Chapter 1 Safety Precautions
• Appoint a safety supervisor with as much expertise and experience with lasers and laser equipment
as possible. The supervisor, who will be in charge of the laser key switch, should familiarize users
with safety issues and coordinate laser marking.
• Partition off the area which might be exposed to the laser beam. A supervisor should control this work
area and post signs to keep out unauthorized personnel.
• Install the Laser Marker on a solid, level surface. Using the unit (other than the Head Unit) at an angle
or on its side may damage it.
- To prevent distorted marking, put workpieces on the same stand as the Head Unit so that
the workpieces do not vibrate during marking.
- The power supply must be single-phase 100 V AC to 240 V AC, with capacity of at least 10
A.
- Be sure to ground the unit with a Class D ground.
• To ensure optimal marking quality, use the Laser Marker in a place where the ambient temperature is
5 to 35 °C, where the relative humidity is 40 to 80%, and where it is not subject to sudden
temperature fluctuations. In addition, do not use the marker in the following places:
- Where there is excessive dirt, dust, or oil mist
- Where the unit is subject to vibration or impact
- Where the unit is exposed to chemicals
- Where there is a nearby source of high noise
- Where moisture may condense on the unit
• If the room temperature changes quickly (as when a heater is turned on in cold weather), moisture
may condense on the optical elements. Dust may adhere or the elements may become fogged up
with condensation. Thus, avoid sudden temperature changes. If condensation may have occurred,
wait for a while after turning the unit on before starting operation.
• The exterior of the system should be wiped clean using a soft or moist cloth. If the exterior is
particularly dirty, wipe it clean using diluted detergent or alcohol.
Do not use paint thinner, benzine, or similar chemicals, which may discolor the unit or deform parts.
• Do not place screws or other foreign objects inside the marker. This may damage the unit.
• Operate the switches and buttons gently by hand. Applying excessive force or using the tip of a
screwdriver, a pen, or other instrument may damage or break the switches or buttons.
• Operate only one switch or button at a time. Operating several switches or buttons at a time may
damage or break the unit.
• Do not turn off the power switch while a computer is connected to the Control Unit.
• If a computer is connected, it will continue to access the memory card for about 15 seconds after
going offline. During this time, do not turn off the power switch of the Control Unit.
