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.
Keep your hands away from moving parts.
Necklaces, ties and scarves should be tucked inside shirts.
Long hair should be covered.
[ELECTRICAL TOOL 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.
