WARNING: Hazardous vapors! Before processing any polyurethane
reactive (PUR) hot melt or solvent-based material through a
compatible Nordson melter, read and comply with the material’s
MSDS. Ensure that the material’s processing temperature and
flashpoints will not be exceeded and that all requirements for safe
handling, ventilation, first aid, and personal protective equipment are
met. Failure to comply with MSDS requirements can cause personal
injury, including death.
HM
WARNING: Reactive material! Never clean any aluminum component
or flush Nordson equipment with halogenated hydrocarbon fluids.
Nordson melters and guns contain aluminum components that may
react violently with halogenated hydrocarbons. The use of
halogenated hydrocarbon compounds in Nordson equipment can
cause personal injury, including death.
HM, CA
WARNING: System pressurized! Relieve system hydraulic pressure
before breaking any hydraulic connection or seal. Failure to relieve
the system hydraulic pressure can result in the uncontrolled release
of hot melt or cold adhesive, causing personal injury.
HM
WARNING: Molten material! Wear eye or face protection, clothing
that protects exposed skin, and heat-protective gloves when servicing
equipment that contains molten hot melt. Even when solidified, hot
melt can still cause burns. Failure to wear appropriate personal
protective equipment can result in personal injury.

Warning or Caution
HM, PC
WARNING: Equipment starts automatically! Remote triggering
devices are used to control automatic hot melt guns. Before working
on or near an operating gun, disable the gun’s triggering device and
remove the air supply to the gun’s solenoid valve(s). Failure to disable
the gun’s triggering device and remove the supply of air to the
solenoid valve(s) can result in personal injury.
HM, CA, PC
WARNING: Risk of electrocution! Even when switched off and
electrically isolated at the disconnect switch or circuit breaker, the
equipment may still be connected to energized auxiliary devices.
De-energize and electrically isolate all auxiliary devices before
servicing the equipment. Failure to properly isolate electrical power to
auxiliary equipment before servicing the equipment can result in
personal injury, including death.
HM, CA, PC
WARNING: Risk of fire or explosion! Nordson adhesive equipment is
not rated for use in explosive environments and should not be used
with solvent-based adhesives that can create an explosive
atmosphere when processed. Refer to the MSDS for the adhesive to
determine its processing characteristics and limitations. The use of
incompatible solvent-based adhesives or the improper processing of
solvent-based adhesives can result in personal injury, including death.
HM, CA, PC
WARNING: Allow only personnel with appropriate training and
experience to operate or service the equipment. The use of untrained
or inexperienced personnel to operate or service the equipment can
result in injury, including death, to themselves and others and can
damage to the equipment.

Warning or Caution
HM
CAUTION: Hot surfaces! Avoid contact with the hot metal surfaces of
guns, hoses, and certain components of the melter. If contact can not
be avoided, wear heat-protective gloves and clothing when working
around heated equipment. Failure to avoid contact with hot metal
surfaces can result in personal injury.
HM
CAUTION: Some Nordson melters are specifically designed to
process polyurethane reactive (PUR) hot melt. Attempting to process
PUR in equipment not specifically designed for this purpose can
damage the equipment and cause premature reaction of the hot melt.
If you are unsure of the equipment’s ability to process PUR, contact
your Nordson representative for assistance.
HM, CA
CAUTION: Before using any cleaning or flushing compound on or in
the equipment, read and comply with the manufacturer’s instructions
and the MSDS supplied with the compound. Some cleaning
compounds can react unpredictably with hot melt or cold adhesive,
resulting in damage to the equipment.
HM
CAUTION: Nordson hot melt equipment is factory tested with
Nordson Type R fluid that contains polyester adipate plasticizer.
Certain hot melt materials can react with Type R fluid and form a solid
gum that can clog the equipment. Before using the equipment,
confirm that the hot melt is compatible with Type R fluid.
Other Safety Precautions
Do not use an open flame to heat hot melt system components.
Check high pressure hoses daily for signs of excessive wear, damage,
or leaks.
Never point a dispensing handgun at yourself or others.
Suspend dispensing handguns by their proper suspension point.
