note
To reduce overspray and obtain maximum efficiency always spray with the lowest possible atomizing air pressure.
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.

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.
OPERATINg THE Sv50 gRAvITy FEEd SPRAy guN
CONTROllINg THE MATERIAl FlOW
Correct fluid nozzle size should be selected for proper
material flow rate. The material valve control knob may
be used to restrict the material needle valve opening and
reduce the material flow as necessary.
CONTROllINg THE FAN SPRAy
The fan spray is controlled by means of the spray pattern
valve control assembly. Turning this control clockwise
until it is closed will give a round spray. Turning it counter-
clockwise will widen the spray into a fan shape. The fan
spray can be turned anywhere through 360
°
by positioning
the air cap relative to the gun. To affect this, loosen retainer
ring, position nozzle, then tighten retainer ring.
TROuBlE SHOOTINg
FAulTy SPRAy
A faulty spray is often caused by improper cleaning result-
ing in dried materials around the material nozzle tip or in
the air nozzle. Soak these parts in thinners to soften the
dried material and remove with a brush or cloth. If either
the air cap or fluid nozzle are damaged, these parts must be
replaced before perfect spray can be obtained.
INTERMITTENT SPRAy
Fluttering spray is caused by one of the following:
1. Insufficient material in cup. Refill the cup.
2. Loose fluid nozzle. Tighten snugly.
3. Cup connection loose or dirt in connection.
Correct as necessary.
4. Air vent in gravity cup blocked. Clear obstruction.
SPRAy guN ClEANINg INSTRuCTIONS
In certain states, spraying solvents which contain Volatile
Organic Compounds (VOC) into the atmosphere when
cleaning a spray gun is now prohibited.
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 cleaner. This system
must totally enclose the spray gun, cups, nozzles and
other parts during washing, rinsing and draining
cycles. This type of unit must be able to flush solvent
through the gun without releasing any VOC vapors
into the atmosphere.
ClEANINg guN ANd gRAvITy FEEd CuP
Remove the cup cover and drain unused material from
cup. Carefully rinse cup with solvent. Place clean solvent
into the cup and spray this through the gun until it is
clean. Remove and clean the cup if necessary. Blow air
through the gun to dry it. (Refer to Service Bulletin SBBI-
4-043 for cleaning instructions when using cup liners.)
caution
Never use metal instruments to clean the air or material
nozzles. These parts are carefully machined and any damage
to them will cause faulty spray.
