While this manual lists standard specifications
and service procedures, some minor deviations
may be found between this literature and your
equipment. Differences in local codes and plant
requirements, material delivery requirements,
etc., make such variations inevitable. Compare
this manual with your system installation draw-
ings and appropriate Ransburg equipment
manuals to reconcile such differences.
Careful study and continued use of this manual
will provide a better understanding of the equip-
ment and process, resulting in more efficient op-
eration, longer trouble-free service and faster,
easier troubleshooting. If you do not have the
manuals and safety literature for your Ransburg
system, contact your local Ransburg represen-
tative or Ransburg.

Fire Hazard
Improper or inadequate operation
and maintenance procedures will
cause a fire hazard.
Protection against inadvertent
arcing that is capable of causing
fire or explosion is lost if any
safety interlocks are disabled
during operation. Frequent
power supply shutdown indicates
a problem in the system requir-
ing correction.
Fire extinguishing equipment must be present in the
spray area and tested periodically.
Spray areas must be kept clean to prevent the
accumulation of combustible residues.
Smoking must never be allowed in the spray area.
The high voltage supplied to the atomizer must be
turned off prior to cleaning, flushing, or maintenance.
When using solvents for cleaning:
Those used for equipment flushing should have flash
points equal to or higher than those of the coating
material.
Those used for general cleaning must have flash
points above 100oF (37.8oC).
Spray booth ventilation must be kept at the rates
required by NFPA 33, OSHA and local codes. In
addition, ventilation must be maintained during
cleaning operations using flammable or combustible
solvents.
Electrostatic arcing must be prevented.
Test only in areas free of combustible material.
Testing may require high voltage to be on, but only as
instructed.
Non-factory replacement parts or unauthorized
equipment modifications may cause fire or injury.
If used, the key switch bypass is intended for use
only during setup operations. Production should
never be done with safety interlocks disabled.
Never use equipment intended for use in waterborne
installations to spray solvent based materials.

Halogenated hydrocarbon solvents
for example: methylene chloride
and 1,1,1,-Trichloroethane are not
chemically compatible with the
aluminum that might be used in
many system components. The
chemical reaction caused by these
solvents reacting with aluminum
can become violent and lead to an
equipment explosion.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum equipment
during spraying, flushing, or cleaning. Read the label
or data sheet for the material you intend to spray. If
in doubt as to whether or not a coating or cleaning
material is compatible, contact your material supplier.
Any other type of solvent may be used with aluminum
equipment.
Use of hand tools may cause
cumulative trauma disorders
(CTD's). CTD's or musculoskel-
etal disorders, involve damage to
the hands, wrists, elbows, shoul-
ders, neck and back. Carpal
tunnel syndrome and tendinitis
(such as tennis elbow or rotator
cuff syndrome) are examples of
CTD's.
CTD's when using hand tools,
tend to affect the upper extremi-
ties. Factors which may in-
crease the risk of developing a
CTD include:
1. High frequency of the activity.
2. Excessive force, such as
gripping, pinching or pressing
with the hands and fingers.
3. Extreme or awkward finger,
wrist or arm positions.
4. Excessive duration of the
activity.
5. Tool vibration.
6. Repeated pressure on a
body part.
7. Working in cold temperatures.
Risk is reduced by avoiding or lessening the listed
hazards.
CTD's can also be caused by such activities as
sewing, golf, tennis and bowling, to name a few.
Pain, tingling, or numbness in the shoulder, fore-
arm, wrists, hands, or fingers, especially during the
night, may be early symptoms of a CTD. Do not
ignore them. Should you experience any such
symptoms, see a physician immediately. Other
early symptoms may include vague discomfort in
the hand, loss of manual dexterity, and non-spe-
cific pain in the arm. Ignoring early symptoms and
continued repetitive use of the arm, wrist and hand
can lead to serious disability.

THE PROCESSTHE PROCESS
THE PROCESSTHE PROCESS
THE PROCESS
This is a method of applying electrostatically at-
omized coating material. The No. 2 Process
Handgun System applies a high voltage, DC
negative charge to the applicator bell, creating
an electrostatic field between the bell and the
target object. The target is electrically grounded
through its support (which may be stationary or
moving) or through an electrical connection to a
known earth ground.
A regulated pressure fluid system delivers
coating material to the bell when the gun is
triggered. There, the fluid travels across the
face of the rotating bell and is charged. The
fluid is atomized at the edge of the bell forming a
fine mist, which under the influence of the
electrostatic field is attracted to and deposited
on the target object. The forces between the
charged particles and the grounded target are
sufficient to turn most normal overspray around
and deposit it on the rear surface of the target.
Therefore, most of the spray is deposited and
overspray is controlled. This process makes
the No. 2 Process Handgun one of the most
efficient electrostatic spray products on the
market.
The No. 2 Process Handgun applies a DC
negative charge to the coating materials at the
point of atomization. The electrostatic charge
allows a more efficient, uniform application of
coating material to the front, edges, sides, and
back of products, making it highly suitable for
applying coatings to a variety of surface con-
figurations; large targets, tubular products, small
parts, fencing, etc. Because it is a grounded
fluid system, it is highly suitable for applying a
wide range of solvent reduced coatings such as
enamels, epoxies, etc.
One of the many features of the No. 2 Process
Handgun is that the electrical discharge, which
is available from the resistive charging brush, is
limited to the optimum combination of safety and
efficiency.
The No. 2 Process Handgun System includes
the Hand Gun, the High Voltage Power Supply,
the High Voltage Cable, and Fluid Hose.
