Section 1
Safety
Read and follow these safety instructions. Task- and equipment-specific
warnings, cautions, and instructions are included in equipment
documentation where appropriate.
Make sure all equipment documentation, including these instructions, is
accessible to all persons operating or servicing equipment.
Equipment owners are responsible for making sure that Nordson
equipment is installed, operated, and serviced by qualified personnel.
Qualified personnel are those employees or contractors who are trained
to safely perform their assigned tasks. They are familiar with all relevant
safety rules and regulations and are physically capable of performing
their assigned tasks.
Use of Nordson equipment in ways other than those described in the
documentation supplied with the equipment may result in injury to
persons or damage to property.
Some examples of unintended use of equipment include
using incompatible materials
making unauthorized modifications
removing or bypassing safety guards or interlocks
using incompatible or damaged parts
using unapproved auxiliary equipment
operating equipment in excess of maximum ratings
Make sure all equipment is rated and approved for the environment in
which it is used. Any approvals obtained for Nordson equipment will be
voided if instructions for installation, operation, and service are not
followed.
All phases of equipment installation must comply with all Federal, State,
and Local codes.

To prevent injury follow these instructions.
Do not operate or service equipment unless you are qualified.
Do not operate equipment unless safety guards, doors, or covers are
intact and automatic interlocks are operating properly. Do not bypass
or disarm any safety devices.
Keep clear of moving equipment. Before adjusting or servicing any
moving equipment, shut off the power supply and wait until the
equipment comes to a complete stop. Lock out power and secure the
equipment to prevent unexpected movement.
Relieve (bleed off) hydraulic and pneumatic pressure before adjusting
or servicing pressurized systems or components. Disconnect, lock
out, and tag switches before servicing electrical equipment.
Obtain and read Material Safety Data Sheets (MSDS) for all materials
used. Follow the manufacturer’s instructions for safe handling and
use of materials, and use recommended personal protection devices.
To prevent injury, be aware of less-obvious dangers in the workplace
that often cannot be completely eliminated, such as hot surfaces,
sharp edges, energized electrical circuits, and moving parts that
cannot be enclosed or otherwise guarded for practical reasons.
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.
Provide adequate ventilation to prevent dangerous concentrations of
volatile materials or vapors. Refer to local codes or your material
MSDS for guidance.
Do not disconnect live electrical circuits while working with flammable
materials. Shut off power at a disconnect switch first to prevent
sparking.
