.
LUBRICATION
The points that require lubrication on this gun are the
plunger (7), the air valve packing (11), and the fluid
packing (36). These parts should be kept soft and pliable
at all times. A light machine oil is recommended for this
lubrication.
CLEANING
Shut off the air supply to the tank and release its pressure.
Hold a piece of wadded cloth over the gun nozzle and
turn on the air to the cylinder. The air will back up
through the fluid nozzle and force fluid out of the hose
and into the tank.
Replace the paint in the pressure tank with clean solvent
and spray the solvent through the gun until it is clean.
Dry out the residual solvent in the fluid hose by blowing
air through it.
FAULTY SPRAY
Faulty spray is caused by dry coating material residue
around the fluid nozzle tip or inside the air nozzle. Soak
these parts in a solvent that will soften the dried residue
until it can be removed with a brush or a cloth.

CAUTION
Never submerge the gun in solvent. Solvent will wash the
oil off the lubricated parts and cause subsequent malfunc-
tioning of the gun.
!
CAUTION
Never use metal probes to clean the air or fluid nozzles
because scratches and burns on their precision machined
surfaces can cause faulty spray. If either the air or fluid
nozzle is damaged so as to give faulty spray, it must be
replaced.
