BINKS MODEL 21 & 21V SERIES AUTOMATIC SPRAY GUN
HOOK-UP
1. Air pressure of 35-50 PSI minimum required for
cylinder 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. A DeVilbiss centrifugal air filter 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. 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 (16) 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
accomplished by loosening locknut (17) and turning
screw (16) 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 (29). These parts should be kept soft and pliable
at all times. SSL-10 gun lube is recommended for this.
!
Never submerge the gun in solvent. Solvent will wash the
oil off the lubricated parts and cause subsequent
malfunctioning of the gun.
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 flush through the material hose and spray gun until
clean. Blow air through the fluid hose to eliminate
residual solvent. Always follow EPA and NFPA
regulations when spraying or cleaning spray equipment.
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.
!
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.
