Repair
It is imperative to follow the safety instructions outlined in this manual. Refer to
Safety
for
additional information. Contact a Nordson® representative regarding these procedures (if
necessary).
WARNING:
• Safety glasses are to be worn at all times while installing, servicing, operating, or
observing equipment. The sudden release of air or fluid can cause damage to eyes.
•
Allow only qualified personnel to perform the following tasks. Follow the safety
instructions in this document and all other related documentation.
• Do not remove any covers during operation. The moving parts under these covers
could cause injury to personnel.
• Relieve system and material pressure before disconnecting hoses.
•
Shut off and lock out power to the smart gun prior to performing repair procedures.
•
If used, turn off any temperature control unit.
•
Never exceed the maximum operating temperature of 180˚F (82˚C).
NOTE:
Any material injected into flesh can cause severe injury or death. Keep body
parts away from material discharge ports. If injection occurs, seek medical attention
immediately.
WARNING:
Operating faulty electrostatic equipment is hazardous and can cause
electrocution, fire, or explosion. Make resistance checks part of your periodic
maintenance program. If you receive even a slight electrical shock or notice static
sparking or arcing, shut down all electrical or electrostatic equipment immediately. Do
not restart the equipment until the problem has been identified and corrected.
CAUTION:
• Relieve air and material pressure when equipment is not in use for prolonged periods
of time. Do not allow pressure to remain static when equipment is idle as this may
cause material to pack and harden.
• Do not use silicone based lubricants with a smart gun. The use of silicone based
lubricants can promote seal failure.
•
The surface of the smart gun needles are ground to specification and should be
protected from damage during handling. Scratches, dents, and other damage should
be avoided or repaired to obtain the maximum life of the valve seals and bearings.
