2.3.2 Misuse
Some examples of misuse of the 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
2.4 Basic Safety Precautions and Practices
Compliance with the following recommended precautions and practices reduces the risk of personal
injury or damage to property during dispensing system operation and maintenance.
WARNING! Failure to comply with any of the safety recommendations could cause serious
injury to the user or damage to the dispensing system.
2.4.1 Safety of Personnel
• Only trained personnel should be permitted to perform operation, maintenance, and
troubleshooting procedures.
• There should always be a second person present when performing maintenance on a system
under power.
• Locate, identify, and obey all safety warning labels on your system before initial use, see
2.10 Safety Warning Labels.
• Immediately push the red Emergency Machine Off (EMO) button if personnel are in danger
of being injured.
• Lockout/Tagout (LOTO) power and disconnect facility air to the dispensing system before
performing service or maintenance on the dispensing system, see 2.14 Service Shutdown.
• Lockout/Tagout (LOTO) power to upstream and downstream machines before performing
service or maintenance on the dispensing system.
• Unplug power source before performing service or maintenance on the dispensing system.
• When using conveyorized machines as standalone equipment (not inline), make sure the
machine is configured with the optional conveyor closeout kit (Item 38) to prevent personal
injury and equipment/workpiece damage.
• Do not wear loose clothing or jewelry while operating the system. Tie back long hair to
prevent it from being caught in moving parts.

• Do not touch the dispensing head or other moving parts while the dispensing system is
operating.
• To prevent burn injury, wear thermal gloves when working around heater tooling and fluid
heaters.
• If your system is equipped with a laser height sensor, use extreme care to avoid looking
directly at the laser beam or its reflection off of mirror-like surfaces, see 2.8 Laser
Radiation.
• Make sure the main power cable and main air supply hose are securely connected before
operating the dispensing system.
• If in a confined room, ensure adequate and uninterrupted air ventilation, and heating and
cooling meet environmental stress limits of personnel and the dispensing system.
• Where Volatile Organic Compound (VOC) emissions can exceed safe limits, facility
ventilation and filtration systems must be operational.
• Provide adequate space around the dispensing system to allow for movement of
maintenance and service personnel. Allow space for access doors and service panels to open
fully.
• Make sure all facility power sources are safely grounded.
• Routinely inspect all air hoses and electrical cables for damage.
• Make sure power cords and air supply hoses do not cross a walkway or aisle.
• Before attempting to lift a load, take into consideration facility lifting and transport
precautions, see 2.7 Lifting and Transport Precautions.
• Maintain a clean and orderly work area.
2.4.2 Material Safety
• Follow Safety Data Sheet (SDS) recommendations for the proper handling, cleanup, and
disposal of all materials and fluids and their containers (i.e., syringes, cups, reservoirs, etc.)
used with the dispensing system.
• Obtain the SDS from the applicable chemical supplier for chemical substances not provided
with the equipment. These chemical substances include those used for processing,
maintenance, and service of the equipment.
• Follow SDS recommendations for the proper handling and disposal of all materials used for
cleaning dispensing equipment and spills.
• Make sure the dispensing system ventilation is ON during handling and cleanup of all
materials used with the dispensing system.
• Know the SDS recommendations for treatment of injury resulting from exposure to
hazardous materials.
• Always wear appropriate Personal Protective Equipment (PPE) as recommended by facility
safety practices and the material manufacturer’s SDS.
• When working with multiple fluids, refer to the SDS to ensure the materials are compatible.

• If possible, save or recycle unused materials. Refer to the SDS before saving or recycling
unused materials.
• Do NOT dispense fluids with a flash point less than 93 °C.
• DO NOT dispense toxic fluids (materials with a TLV of 200 ppm or lower).
2.4.3 Preventing Dispensing System and Workpiece Damage
• Immediately push the EMO button if dispensing system or a workpiece is in danger of
being damaged.
• Use standard Electrostatic Discharge (ESD) precautions when working near sensitive
components. Always wear a grounding strap and connect it to the ESD ground before
handling workpieces.
• Immediately contain and clean up any caustic or conductive fluid spills as recommended in
the material manufacturer’s SDS. If fluid gets into internal portions of the machine,
immediately contact Asymtek Technical Support.
• Follow all recommended system maintenance procedures.
• Always keep the dispensing area clear of any fallen workpieces or obstacles.
• Ensure that no air intakes or exhaust grilles are blocked when the system is in operation.
2.5 Decommissioning
The dispensing system should provide you with years of safe and reliable service. When it is necessary to
decommission the system, the components should be dispositioned as specified in Table 2-1.
