Safety Precautions

"Safety Precautions" describe items to prevent injury to any persons or

cause other physical damage and which are necessary for the safe op-

eration of the machine.

1. Basic Precautions

• Do not open the cover on the V. Bend Detection Unit.

The semi-conductor laser in the V. bend detection unit has a maxi-

mum of 5.2 mW laser emission power.

If you look at it directly, your eyes might be injured. Never open the

cover on the V. bend detection unit.

1. Basic Precautions

Laser Indications

• Safety in laser emission is assured with normal operation of the laser

emission lamp. Before the laser is actually used, turn the power of the

lamp to "ON". If the laser emission lamp's turn-on cannot be con-

firmed, then it may be broken. In such case, do not use the V. bend

detection function, and always contact our marketing department or

sales agency to ensure safety.

• The danger level and classification according to JIS C6802 and

IEC60825-1, or CRF-Parts1040 are as follows:

Class 1, Class 2 and Class 3 show the danger levels for the laser

beam. Each has been defined, according to JIS C6802 and

IEC60825-1, or CRF-Parts1040, as follows:

Class1 : Safe design laser beam

Class2 : This laser beam is emitted within the wavelength range

between 400 and 700 nm. It is not actually safe, but

eyes could be protected by normal bodily reactions

including blinking.

Class3A : With this laser beam emitted within the wavelength

range between 400 and 700 nm, eyes could be pro-

tected by normal bodily reactions including blinking.

For laser beams emitted within other wavelengths, the

danger level for naked eye is not larger than that in

Class 1.

Class3B : If this laser beam enters an eye directly from its source,

it is dangerous. It is usually safe to look at a reflected

beam.

"Class 1" is applied to the laser power emitted from the V.

bend detection unit, which is assumed to be of safe design,

based on the related regulations (JIS C6802, IEC60825-1 or

CRF-Parts1040).

"Class 1" is indicated on the main machine and the V. bend

detection unit.
