Relative Standards; Laser Marker (Models C 12Lch/C 12Fch) - Hitachi C 12LCH Technical Data And Service Manual

Standards, regulations and guidelines for the safe use of laser equipment.

[The U. S. A.]

There is a standard "Complies with 21 Code of Federal Regulation (21 CFR), Chapter 1, Subchapter J, Part 1010

and 1040" established by the Center for Devices and Radiological Health (CDRH) of the Food and Drug

Administration (FDA). Standards, regulations and guidelines of the other countries are under investigation.

The Models C 12LCH and C 12FCH are equipped with the laser marker that complies with the U. S. A. standard,

FDA Complies with 21 CFR, Food and Drugs, Part 1040 "Performance Standard for Light-emitting Products",

Class II. The Class II laser is defined as follows:

The laser power is low and it is safe by the protective measures such as blinking. However, it is dangerous if

the operator's eyes are exposed directly to the laser for a protracted period.

The operator can use the laser equipment without particular training and instruction.

The amount of light exposure (output) is 1mW or less at the position where the operator can be exposed to the

laser radiation during operation.

Wave length

(nm)

> 400

< 710

The saw blade unit prevents access of the operator's eye to the laser emitting aperture less than 65 mm.

In addition, the amount of light exposure (output) is 1 mW or less (about 0.4 mW) at this position. Thus the

Models C 12LCH and C 12FCH satisfy the Class II requirements adequately. There is no ill effect on the

operator's body if looking at the laser line on the workpiece during operation.

CAUTION: (1) Be sure to disconnect the power cord plug from the receptacle before removing the laser

marker for repair. If it is unavoidable to check the operation of the removed laser marker

with the power turned on, face the laser emitting aperture to the ground to show the laser

line on the ground.

(2) Laser radiation when open. DO NOT STARE INTO BEAM OR VIEW DIRECTLY WITH

OPTICAL INSTRUMENTS.

The lifespan of the laser marker in the Models C 12LCH and C 12FCH are about 2,160 hours. (About three

years: 4 hours of use/day x 180 days/year)
