Do not use

32、 laser engraver while you are tired or under theinfluence of drugs, alcohol or medication. A moment of inattention while operatinglaser engravers may result in serious personal injury.b) Use personal protective equipment. Always wear eye protection appropriatefor class of laser engraver. Protective

33、equipment such as heat and cut resistantgloves used when work pieces are hot or have sharp edges will reduce personalinjuries.c) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothingand gloves away from moving parts. Loose clothes, jewelry or long hair can becaught in movin

34、g parts.d) Be careful removing work pieces from the laser cutter. Cutting with a laserincreases the temperature of the work piece and the temperature of the workpiece may remain high after laser cutter stops operating. Touching hot work piecesbefore they cool down may result in burns.e) Do not let f

35、amiliarity gained from frequent use of laser engravers allow you tobecome complacent and ignore laser engraver safety principles. A careless actioncan cause severe injury within a fraction of a second.4) Laser engraver use and carea) Prevent idle laser engraver from being used by children and do not

36、 allowpersons unfamiliar with the laser engraver or these instructions to operate thelaser engraver. Laser engravers can be dangerous in the hands of untrained users.b) Maintain laser engravers. Check for misalignment or binding of moving parts,breakage of parts, coolant leaks and any other conditio

37、n that may affect the laserengravers operation. If damaged, have the laser engraver repaired before use.

38、BUTION WITHOUT PERMISSION FROM ULc) Use the laser engraver in accordance with these instructions, taking intoaccount the working conditions and the work to be performed. Use of the laserengraver for operations different from those intended could result in a hazardoussituation.5) Servicea) Have your

39、laser engraver serviced by a qualified repair person using onlyidentical replacement parts. This will ensure that the safety of the laser engraver ismaintained.8.14.1 Addition:The additional safety instructions as specified in Clause 8.14.1.101 shall be given. This part may beprinted separately from

40、 the General Power Tool Safety Warnings.8.14.1.101 Safety instructions for laser engraversLaser engraver safety warnings:a) WARNING: Never expose yourself to the laser beam since it may cause physicalburns and can cause severe eye damage. Proper use and care of this laser engraver systemare essentia

41、l to safe operation.b) Never operate the laser engraver system without constant supervision of the cuttingand engraving process. Exposure to the laser beam may cause ignition of combustiblematerials and start a fire.c) Never use PVC or other nonconductive duct materials for the exhaust system. Stati

42、ccharges may build up and may cause a risk of fire or explosion.d) Always use fire rated rigid or flexible metal or metalized ducting in the exhaustsystem. Non-fire rated exhaust ducting may increase the risk of fire.e) Always inspect the exhaust fan and duct work for obstructions and ensure proper

43、airflow exists before each use. Unobstructed and properly maintained exhaust fan and duct workwill reduce the risk of fire and effectively extract caustic fumes and smoke.f) Never engrave or cut any unknown material. Only engrave materials recommended bythe manufacturer. The vaporization/melting of

44、many materials, including but not limitedto PVC and polycarbonates, can give off hazardous fumes. Always refer to the Safety DataSheet (SDS) from the material manufacturer to determine the response of any work material toextreme heat (burning/fire hazard) to prevent hazards.g) Always use the air ass

45、ist as recommended by the manufacturer, especially whilecutting. Cutting movements are relatively slow and apply an extremely large amount ofheat to the work piece. Avoid the build-up of heat in order to reduce the risk of fire.h) Keep the interior of the laser cutter, including the table tray, clea

46、n and free of debris.Clean the laser. A build-up of cutting and engraving residue and debris is dangerous and mayincrease the risk of fire.i) Never look into the beam of the alignment laser.
