SKeep 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.
STo 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.
SNever point guns or applicator nozzles at yourself or other persons.
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:
SPressurized system components
SThe possibility that electrical potentials may remain in the system
after the system was de--energized
SLiquid adhesive vapors
SHydraulically or pneumatically operated system components
SUncovered winding parts
If the system malfunctions, switch it off immediately.
STurn the main switch off, or use emergency stop switch or similar
safety feature as provided.

Manual 56--WM480--MA--02
Allow only qualified personnel to perform the procedures described in this
document. Work should only be carried out on a completely
depressurized system, following all safety procedures.
NOTE: Depending on the configuration of the liquid adhesive application
system, high pressure may remain between application head(s) and
pressure regulator or pump/s even after the system has been switched
off using the main switch or the emergency stop. This especially applies
to multi--hose configurations between pump/s and application head/s.
SPrior to maintenance and repair work it is therefore essential to
ensure that all liquid adhesive application system components are
depressurized as follows:
1. Release input pressure in front of pump by shutting off customer
compressed air supply.
2. Release any remaining system pressure behind the pumps by
manually operating the application heads.
SSecure pneumatically-- and hydraulically--operated equipment against
uncontrolled movement.
SSwitch off system electrically.
WARNING: Some voltage is still present in the control cabinet
even after equipment has been turned off at the main switch.
Complete the following steps prior to maintenance or repair:
1. Disconnect external power supply.
2. Lock out external power supply.
3. Check no voltage is present.
4. Ground and short.
5. Cover nearby live sections.
If liquid adhesive application system is left idle for extended periods (e.g.
overnight or long breaks) Nordson recommends applying Vaseline to the
application head nozzles to prevent them from drying out and becoming
blocked as a result.
SOnly use genuine Nordson parts.

NOTE: Always refer to the liquid adhesive manufacturer’s Material
Safety Data Sheet or material information sheet before working with any
cleaning fluids.
WARNING: Never clean any aluminium part or flush any sy-
stem using halogenated hydrocarbon fluids. Examples of com-
mon halogenated hydrocarbons are: dichloromethylene,
1,1,1--trichloroethylene and perchlorethylene. Halogenated hy-
drocarbons may react violently with aluminium parts.
SNever use an open flame to clean the system or its components.
SCheck that (warm) water can be used to clean the liquid adhesive
system components, possibly with the addition of household
washing--up liquid. If this is not possible, use only the cleaning fluid
stated in the liquid adhesive manufacturer’s information. If the
manufacturer recommends heating the cleaner, note the flash point.
SEnsure sufficient room ventilation to draw off vapors.
WARNING: Fire, open flames and smoking are prohibited
when cleaning fluids are used. Observe all explosion prevention
regulations. Cleaning fluids may only be heated using tempera-
ture controlled and explosion--protected heaters.
SDisposal must be according to the waste key in the DIN Safety Data
Sheet. Liquid adhesives or residue, solvent or separating agents must
not be released into open waterways. In the case of a leak or spillage,
contain liquid and if necessary use an absorbant material e.g.
sawdust to soak it up; then proceed according to the relevant waste
disposal regulations.
SIf the liquid adhesive application system is to be idle for an extended
period, the entire system should be flushed and outlets sealed with
Vaseline. Warm water is usually used to flush application systems
with which water based liquid adhesives are processed.
SIf the liquid adhesive manufacturer specially recommends a flushing
agent, the manufacturer’s safety and disposal details must be
followed.

Manual 56--WM480--MA--02
As there is a wide variety of liquid adhesives available with different
compositions and characteristics, it is impossible here to give an
exhaustive list of safety notes reflecting the typical characteristics of
liquid adhesives. The use of liquid adhesives in Nordson’s liquid adhesive
application systems therefore requires reference to the liquid adhesive
manufacturer’s documents beforehand.
Information relating to safety aspects e.g. concerning solvent content,
hazards and countermeasures in the event of liquid adhesive coming into
contact with skin or mucous membranes are contained in the technical
data sheets and the DIN Safety Data Sheets from the manufacturer.
NOTE:
SAlways refer to the manufacturer’s Material Safety Data Sheet or
material information before working with any liquid adhesives.
SIt may be necessary to refer to the manufacturer’s notes on the use of
materials from a third party. These may be required for processing a
liquid adhesive, but hazards arising from their use are not necessarily
mentioned by the manufacturer of the liquid adhesive.
SLiquid adhesives may still give off vapors when they are processed
correctly. The smell produced can cause some annoyance. This is
especially true where liquid adhesives are used that contain solvent,
thus requiring the use of breathing equipment e.g. a filter.
SIf the prescribed processing conditions are not followed, harmful
decomposition products may develop. Therefore, the vapors must be
removed.
SWash hands well before breaks and when work is finished.
SIf liquid adhesive comes into contact with eyes or mucous
membranes, rinse well with water -- especially the eyes. Change
damp clothes, and seek medical advice if it is swallowed.
SDisposal must be according to the waste key in the DIN Safety Data
Sheet. Liquid adhesives or residue, solvent or separating agents must
not be released into open waterways. In the case of a leak or spillage,
contain liquid and if necessary use an absorbant material e.g.
sawdust to soak it up; then proceed according to the relevant waste
disposal regulations.
SIf solvents or separating agents are used to process a liquid
adhesive, follow the safety and disposal information from the
manufacturer.
