Maintenance and Repair Practices

 Perform scheduled maintenance activities at the intervals described in this document.

 Relieve system hydraulic and pneumatic pressure before servicing the equipment.

 De-energize the equipment and all auxiliary devices before servicing the equipment.

 Use only new factory-authorized refurbished or replacement parts.

 Read and comply with the manufacturer’s instructions and the MSDS supplied with

equipment cleaning compounds.

NOTE: MSDSs for cleaning compounds that are sold by Nordson are available at

www.nordson.com or by calling your Nordson representative.

 Confirm the correct operation of all safety devices before placing the equipment back into

 Dispose of waste cleaning compounds and residual process materials according to

governing regulations. Refer to the applicable MSDS or contact the authority having

jurisdiction for information.

 Keep equipment safety warning labels clean. Replace worn or damaged labels.

Equipment Safety Information

This equipment safety information is applicable to the following types of Nordson

equipment:

 hot melt and cold adhesive application equipment and all related accessories

 pattern controllers, timers, detection and verification systems, and all other optional

process control devices

Equipment Shutdown

To safely complete many of the procedures described in this document, the equipment must

first be shut down. The level of shut down required varies by the type of equipment in use

and the procedure being completed.

If required, shut down instructions are specified at the start of the procedure. The levels of

shut down are:

Relieving System Hydraulic Pressure

Completely relieve system hydraulic pressure before breaking any hydraulic connection or

seal. Refer to the melter-specific product manual for instructions on relieving system

hydraulic pressure.

De-energizing the System

Isolate the system (melter, hoses, guns, and optional devices) from all power sources

before accessing any unprotected high-voltage wiring or connection point.

1. Turn off the equipment and all auxiliary devices connected to the equipment (system).

2. To prevent the equipment from being accidentally energized, lock and tag the disconnect

switch(es) or circuit breaker(s) that provide input electrical power to the equipment and

optional devices.

NOTE: Government regulations and industry standards dictate specific requirements

for the isolation of hazardous energy sources. Refer to the appropriate regulation or

standard.

Disabling the Guns

All electrical or mechanical devices that provide an activation signal to the guns, gun

solenoid valve(s), or the melter pump must be disabled before work can be performed on or

around a gun that is connected to a pressurized system.

1. Turn off or disconnect the gun triggering device (pattern controller, timer, PLC, etc.).

2. Disconnect the input signal wiring to the gun solenoid valve(s).

3. Reduce the air pressure to the gun solenoid valve(s) to zero; then relieve the residual air

pressure between the regulator and the gun.

Warnings and Cautions

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.

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.

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.
