Comply with appropriate local, state, and national
codes governing ventilation, fire protection, operation maintenance, and housekeeping. Reference
OSHA, NFPA 33, and your insurance company requirements.
Always turn power to the power supply OFF, unplug the electrical cord from its outlet, and remove
the front panel fuse, before opening the power supply door. If necessary, lock the power supply out
so that it cannot be turned ON until the work is finished.
Whenever removing high voltage cables from
equipment, ground the contact end of the cable by
holding the cable such that the contact touches
earth ground for several seconds. Do not touch
the contact until it has been grounded. This will
reduce the possibility of residual charge causing
electrical shock.
The High Voltage Multiplier Assembly contains energy storage components that can cause serious
shock injury, and therefore is not field repairable.
Warranty will be voided if the High Voltage Multiplier seal is broken. If the High Voltage Multiplier
is defective contact your authorized ITW Ransburg
representative for exchange or repair.
The High Voltage Multiplier and high voltage cable
contain significant capacitance that will store
charge. Allow approximately 10 seconds for this
charge to bleed off before opening the cabinet door
or removing the high voltage cable from the power
supply or spray gun.

(CTD's). CTD's or musculoskeletal disorders, involve damage to
the hands, wrists, elbows, shoulders, 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 extremities. Factors which may increase 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.
SAFEGUARDSSAFEGUARDS

SAFEGUARDSSAFEGUARDS
Tells how to avoid the hazard.
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, forearm, 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 nonspecific
pain in the arm. Ignoring early symptoms and continued repetitive use of the arm, wrist and hand can
lead to serious disability.

Electrostatic Mix ProcessElectrostatic Mix Process
Electrostatic Mix Process
Electrostatic Mix ProcessElectrostatic Mix Process
This is a combined air/airless method for electrostatically applying coatings to objects. The
M90 system applies a high voltage DC charge
to the applicator electrode, creating an electrostatic field between the electrode and the
grounded target. The target is electrically
grounded through its support which may be either stationary or moving.
A regulated high pressure fluid system delivers
coating material to the fluid nozzle and is atomized by passing through an orifice under pressure. The atomized spray particles become
electrically charged under the influence of the
electrostatic field surrounding the nozzle. The
air supply to the gun aids in shaping the coating
material into a desired pattern. The charged
particles are 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 back surface of the target. Therefore, a high percentage of the coating is deposited on the target.
A control unit provides either manual or automatic operation of the equipment. Controls normally include, but are not limited to, fan and conveyor interlocks and a protective current overload device.

(Cascade / Classic)(Cascade / Classic)
The M90 Hand Gun applies a negative 85 kV
DC charge to the coating materials at the point
of atomization. This electrostatic charge allows
a more efficient, uniform application of coating to
the front, edges, sides, and back of products.
The M90 system is highly suitable for applying
coatings to a variety of surface configurations;
large targets, small parts, tubular wares, concave and recessed parts, etc. Because it is a
grounded fluid system, it is highly suitable for
applying a wide range of solvent reduced coatings such as enamels, lacquers, epoxies, etc.
The M90 Handgun system includes the Handgun, Cable, Air and Fluid Hoses, and a Control
Unit.
The Cascade Control Unit provides low voltage
output to the gun and contains controls for AC
on/off, high voltage adjust, kV and microamp
meter.
The Classic Control Unit provides high voltage
output to the gun and contains controls for AC
on/off, high voltage adjust, kV and microamp
meter.

The M90 may be used with the Aviator power
generator in hazardous locations. This equipment meets Class 1, Division 1, Group D hazardous location requirements. This allows moving the M90 power source inside most spray
booths or areas where the standard control unit
may not be conveniently located. Examples are
airplane hangers, etc.

> Verify that the gun handle is actually
grounded before operating it! This is done
with a fully connected and operational system, by placing one lead of an ohmmeter to
the handle and the other to the building
electrical ground (cold water pipe, building
structure, steel, etc.). They should be
essentially zero.
> If a greater reading is obtained, check
that the control unit is grounded. (See the
control unit manual for grounding procedure.)

• Ground all operators by requiring that they
hold the gun handle with a bare hand.
• Ground operators and all other persons in
spray areas by requiring that they wear conductive soled shoes or grounding straps.
• Have exhaust fans operating while spraying.
• Exhaust fans must be interlocked with the
control unit or Aviator.
• See that no more than one gallon of solvent
per safety container per operator is inside of
the hazard location.
• If ANY symptom of improper operation occurs,
suspend use of the unit until the problem has
been diagnosed and corrected. See Figure 1
"Troubleshooting Guide" or contact your authorized ITW Ransburg representative.
• Ground MUST be maintained during the addition of fluid to any supply container! Whenever transferring flammable fluid from one container to another, both containers MUST be
properly connected to a proven ground first
and then to each other. Personnel executing
such a transfer MUST also be grounded.
• A chemical reaction, resulting in the possibility
of a pressure EXPLOSION, may occur if 1, 1,
1-Trichloroethane, Methylene Chloride, or
other Halogenated Hydrocarbon Solvents are
used in PRESSURIZABLE FLUID SYSTEMS
having ALUMINUM or GALVANIZED WETTED PARTS. Such an explosion could cause
DEATH, serious BODILY INJURY and/or
substantial property damage. Consult your
fluid supplier to determine the chemical content of your solvents. (See SL-81-05 "HHC
Explosion Hazard Danger Sign" and SL-81-08
"Halogenated Hydrocarbon Safety Bulletin".)

• Never flush the gun with solvent while electrostatics are on. Failure to turn off electrostatics
while flushing may cause an IGNITION HAZARD.

Following are some basic electrostatic spray
techniques. Depending on the spray target, it
may be necessary to adjust the technique.
Spray Width DeterminationSpray Width Determination
Spray Width Determination
Spray Width DeterminationSpray Width Determination
The size of the object being coated is the determining factor in adjusting the spray pattern. The
larger the object, the larger the required pattern
width. This is accomplished by fluid nozzle selection. Air adjustment is used to remove "tails"
from the spray pattern.

> The degree of atomization is depen-
dent on the viscosity of the paint formulation, the applied fluid pressure, and nozzle
selection.

The distance between the gun and the target
influences the appearance of the final finish of
the object. If the gun is held too close (under 4
inches), runs and sags with excessive "bounceback" may occur. If the gun is held too far from
the object, the electrostatic attraction is decreased. Normally, the best spacing between
gun and target is in the 6 to 12 inch area.
