Guidelines for Normal Use
1. Appoint a Laser Safety supervisor. Ensure that the supervisor has as much expertise and experience
with lasers and laser equipment as possible.
The supervisor, who will be in charge of the laser key switch, is responsible for familiarizing users
with safety issues and for coordinating laser marking.
2. Partition off all areas that may be exposed to laser light.
The supervisor is responsible for posting signs to keep unauthorized personnel out of the marking
area.
3. Install the Laser Marker on a solid, level surface.
Do not mount the Laser Marker mounted at an angle or on its side, as damage may result.
(Excluding the oscillator)
xTo prevent errant marking, place workpieces on the same stand as the oscillator so that the
workpieces do not vibrate during marking.
xUse only power supplies meeting the following criteria: single-phase 100VAC to 240VAC
(+6%/-10%) (50/60 Hz ± 3%) with capacity of at least 1kVA.
xBe sure to ground the unit with a Class D ground.
4. To ensure optimal marking quality, use the Laser Marker in a location where ambient temperatures
are 41ºF to 95ºF (5°C to 35°C), free of sudden temperature fluctuations and the relative humidity is
40% to 80%. Do not use the marker in any of the following locations:
xLocations with excessive dirt, dust, or oil mist
xLocations in which the unit may be subject to vibration or impact
xLocations in which the unit may be exposed to chemicals
xLocations near sources of high-frequency noise, or
xLocations in which condensation may form on the unit's surface.
5. If the room temperature changes quickly (as when a heater is turned ON in cold weather), moisture
may condense on the optical components, resulting in fogging or collection of dust.
Avoid sudden changes in temperature. Under the conditions in which condensation may occur, wait
for a period of time after turning the unit ON before beginning operations.
6. If the exterior of the unit becomes soiled, wipe with a soft dry or lightly moistened cloth.
Clean heavily soiled areas with a cloth moistened with diluted neutral detergent or alcohol. Do not
use paint thinner, benzene, or similar chemicals, which may discolor or damage the unit.
7. Never place screws or other foreign objects inside the marker. Such objects can damage the unit.
8. Operate the switches and buttons gently by hand.
Applying excessive force or using the tip of a screwdriver, pen, or other instrument may damage the
Marker.
9. Operate only one switch or button at a time.
Attempting to operate several at a time may damage the Marker.
10. Do not turn the main switch for the Control Unit OFF while a computer is connected to the Control
Unit. Instead power down the computer first, followed by the Control Unit.
