LONGER LASER ENGRAVER LASER B1 20W/30W

1. We strongly recommend placing the machine in a well-ventilated room, and at the same time, the door of the room has a sealing effect and the windows have curtains, so as to effectively avoid looking directly at the laser beam and some smoke and steam , Particles
   and other highly toxic substances. At the same time, you can pay attention to the LONGER products (cover) in the follow-up.

2. The high-energy diode laser beam can produce extremely high temperatures and significan amounts of heat as the substrate material is burned away while engraving and cutting. Some materials are prone to catch fire during cutting operations creating flame, fumes and smoke.

3. Although the Laser B1 has a built in flame sensor, this technology should NOT be considered 100% accurate and should be seen only as a warning system.

4. P.S. During the working process of Laser B1, if a flame is found, the machine will stop the laser and make a sound to indicate abnormal conditions. Please pay attention to the working status of the machine.

5. During operation to ensure that any flare ups/ flame are properly contained and extinguished

LASER ENGRAVER INTRODUCTION

ATTENTION

1. The Laser B1 engraves and cuts materials by the means of a high-energy diode laser beam. The hazards associated with a high-energy diode laser beam include the possibility of fires, generation of hazardous and/or irritating toxic fumes, but more importantly damage to eyes and skin
2. Laser engravers are divided into several internationally valid classes based on their performance and the risk of injury.The Laser B1 falls into the Class IV (Class 4 IEC standard focus on the American FDA classification).
   Laser class| Class Definition
   ---|---
   Class I| Class I levels of laser radiation are not considered to be hazardous.

Class IIa

| Class IIa levels of laser radiation are not considered to be hazard- ous if viewed for any period of time less than or equal to 1×10³ seconds but are considered to be a chronic viewing hazard for any period of time greater than 1×10³ seconds.

Class II

| Class II levels of laser radiation are considered to be a chronic viewing hazard.

Class IIIa

| Class IIIa levels of laser radiation are considered to be, depending upon the irradiance, either an acute intrabeam viewing hazard or chronic viewing hazard, and an acute viewing hazard if viewed directly with optical instruments.

Class IIIb

| Class IIIb levels of laser radiation are considered to be an acute hazard to the skin and eyes from direct radiation.

Class IV

| Class IV levels of laser radiation are considered to be an acute hazard to the skin and eyes from direct and scattered radiation.haz- ard to the skin and eyes from direct and scattered radiation.and eyes from both direct and scattered radiation.

The high energy laser beam can cause severe eye damage, including blindness and serious skin burns.Improper use of the controls and modification of the safety features may cause serious eye injury and burns.
Please wear Personal Protective Equipment (PPE, safety glasses are designed to filter specific ranges of laser wavelength. The Laser B1 safety glasses provid- ed are specific for LONGER Laser Module;) when using the engraver.

DO NOT look directly into the laser beam;
DO NOT aim the laser beam at reflective surfaces;
DO NOT operate the laser without PPE protection for all persons nearby in the proximity of the Laser B1;
DO NOT allow unsupervised access to the Laser B1 to children; DO NOT allow access near the Laser B1 to pets;
DO NOT modify or disable any safety features of the laser system; DO NOT touch the high energy laser beam;
