Nordson EFD Product Safety Statement (continued)
Fire Safety
To prevent a fire or explosion, follow these instructions:
• 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.
• Provide adequate ventilation to prevent dangerous concentrations of volatile particles or vapors. Refer to local
codes or the SDS 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.
Preventive Maintenance
As part of maintaining continuous trouble-free use of this product, Nordson EFD recommends the following simple
preventive maintenance checks:
• Periodically inspect tube-to-fitting connections for proper fit. Secure as necessary.
• Check tubing for cracks and contamination. Replace tubing as necessary.
• Check all wiring connections for looseness. Tighten as necessary.
• Clean: If a front panel requires cleaning, use a clean, soft, damp rag with a mild detergent cleaner. DO NOT
USE strong solvents (MEK, acetone, THF, etc.) as they will damage the front panel material.
• Maintain: Use only a clean, dry air supply to the unit. The equipment does not require any other regular
maintenance.
• Test: Verify the operation of features and the performance of equipment using the appropriate sections of this
manual. Return faulty or defective units to Nordson EFD for replacement.
• Use only replacement parts that are designed for use with the original equipment. Contact your Nordson EFD
representative for information and advice.

Important Disposable Component Safety Information
All Nordson EFD disposable components, including syringe barrels, cartridges, pistons, tip caps, end caps,
and dispense tips, are precision engineered for one-time use. Attempting to clean and re-use components will
compromise dispensing accuracy and may increase the risk of personal injury.
Always wear appropriate protective equipment and clothing suitable for your dispensing application and adhere to
the following guidelines:
• Do not heat syringe barrels or cartridges to a temperature greater than 38° C (100° F).
• Dispose of components according to local regulations after one-time use.
• Do not clean components with strong solvents (MEK, acetone, THF, etc.).
• Clean cartridge retainer systems and barrel loaders with mild detergents only.
• To prevent fluid waste, use Nordson EFD SmoothFlow
™
pistons.
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:
1. Disconnect and lock out system electrical power. If using hydraulic and pneumatic shutoff valves, close and
relieve pressure.
2. For Nordson EFD air-powered dispensers, remove the syringe barrel from the adapter assembly. For Nordson
EFD electro-mechanical dispensers, slowly unscrew the barrel retainer and remove the barrel from the actuator.
3. 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.
