Fire Safety
To avoid a fire or explosion, follow these instructions.
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.
Provide adequate ventilation to prevent dangerous concentrations of
volatile particles or vapors. Refer to local codes or your material MSDS
for guidance.
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.
Installation and Electrical Connections
Prior to installation, check intended location and surrounding area for
any potential hazards during operation.
All electrical, pneumatic, gas and hydraulic connections and installation
of all system components may only be carried out by qualified
personnel. Observe installation instructions for components and
accessories.
Equipment must be properly grounded and fused according to the rated
current consumption (see ID plate).
Cables which run outside the system must regularly be checked for
wear or damage.
Power supply wire gauge and insulation must be sufficient to handle
rated current consumption.
Cables must never be squeezed or pinched. Do not locate cables or
hoses in high traffic areas.
WARNING: Failure to install the system properly, and especially failure to
ensure electrical, pressurized and high pressure feed connections are made
correctly may result in serious injury or death.

Operation
The system should only be operated when it is in working order. It should
only by operated by qualified persons following all regulations valid for liquid
adhesive systems.
Never allow the system to be operated by personnel under the influence
of substances which reduce their reaction times, or who are not able to
operate the equipment for physical reasons.
Prior to each startup of the system, check protection and warning
devices and make sure they are fully functional. Do not operate the
equipment if these devices are not functioning properly.
When the removal of safety equipment is required for installation,
maintenance or repair, it must be reconnected immediately upon
completion of the work.
In a humid environment, only equipment featuring a corresponding
protection may be operated.
Do not operate the system in an explosive environment.
Keep parts of the body and clothing away from rotating parts. Do not
wear loose articles of clothing when operating or servicing equipment
with rotating parts. Remove wrist watches, rings, necklaces or similar
jewelry and pin up or cover long hair before performing any work on or
with the equipment. The wearing of protective gloves may prove
hazardous in certain circumstances where rotating parts are present and
may therefore be forbidden.
To carry out measurements on the substrate or system components,
switch off parent machine and/or system and wait until the equipment
comes to a standstill.
Never point guns or applicator nozzles at yourself or other persons.

Less-obvious Dangers
WARNING: An operator or service technician working with the equipment
should be aware of the less-obvious dangers that often cannot be
completely minimized at production sites:
Pressurized system components
Exposed surfaces of the unit which cannot be practically safeguarded.
They may be hot and take time to cool after the unit has been operating.
The possibility that electrical potentials may remain in the system after
the system was de-energized
Liquid adhesive vapors or hot melt material and vapors
Hydraulically or pneumatically operated system components
Uncovered winding parts
Danger of Burns
Contact with hot melt materials or hot areas of the unit may produce a
severe skin burn.
WARNING: Hot! Risk of burns. Wear heat-protective clothing, safety
goggles, and/or heat-protective gloves depending on the symbols shown.
Be extremely careful when using hot melt material. Even solidified
material may still be very hot.
Always wear protective clothing which safely covers all exposed parts of
the body.
In case of burns:
Immediately cool affected skin areas using cold, clean water.
Do not forcefully remove hot melt material from the skin.
Immediately seek medical attention.
