A. Foreword
1. Appreciation
ThankyouforchoosingM20series-Gravograph.
Gravotechispleasedtocountyouamongtheusersofitsengravingandtraceabilitysolutions.
For help, contact Gravotech.
For more information on products, visit www.gravograph.com website.
2. Information
To ensure security and productivity, read this manual before starting-up the equipment.
It provides details about the installation and use of the equipment.
Keep this manual in case you need to refer to it.
Fortheattentionofusershavinganindividualcardiacassistdevice󰄈tted:
Our equipment is designed and manufactured with the greatest care in order to
guarantee their compliance with the EMC Directive currently in force. This means
that the levels of electromagnetic emissions produced by this equipment when in
operationarelimitedanddonotexceedthethresholdsde󰄈nedbytheDirective.
However, multiple factors make it impossible to guarantee the total absence of risk
forusershavingacardiacassistdevice󰄈tted.Consequently,itisrecommendedthat
standing for a prolonged period within less than 1 m (3.281 ft) of an operating machine
should be avoided.

F. Safety
1. Recommendationsandsafety
Personnelsafety
The machine is designed for light engraving only and under no circumstances should it be used for
other applications.
Do not use this marking equipment in an explosive environment.
Do not use this machine for routing or intensive cutting operations. Do not use this machine for wood
work.
Never hold the materials for engraving by the hands. Use only Gravograph clamping systems designed
for the machine.
During engraving operations, use this machine with a (regulating or suction) nose in order to prevent
󰄉yingswarf.
Donotstartengravingwithout󰄈rstensuringthattheobjecttobeengravedissecurelyclamped.
Never take hold of the material for engraving when engraving is in progress.
Interrupt engraving by means of the function provided for this purpose on the machine control panel.
Keep away from the area above the machine.
Ensure that people are kept clear of the area of travel of the moving parts of the machine and that no
objectsriskobstructingtheirmovement.
