SAFETY PRECAUTIONS
General
This Operator's Manual describes the Operation and Maintenance of the
LMV700(E) Nd:YVO4Laser Markers, and provides instructions relating to its
SAFE use. Procedures described in this manual must be performed as detailed by
qualified and trained personnel.
For SAFETY, and to effectively take advantage of the full capabilities of the Laser
Marker, please read this instruction manual and the Laser Safety Manual (Part
Number 990-502) thoroughly before attempting to use the laser.
After reading this manual, retain it for future reference when any questions arise
regarding the proper and SAFE operation of the Nd:YVO4Laser Marker.
Operation
When operating or servicing the Laser Marker unit, always wear Protective
Goggles having an optical density of at least 7+at a wavelength of 1064 nanometers
for the operation of the LMV700(E) Marker.
Appoint a Laser Safety Officer. The Laser Safety Officer (LSO) must provide
personnel with sufficient training so that personnel can operate, maintain and
service the Laser Marker safely. The LSO must take charge of the key to the Key
Switch to ensure that only qualified and authorized personnel operate the Laser
Marker.
Establish and control a dedicated Laser Operation Area. The Laser Safety Officer
must isolate the Laser Operation Area from other work areas and display signs
warning that the Laser Operation Area is off-limits to unauthorized personnel.
Maintenance/Service
Before performing any maintenance on the Laser Marker, read Chapter 4,
Maintenance thoroughly. Use the appropriate tools for terminating the connecting
cables, being careful not to nick the wire conductors.
Procedures other than those described in this manual or not performed as
prescribed in this manual, may expose personnel to electrical and/or laser radiation
hazards.
Do not modify the Laser Marker without prior written approval from Miyachi
Unitek Lasers.

xBe sure to read each of the instructions, as
they are all important for safe operation.
xThe meaning of the words and symbols are
as follows:
DANGER
Do not touch inside the Laser Marker when it is switched ON.
Doing so may result in electric shock.
Never attempt to disassemble, repair, or modify the Laser Marker.
Doing so may result in electric shock or fire.
Refrain from any mechanical adjustment other, than maintenance specifically described in the
operation manual.
Never expose eyes or skin to laser irradiation.
Exposure to direct or scattered laser light is extremely hazardous.
Direct exposure of the eye to laser beams may result in blindness.

WARNING
Wear protective eyewear.
Always wear protective eyewear when using the Laser Marker.
Keep in mind that exposure of the eyes to direct laser irradiation may result in blindness,
even when wearing protective eyewear.
Never aim the laser at any parts of your own body or other people.
Exposure to laser beams will cause severe burns.
Never aim the laser at yourself or at anyone else.
Do not touch workpieces during or just after marking.
Workpieces may still be very hot.
Use only the specified cables. Make sure they are firmly connected.
Using cables of inadequate current capacity or connecting cables loosely may result in
fire or electric shock.
Avoid damaging power or connecting cables.
Do not step on, twist, or pull cables.
Damaged cables may result in electric shock, short circuits, or fires.
To repair or replace cables, contact your Miyachi dealer or Miyachi Corporation.
Stop using the Laser Marker if any problems arise.
Continuing to use the Laser Marker in the presence of abnormalities (fumes, unusual
sounds, excessive heat, smoke, and so forth) may result in electric shock or fire.
In this case, immediately turn the Laser Marker OFF and contact your Miyachi dealer or
Miyachi Corporation.
Ground the Laser Marker.
Failure to ground the Laser Marker may result in electric shock if the Laser Marker is
damaged or if electrical leaks occur.
People using pacemakers must NOT approach the Laser Marker.
Unless a physician has consented, pacemaker users must not approach the Laser
Marker in use, or even approach the working area.
The Laser Marker generates electromagnetic fields that may affect pacemaker function.

CAUTION
Avoid spilling or splashing water on the Laser Marker.
The presence of water on electrical parts may result in electric shock or short circuits.
Liquid spills may degrade the unit's insulation, resulting in electric leaks or fire.
Use the appropriate tools to terminate the power cable (wire strippers, crimp
tools, etc.).
Failure to use the appropriate tools may result in damage to the wire core, resulting in fire or
electric shock.
Install the Laser Marker on a solid, level surface.
Should the Laser Marker tip over or fall, injury or damage to the unit may result.
Keep combustible materials away from the Laser Marker.
Sparks or spattering material may ignite combustible matter.
To avoid the risk of fire, never apply the laser beam to flammable or combustible materials.
During use, do not cover the Laser Marker with a blanket, cloth, or similar
articles.
When using the Laser Marker, do not cover with a blanket, cloth, or similar articles.
The Laser Marker may become extremely hot, resulting in fire.
Do not use the Laser Marker for any purpose other than laser marking.
Using the unit for nonspecified applications may result in electric shock or fire.
Wear protective gear.
Use protective gloves, long-sleeve garments, leather aprons, or other appropriate protective
gear. Sparks or spattering material may burn the skin on contact.
Keep a fire extinguisher nearby.
Keep a fire extinguisher in the marking area in case of fire.
