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.
