•
Do not laser heat-sensitive surfaces or materials that may generate toxic fumes, such as PVC and Teflon.
•
Regularly clean and maintain your machine according to our cleaning and maintenance Instructions in
Chapter 8. Doing so will ensure your machine will operate effectively and safely over a long period of time.
1.5.2 Safety Notice for Class 4 Machine
When the optional Pass-Through door module is installed, the laser system becomes a Class 4 machine with front
and rear doors open, machine operators must wear goggles and follow the safety instructions to operate the
machine.
Exposure to a Class 4 laser beam via direct radiation and indirect stray radiation may cause damage to both skin and
eyes. Exposure to the Class 4 laser beam may cause ignition of combustible materials which can lead to a fire. A
proper and well-maintained fire extinguisher should keep on hand next to the laser machine all the times.
The machine operator is responsible to take all necessary protective measures to prevent he possible ignition or
explosion of materials by the laser beam. A Class 4 laser system should be operated according to the following
precautionary measures among others:
• The operator is obliged to appoint a trained Laser Protection Officer responsible for compliance with the
relevant regulations.
• Identify the danger zone by installing warning lights and warning signs outside the area.
• The danger zone must be secured against unauthorized access.
• The operator of a Class 4 laser system should always wear laser protection goggles suitable for the laser
wavelength in use and with optical density at least OD5+ within the danger zone.
• An additional warning light should also be installed in a visible location to warn the machine operator of any
emerging laser radiation.
1.6 Operating Environment
Please follow the guidelines when considering a suitable location to set the LV-290. Improper work environments
may lead to operational malfunction and/or unsafe working conditions. The LV-290 should be placed and operated
in a standard office-type environment.
• Avoid environments where the machine is exposed to high levels of dust, temperature (temperature exceeding
30°C or 85°F) or humidity (humidity exceeding 70% or where the ambient temperature is near the dew point).
• Avoid small, enclosed areas with poor ventilation.
• Avoid areas with high levels of noise and electrical noise.
• Select a location that is large enough to accommodate the LV-290, an exhaust system, a computer and a work or
storage table.
• Select a location in which the ambient temperature remains between 15°C and 30°C (60°F to 85°F).
• Select a location in which the relative humidity remains between 30% - 40%.
• Select a location in which there is a short, direct path to the fume exhaust system.
• Set the LV-290 on a floor surface that is completely even.
• Make sure your smoke or fire detection system in the immediate area is functioning.
• Setup the machine to be apart from the wall for at least 60 cm (2 feet).
1.7 Noise Test
Test Conditions: measured at a distance of 1 meter from the surface of the machinery and a height of 1.6 meters
from the floor or access platform.
• LV-290 Sound Test Result: 49.8 dB
