Important Safety Information
Safety Instructions
General and Personal Safety Precautions
[PERSONAL SAFETY]
For personal safety, observe the following general precautions:
A second person should be available to disable the system in an emergency.
Wear appropriate protective gear that fits comfortably.
Do not wear loose-fitting clothes. If you are wearing a long-sleeved shirt, fold the cuffs up your
arm.
Never wear gloves close to moving parts.
Necklaces, ties and scarves should be tucked inside shirts.
Long hair should be covered.
[ELECTRICALTOOL SAFETY]
When using Electrical Tools make sure to:
Use tools that are in good operating order. Any tool that appears electrically or mechanically
faulty must be labeled and sent immediately for repair.
Make sure that you are electrically insulated when using electrical tools. Wear rubber-soled
shoes and stand on a dry surface.
If, during the use of electrical equipment, you feel an electrical discharge (e.g. a tickling
sensation on your skin) immediately stop using that tool. Label it, and send it for repair.
[GENERAL SITE SAFETY REQUIREMENTS]
Fire extinguishers must be in working order and within easy reach.
The main power supply switch must be easily accessible.
The system site must be suitably illuminated from all sides.
Before operation, carefully read the warning labels on your Cutting plotter unit as well as the
cautions and warnings in this manual.
Connect the Cutting plotter to a properly grounded power outlet. Make sure the voltage level of
the Cutting plotter matches that of the power source.
Don't dissemble the unit while system power is on since the power supplies inside contain high
voltage.
Never leave the machine unattended during operation.
Follow the instructions on maintaining and cleaning your system. Not only will this enable you
to utilize your machine efficiently, but it will also ensure that your machine runs safely.
