Safety

Read and follow these safety instructions. Task- and equipment-specific

warnings, cautions, and instructions are included in equipment

documentation where appropriate.

Make sure all equipment documentation, including these instructions, is

accessible to persons operating or servicing equipment.

Qualified Personnel

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.

Intended Use

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

using incompatible materials

making unauthorized modifications

removing or bypassing safety guards or interlocks

using incompatible or damaged parts

using unapproved auxiliary equipment

operating equipment in excess of maximum ratings

Regulations and Approvals

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.

Personal Safety

To prevent injury follow these instructions.

Do not operate or service equipment unless you are qualified.

Do 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.

Keep 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.

Relieve (bleed off) hydraulic and pneumatic pressure before adjusting or

servicing pressurized systems or components. Disconnect, lock out,

and tag switches before servicing electrical equipment.

While 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.

If 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.

Obtain 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.

Make sure the spray area is adequately ventilated.

To 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 MSDS 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:

Part 1601054-03

2020 Nordson Corporation

WARNING: Any injury caused by high pressure liquid can be serious. If

you are injured or even suspect an injury:

Go to an emergency room immediately.

Tell the doctor that you suspect an injection injury.

Show him this card

Tell 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.

Ground 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.

Shut down all equipment immediately if you notice static sparking or

arcing. Do not restart the equipment until the cause has been identified

and corrected.

Do not smoke, weld, grind, or use open flames where flammable

materials are being used or stored.

Do not heat materials to temperatures above those recommended by

the manufacturer. Make sure heat monitoring and limiting devices are

working properly.

Fire Safety (contd)

Provide adequate ventilation to prevent dangerous concentrations of

volatile particles or vapors. Refer to local codes or your material MSDS

for guidance.

Do not disconnect live electrical circuits when working with flammable

materials. Shut off power at a disconnect switch first to prevent

sparking.

Know 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.

Shut off electrostatic power and ground the charging system before

adjusting, cleaning, or repairing electrostatic equipment.

Clean, maintain, test, and repair equipment according to the instructions

in your equipment documentation.

Use 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 MSDS 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:

Disconnect and lock out system electrical power. Close hydraulic and

pneumatic shutoff valves and relieve pressures.

Identify the reason for the malfunction and correct it before restarting the

system.

Disposal

Dispose of equipment and materials used in operation and servicing

according to local codes.

TrilogyAC Air Spray/LVLP Gravity Fed Manual Spray Guns 5

Part 1601054-03

2020 Nordson Corporation

Description

The Trilogy Automotive Coatings Air Spray and LVLP Gravity Fed Manual

Spray Guns are compressed-air operated low-pressure manual spray guns

for the application of sprayable fluids at air pressures of 2.0−3.5 bar (28−50

psi).

The guns are differentiated by the type of air cap used. A gun may be

converted from Air Spray to LVLP (low volume, low pressure) or vice-versa

simply by changing the air cap. The Air Spray guns are used for

high-decorative surfaces and clear coats where fine atomization is preferred

over flow rate. The LVLP guns are used for high transfer efficiency and

base coats.

Refer to Options for nozzle kits in different sizes, and air compliance caps

and gauge kits to test air flow and ensure compliance with regulations.

Refer to Compliance Kit Installation and Use for instructions.

Also available are adapters that install on the gravity cup fitting for use with

the disposable paint cups of the 3MPPS (Paint Preparation System)

or the HSM SPA-System.
