Personal Safety
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 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.
SWhile operating manual spray guns, make sure you are grounded.
Wear electrically conductive gloves or a grounding strap connected to
the gun handle or other true earth ground. Do not wear or carry metallic
objects such as jewelry or tools.
SIf you receive even a slight electrical shock, shut down all electrical or
electrostatic equipment immediately. Do not restart the equipment until
the problem has been identified and corrected.
SObtain and read Safety Data Sheets (SDS) for all materials used.
Follow the manufacturer’s instructions for safe handling and use of
materials, and use recommended personal protection devices.
SMake sure the spray area is adequately ventilated.
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.
High-Pressure Fluids
High-pressure fluids, unless they are safely contained, are extremely
hazardous. Always relieve fluid pressure before adjusting or servicing high
pressure equipment. A jet of high-pressure fluid can cut like a knife and
cause serious bodily injury, amputation, or death. Fluids penetrating the
skin can also cause toxic poisoning.
If you suffer a fluid injection injury, seek medical care immediately. If
possible, provide a copy of the SDS for the injected fluid to the health care
provider.
The National Spray Equipment Manufacturers Association has created a
wallet card that you should carry when you are operating high-pressure
spray equipment. These cards are supplied with your equipment. The
following is the text of this card:

TrilogyrAir-Assisted Airless LT Manual Spray Gun 3
Part 1601052-03
E2016 Nordson Corporation
WARNING: Any injury caused by high pressure liquid can be serious. If
you are injured or even suspect an injury:
SGo to an emergency room immediately.
STell the doctor that you suspect an injection injury.
SShow him this card
STell him what kind of material you were spraying
MEDICAL ALERT—AIRLESS SPRAY WOUNDS: NOTE TO PHYSICIAN
Injection in the skin is a serious traumatic injury. It is important to treat the
injury surgically as soon as possible. Do not delay treatment to research
toxicity. Toxicity is a concern with some exotic coatings injected directly into
the bloodstream.
Consultation with a plastic surgeon or a reconstructive hand surgeon may
be advisable.
The seriousness of the wound depends on where the injury is on the body,
whether the substance hit something on its way in and deflected causing
more damage, and many other variables including skin microflora residing
in the paint or gun which are blasted into the wound. If the injected paint
contains acrylic latex and titanium dioxide that damage the tissue’s
resistance to infection, bacterial growth will flourish. The treatment that
doctors recommend for an injection injury to the hand includes immediate
decompression of the closed vascular compartments of the hand to release
the underlying tissue distended by the injected paint, judicious wound
debridement, and immediate antibiotic treatment.
Fire Safety
To avoid a fire or explosion, follow these instructions.
SGround all conductive equipment. Use only grounded air and fluid
hoses. Check equipment and workpiece grounding devices regularly.
Resistance to ground must not exceed one megohm.
SShut down all equipment immediately if you notice static sparking or
arcing. Do not restart the equipment until the cause has been identified
and corrected.
SDo not smoke, weld, grind, or use open flames where flammable
materials are being used or stored.
SDo not heat materials to temperatures above those recommended by
the manufacturer. Make sure heat monitoring and limiting devices are
working properly.

Part 1601052-03 E2016 Nordson Corporation
Fire Safety (contd)
SProvide adequate ventilation to prevent dangerous concentrations of
volatile particles or vapors. Refer to local codes or your material SDS
for guidance.
SDo not disconnect live electrical circuits when 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.
SShut off electrostatic power and ground the charging system before
adjusting, cleaning, or repairing electrostatic equipment.
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.
Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that
contains aluminum components. Under pressure, these solvents can react
with aluminum and explode, causing injury, death, or property damage.
Halogenated hydrocarbon solvents contain one or more of the following
elements:
Element Symbol Prefix
Fluorine F “Fluoro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
Check your material SDS or contact your material supplier for more
information. If you must use halogenated hydrocarbon solvents, contact
your Nordson representative for information about compatible Nordson
components.
Action in the Event of a Malfunction
If a system or any equipment in a system malfunctions, shut off the system
immediately and perform the following steps:
SDisconnect and lock out system electrical power. Close hydraulic and
pneumatic shutoff valves and relieve pressures.
SIdentify the reason for the malfunction and correct it before restarting the
system.

Coating Tips
See Figure 3. Use these tips to help you obtain a quality coating:
SHold the spray gun at a 90 degree angle to the surface being coated. If
held at a different angle, the coverage will be uneven and flawed.
SUse your arm, not your wrist, to move the gun parallel to the surface.
Do not wave the gun with your wrist.
SBegin moving the gun before pulling the trigger. Move the gun back and
forth at an even speed. This will ensure even, smooth overlapping
patterns without any buildup where the trigger is pulled.
SRelease the trigger before stopping arm movements.
SImmerse the gun nozzle in solvent or waterborne cleaning solution
during pauses in production to prevent coating material from hardening
on the nozzle.
