warnings, cautions, and instructions are included in equipment
documentation where appropriate.
Make sure all equipment documentation, including these instructions, is
accessible to all persons operating or servicing equipment.
Equipment owners are responsible for making sure that Nordson
equipment is installed, operated, and serviced by qualified personnel.
Qualified personnel are those employees or contractors who are trained
to safely perform their assigned tasks. They are familiar with all relevant
safety rules and regulations and are physically capable of performing
their assigned tasks.
Use of Nordson equipment in ways other than those described in the
documentation supplied with the equipment may result in injury to
persons or damage to property.
Some examples of unintended use of equipment include
Susing incompatible materials
Smaking unauthorized modifications
Sremoving or bypassing safety guards or interlocks
Susing incompatible or damaged parts
Susing unapproved auxiliary equipment
Soperating equipment in excess of maximum ratings
Make sure all equipment is rated and approved for the environment in
which it is used. Any approvals obtained for Nordson equipment will be
voided if instructions for installation, operation, and service are not
followed.
All phases of equipment installation must comply with all Federal, State,
and Local codes.

To prevent injury follow these instructions.
SDo not operate or service equipment unless you are qualified.
SDo not operate equipment unless safety guards, doors, or covers are
intact and automatic interlocks are operating properly. Do not bypass
or disarm any safety devices.
SKeep clear of moving equipment. Before adjusting or servicing any
moving equipment, shut off the power supply and wait until the
equipment comes to a complete stop. Lock out power and secure the
equipment to prevent unexpected movement.
SRelieve (bleed off) hydraulic and pneumatic pressure before adjusting
or servicing pressurized systems or components. Disconnect, lock
out, and tag switches before servicing electrical equipment.
SObtain and read Material Safety Data Sheets (MSDS) for all materials
used. Follow the manufacturer’s instructions for safe handling and
use of materials, and use recommended personal protection devices.
STo prevent injury, be aware of less-obvious dangers in the workplace
that often cannot be completely eliminated, such as hot surfaces,
sharp edges, energized electrical circuits, and moving parts that
cannot be enclosed or otherwise guarded for practical reasons.
To avoid a fire or explosion, follow these instructions.
SDo not smoke, weld, grind, or use open flames where flammable
materials are being used or stored.
SProvide adequate ventilation to prevent dangerous concentrations of
volatile materials or vapors. Refer to local codes or your material
MSDS for guidance.
SDo not disconnect live electrical circuits while working with flammable
materials. Shut off power at a disconnect switch first to prevent
sparking.

SKnow where emergency stop buttons, shutoff valves, and fire
extinguishers are located. If a fire starts in a spray booth,
immediately shut off the spray system and exhaust fans.
SClean, maintain, test, and repair equipment according to the
instructions in your equipment documentation.
SUse only replacement parts that are designed for use with original
equipment. Contact your Nordson representative for parts
information and advice.
All work conducted inside the spray booth or within 1 m (3 ft) of booth
openings is considered within a Class 2, Division 1 or 2 Hazardous
location and must comply with NFPA 33, NFPA 70 (NEC articles 500,
502, and 516), and NFPA 77, latest conditions.
SAll electrically conductive objects in the spray areas shall be
electrically connected to ground with a resistance of not more than 1
megohm as measured with an instrument that applies at least 500
volts to the circuit being evaluated.
SEquipment to be grounded includes, but is not limited to, the floor of
the spray area, operator’s platform, hoppers, photoeye supports, and
metal blow-off nozzles. Personnel working in the spray area must be
grounded.
SThere is a possible ignition potential from the charged human body.
Personnel standing on a painted surface, such as the operator
platform, or wearing non-conductive shoes, are not grounded.
Personnel must wear shoes with conductive soles or use a ground
strap to maintain a connection to ground when working with or around
electrostatic equipment.
SOperators must maintain skin-to-metal contact between their hand
and the gun handle to prevent shocks while operating manual
electrostatic spray guns. If gloves must be worn, cut away the palm
or fingers, wear electrically conductive gloves, or wear a grounding
strap connected to the gun handle or other true earth ground.

SShut off electrostatic power supplies and ground gun electrodes
before making adjustments or cleaning powder spray guns.
SConnect all disconnected equipment, ground cables, and wires after
servicing equipment.
WARNING: Operating faulty electrostatic equipment is
hazardous and can cause electrocution, fire, or explosion.
Make resistance checks part of your periodic maintenance
program. If you receive even a slight electrical shock or notice
static sparking or arcing, shut down all electrical or electrostatic
equipment immediately. Do not restart the equipment until the
problem has been identified and corrected.
If a system or any equipment in a system malfunctions, shut off the
system immediately and perform the following steps:
SDisconnect and lock out electrical power. Close pneumatic shutoff
valves and relieve pressures.
SIdentify the reason for the malfunction and correct it before restarting
the equipment.
Dispose of equipment and materials used in operation and servicing
according to local codes.

Tribomatic Magnum Automatic Powder Spray Gun 5

All rights reserved 343 547A
Issued 8/00
Manual 37-37
The Tribomatic Automatic Powder Spray Gun uses friction (the tribo
effect) to electrostatically charge powder coating particles as they are
forced through the gun by compressed air. The gun is used with a
Tribomatic Magnum control unit.
See Figure 1. The gun consists of a chargetube (4), diffuser (1), and a
spacer (5). The gun mount (3) is used to mount the gun to a reciprocator,
oscillator, or a fixed gun stand.

Flow-rate air pumps powder out of the feed hopper and forces it through
the feed hose into the diffuser. Diffuser air mixes with the powder and
increases its speed. The powder and air mixture then passes through a
group of spiral tubes inside the chargetube. The collision of the powder
particles with the walls of the tubes electrostatically charges both the
powder particles and the tubes’ inner surface.

The tubes are grounded through the gun body, ground wire, and the
control unit. The charge picked up by the tubes is displayed in
microampheres at the control unit. The display indicates how well the
powder is charging (the higher the number, the stronger the charge the
powder is receiving). The strength of the charge the powder receives will
vary depending on many factors, including the powder type and its speed
through the gun.
Refer to Table 1.
