Safety During Repair And Maintenance - SINTERIT LISA X Original User Manual

WARNING!
INERT GAS INSTALLATION
Possibility of unsealing - gas has a suffocating effect on people by displacing
oxygen from the air. Too low oxygen concentration in the air can lead to uncon-
sciousness and death. Inhalation exposure may cause short breath, breathing dif-
ficulties, headaches and dizziness, with high concentrations of gas disorders of
orientation, nausea, fainting, loss of consciousness, and death.
• Store in a well-ventilated place.
• Do not inhale the gas.
• Nitrogen is an inert gas, a natural component of atmospheric air. It is not
harmful in the aquatic environment or soil, its adverse effect is limited to the
displacement of oxygen.
• The built-in oxygen level sensor is not a certified safety device and cannot be
used as the sole alarm in the event of an emergency. Sinterit printers with an
inert gas control system may only be used in well-ventilated areas.
• If the alarm is triggered, turn on the ventilation system or open the windows
and leave the room immediately.
• If you feel any suspicious symptoms, immediately leave the room and go
outside/to a well-ventilated room.
ATTENTION!
If there is a need to discharge the pneumatic energy accumulated in the printer, the pressure hose
supplied to the printer must be disconnected using a quick-release coupling. The pressure will be
equalised to the ambient pressure level.
ATTENTION!
LASER PROTECTIVE GLASS
• The cleaning process of the laser protective glass should be carried out outside of the printer.
• Do not clean the laser protective glass under running water.
• Only use products with ethyl alcohol or isopropyl alcohol (only at 99.9% purity). We recommend
alcohol pads (available in the Dedicated Powder Tools).
ATTENTION!
While the printer is working do not touch any other elements besides: the LCD screen, the emergency
stop pushbutton (E-STOP), the USB port and the power switch.

2.6 Safety during repair and maintenance

WARNING!
• Only trained personnel should carry out repairs.
• Read the user manual carefully before using the printer or doing any
maintenance jobs.
• During cleaning operations, maintenance jobs or when changing parts, the
power switch must be off and the machine must be unplugged by removing
the power cable from the socket.
• During maintenance jobs, affix a notice to the appliance indicating "MACHINE
BEING SERVICED, DO NOT START".
• Do not adjust controls that are not described in the manual.
WARNING!
When restoring original working conditions, the appointed personnel should always make sure
that at the end of the operating procedure, proper printer operation safety conditions are restored,
especially the safety devices and the protective guards.
